Connecting code reader to fieldbus

The code reader can be connected to the following fieldbuses via the MA 2xxi modular connection units:
• CANopen: MA 235i
• EtherCAT: MA 238i
• EtherNet/IP: MA 258i
• DeviceNET: MA 255i
• PROFIBUS: MA 204i
• PROFINET: MA 248i
NOTICE
Ready-made cables are available for connecting the code reader to a modular connection unit
(see chapter 16.4 "Cables accessories").
7.7 Connecting code reader to MA 150 connection unit
The signals from the code reader are distributed in the machine decentrally via the MA 150 modular con-
nection unit. The following components can be connected to the MA 150 connection unit:
• Code reader of the DCR 200i series
• Photoelectric sensor/diffuse sensor to activate the code reader
• Voltage supply
• External illumination
• Serial communication RS 232/RS 422
