SIWREX MS does NOT work reliable!

zani2 Posts: 15 Rating: (1)	Hello again I did a test.I deleted the software routines for first SIWAREX-MS module in the program(CPU226 does not scan the siwarex at this state,RUN LED flashes), and CPU226 only reads the second SIWREX-MS(that works nice before) ,The problem is tranfered to second SIWAEX-MS! its RUN LED flashes after several hours. Why problem transfered to second siwarex-ms when the first siwarex-ms was disabled in software of CPU226? Its seems always the first SIWAREX-MS in the PLC peripherals chain will fail after hours of good operation,with a power recycling the system comeback to normal again. I tested the wiring it is OK. No wrong inwiring.

One sollution could be with memory Cartridge that could be loading an old program after a failureOr maybe could be the PLC cycle time.
