Configuring the MCT-MC - 37 - FDC MCT-MC
With the Normal mode selection, the loop control will continue operation according to the last command given.
When power is first applied to the loop control, its outputs will activate immediately according to the last
commands given prior to power loss.
With the
Safety mode selection, all loop control outputs will be turned off in the event of a loss in
communications with the MC display that exceeds 60 seconds. Since the MC display provides the means for
control and monitor of loop operation, this insures that any devices connected to the loop control outputs can
be shut down/turned off until corrections can be made to restore communications.
It also insures that when power is first applied, the loop control outputs will not activate until proper
communication is established with the MC display. This prevents any devices connected to the loop control
outputs from being activated until the runtime application has started to provide the user with access to the
system.
4.3.33 Monitor Only Mode
The Monitor Only Mode selection can be used to turn a control loop into a “monitor only” device, i.e., hide the
loop set point and percentage of output in the MC runtime and only display the input value. This provides an
easy method for adding another input to the system for monitoring the value of a process, while also providing
additional outputs that could be used as events, sensor power supply, etc.
