Issue
A custom application requires that SIGNAL be programmed to trigger a DPT block in a Network 8000 GCM four times a day every day of the year. Can this be done without manually entering four overrides via the Calendar program for every day of the year?
Environment
SIGNAL (all versions)
Cause
Customer wants to know if SIGNAL-to-GCM communications has failed at anytime during a 24 hour period.
The on-site GCM has a modem and can dial-out alarms to a pager. A DPT block has been configured with a timer such that if it's not "started", an alarm is generated. The Start command comes from SIGNAL every four hours and is reset to a Stop condition within the GCM, after the timer expires and the block has been interrogated.
Resolution
Calendar overrides can minimize the amount of time required to create a Start command several times a day, every day.
The override is given and Start/End date and time. The date field includes a "year". So, the override can apply for several years.
It can be linked to a WEEK or OSS block in the GCM and be given override commands for each day of the week.
The override event is a START and the duration is programmable in hours and minutes. Up to six events per day are possible.
Setting up a multi-year override for every day of the year and with multiple events per day will take only a few minutes to program.
