This is the web edition of the original ‎⮫ AC500-S safety user manual, version 1.3.2. This web edition is provided for quick reference only. The original safety user manual must be used to meet functional safety application requirements.

On safety CPU, use the function blocks SF_DPRAM_PM5XX_S_REC and SF_DPRAM_PM5XX_S_SEND

⮫ “SF_DPRAM_PM5XX_S_REC”

⮫ “SF_DPRAM_PM5XX_S_SEND”

Transferred data is swapped

The data exchange is taken byte-by-byte which leads to a data byte swap in the target system for all data types larger than 1 byte.

This is due to the different endian systems in safety CPU and non-safety CPU.
