Installation Instructions MSR241
Installing MSR241
Follow theses steps, to install the MSR241
module:
1. Set the Node Address and the Baud
rate on the module.
2. Connect the MSR241 with the safety
system MSR200 via ribbon cable.
3. Connect the relay outputs
4. Connect the DeviceNet Cable.
5. Communicate with the MSR241
module.
These steps are explained in detail in the
following procedures.

Connect the MSR241 with the safety system MSR200 via
ribbon cable
The MSR241 mount to a panel or DIN rail, which must be grounded before
installing the module.
Connect the MSR241 either to the Basic module or to an output extension
module on the right side of the MSR200 safety system via ribbon cable.
The terminator for the EDM loop is integrated in the MSR241.
Connect the relay outputs
If you want to use the relay outputs of the MSR241 connect them to your
application.
Connect the DeviceNet Cable
Refer to following information when connecting the DeviceNet wire to the
MSR241.
1. Connect the DeviceNet cable (drop line) to the unsealed DeviceNet
terminal connector.
2. Connect the terminal connector to the module. Use the side screws on
the terminal connector to fasten it to the module.
IMPORTANT
Pin Number Wire Color Abbreviation Description
1 Black V- Power return
2 Blue CAN_L Data line (CAN Low)
3 Clear Shield Between cable jacket and wire
4 White CAN_H Data line (CAN High)
5 Red V+ Positive voltage (hot)
The bus cable must be terminated with a resistor (121 Ω / +/- 1% / 0,25W).
The resistor is contacted with CAN_H and CAN_L.

Communicate with the MSR241 module
To transfer data from MSR241 to the D-Net it is required to upload the
“Electronic Data Sheet” (EDS file). This file is available for free download on
the A-B web-page: http://www.ab.com/networks/eds/ >Product Name
MSR241P
The name of the EDS file is: 0001000C00A30100.eds
The MSR241 operates as a “Group 2 only slave” device and supports UCMM.
The MSR241 is exchanged with the master through a polled, cyclic or change
of state connection.
Polled – Masters initiates communication by sending its polled I/O messages
to the MSR241 module. The module consumes the message, updates any
outputs, and produces a response. The response contains the input data.
Cyclic – allows configuration of the module as an I/O client. The module will
produce and consume its I/O cyclically at the rate configured.
Change of state – production occurs when an input changes. If no input
change occurs within the expected packet time, a heartbeat production
occurs. This heartbeat production tells the scanner module that the MSR241
is alive and ready to communicate. Consumption occurs when data changes
and the master produces new output data to the module.
The module produces 4 bytes and consumes 1 byte for outputs.
