I have a question for experts with diverse experiences. Thank you for your valuable reply. I am currently using redundant CPUs from the S1500 series. The CPU, IM155-6 PN module, and SCALANCE are communicating in a ring structure. SCALANCE is communicating with about 20 G120C inverters, a Touch Panel manufactured by Proface, a QR reader manufactured by Keyence, and a vision camera manufactured by Cognex. All configurations have been completed, and the equipment is actually in operation. However, the communication connection with the IM155-6 PN module is repeatedly disconnected and reconnected every few hours. After contacting Siemens, the solution we got was as follows: 1. The CPU communication load value has been increased to 50%. 2. The watch dog time of the modules that make up the communication configuration has been increased. 3. The minimum cycle time of the CPU has been increased from 1ms to 2ms. 4. The update time of the modules that make up the communication configuration has been increased from auto to 4ms. I tried all 4 solutions, but the problem still persists. Communication is interrupted and restored every few hours. (IO Device2,3) I will attach the contents of the diagnostics buffer. Plate communication errors can be ignored. thank you
