Mike, I have now exact the same system like you have
It works when you increase the response time (10s). It was possible to send SMS with sensor information of ProfiLux 1 and 2.
The problem is that you have a very "extreme" system regarding communication:
- Both ProfiLux communicate with each other
- View 1 speaks with ProfiLux 1, View 2 with ProfiLux 2
- PC communicates to both over LAN and RS485
- and on top of this: SMS-modul talks to both ProfiLux at once
-> too much communication traffic causes delays in responses
I hope it works for you with longer response times, you will get better results when the PC is not connected during the SMS module tries to send a SMS.
For the future I try to increase the communication speed with the next firmware.
Displayed time in ProfiLuxControl: I had not time to check this today, maybe tomorrow. But don't worry, the internal time in the SMS-module is correct.
