The following parameters are used to set the "Object lock input” function:
Parameters of the “functions, objects” parameter card
Object lock input
Lock first channel input object
Lock second channel input object
Parameter | Settings |
|---|---|
Object lock input Lock first channel input object Lock second channel input object | disable enable |
Function:
If this parameter is set to "enable", the input of the channel can be disabled or enabled via a communication object.
If an input is inhibited (inhibit object = 1), neither signal changes at this input are transmitted nor the signal state are sent.
Other parameters:
If "enable” is selected, the parameters "Invert lock control” and "Value of locking object after bus voltage recovery” also appear.
Availability: "Object lock input” parameter
The "Object lock input” parameter is displayed when the following configuration has been made:
- Parameter "Function channels A + B” on the "device settings” parameter card
- Setting: “Single"
Availability: Parameters "Lock first channel input object” and "Lock second channel input object"
The parameters "Lock first channel input object” and "Lock second channel input object" are displayed if the following configuration has been made:
- Parameter "Function channels A + B” on the "device settings” parameter card
- Setting: “Pairwise”

Invert lock control
Invert lock input of first channel input
Invert lock input of second channel input
Parameter | Settings |
|---|---|
Invert lock control Invert lock input of first channel input Invert lock input of second channel input | No Yes |
Function:
This parameter is used to set whether the input of the push-button or the inputs of the push-button pair can be locked by receiving “logical 0” at the lock object.
Availability: "Invert lock control” parameter
The "Invert lock control” parameter is displayed when the following configurations have been made:
- Parameter "Function channels A + B” on the "device settings” parameter card
- Setting: “Single”
- Parameter "Object lock input” on the “functions, objects” parameter card
- Setting: “enable”
Availability: "Invert lock input of first channel input” parameter
The "Invert lock input of first channel input” parameter is displayed when the following configurations have been made:
- Parameter "Function channels A + B” on the "device settings” parameter card
- Setting: “Pairwise”
- Parameter "Lock first channel input object” on the “functions, objects” parameter card
- Setting: “enable”
Availability: “Invert lock input of second channel input” parameter
The “Invert lock input of second channel input” parameter is displayed if the following configurations have been made:
- Parameter "Function channels A + B” on the "device settings” parameter card
- Setting: “Pairwise”
- Parameter “Lock second channel input object” on the “functions, objects” parameter card
- Setting: “enable”
More information:
Value of locking object after bus voltage recovery
Lock object first channel input on bus voltage recovery
Lock object second channel input on bus voltage recovery
Parameter | Settings |
|---|---|
Value of locking object after bus voltage recovery Lock object first channel input on bus voltage recovery Lock object second channel input on bus voltage recovery | Off On Deactivated Last value Query via bus |
Function:
This parameter is used to set the value of the lock object or the lock after bus voltage failure and recovery.
The following settings are possible:
- Off:
If the parameter is set to "Off", the lock object contains the value "off” after bus voltage recovery. - On:
If the parameter is set to "On", the lock object contains the value "on” after bus voltage recovery. - Deactivated
If the parameter is set to "Deactivated", the channel lock (regardless of the value of the lock object) is disabled for this channel after bus voltage recovery.
The lock is inactive until a new specification via the communication object switches the lock on or off. - Last value
If the parameter is set to "Last value", the lock of the channel (regardless of the value of the lock object) contains the last stored value after bus voltage recovery.
If an inversion has been configured, it is not taken into account with this setting. - Query via bus
If the parameter is set to "Query via bus", the lock of the channel (independent of the value of the lock object) is queried via the bus after bus voltage recovery via "ValueRead."
If there is no response, the channel lock (regardless of the value of the lock object) is set to the last value before bus voltage failure.
If an inversion has been configured, it is not taken into account with this setting.

- Setting: “Pairwise”
- Parameter "Lock first channel input object” on the “functions, objects” parameter card
- Setting: “enable”
Availability: "Lock object second channel input on bus voltage recovery” parameter
The “Lock object second channel input on bus voltage recovery” parameter is displayed if the following configurations have been made:
