  1. Hello; Need some information about the correct procedure of replacing an I/O TM2AMI4LT module. My problem: have 3 same modules TM2AMI4LT and I think someone changed their position. Now the system is showing multiple errors on HMI display. Therefore, machine stays on hold, safe lock.   What I like to know is; Do I need to upload the application of the system after I have replaced a I/O module ?   Second question: If I replace a I/O TM2AMI4LT module for a new one, does the system will function as before after startup, this without an upload?   Last question: Does an I/O TM2AMI4LT contains a “fixed” software address, once programmed?   Hope to read your advise soon.
  2. Dear all, I have an Allen Bradley Control panel with SLC L542C 5/04 CPU, it is used to control an RO water desalination unit, unfortunately the CPU has a fetal Fault and need to be replaced, the only available one is 1747-L542A 5/04 CPU, the problem is when downloading the PLC Program to the new CPU, using RSLogix 500, it failed due to smaller memory of A series CPU 24K while the C series CPU was 32K, is there any way to reduce the program size to be used with 1747-L542A 5/04 CPU? what is a proper way to get the new CPU run with the control program? Thank you all in advance.

  5. Second day using Proficy. Needing to cookie cut from a template program that references I/O devices in the HMI variables. Currently I have to edit each one individually, and there are thousands of tags to be changed, times the number of cloned systems I am creating. How can I automate this mind numbing, and error prone work?
