BASE UNIT AND MODULE OPERATION
____________________________________________________________________________
156
energizing and de-energizing of a relay is referred to as a relay event. Up to 12
relay events may be programmed in the schedule. Once the relay event schedule
has been programmed, you may enable, disable, or delete specific relay events.
Each relay event consists of a Start Time, Duration, Interval, and Relay Number. The
Event Start Time consists of the day of the week and the hour/minute/second of the
day the initial event is to occur. The Event Duration Time is the amount of time a
specified relay will be energized and may be programmed in hours/minutes or
milliseconds. Interval is the desired time subsequent occurrences of the same event
will transpire. Interval consists of the desired day of the week and
hour/minute/second of the day. The Relay Number is the particular relay that will be
energized for a specific event.
For example, you could program a relay to activate a sprinkler system starting on the
following Monday at 5:00pm for one hour and then occurring every Monday,
Wednesday, and Friday at 5:00pm for one hour after that.
DATA MESSAGE PRESENTATION
Data message presentation varies slightly in format depending on module
configuration. Entries such as, time tag, data format, number of active channels, etc.
all change how data messages appear to a host-controller. However, all data
messages are presented in the same basic order of fields as follows:
UU:MM,CC HHH or DDDD or VV MM/DD/YY HH:MM:SS
where, UU is the M Series Unit Number
MM is the V77 ADM-1 Module Number
CC is the V77 ADM-1 Channel Number
HHH is a Hex value ranging from 000 to FFF
DDDD is a Decimal value ranging from 0 to 4095
VV is an Engineering unit ranging from -10 to +10 volts
MM is the month (if Time Tag enabled)
DD is the day (if Time Tag enabled)
YY is the year (if Time Tag enabled)
HH is the hour (if Time Tag enabled)
MM is the minute (if Time Tag enabled)
SS is the second (if Time Tag enabled)
EXAMPLE: A complete data message from an V78 CRM-1 installed as Unit 1,
Module 15 with Channels 1-8 active using Hex Data Format and having Time Tag
enabled, would appear as follows:
