Thank you Crossbow. I´ve cheeked in the PLC program, with GX Developer, with the Entry Data Monitor from Monitor submenu of Online menu, that the X0 (WDT error) input of the A1S68AD remains set in 1, so, the hardware manual says probably a hardware malfunction. Thank you again for your answer.

Hi everybody. I have an A1SHCPU working instead of an old and damaged A1SCPU-S1. The program migration seems to be all right, but now, I have another problem. The A1S68AD module, (mounted in a A1S55B-S1 Extension Base Unit), involved in the process is not working. I´m not sure if is it damaged too or is just a configuration problem originated from de A1SCPU-S1 to A1SHCPU migration. Maybe somebody here can help me find out where the problem is? When I power the system up, the A1S68AD RUN LED turns on for half a second and then turns off again. On the other hand, if I pull out the A1S68AD module, the A1SHCPU give me error number 31 (MODULE VERIFY ERR.) and then error 41 (SP. MODULE DOWN). When I use buffer memory batch monitoring it seems to work fine too. Thank you in advance and best wishes. Esteban Fosco Cel.: 02346-15-458660 Tel.: 02345-46457
