Hi, I would like to check with you regarding S7-1200 PLC & Siwarex. We had faced a problem at site while testing yesterday, 7 December 2017. The details are as below: The PLC went into STOP mode & the Siwarex reading was not updated at the touchscreen & we got some details as attached & described below. There was error on the PLC (error LED was blinking, upon checking the we found that there is new I/O access error during process image update). Please see attached photo. We tried to put the PLC into RUN mode again but the error light was still blinking. We had checked the LED for communication between the PLC & Siwarex (the communication LED was all OK). We had then proceeded to do power cycle & immediately after the power cycle the Siwarex reading was updated. Please advise on what could have caused this to happen & if there is any solutions for this type of issues. Thank you.
