OVERVIEW
MSC is a modular safety system and comprises a base unit (MSC-CB), which can
be configured using the graphic user interface in EUCHNER Safety Designer, and
various expansion modules that can be connected to MSC-CB via the proprietary
MSCB bus.
The base unit MSC-CB, which can also be used as a standalone device, has 8 safe-
ty inputs and 2 separate, programmable dual-channel outputs.
The following expansion modules are available: FI8FO2 with inputs and outputs,
FI8, FM4, FI16, SPM0, SPM1 and SPM2 with only inputs, AC-FO2 and AC-FO4 with
only outputs as well as AZ-FO4 and AZ-FO4O8 with positively driven safety relays.
Expansion modules for connection to the commonest industrial fieldbus systems for
diagnostics are also available: CE-PR (PROFIBUS), CE-CO (CanOpen), CE-DN (De-
viceNet), CE-EI (ETHERNET/IP), CE-EI2 (ETHERNET/IP-2PORT), CE-PN (Profinet), CE-
EC (ETHERCAT), CE-MR (Modbus RTU), CE-MT (Modbus/TCP).
MSC makes it possible to monitor the following safety sensors and command
switches:
Optoelectronic sensors (safety light curtains, scanners, safety-light barriers), me-
chanical switches, safety mats, emergency stop buttons, two-hand controls, which
are all managed via one single, flexible device that can be expanded.
The system is only allowed to comprise a single base unit MSC-CB and a maximum
of 14 electronic expansion modules, of which not more than four are allowed to
be of the same type.
With 14 expansion modules the system can have up to 128 inputs, 16 dual-
channel safety outputs and 28 status outputs. The communication between the
base unit (MASTER) and expansion modules (SLAVES) is via the MSCB 5-way bus
(proprietary bus from EUCHNER) that is on the rear side of every module.
In addition, 8 inputs and 16 outputs are available and can be controlled using
sensors (via the fieldbus).
Using the MSC expansion modules FI8, FI16 and FM4, the number of inputs in the
system can be increased such that more external devices can be connected. FM4
also provides 8 outputs of type OUT_TEST.
With the expansion modules AC-FO2 and AC-FO4, the system has 2 or 4 OSSD
pairs to control devices that are connected downstream of the MSC system.
FI8FO2 has 8 inputs and 2 OSSD outputs.
The expansion modules in the CE series make it possible to connect the common-
est industrial fieldbus systems for diagnostics and data transmission. CE-EI, CE-
EI2, CE-PN, CE-MT and CE-EC also have an Ethernet connection. CE-US makes it
possible to connect devices with a USB port.
CE-CI1, CE-CI2 are modules in the MSC family that make it possible to connect
MSC-CB to expansion modules further away (<50m). Two CE-CI modules are con-
nected at the required distance using a screened cable (can be ordered from
EUCHNER or as per the table for the technical cable data).
