Note 1: "n" depends on the communications mode as shown below when the first refresh device address in the
remote input (RX) area is 0 and the station number of the Gateway Unit is 1.
Communications mode 0 or 4: 10, Communications mode 1 or 5: C, Communications mode 2: 6, or Com-
munications mode 3: 2.
2: Bits 0, 1, and 3 output a logical OR of the status of all Slave Units other than Repeater Units; bits 4 and 5
output an OR of Repeater Unit status only; and bit 2 outputs an OR of the status of all Slave Units and
Repeater Units.
Example: In this example, operation is considered normal when all registered Slave Units are participat-
ing, there are no communications errors at any registered Slave Units, and remote I/O communications
are operating.
