![]() Moreover, you can change those INITIAL VALUES in the DBs where the parameters are stored. It is very important in a project to have a documentation of the "as-left parameters" so as when there is a PLC failure or a program corruption, it is easier to re-input those values and have the plant running again. The values that the PLC is reading after the restart, were the INITIAL VALUES configured in the DBs of the project. ![]() I believe that those values were only temporary and were wiped out after the Memory reset. If that is the case, since you did an MRES, you can no longer retrieve the parameters you have manually input through the HMI. The problem is that when we turned power off for cleaning and turn on again all parameters on panel erase just # appears to solve this problem we do MERS for PLC but the parameters return to default so we need to review all parameters again we thought the battery of PLC is expired and we changed it but the problem still is there battery inside simatic panel need to change? if no can any expert help me to find the reason of this problemÄo you mean that the communication is restored but the values are not the ones you have input before? I have problem in machine that have simatic touch panel connected to S7-313 PLC ![]()
