Function Blocks for Acyclic Data Exchange CM574-RS/AC500 \ CPU

Unlike the cyclic data exchange via input/output signals, the acyclic data exchange has to be programmed in the user program.

The acyclic data exchange is used mainly for transmitting commands for own protocols. For example, the entire data exchange between the AC500 CPU and a CM574-RCOM occurs via these blocks.

The following blocks are available:

Description	CM574-RS	AC500 CPU
Library	SysIntExt_AC500_V13.lib	SysInt_AC500_V10.lib
Transmission from the CM574 to the AC500 CPU or reception in the AC500 CPU from the Communication Module	DPRAM_PM5XX_SEND: DPRAM_PM5XX_SEND	DPRAM_CM5XX_SEND: DPRAM_CM5XX_SEND
Reception in the CM574 from the AC500 CPU or transmission from the AC500 CPU to the Communication Module	DPRAM_PM5XX_REC: DPRAM_PM5XX_REC	DPRAM_CM5XX_REC: DPRAM_CM5XX_REC
