Hello everybody !
I'm a new Proview user, and first of all, I want to thank all of the contributors of this wonderful application
Nevertheless, I can't fix a random modbus communication problem: I have configured a modbus TCP link to communicate with a Siemens Logo! module.
In Proview, after having set-up input and output in nodes and plant places and created a dedicated synoptic, I can start the runtime and open the synoptic. But I'm a little bit disappointed about the response time of the connection: sometimes everything go right, sometimes no. I may have missed something important, but I can't figure what
For information:
- the connection between the computer and the siemens module is direct (no switch, router, etc).
- If I use a modbus tool like qModbusMaster, no problem to write nor to read inputs / outputs.
- The Proview application runs onto a Debian v8.1.
- I have connected the digital inputs #5 and #8 to the output relay #1 (thanks to a wire => I expect a status change of these two inputs when the relay is ignited
)
- The problem occurs randomly: for example, I had no problem during the whole afternoon. I tried to shut the computer and start it again without changing anything, and the problem occurs again...
Do you have any idea ? In order to illustrate the issue, I attach a screen record of the behaviour... hope it will help.
Thank you very much for your support.
Best regards,
Raphael
