|^Variable ^Data type ^Description ^Direction|
|Written* |BOOL |This variable sets PLC when new data is available and PLC sets it back to FALSE |From PLC to MES|
|Written* |BOOL |This variable writes TRUE to MES when the data has been stored in the database. MES resets it to FALSE |From MES to PLC|
|Product code* |STRING |This variable allows the PLC to specify the unique embossing text to which the data refers |From PLC to MES|
|Product* |STRING |This variable allows the PLC to specify a product; e.g. the recipe name (can be static) |From PLC to MES|
|Product ID* |STRING |The generated database GUID is provided by MES to the PLC, so that further measured values can be assigned faster |From MES to PLC|
|Measured value 1..N* |miscellaneous |The measured values or states of the produced part can be specified here in various data formats |From PLC to MES|
