Chapter 1. EtherNet/IP Interface
1.1. Introduction
This section is intended to describe the EtherNet/IP and Modbus/TCP interfaces provided by the IO-Link
Master.
These interfaces provide the ability to retrieve port and device status information, input and output process
data and access to IO-Link device ISDU (SPDU) data blocks.
1.1.1. Functionality Summary
The EtherNet/IP interface consists of:
• Input Process Data blocks that include:
- Port communication status
- PDI valid status
- Auxiliary Input status (pin 2 of IO-Link connector)
- The active event code (zero if no active event)
- The input process data received from the port. This may be
• IO-Link mode: IO-Link device input process data
• I/O Input mode: Input bit status
• I/O Output mode: Output bit status (configurable option)
