Modernizing Extinct Process Controls

TISoft to Studio 5000


This utility converts (migrates, translates) TI505 programs that were created with the TISoft programming software to Studio 5000, in other words TI 505 to ControlLogix (CLx).


Each register will be converted into a one-dimentional array of identical data type. X/Y (tag name IO), C as BOOL; WX/WY (tag name WIO), V, K as INT; TMR as TIMER; CTR as COUNTER. X and Y use the same tag array. WX and WY use the same tag array.


The ladder logic is converted using Smart Translation Technology. PID Loops can be converted into PID or PIDE instructions. Special Functions convert into Structured Text.

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:

Synonyms are converted to address comments. Descriptors are ignored. Comments are converted to rung comments.


Here are three options for remapping the I/O:

NONE: I/O addresses stay at their image register address. For example X97 will become IO[97].
AN-X: I/O addresses will be remapped to an AN-X-TI module (See ProSoft under Resources). Alias’ will be created that point to the AN-X-TI.
1756: I/O addresses will be remapped to 1756 I/O. You must provide the CLx I/O configuration and remap cross reference.

If you are converting from SIMATIC Application Productivity Tool — APT, please contact us.


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

Please note:

We count every two lines of Special Functions code as one rung.
We count each PID loop as one rung.
We count each Alarm as one 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: VP5, KMM, VMM, …

Satisfaction Guaranteed

We guarantee that your program will be converted correctly. (no fine print)
