Hello,
I have connected 43 modbus devices to a Ignition server. 25 are Analog-Digital converters and the other 18 are energy meters (Siemens PAC 3200 and Siemens PAC 2200)
All Energy meters are in the same network segment and are connected and can be accessed (firewall OK, Pingable, telnet works).
I have issue with 3 of them. Ignition does not connect to them and always states them as Disconnected and never tries to reconnect.
I have already tried to disenable/ enable them -> Immediately state Disconnected.
Restart Server/ Service -> Immediately state Disconnected.
Disabled all tags in Ignition Designer -> No change
The strange thing is that I can connect these 3 devices with another software (OpenMod Scan) on the same server and they work well and i can read data. Thus i think it must be an Ignition issue
We use Ignition 8.1.35
I also tried to connect the devices to another ignition server with 8.3.2 getting the same result as with 8.1.35.
CPU/Memory load is also very low:
Diagnostics/Logs does not show anything related to these devices.
What can be the problem?
Thanks in Advance for your help.
