set of normally open (NO) and normally closed (NC) contacts and is capable of
switching AC and DC loads up to 3 amps. The V78 CRM-1 employs
electromechanical relays having zero current leakage and can be used to switch very
low-current loads. All relays may change state on demand via data commands or
time schedule.
Individual relay status may be presented to a host system automatically or upon
request. The relay status may be the current state or change-in-state history of a
specific relay. Data associated with the relay status which is generated by the V78
CRM-1 and sent to the host system will be referred to as a data message. Data
messages consist of the actual relay status (energized or de-energized) preceded by
the appropriate unit/module/relay number and may include a Time Tag showing the
date and time the relay status was recorded. Data messages are supplied to the host
system upon request, at a specific time, or as events occur. An event is the change-in-
state of a relay.
You have the choice of programming the V78 CRM-1 via verbose (menu-driven) or
non-verbose (dynamic) configuration mode. When using verbose configuration
mode, a series of menus will prompt you to enter the desired configuration
parameters. Non-verbose or dynamic configuration mode allows you to program
certain parameters of the V78 CRM-1 by downloading configuration. You may
review the current V78 CRM-1 configuration status from the control panel.
