4.1.2 Setting the Number of Monitor Points
The # of Monitors field sets the number of monitor points that will be shown in the MCT runtime application.
Up to 15 monitor points can be configured. Note that the thermocouple and analog input monitor modules
provide up to 8 inputs each, while the RTD type provides up to 6 inputs. If the CM version used supports using
the second input of the loop controls as monitor points, they may also be assigned as a monitor point.
Once the number of monitor points is set, the monitor configuration of the MCT must be set so that the proper
input assignment, units, decimal point and input ranges are used for each point. See section 4.3 Monitor Setup
for information on configuring each monitor point.
4.1.3 Setting the Number of System Events
The # of Events field sets the number of system events that will be provided in the MCT runtime application
under Manual Operation and the Overview screen. The system events are soft switches which can be assigned
to the different digital outputs configured in the system. When the event is turned on, any digital outputs
assigned to the event will be activated. This allows equipment to be turned on and off directly through the MCT
which also allows for the automatic and timed starting and stopping of equipment with the use of automatic
programs.
The maximum number of system events available is 32, one for each digital output available. Outputs can be
assigned to events specifically by the OEM in the configurator or outputs can be assigned to events in the
runtime application under the Offline\Setup\IO menu. However, in the runtime application, if a digital output is
assigned as a system event on the digital output screen, it will be assigned to the corresponding system event
only. For example, digital output 4 will be assigned to system event 4; digital output 14 to system event 14, etc.
The outputs cannot be assigned to specific events; this can only be done in the configurator.
See section 4.4 Event Setup for information on how to assign digital outputs to different system events.
4.1.4 Setting the Number of Loop/Monitor Alarms
The # of Alarms field sets the number of loop/monitor alarms that will be accessible under the MCT runtime
application Setup menu. The alarms provide various alarming and output control functions for indicating out-
of-tolerance conditions for the various loop and monitors configured in the system. The MCT-CM provides up
to 30 loop/monitor alarms.
If the maximum number of alarms is set to zero, the Alarms menu selection under the Setup menu in the runtime
application will not be accessible. This provides the OEM with a means of protecting the alarm settings from
accidental changes that may occur if the end user accesses them. It also provides a means for offering the
end user alarms that they can set up for their own use, while hiding alarms specifically configured for proper
system operation that the user is not to have access to.
The
# of Alarms for User SP Access field sets the number of loop/monitor alarms that the user has set point
access to from the Overview screen. This allows the user to have quick, easy access to adjust alarm set points
without having to access the alarm settings screen. It also allows the OEM to disable access to alarm settings,
but still allow the user to adjust an alarm set point without affecting the type or operation of the alarm.
4.1.4.1 Protected Loop/Monitor Alarms Example
Two alarms are to be provided for the end user while 10 alarms are required for use specifically by the OEM so
they are not to be altered. In order to set up the OEM alarms,
the ‘# of Alarms’ field must first be set to 12. This
allows all 12 alarms to be accessed from the Setup menu in the runtime application. The OEM can then set up
alarms 3 - 12 while leaving 1 and 2 available for the end user.
