PLC Convert

PLC Convert is an application which can be used to convert Siemens (TI) PLC ladder logic to run on an Omron PLC. The ladder logic listing file is first loaded into PLC Convert. Then the "Build" function is run on to convert each rung to the corresponding SysWin code. Rungs can be run on a single line or in automatic mode to convert the entire program. This screen shot of PLC Convert running shows the Ladder, Code, and Symbol windows for a single line of code.

In converting the ladder logic, the program uses settings from the configuration files to determine how to convert from TI addresses to Omron Addresses, how to convert symbols, and how to abbreviate symbols. Abbreviations can be used to convert symbols which needed to be shortened in order to fit in TiSoft. Spell checking can also be done. This is not only for fixing spelling mistakes, but also to enable the programmer to automatically change symbols references which wouldn't look nice after the conversion.

Sample configuration files are listed below:

   
Address Mapping
   C1=300.00-511.15
   V1=1
   X1=0.00-29.15
   Y1=0.00-29.15
   X501=200.00-252.15
   Y501=200.00-252.15
   WX145=150
   TCC1=CNT1
   TCP1=TIM1
   STW1=256
   O/S=30
   Dummy=256.00
   50-99=DM245

   

   
Abreviations
   Registration=Reg
   Contactor=Cont
   Hydraulic=Hyd
   Temperature=Temp
   Pressure=Press
   Overload=Ovld
   Material=Matl
   Override=Ovr
   Velocity=Vel
   Computer=Comp
   Counter=Count
   Transfer=Trans

   

   
Spelling
   Crm=CRM
   Plc=PLC
   Pc=PC
   Ol=OL
   I/o=I/O
   O/s=O/S
   On / Off=On/Off
   Htr=Heater
   Enabl=Enable
   Outpt=Output
   Vac=Vacuum
   Batry=Battery
   Tmout=Timeout
   Safty=Safety
   Follo=Follow
   Modul=Module
   Brekr=Breaker
   Over Load=Overload
   Hyd=Hydraulic
   Asist=Assist
   Inp=Input

   

The PLC Convert program will convert the ladder logic either a single line at a time, or automatically convert every line. Once the program has been converted, the codes and symbols can be loaded into SysWin one by one, or as a complete program. Ladder logic, Code and Symbols can all be edited individually in this program before sending to SysWin. The PLC Convert program is available for Free download, complete with source code.
