Our Systems Engineering team have extensive working experience of every significant PLC product. This knowledge allows us to work confidently with each client's existing PLCs , in addition to installing completely new systems.

We can program complex sequences using Graph7 (see 1st image for details). Graph7 is one of the most useful productivity tools you can imagine. Programming sequences is very simple and clear. Troubleshooting problems on your sequential process is more effective for both the programming engineers and the electrical maintenance people. Process flow charts can be quickly converted into Graph7 language (because a Graph7 program is a flow Chart).


Some of the software we use to program PLC are:


Siemens S7-300 and S7-400 : Step7 with the add-on packages for Sequential Function Chart, PDiag (for real time diagnostics), Teleservice, PID self tuner, PLC SIM (For offline program simulation), Proagent, SCL, Hi-Graph.
