If a local station detects an error, the bit corresponding to
the station number becomes "1".
Example: When station 6 and 12 detect an error, bits 5
and 11 in SD1216 become "1", and when
SD1216 is monitored, its value is "2080
(820

Bit
Device
number
If a local station acting as the master station of tier three
detects a parameter error or a remote station contains an
invalid I/O assignment, the bit corresponding to the
station number becomes "1".
Example: When local station 5 and remote I/O station
14 detect an error, bits 4 and 13 in SD1220
become "1" , and when SD1220 is monitored,
its value is "8208 (2010
