Hello!
I have a problem in communication between Siemens 400 PLC and x-ray for luggage examination.
I am communicating with x-ray via CP441 module, point to point and I use bsend and brcv blocks in TIA Portal.
First day when I tried to establish connection I managed to send data to x-ray (what I can see on it) but couldn't recieve and recieve block was constantly in error, showing error code 1 what means something is wrong with communication. After I restarted x-ray error was gone and I could recieve data from it.
My problems begin next time when I came to work with it and I cannot at all recieve data (I send normally), error code 1 is constant at brcv block and when I tried to restart both x-ray and PLC several times didn't help. X-ray is setup so, that when it recieves a code from me automatically sends back to me and then I see that both RxD and TxD are blinking.
Now I'm waiting for xray technicians to get a conformation from them that x-ray is functioning normally.
What is your opinion, could be something wrong on my side, because I don't have many experience with Siemens equipment and software?
