Overview
The R45C 2-Port Converter connects to two IO-Link devices and provides access to IO-Link data and functionality via a Modbus RTU connection.
Modbus registers allow for access to both IO-Link devices and their functions:
• Process Data In
• Process Data Out
• Connected device information
• ISDU data
• Discrete I/O configuration
• IO-Link events
• Data storage
• SIO mode

Status Indicators
The R45C-2K-MQ IO-Link Master/Modbus Converter has matching RGB LED indicators on both sides for each IO-Link device port to allow for
installation needs and still provide adequate indication visibility. There is also an Amber LED indicator on both sides of the converter, which is
specific to the Modbus communication.
IO-Link Device Port 1 and Port 2 RGB LEDs
Indication Status
Off Deactivated port
Flashing Green Waiting for IO-Link device
Solid Green IO-Link device is connected
Flashing Red Validation Error
Solid Yellow Signal high in SIO-mode
Solid Blue Processor communication error
Modbus Communication Amber LED
Indication Status
Flashing Amber (4 Hz) Modbus communications are active
Solid Amber (2 seconds) to Off Modbus communications are lost after connection
Solid Amber (2 seconds) to Flashing Amber
(4 Hz)
Modbus communications momentarily lost, but then reestablished
Solid Amber Modbus communications are intermittent, or communications error
occurs more frequently once every 2 seconds
Off Modbus communications are not present
Mechanical Installation
Install the R45C 2-Port Converter to allow access for functional checks, maintenance, and service or replacement.
All mounting hardware is supplied by the user. Fasteners must be of sufficient strength to guard against breakage. Use of permanent fasteners or
locking hardware is recommended to prevent the loosening or displacement of the device. The mounting hole (4.5 mm) in the R45C 2-Port Converter
accepts M4 (#8) hardware. See the figure below to help in determining the minimum screw length.
