Modernizing Extinct Process Controls
This utility converts (migrates, translates) Allen-Bradley (AB) PLC3 (1775) programs that were created with the 6200-PLC3 programming software to Studio 5000, in other words PLC3 to ControlLogix (CLx). This conversion is a direct translation into ControlLogix (1756). It is NOT a double hop (PLC3 to PLC5 to ControlLogix (CLx)).
Each data table will be converted into a one-dimentional array of identical data type (O,I,N,D,B,A as INT; F as REAL; H as DINT; T as TIMER; C as COUNTER). For example, N2:59 will become N002.
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 aliases. Some characters cannot be used in tag names. These aliases will be renamed.
Here are four options for remapping the I/O:
NONE: I/O addresses stay at their I or O array address
DHRIO: I/O addresses will be remapped to a DHRIO module. You will need to provide the I/O scan list for each DHRIO channel.
CNB: I/O addresses will be remapped to a 1771-ACN over ControlNet (1756-CNB). You will need to provide the ControlNet node configuration per adapter.
1756: I/O addresses will be remapped to an equivalent 1756 IO module. Select this option if you are using the 1492 I/O Wiring Conversion Kit (PLC 1771 to ControlLogix 1756).
Stored procedures (1775-GA programs) will be copied into Structured Text Routines but not converted. If you would like us to convert these programs 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
If your program is using file indirection (e.g. PFIL:4) you will be contacted by one of our engineers to discuss possible conversion options.
We guarantee that your program will be converted correctly. (no fine print)
