SafetyExt_AC500_V22.lib library includes the following POUs:

• System commands

  • SF_E_ERR_LED_SET (Setting E-ERR LED state (ON or OFF))

  • SF_MAX_POWER_DIP_SET (Setting the maximum number of restarts after power dip in the safety CPU)

  • SF_WDOG_TIME_SET (Setting the maximum allowed cycle time of the safety CPU)

  • SF_APPL_MEASURE_BEGIN (This function defines the start point of time profiling)

  • SF_APPL_MEASURE_END (This function defines the end point of time profiling)

• System information

  • SF_MAX_POWER_DIP_GET (Getting the current number of restarts after power dip in the safety CPU)

  • SF_SAFETY_MODE (Reading out if the safety CPU is in DEBUG or SAFETY mode)

  • SF_SM5XX_OWN_ADR (Getting the value of the hardware switch address on the safety CPU)

  • SF_RTS_INFO (It provides the firmware version of the safety CPU. The version is a binary coded decimal, e.g., 16#10 means version 1.0)

• Data storage

  • SF_FLASH_DEL (This function block deletes a data segment in the flash memory. All data in this data segment will be deleted.)

  • SF_FLASH_READ (The function block reads a data set from a data segment of the flash memory and stores the read data set beginning at the start flag defined by the safety CPU.)

  • SF_FLASH_WRITE (The function block writes data to a data segment in the flash memory.)

• Acyclic non-safe data exchange

  • SF_DPRAM_PM5XX_S_REC (Receiving data from non-safety CPU)

  • SF_DPRAM_PM5XX_S_SEND (Sending data to non-safety CPU)
