PLC4C was always intended to be a super small implementation of PLC4X drivers, aimed at super tiny embedded computers. For the sake of the size of these drivers, the PLC4X drivers don't have the same set of features the full blown drivers in Java and Go have. One of the features the C version is missing, is the query-optimizer, that takes care of transparently splitting up large plc4x requests into multiple smaller S7 requests. How this splitting is done, depends on the type of S7 and the corresponding PDU size. When using PLC4C you will have to manually ensure the PDU size of your PLC is not exceeded manually and you'll have to execute multiple separate requests. -- This is an automated message from the Apache Git Service.
