• The safety communication status of safety connections of the 
module stored in SA\SD1089 is stored.
• 0 is stored if not used in SA\SD1104 to SA\SD1223, or if own station.
 0H: Performing safety refresh communications
 10 to 15H: Performing safety initial communications
*2
 30H: Safety communication stopped (This value is stored when 
the safety communication error occurs and the systems are 
switched in interlock status.)
 1000H or later:For details on the values stored when an error 
occurs, refer to the list of error codes. ( Page 703 List of error 
codes)
