setup, the output control functions of each device can be changed, so any equipment being controlled by the
outputs should be placed in an “off” state, so that any modifications to output functions will not cause an unsafe
condition or damage to equipment.
IMPORTANT: Once all configuration settings are made, you mus
t select “Exit” from the File menu to exit the
Configurator prior to cycling power to the MCTB. All configuration files are written upon exiting
the Configurator. Do not cycle power prior to exiting the Configurator or settings will be lost
and the MCTB will not operate properly once the runtime application starts.
Upon exiting the Configurator application and cycling power to the MCTB, the runtime
application will be automatically started on the next boot sequence.
4.1 Control Setup
The Control Setup screen is accessed from the Setup menu. It allows the user or OEM to select the control
type, and set the number of soft alarms, monitor points and math/logic equations.
The
Control Type drop down menu is used to define the mode of operation for the MCTB. The number of B42
process loop boards and L41 limit control (if required) are set automatically and dependent upon the control
type selected. The selections include:
Single Loop When single loop is selected, the MCTB will be configured as a single loop
controller. A B42 process loop control must be attached and set to a
communications address of 1 for proper operation.
Single Loop + Limit When single loop + limit is selected, the MCTB will be configured as a single loop
controller with limit. A B42 process loop control must be attached and set to a
communications address of 1 and an L41 limit control must be attached and set
to a communication address of 2 for proper operation.
Dual Loop When dual loop is selected, the MCTB will be configured as a dual loop controller.
Two B42 process loop controls must be attached and set for communications
addresses of 1 and 2 for proper operation.
Dual Loop + Limit When dual loop + limit is selected, the MCTB will be configured as a dual loop
controller with limit. Two B42 process loop controls must be attached and set for
communications addresses of 1 and 2 as well as an L41 set for a communications
address of 3 for proper operation.
