CONTROLLER CONNECTIONS FOR THE DXMR110-8K
4. Controller Connections for the DXMR110-8K
To connect IO-Link devices on machines in industrial environments, an M12 quick-disconnect connection is typically used. The pin assignment
according to IEC 60974-5 is the following:
• Pin 1: 24 V DC
• Pin 2: Switching Digital I/O (PNP only)
• Pin 3: 0 V
• Pin 4: Switching Digital I/O (NPN, PNP, or Push-Pull) and IO-link Communication Line
Figure 1: IO-Link pin assignments
One male M12 connection provides common power and ground to all M12 IO-Link ports. Two100 Mbps Ethernet ports (female) use an M12
D-coded Ethernet connection.
• Modbus/TCP
• EtherNet/IP
• PROFINET
Eight IO-Link controller connections using female M12 connectors.
• Separate IO-Link control and programmability for each connection point
• Configurable SIO mode on Input 1 and Input 2 of each IO-Link port
The DXMR110-8K IO-Link Master has eight Class A ports. Pin 2 on these is an additional discrete IO channel. For specific pinout connections,
see Wiring for the DXMR110-8K on page 6.
For more information on the device registers and port settings of the DXMR110-8K IO-Link Master, refer to the DXMR110-8K IO-Link Master
IO-Link Master Device Register Map (p/n 233478).
4.1. Status Indicators for the DXMR110-8K
The DXMR110-8K 8-Port IO-Link Hub has two LED indicators for pin 2 and pin 4 for each IO-link port to provide indication visibility. There is also
an additional amber LED indicator to indicate power to the IO-link master.
4.2. Ethernet
Before applying power to the DXMR110-8K, verify the Ethernet cable is connected.
