Revamp PLC2 to Controllogix

[bekrab]

Is there any tool that can convert PLC2 program to Controllogix CPU?
Or we need to re-write all ladder by manual.

Is there any suggestion or concern when we do this conversion?

Thank in advance.

At best it would be a two-step process of converting PLC-2 to PLC-5 logic, then converting PLC-5 to ControlLogix.

There was a DOS-based AI-2 to AI-5 conversion program but it's been obsolete and unavailable for 15 years.

I would strongly recommend re-writing the program for ControlLogix by hand. The PLC-2 didn't even have subroutines or typed data storage files.

There are some hardware compatibility issues when converting 1771 I/O from the PLC-2 era (1977 to 1984) to use with modern ControlLogix and RIO adapters. These are well detailed in RA Knowledgebase Document 16474 (TechConnect).

Thank you for your recommendation.

We will try on this step.
