Operating Instructions Bus Module

MBM-PN-..-MLI-… (PROFINET)

3. Description of the safety function

The safety function of the bus module MBM comprises evaluating the safety data transmitted from the overall system (e.g.

from installed guard locking devices, emergency stop devices, enabling switches, etc.) and forwarding these data on a

bus system connected. The number of safe devices in an overall system is limited to 12. Depending on the modules and

submodules connected, the overall system can include the following safety functions:

3.1.

Safety functions in combination with an interlocking or locking module MGB2-I or

MGB2-L

The following applies to the MGB2-L…:

Monitoring of guard locking and the position of the guard

(interlocking device with guard locking according to EN ISO 14119)

Safety function:

-If guard locking is released, safety bit

LM_FI_UK

(ÜK) = 0 (monitoring of the locking element).

-When the guard is open, safety bit

LM_FI_SK

(SK) = 0 (monitoring of the position of the guard).

-Guard locking can be activated only when the bolt tongue is located in the locking module (prevention of inadvertent

locking position (faulty closure protection)).

Safety function:

-If the device is used as guard locking for personnel protection, control of guard locking must be regarded as a safety

function.

The safety level of guard locking control is determined by the system PFHD

sys.

and by the external control (e.g. safe

PLC).
