(remove this paragraph once the translation is finished) Variant "Read" a) Read product data (basis product ID) Variable Data type Description Direction Read* BOOL This variable sets PLC when new data is available and PLC sets it back to FALSE From PLC to MES Read* BOOL This variable describes MES with TRUE, if the data was stored in the database. MES resets it to FALSE From MES to PLC Product ID* STRING The generated database GUID is passed from PLC to MES, so that the measured values can be assigned faster From PLC to MES Product Code* STRING The generated product code is provided by MES to PLC From MES to PLC Product* STRING The product is provided by MES to the PLC From MES to PLC Measured value 1..N miscellaneous The measured values or states of the produced part can be evaluated by the PLC in various data formats From MES to PLC Section 1: {Product ID} is set by PLC at least 300ms before {Read}. Section 2: {Read} is set by PLC Section 3: {product code} is set by MES {Product} is set by MES {measured values 1..N} are optionally set by MES Section 4: {Read} is set by MES. Section 5: {Read} is reset by PLC (Reason: rising edge {Read}). {Product ID} is reset by PLC (Reason: rising edge {Read}). Section 6: {Read} is reset by MES (Reason: falling edge of {Read}) {Product code} is reset by MES (Reason: falling edge of {Read}) {Product} is reset by MES (Reason: falling edge of {Read}) {Measured values 1..N } are reset by MES (Reason: falling edge of {Read})
