PLC Conversions

Modernizing Extinct Process Controls

Logicmaster 90-30 to Studio 5000


This utility converts (migrates, translates) GE Series 90-30 (GE 90-30) programs that were created with the Logicmaster 90-30 programming software to Studio 5000, in other words GE 90-30 to ControlLogix (CLx).


Each register will be converted into a one-dimentional array of identical data type (O,I,R as INT).
Timers and counters will have new tags created of type TIMER and COUNTER. For example, timer R00901 will become T0901.


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:

Nicknames are converted to aliases. Some characters cannot be used in tag names. These aliases will be renamed and noted in the conversion log.


Here are three options for remapping the I/O:

NONE: I/O addresses stay at their O, I, and R address
AN-X: I/O addresses will be remapped to an AN-X-GENI module (See ProSoft under Resources).
1756: I/O addresses will be remapped to 1756 I/O. You must provide the CLx I/O configuration and remap cross reference.

Conversion samples

LM 9030 Program, LM 9030 CLx (a picture’s worth a thousand words)


You must include the entire program folder in your zip file.


We convert your program, review it for accuracy, and manually cleanup the logic so that you can download it and start testing. This includes remapping the I/O if possible.
Typical conversion turn around time: 5 business days
Starting at: $2.50 (USD) per rung

What do I need to do

Upload the program from the PLC!
Save the program (<project name>.*) as a zip or 7-zip file. Do not include the path. (One PLC program per zip file.)
Your program will include file extensions such as: _main.lh1, _main.dec, _main.pdt, Lmfolder.30, …
