Product Description:
The interface for primary controller functions (external Advanced Control software package)
provides primary controller functions, which run on an external PC as an OPC client, the option
of using the control from the controller function block and specifying the setpoint or manipulated
variable from a remote location. This procedure is called program mode.
You can use the feature bit Enabling program mode (Page 158) to specify whether or not the
controller block is intended for program mode.
Program mode requires an enable signal (input parameter AdvCoEn = 1) from a central
control block. If this enable signal goes from 1 to 0, for example, due to errors in the OPC
communication, the controller block switches to manual mode if it is in program mode with
manipulated variable specification or to automatic mode if it is in program mode with setpoint
specification.
