Have look at following things 1. Check the Cross Reference of Output & interlock Addresses may be used as Byte / Word / Dword in other part of programe. 2. Check if Memory Area is used may be be defined as Clock memeory in CPU Hardware Configuration

Kampf-Pasman Posts: 75 Rating: (13)	Hello SPV, we had such a problem twice. The first time was on a Soft-PLC RTX and the second time was on a S7 400. I don' remember the exact CPU type. For the SoftPlc we got a HotFix from Siemens to solve the problem. The case with with the S7-400 was solved by loading SP1 in V5.4. If you have several identical machines: 1. Are the CPU's the same, exactly the same firmware? If not swap two CPU's and check again. Are the programs also "identical"? regards Pasman There are always funny things between SIEMENS and heaven....
