3 Operation

3.1 Overview

The Speed Input Module (SIM) is a high-speed interface between speed sensing devices and a PLC. It simultaneously operates as a stand-alone device for overspeed detection. Up to four independent speed sensor channels can be configured via a serial interface.

All magnetic pickup styles are supported. Passive magnetic sensors (variable reluctance) are widely used because of their known failure modes. Active probes (Hall Effect or zero speed) can be used with the SIM by wiring into different terminals on the module. Both TTL and supply tracking versions of active probes are compatible with the SIM. Each of the input channels can be configured for a different style.

In order to interface with Allen-Bradley and other similar PLCs, the SIM incorporates a communication network interface module.

As an overspeed detection device, each channel has its own setpoint and trip relay output.

Figure 1

3.2 Hardware Design

Inside the SIM is an Intel Series 196 microcontroller that handles configuration, measurement, and serial communications. An additional processor is responsible for the communications interface.

All of the configuration data is stored in non-volatile memory accessible by the microcontroller. This data is available for configuration via the serial communication port.

The serial communication software runs continuously on the CPU. An external interrupt triggers the speed calculation software on a regular basis. This allows the SIM to produce speed data to the communications network on a consistent recursion rate of ten milliseconds.

A proprietary communication protocol is utilized to monitor and change the non-volatile memory and other module information.

3.3 Front Status Lights

Two status lights are visible on the front of the SIM. The following table is a description of each state and meaning.

Signal Color LED State Meaning

NORMAL green on SIM ready for operation off watchdog has timed out (see below)

OVERSPEED red on one of the four input channels have exceeded the programmed overspeed setpoint (latching) off no overspeed conditions present

Table 1

Communications Status LED’s are located on the right side of the module, close to the BNC connectors. See Appendix G for details.

3.4 Frequency Measurement

A unique frequency multiplication and counter scheme allows the SIM to measure speed with high accuracy in a short period of time. Frequencies above 100Hz are encoded within

0.025% of the selected full scale. Below 100Hz, the counter changes its calculation to monitor over a longer interval.

The input signal is shaped and fed to a phase-locked-loop that multiplies the incoming frequency. This multiplied frequency is connected to a high speed counter accessible by the microcontroller. Every ten milliseconds, the counter’s value is gathered. The counter difference between samples and the multiplier gain are used to calculate the input frequency.

Previously calculated data is stored and used in the calculation of the current frequency to produce a higher resolution measurement.

Several checks including the following are performed on the counter data to validate the frequency calculation.

When a frequency input channel transitions from zero to a valid signal, the frequency

(and resulting speed) calculation is rate limited for three seconds. This signal validation period is necessary for redundant applications where on-line replacement of the SIM is possible. Invalid frequency measurements generated from connecting a live speed signal are ignored. Once the signal is validated, no further time delays are introduced.

Rate limiting is performed to ignore momentary abnormalities in the input signal.

Execution time is measured with each scan. Subtle differences in the analog clock are known and used to compensate the measured values.

The multiplier for the input frequency is selectable based upon the desired frequency range of the input signal. The highest possible multiplier (smallest possible frequency range) should be used for the greatest measured resolution. The following selections can be made via the serial interface.

Multiplier (PLL Gain)

Maximum Input Frequency

Max Readable

RPM

8 25 kHz 32767

16 12.5 kHz 32767

32 6250 Hz 32767

64 3125 Hz 32767

128 1560 Hz 3276.7

256 780 Hz 327.67

Table 2

3.5 Speed Calculation

Rotational speed is calculated with the sensor configuration and the pulses per revolution of the shaft. Each input channel can be configured independently.

Two configuration values are available: teeth per revolution of the shaft, and an offset. In cases where a gear ratio or other arrangement exists, the number of teeth can be entered as a fractional amount with two decimal places.

Typically, the offset is not used unless the specific gear ratio cannot be entered with enough resolution to generate an accurate speed calculation.

When the smaller frequency ranges are selected (1560 Hz or 780 Hz), the speed calculation provides decimals to the user. A range of 1560 Hz selects a single decimal place and a range of 780 Hz provides two decimal places. Since the SIM produces the speed data in integer format, the decimals are provided as a multiplier in the speed calculation. For example, if the range is 1560 Hz and the actual speed is 436.75 rpm, the SIM produces a speed value of 4367

(436.75 x 10 for one decimal place). For the same speed, if the range were 780 Hz the result would be a speed value of 43675 (436.75 x 100 for two decimal places).

3.6 Overspeed Function

Each channel is configured with an independent overspeed setpoint. If the SIM calculates a rotational speed that exceeds the setpoint, the corresponding relay output is de-energized

(opening the contact) and the OVERSPEED light is lit. The overspeed relay and the light are latched in the SIM. The overspeed latch can be reset by pulsing the reset bit via the communication link (See the memory map in Appendix B) or power cycle the SIM.

The highest speed measured is captured and stored in RAM. Monitoring and clearing this value is possible from the serial communication interface.

The highest speed captured is lost if power to the module is removed

3.7 Watchdog Function

The microcontroller periodically triggers an independent monostable circuit utilized as a watchdog. In the event the processor does not trigger the monostable every eight milliseconds, a relay (available to the user as 5R) de-energizes, and the communications interface flags that the unit has failed.

Possible causes for the hardware watchdog to fail include invalid configuration, failed power-up or periodic self-tests, or faulty hardware. See the Diagnostics section below for a detailed listing of internal tests that are performed that result in a watchdog failure indication.

A watchdog counter is also available to the PLC to monitor the SIM and the communications link. An internal counter is incremented each time data is produced to the communication network. This counter is included in the memory map to be monitored by the PLC. If for any reason the counter does not change, communications to the SIM has been lost. This trigger can be utilized in the PLC to take the appropriate action.

3.8 Diagnostics

Self-diagnostics are performed by the SIM. If any fault is found, the microcontroller is commanded to set all speed and frequency data to a failed value, 65535 (-1 if signed integers are used in the PLC), and all relays are deenergized (including the watchdog). Diagnostics can be categorized into two sets of faults.

The first set is checked on power up to determine that the SIM hardware and software are configured properly and no faults exist. These tests include:

EEPROM checksum

NVM copy into RAM (access errors and checksum)

RAM access fault

The second set of tests is performed continuously while the SIM is running to ensure the module is operating properly. These include:

NVM checksum

EEPROM checksum

Invalid configuration (maximum frequency range incorrect)

Speed calculation error

Divide by zero

Serial communication fault

Timeout of 10ms interrupt routine

The fault information is communicated via the serial interface link and the communication network. See the memory map in Appendix B for further communication interface details.

4 Installation

4.1 Mounting on DIN Rail

1. Position the SIM on the DIN rail at a slight angle.

2. Hook the left side of the SIM mounting plate to the DIN rail while holding the module at a slight angle away from the DIN rail.

3. Press the SIM down onto the DIN rail until the mounting plate snaps into place.

4. If the mounting plate does not lock into place, use a screwdriver or similar device to move the spring loaded locking tab away from the DIN rail while pushing the module onto the DIN rail and release the locking tab to lock the adapter in place.

4.2 Removing from DIN rail

1. Remove all of the wiring connections by pulling out the plug connectors on both sides.

2. Move the spring-loaded locking tab (on right side of module) away from the DIN rail with a screwdriver or similar device.

3. With the locking tab held out, tilt the module away from the DIN rail and then unhook the left side.

4.3 Power Supply and Grounding

The SIM should be connected to a nominal 24 Vdc power supply. The input power should be protected by a fuse or breaker no greater than two amps. Power input is wired via the J5 pluggable connector.

Figure 2

An instrument ground should be supplied and connected to J5 Shield (S) terminal. This terminal is connected to all of the shield terminals on the module; it is not connected to chassis.

Improper shield grounding can cause invalid speed measurement or erroneous overspeed detection.

4.4 Wiring to Speed Probes

The SIM will accept either Passive or Active speed probes on each of the 4 channels. The

SIM will automatically use the probe type that is wired. Therefore, either the Passive channel, OR Active channel should be wired.

Any unused inputs should be shorted (P1 to P2) for noise immunity.

4.5 Wiring to Passive Probes

Passive speed signals are coupled through a transformer to the SIM. Terminals P1 and P2 are the 1:1 connection. If extremely low voltages are present at the passive probe, Terminals

P1 and P3 may be used, making the input an amplifying 1:2 connection. Refer to Appendix

A for input signal levels. Connectors J1 and J2 are for connecting passive probes to the SIM as shown below.

Shields can be connected to the Shield (S) terminals if a connection is made from J5 Shield

(S) terminal to instrument ground. Shields should only be terminated to a ground at one point. If a shield connection to ground is made elsewhere, leave the shields disconnected at the SIM.

4.6 Wiring to Active Probes

Active speed signals are optically isolated in the SIM. Power for the active probes is not supplied by the SIM. An external power supply should be used to power active probes. This external supply does not need to be referenced to the power supply for the SIM. Connectors J3 and J4 are for connecting active probes to the SIM as shown below.

Figure 4

Shields can be connected to the Shield (S) terminals if a connection is made from J5 Shield

(S) terminal to instrument ground. Shields should only be terminated to a ground at one point. If a connection to ground is made elsewhere, leave the shields disconnected at the

SIM.

Any unused inputs should be shorted (P1 to P2) for noise immunity.

4.7 Wiring to Relay Outputs

Each relay output is an independent, dry contact, and normally open output (Form A).

Relays one through four represent the overspeed for channels one through four, respectively.

The fifth relay is tied to the watchdog circuit. All of the relays are normally energized.

During normal conditions, all of the contacts are closed. In the case of an overspeed, the corresponding relay contacts open. For a watchdog event, all relay contacts open. Connector J6 is used to connect all five of the relay outputs as shown below.

Each Relay is protected with an internal 4 amp fuse (non-field serviceable). If any of these fuses are blown, the unit must be returned to the factory for repair.

Figure 5

4.8 PLC Communications Network

The SIM is capable of communications to a PLC over a deterministic network. This typically is ControlNet, however, other versions are available. The ControlNet interface is a redundant media, deterministic network that allows regular scheduled communication to the

PLC for real time control applications. The physical network connection is a pair of coaxial

BNC connectors at the right side of the box. The leftmost BNC is the “A” network connection and the right BNC is the “B” network connection. See Appendix G for details on the ControlNet Interface.

Data is contained in an 18 word read and a 16 word write memory space. All information is passed as integers to the PLC. See Appendix B for a detailed memory map.

Appendix D: ControlLogix ControlNet Setup For those using the SIM with the Allen-Bradley ControlLogix processor, the following example shows how to setup the ControlNet network and the application program.

D1 Register EDS File

Before attempting to configure the SIM in an application or browse it in the

ControlNet network, the Electronic Data Sheet (EDS) must be registered on the computer utilized to program the device.

With RSLinx installed on the computer, go to:

Start → Programs → Rockwell Software → RSLinx Tools → EDS Hardware

Installation Tool

Follow the instructions to ‘Add’ the EDS file for the SIM. If you do not have an electronic copy of the EDS file, copy the text in Appendix E to a text file named “83-

7278-EDS_ABS_CNT_V_1_7.eds”.

D2 Verify Installation

Utilizing RSLinx, browse to the ControlNet network containing the SIM. When the network is browsed, the SIM should be recognized with an icon representing the module. If the ControlNet node address for the SIM is shown as unknown (question mark), the EDS file was not registered successfully.

D3 Configure Software

In RSLogix 5000, you must have a ControlNet module configured in the

ControlLogix chassis that is physically connected to the SIM. Under the ControlNet module, define a ‘Generic ControlNet Module’ with the following parameters:

Appendix F: Serial Communication Interface The serial interface is a master/slave based protocol with embedded checksums. Each address is written to or read from with a separate request. A single reply is transmitted from the SIM for each command. The reply is one of three possibilities: acknowledge and return of the requested data, acknowledgement of a successful write to memory, or a not acknowledged message when the command was not understood.

The embedded message checksum is calculated as a rolling sum of each byte in the message before the checksum.

Note: Messages are shown below in hexadecimal.

Appendix G: ControlNet Communications Board The following appendix is an excerpt from the HMS Industrial Networks documentation [83-

8559 – Fieldbus Appendix AnyBus-S ControlNet, Revision 2.00]. The following diagram identifies the interfaces available to the user and their orientation.

# Description

2 Network Access Port (NAP)

3 ControlNet Channel A

4 ControlNet Channel B

5 Node # switch (x10)

6 Node # switch (x1)

7 ControlNet Status Indicators

G1 Network Access Port (NAP)

The NAP (Network Access Port) provides temporary access to the ControlNet network for diagnostics and configuration.

G2 ControlNet Channels A & B

The module is equipped with two BNC contacts for connection to ControlNet. If redundant operation is desired, both connectors are used; otherwise connector A or B is used.

G3 Node Number Switches (x10 and x1)

On a ControlNet network, each node must be assigned its own unique node address. The module features on board switches for ControlNet node configuration, providing an address range of 1 to 99.

In this example, the node address is set to 42 (4 x 10 + 2 x 1).

NOTE: If either of the switches is changed, power must be cycled to the unit to use the new address.

G4 Indicator Lights

The following diagram describes the indicator lights that are next to the ControlNet node number switches. These lights display the health of the ControlNet connection and can aid in troubleshooting communications.
