6.1.1 MD 748i-11-42/L5-2222 IO-Link Ports
The MD 748i-11-42/L5-2222 provides four IO-Link ports (depending on the model) with M12, 5-pin
female/A coded connectors.
This table provides signal information for the IO-Link connectors.

2 DI
3 L-
4 C/Q
5 N/A
The standard SDCI (IO-Link) transmission rates are supported:
 COM1 4.8Kbps
 COM2 38.4Kbps
 COM3 230.4Kbps
This table provides current and power information that you may need regarding the IO-Link ports.
Use the following procedure to attach IO-Link or digital input/output devices to the ports.
1. Securely attach the IO-link cable between the IO-Link or digital input/output device and the IO-Link
port.
Note: Make sure that you tighten the cables properly to maintain IP67 integrity.
2. If necessary, securely attach a connector cap to prevent dust or liquids from getting into any
unused ports. Connector caps were shipped with the IO-Link Master.
Note: IO-Link ports must have an approved cable or protective cover attached to the port to guarantee IP67
compliance.
3. If necessary, configure IO-Link port parameters using the Configuration | IO-Link Settings page to
configure the port mode.
 If an IO-Link device is attached to the port, the IO-Link LED should now be lit green and the
device is receiving power.
 If a digital input or output device is attached to the IO-Link port, after the port is configured for
