Hello, i need a help with strange behaviour of CP 1243-1. Im using this CP to communicate with InTouch (HMI) and to remote connect to CPU with my STEP7 TIA-PORTAL (Professional V12 SP1). And for some time everything is working ok. (sometimes one week, sometimes one month). Then something happen (i dont know what) and i cannot connect to CPU through this CP and InTouch cannot communicate with PLC. The ethernet port on CPU is all the time without any problem (this interface is used for HMI Siemens panel). After switching off and on power supply for CPU or after downloading project to CPU through working ethernet interface (on CPU) everything is going back to fine state. Btw all the time (even if this CP isnt working) im able to ping CP and it responds. Any idea what could be the problem ? What can i test / do ? Full project in V12 SP1 TIA PORTAL is in attachment.
