General Information SAFEMASTER M
The maximum configuration of the SAFEMASTER M multi-function safety
system is as follows:
• the control unit BH 5911
• up to 3 input modules BG/BH 5913, or BG/BH 5914, BH/BH 5915
• up to 3 output modules BG 5912
• 1 diagnostic module BG 5551 for CANopen, or
• 1 diagnostic module BG 5552 for Profibus-DP
The BH 5911 controls the whole system.
The input/output modules can be used to expand the control unit in a
modular way into a multi-functional safety system.
To transmit status messages of the individual modules to a moni to ring or
control unit, one of the following diagnostic modules may be connected:
• BG 5551 for CANopen
• BH 5552 for Profibus-DP
