Allocations to Slave Units Section 5-2
Note 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 including Repeater Units.
Example: In this example, operation is considered normal when all registered
Slave Units are participating, there are no communications errors at any reg-
istered Slave Units, and remote I/O communications are operating.

(all registered Slave Units participating), and bit
7 (remote I/O communications operating).
