FDC MCT-MC - 36 - Configuring the MCT-MC
The
Continue automated program from last SP selection will resume the program from where it left off with
the last set point set by the program at the time of power failure.
The
Continue automated program from PV selection will resume the program using the current process value
at the time power is restored as the set point.
The
Static mode selection will terminate the automated program and return the loop control to the single set
point mode of operation using the previous set point value prior to starting the automatic program. In addition,
any outputs configured as events will also be returned to their previous on/off prior to starting the program.
NOTE: The MC does not support the P41/B42 “Off Mode” recovery option. This selection is not available
through the MC configuration.
4.3.32 Communication Mode
The Communication Mode selection is used to specify how the loop control responds to a loss of
communications with the MC display. The communication mode selections are mutually exclusive, i.e.,
selecting one will turn off the other. Once the desired mode has been selected, press the “Done” button to set
the communication mode for the loop control board and return to the main Loop Configuration screen.
NOTE: It is recommended that the “Safety” communication mode be used to insure all outputs are turned off
(linear outputs set to 0%) in the event of a loss of communications between the MC and the loop
control.
