Communication error
A communication error is signalled only if a suitable communication mode is selected (Pr06 ≥ 2), and the
communication alarm is active (Pa01 = 1). Under these conditions, the driver expects the controller to periodically
refresh the Enable valve command (EnaV).
If the refresh does not happen for more than half the time set in Communication alarm delay (Pa02), a warning is
given. If the refresh does not happen for more than the time set in Communication alarm delay (Pa02), the
communication is considered lost and communication alarm is set.
Management of this alarm depends on the mode selected. If Pr06 = 2÷5, a communication alarm state will cause the
valve to be forced to the position determined by Communication error position (Pr48), and will then enter the
Communication alarm (5) until the positioning process has completed and the communication start again. If Pr06 =
6÷9, a communication alarm status will place the valve into standalone mode, and DI1 enable the valve.
When the communication alarm is cleared, the valve will automatically return to the online mode.
