What is the maximum amount of data that can be exchanged between two modules via the ACD channel?
Answer:
Each machine module in the application template has the structure MACD_sc[module name]. Using the MACD variable with the data type of this structure, each machine module can exchange data bidirectionally with its higher-level machine module (parent module). This mechanism is called the ACD channel.
A maximum of 4096 bytes can be exchanged between two modules, i.e, the size of the structure MACD_sc[module name]may not exceed 4096 bytes.
If the limit is exceeded, the application template reports a system error at runtime and the PLC application is not processed. A corresponding error message appears in the logbook.
