S6_PVEA_CI_CANopen Function Block
Use the S6_PVEA_CI_CANopen function block to control the S6_PVEA_CI actuator for Danfoss PVC valves.
The function block contains CAN Rx symbols that receive emergency messages. The filters are set to receive the messages from the specified NodeId.
Functional and safety interlocks are not handled in this function block.
Input data types must exactly match the indicated type for a successful compile. Hand operation mode is not available on all S6_PVEA-CIs.
