The Error Checking Alarm Process is an excellent tool for discovering problems with data collection and
issues with timing.
364
Often, this process is used only during the development of a complex configuration
to work out errors within the configuration.
3.13. Timed Event Process
Inputs: 4 Digital output channel (0 or 18 – 23)
5 Timed event on interval (xxx:xx:xx)
6 Timed event on duration (xxx:xx:xx)
7 Start of first event (xx/xx/xx xx:xx:xx)
Outputs: 1 Boolean state (0 = off, 1 = on)
E1 Process error code
Assumptions: Inputs 2 through 4 are entered and displayed as time values or as date &
time, but are stored internally and in configuration files as seconds after
midnight, 1/1/1970
The Timed Event Process is used to control the state of a data output and optional digital output on a
regularly timed basis. It operates similarly to the digital output that is controlled from the Digital Control
Menu,
365
but can be used to directly affect other Process Records by using its data output as an input to
other Process Records.
Line Items #5, #6, and #7 operate in essentially the same manner as Line Items #1, #2, and #3 of the
Digital Control Menu.
366
The beginning of the first Event-on Interval, defined by Line Item #5, is set by
Line Item #7, the Start of the first event. The duration of the Event-on Interval is set by Line Item #6.
During the Event-on Interval, data output #1 is set to one and the digital output channel specified in Line
Item #4 will be turned on if one is specified. Otherwise, data output #1 is set to zero and the digital
output channel is kept off if one is specified.
More than one Timed Event Process can be created in a single configuration and each one can control a
different digital output channel.
Coastal Environmental Systems does NOT recommend configuring more
than one Process Record to control the same digital output channel.
3.14. One-shot Daily Timed Event Process
Inputs: 4 When Timed Even Occurs (seconds after midnight)
5 Timed event on duration (seconds)
6 Digital Output Channel
Outputs: 1 Boolean state (0 = off, 1 = on)
E1 Process error code
Assumptions: Inputs 1 and 2 are entered as data inputs. Constants can be used. Their
values are in seconds after midnight of the same day
