Control of guard locking
From MGB version V2.36.4, the factory setting ensures that control is possible only from the safe control area.
By changing the parameters in the configuration tool of your control system, it can be set whether bit
O 16
(in the safe
data block for the MGB locking module) is evaluated as well.
Important!
The following applies to MGB-L2:
Control of the guard locking via the safe control area does not provide increased safety, as the de-
vice-internal control of the guard locking is only of single-channel design.
Important!
The following functions depend on the MGB version, the version of the GSD file and the settings made
there.
Compare the specified versions with those on your device and in your GSD file. The version number
of your MGB can be found on the type label (format: VX.XX.X).

What must be observed?
Guard locking can be controlled from the non-safe control area. The combination with the more up-to-date GSD file allows
a parameter to specify which bits are to be used for control. However, the device does not support this function. In other
words, the setting in your configuration software remains ineffective.
