Holding register operation commands also change the corresponding coils for operation commands.
Operation commands which cannot be executed are rejected with ILLEGAL DATA VALUE (code 03). Operation commands
cannot be executed if a thermal fault or mains failure have occurred, or if the local controls are not set to remote, or if
commands are contradictory.
If a thermal fault or a mains failure occurs during remote operation, or if the remote operation is switched off via the selector
switch, the actuator will cancel all pending operation commands

10.2 Description of the output data

Register 1: Commands (high byte)
With the bits 0 – 2, the opera-
tion commands are transmit-
ted to the actuator. Only one of
these bits may be set at any
given time.
SETPOINT is set, the value of
the nominal position
(register 2) is used.
Bits 3 – 15 are reserved for fu-
ture extensions and must re-
main set to 0.
As soon as these bits are writ-
ten to via coil functions, the
contents of the respective
Holding Registers for the op-
eration commands will also
change.
If the Coil Remote SETPOINT
is used, the
setpoint has to be entered on
the setpoint register.

Via the process representation output, the master (controls) can control the
slave (actuator).
Functions to be used:
