Configurator
Program blocks are stored in the library without I/Os. Use the auto-create and auto-connect functions to create I/Os and/or to connect them to the interface blocks, e.g., R_A, CMD_B. Alternatively, take the I/Os from the folder containing the predefined I/Os in the library and/or from the plant and connect them to the interface blocks.
Controls a multistate enable output (command) that is sent to the heat pump control unit.
This program block can be used in a program block for heat pumps (for heating only or based on a chiller) to control the outputs that are read by the control unit of the corresponding heat pump.
This program block has the following optional functions:
Option: Defrost state (1xBI)
Reads the signal for defrost state from the heat pump control unit.
Option: Fault (1xBI)
Reads the fault signal from the heat pump control unit and generates an alarm.
Option: Feedback (2xBI)
Reads the feedback signals from the heat pump control unit and indicates if the compressor is running and at what stage.
Option: Heating/cooling mode (1xBO)
Sends a command for heating or cooling to the heat pump control unit.
Option: Present power (1xAI)
Reads the signal for the present power from the heat pump control unit.
