info

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.

Function

Controls an intelligent valve that is integrated over BACnet or Modbus.

This program block contains optional elements that read different pieces of information from intelligent valve.

Option: Flow monitoring

Reads the present volume flow from the intelligent valve.

Generates an alarm if a signal for setpoint relative is above a specific value, e.g., 4 %, and there is no flow.

The following option can also be used.

Option: Kick function

Prevents standstill damage by generating a pulse that opens the valve at a configured time with a defined pulse length after a minimum off time has elapsed.

info

This is configured in the program.
