DATASHEET

Modbus Master/Slave Communication Module

MVI56E-MCM/MCMXT

The MVI56E Communication Module allows for Modbus Master and/or Slave connectivity from Rockwell Automation® ControlLogix® processors to Modbus RTU/ASCII devices. Each MVI56E port can be configured as a Master or Slave.

The MVI56E-MCM and MVI56E-MCMXT act as input/output modules on the ControlLogix backplane, making Modbus data appear as I/O data to the processor.

Two independently configurable serial ports can operate on the same or different Modbus networks. The MVI56E-MCM is designed for standard process applications and the MVI56E-MCMXT is designed for the Logix-XT™ control platform, allowing it to operate in extreme environments. It can tolerate higher operating temperatures, and has conformal coating to protect it from harsh or caustic conditions.

Features Benefits

Backward Compatibility

All MVI56E products are backward-compatible with earlier MVI56 modules allowing direct replacement without the need to change existing controller programs

10,000 Word Database Allows you to gather more data from your devices, which improves operational performance

Enjoy Enhanced features and flexibility without incurring expensive reprogramming costs

Add-On Instruction Module configuration stored within the RSLogix™ 5000 project (ACD file)

No additional programming or configuration software is required

Add-On Instruction for RSLogix 5000 version 16 or higher cuts development time and costs

CIPconnect® Enabled Facilitates remote user access across the ControlLogix backplane through Rockwell Automation’s 1756-ENBT module

Configure, diagnose, and analyze process data and communications status

Bridge through multiple ENBT/CNBT links to connect to MVI56E-MCMs installed in remote chassis for configuration and diagnostics

Add-On Profile Simplifies adding the module in an RSLogix 5000 project

Configuration

The module configuration is defined in the Add on Instruction. The AOI is fully commented, and includes user-defined data types, ladder rungs and controller tags. The AOI can be used without modification for most application.

The MVI56E-MCM User Manual and sample configuration provide a quick and easy example with step-by-step instructions on how to move data through the module from the Modbus network to the processor.

General Specifications Backward-compatible with previous MVI56-MCM version

Single Slot - 1756 ControlLogix® backplane compatible

10/100 MB Ethernet port for network configuration and diagnostics with Auto Cable Crossover Detection

User-definable module data memory mapping of up to 10,000 16-bit registers

4-character, scrolling, alphanumeric LED display of status and diagnostic data in plain English

ProSoft Discovery Service (PDS) software finds the module on the network and assigns a temporary IP address to facilitate module access

Supports RIUP (Remove and Insert Under Power)

Functional Specifications The MVI56E-MCM will operate on a Local or Remote rack (For remote rack applications with smaller data packet size please refer to the MVI56E-MCMR product)

Supports Enron version of Modbus protocol for floating-point data transactions

PCB includes powerful Modbus network analyzer

Special functions (command control, event commands, status, and so on) are supported by message transfer (unscheduled) using the MSG instruction

Error codes, network error counters, and port status data available in user data memory

Slave Specifications The MVI56E-MCM module accepts Modbus function code commands of 1, 2, 3, 4, 5, 6, 8, 15, 16, 17, 22, and 23 from an attached Modbus Master unit. A port configured as a Modbus Slave permits a remote Master to interact with all data contained in the module.

This data can be derived from other Modbus Slave devices on the network, through a Master port, or from the ControlLogix processor.

Master Specifications A port configured as a virtual Modbus Master device on the MVI56E-MCM module actively issues Modbus commands to other nodes on the Modbus network. Up to 325 commands are supported on each port. Additionally, the Master ports have an optimized polling characteristic that polls Slaves with communication problems less frequently.

The ControlLogix processor ladder logic can issues commands directly from ladder logic or actively select commands from the command list to execute under ladder logic control.

ControlLogix™ Modbus Integration

General Modbus Specifications Communication Parameters

Baud Rate: 110 baud to 115.2 kbps Stop Bits: 1 or 2 Data Size: 7 or 8 bits Parity: None, Even, Odd RTS Timing delays: 0 to 65535 milliseconds

Modbus Modes RTU mode (binary) with CRC-16 ASCII mode with LRC error checking

Floating Point Data Floating point data movement supported, including configurable support for Enron and Daniel implementations

Modbus Function Codes 1: Read Coils Status 2: Read Input Status 3: Read Holding Registers 4: Read Input Registers 5: Force (Write) Single Coil 6: Preset (Write) Single Register 8: Diagnostics 15: Force (Write) Multiple Coils 16: Preset (Write) Multiple Data Registers 17: Report Slave ID 22: Mask Write 4x Register 23: Read/Write 4x Registers

Modbus Master Specifications Command List Up to 325 commands per Master port, each fully configurable for function code, slave address, register to/from addressing and word/bit count.

Optimized Polling Configuration options allow Master ports and commands to be optimized to poll slaves with communication problems less frequently.

Command Status/Error Monitoring

Command Status or Error codes are generated for each command as it executes, allowing careful monitoring of communication health between the Master and its Slaves.

Slave Polling Control Master Port maintains a Slave Status list of all network Slaves. Polling of each Slave may be disabled and enabled using this list.

Modbus Slave Specifications Full Memory Access A port configured as a Modbus Slave permits a remote

Master to read from or write to any of the 10,000 registers that make up the user memory database.

Multi-source Slave Data Data presented at the Slave port can be derived from other Modbus Slave devices on a different network through the module’s Master port or from the processor tag database.

Node Address 1 to 247 (software selectable)

Status Data Slave port error codes, counters and statuses are available separately for each port when configured as a Slave
