Modernizing Extinct Process Controls
This utility converts (migrates, translates) Allen-Bradley (AB) PLC2 (1772) programs that were created with the 6200-PLC2 programming software to Studio 5000, in other words PLC2 to ControlLogix. This conversion is a direct translation into ControlLogix (1756). It is NOT a double hop (PLC2 to PLC5 to ControlLogix (CLx)).
The data table is converted to a single dimentional array (tag name M) as type INT. 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 M.15. New tags will be created for timers, counters, and control. For example, timer address 040 will become T0040 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 aliases. Some characters cannot be used in tag names. These aliases will be renamed.
Instruction Comment will be used if no Address Comment is found.
Here are three options for remapping the I/O:
NONE: I/O addresses stay at their M array address
DHRIO: I/O addresses will be remapped to a DHRIO module with 1771-ASB as a full rack. Local I/O will need to have a 1771-ASB added.
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).
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
We guarantee that your program will be converted correctly. (no fine print)
