The purpose of this Amendment is to issue any/all Answers to Questions asked since the first Q&A Amendment

The deadline for this Solicitation has been extended FROM Aug. 21, 2026, 11:00 AM MDT TO

Aug. 26, 2026, 11:00 AM MDT.

Solicitation 140R6026Q0112 Amendment No. 0002 SF-30 Continuation Pgs

QUESTION: CPU identification. Please provide the Siemens PLC CPU order number (MLFB) and product family for the target system:

• S7-300

• S7-400

• S7-1200

• S7-1500

• Other (please specify)

ANSWER: Our system utilizes both the S7-300 and S7-400.

QUESTION: Nameplate data. If permitted, a photograph of the CPU nameplate showing the

Siemens MLFB and firmware version. If imagery is restricted, a transcription of the MLFB and firmware revision from the equipment inventory or O&M records is sufficient.

ANSWER: Each system has (Qty 2) CPU 414-2 (6ESY 414-2XG03-0AB0) and a CPU 318-2 (318-

2AJ00-0AB0).

QUESTION: Prior engineering software. Which programming environment was previously in use?

• STEP 7 Classic (V5.x)

• TIA Portal

• PCS 7

• Unknown

ANSWER: We need a license for STEP 7 Version 5.6 (we currently have one in use, need a second license). Our CPUs are too old for anything newer than this version. We also have TIA Portal on our current license.

QUESTION: Scope of supply. Does the requirement cover the engineering software license only, or does it also include programming hardware — programming device/laptop, communication adapter (e.g., PC Adapter USB A2, CP 5711), and connecting cables?

ANSWER: We only require software licenses and USB/Serial Adapter as outlined in the solicitation.

Solicitation 140R6026Q0112 Amendment No. 0002 SF-30 Continuation Pgs

QUESTION: Communication interface. Which interface is available on the CPU for connection to the engineering station?

• MPI

• PROFIBUS

• PROFINET / Ethernet

• Other (please specify)

ANSWER: We primarily connect via MPI, but our system utilizes Profibus and Ethernet as well.

QUESTION: Operational objective. What is the intended use of the software?

• Online troubleshooting/diagnostics only

• Program backup and upload

• Program modification and download

• Full PLC replacement or migration

ANSWER: Software needs to be able to troubleshoot, modify the program, load the program onto the CPU including uploads or downloads.

QUESTION: Existing license data. Any available license information from the prior engineering station — license number, Certificate of License, Automation License Manager screenshot, or software version record — to determine whether an upgrade, competitive upgrade, or new full license is the appropriate and lowest-cost path.

ANSWER: We currently have the following licenses purchased. We would like an additional license for each of these to install on a second backup laptop.

Siemens Step 7 Professional, License Only, p/n 6ES76581EX780HY5

Siemens Simatic CFC, License Only, p/n 6ES76581EX780YH5

Siemens Softnet-IE, License Only, p/n 6GK17041CW250AK0

Siemens, PC Adapter, Serial to USB, p/n 6GK15710BA000AA0

QUESTION: System configuration. If permitted, a photograph or description of the PLC rack/cabinet configuration, including any communication processors (CP), interface modules

(IM), or distributed I/O present.

ANSWER: With the above system CPUs, we also utilize a Comm Card CP 343 (6GK7 343-1EX10-

0XE0) and CP 443-1 (6GK7 443-1EX11-0XE0).
