Safety IO State
1A05h
UInt8
Bit 0
Safe Input 1
Set if channel a and b of the safe input 1 on X49a/b are active. Otherwise
cleared. This status bit can also be accessed over UPID 1A50h.
Bit 1
Safe Input 2
Set if channel a and b of the safe input 2 on X49a/b are active. Otherwise
cleared. This status bit can also be accessed over UPID 1A51h.
Bit 2
Safe Output
Set, of the safe digital output on X49a/b is active. Otherwise cleared. This
status bit can also be accessed over UPID 1A52h.
Bit 3
