• At this moment I am working on Dimat v2
• I am about 60% done
• WPF based
• Source code will probably not be open source
• Planned features for v2 include: PLC system functions, error reading, writing variables into PLC, notes and more

S7 Diagnostic & maintenance tool

S7 Dimat is a simple software for reading Siemens PLC variables. It works almost the same way as VAT table inside Simatic manager. It uses ethernet communication, so reading from only Profibus devices is impossible. I have used Sharp7 for communication.

So not PLC people can watch variables from PLC and NOT damage any machines. Mainly industrial maintenance teams.

At this moment you can read I,Q,M,DB memory.

Simatic S7-300, S7-400, S7-1200, S7-1500

The same way you would inside Simatic manager VAT.
