I'm setting up a network variable communication via Ethernet, but looks like that the ifm PLC is not able to read the packages sent from another controller. Sometimes looks that the ifm PLC reads the first package, but only that.
To make it simple I have prepared a workbench with a 3S Cosdesys Control Win project that runs on my laptop and then I have set the Network variable with a different UDP port (1203). On PLC side I've imported the *.gvl file and with ethernet sniffer I can see that Control Win application send data but it is not reed from PLC.
I try to resume with a table the configuration used:
Control Win PC side CR721S PLC side
NVL TX UDP port 1203 NVL RX with *.gvl file imported (The PLC doesn't read variables)
NVL RX made with *.gvl file imported NVL TX UDP port 1202 (this part of the test WORKS!!)
I hope someones have some good advices.
