2. Correct use
The bus module MBM-EC-..-MLI-… (EtherCAT) is operated as an IO device on EtherCAT (FSoE). The bus module MBM com-
municates with the modules/submodules connected and evaluates all relevant information. It processes these data and then
transmits them on the bus connected to a control system.
Before the device is used, a risk assessment must be performed on the machine, e.g. in accordance with the following
standards:
ÌENISO13849-1
ÌENISO12100
ÌENIEC62061
Correct use includes observing the relevant requirements for installation and operation, particularly based on the following
standards:
ÌENISO13849-1
ÌENISO14119
ÌEN60204-1
The bus module MBM is allowed to be combined only with suitable modules that have an MLI interface. You will nd more
detailed information on compatibility in the operating instructions for the related MLI device. See also Table 1: Combination
options for modules with MLI technology. A maximum of 18 modules or submodules can be operated on one bus module MBM.
On the unauthorized modication of system components, EUCHNER provides no warranty for function.
The customer is responsible for the safe overall function, especially for the safe integration into the FSoE environment.
Important!
ÌThe user is responsible for the proper integration of the device into a safe overall system. For this
purpose, the overall system must be validated, e.g. in accordance with ENISO13849-2.
ÌCorrect use requires observing the permissible operating parameters (see chapter 14. Technical
data on page 56).
ÌIf a data sheet is included with the product, the information on the data sheet applies.

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)
ÌSafety function:
- If guard locking is released, safety bit LM_I_UK (ÜK) = 0 (monitoring of the locking element).
- When the guard is open, safety bit LM_I_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)).

Control of guard locking (safety bit LM_FO_CL)
ÌSafety 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 PFHDsys. and by the external control (e.g. safe
PLC).

3.5. Determining safety characteristics of the overall system
The corresponding reliability values must be determined for each safety function in the overall system. Proceed as follows:
1. Refer to the data sheets or operating instructions for the system components containing the function for information on
the reliability values for the related safety function.
2. Refer to the reliability value of the bus module MBM for the evaluation and forwarding of safety data.
3. Add together the values to a resulting reliability value PFHD, Sys
