(SPDT) relays. Each relay has a set of normally open

(NO) and a set of normally closed (NC) contacts capable

of switching AC and DC loads up to 3 amps. All relays

on the V78 CRM-1 are programmable to change state on

demand by sending commands or via time schedule.

The status of individual relays is presented as a "1" if

the relay is energized or "0" if the relay is de-energized.

The relay status can consist of buffered data

representing the history of changes in the state of a

specific relay or the current state of a specific relay.

Each "1" or "0" in the relay status is preceded by the

appropriate unit:module,relay number. The "1" or "0"

can be optionally appended with a "real time" Time Tag

showing the date and time the status was recorded.
