This utility converts (migrates, translates) AB PLC2 (1772) programs that were created with the 6200-PLC2 programming software to SoftPLC TOPDOC NexGen. This conversion is a direct translation into SoftPLC (4.x). It is NOT a double hop (PLC2 > PLC5 > SoftPLC).


The data table is converted to a single data file (N11) as type Integer. All data will change from BCD to decimal in the conversion process. Addresses will change from octal to decimal. For example, an address of 370/17 will become N11:248/15. New addresses will be created for timers, counters, and control. For example, timer address 040 will become T4:40 as type Timer.


The ladder logic is converted using Smart Translation Technology.

Most instructions will convert without any issues. Some instructions convert but have additional logic added by the conversion utility to emulate the original instruction. A few instructions cannot be converted. They will be noted in the conversion log.


All documentation converts with the following exceptions:

Symbols are converted to tags. Some characters cannot be used in tag names. These tags will be renamed.


There is one option for remapping the I/O:

NONE: I/O addresses stay at their I or O address.
