Table 1: Byte 1: Logical signals
Bit Designation
(process representation)
0 Bit: End p. OPEN
1 Bit: End p. CLOSED
2 Bit: Setpoint reached
3 Bit: Not ready REMOTE
4 Bit: Running OPEN
5 Bit: Running CLOSE
6 Bit: Warnings
7 Bit: Fault
Table 2: Byte 2: Actuator signals
Bit Designation
(process representation)
0 Bit: Thermal fault

Value Description
1 For limit seating: Limit switch operated in direction OPEN
For torque seating: Torque switch and limit switch operated in direction OPEN
0 No signal
1 For limit seating: Limit switch operated in direction CLOSE
For torque seating: Torque switch and limit switch operated in direction CLOSE
0 No signal
1 The setpoint is within max. error variable (outer dead band). Is only signalled if
Modbus master has set the Fieldbus SETPOINT bit (process representation output).
0 No signal
1 Collective signal 04:
Contains the result of a disjunction (OR-operation) of all bits comprised in bytes 13
and 14 (Not ready REMOTE 1 and Not ready REMOTE 2).
The actuator cannot be operated from REMOTE.
The actuator can only be operated via the local controls.
0 In bytes 13 and 14, no signals are active (all bits are set to 0).
1 An operation command in direction OPEN is performed via fieldbus: Fieldbus OPEN
or Fieldbus SETPOINT (process representation output). This bit remains also set
during operation pauses (e.g. due to the dead time or the reversing prevention time).
0 Operation in direction OPEN via fieldbus is not executed.
1 An operation command in direction CLOSE is performed via fieldbus: Fieldbus CLOSE
or Fieldbus SETPOINT (process representation output). This bit remains also set
during operation pauses (e.g. due to the dead time or the reversing prevention time).
0 Operation in direction CLOSE via fieldbus is not executed.
1 Collective signal 02:
Contains the result of a disjunction (OR-operation) of all bits of bytes 17 to 20
(Warning 1 to Warning 4).
0 In bytes 17 and 20, no warnings are active (all bits are set to 0).
1 Collective signal 03:
Contains the result of a disjunction (OR-operation) of all bits of bytes 15 and 16 (Fault
1 and Fault 2).
The actuator cannot be operated.
0 In bytes 15 and 16, no faults are active (all bits are set to 0).
Byte 2: Actuator signals
Value Description
1 Motor protection tripped
0 No signal
1
When connecting to a 3-ph AC system and with internal 24 V DC supply of the
electronics: Phase 2 is missing.
When connecting to a 3-ph or 1-ph AC system and with external 24 V DC supply
of the electronics: One of the phases L1, L2 or L3 is missing.
0 All phases are available.
1 Selector switch is in position REMOTE.
0 Selector switch is not in position REMOTE.
1 Selector switch is in position LOCAL.
0 Selector switch is not in position LOCAL.
1 Limit switch operated in direction OPEN
0 No signal
1 Limit switch operated in direction CLOSE
0 No signal
