Section 1: Introduction This document will allow the user to setup an Ethernet/IP Tag Datalink (Implicit Messaging) connection between an Omron CS1, CJ1, or CJ2 PLC and an NX-SL5700 safety CPU, through an NX-CSG320 communications gateway. A CS1 PLC will be used as an example. In this configuration, the NX-SL5700 is performing the machine safety functions, incorporating devices such as door switches, safety area scanners, ESTOP buttons, force guided relays, remote safety IO blocks, robots with CIP Safety capabilities, and other safety components. The PLC is performing only non-safety functions such as the monitoring of the safety devices for annunciation on an HMI.
Tags can be mapped from 2 different places when using an NX-CSG320 and an NX-SL5700. • Tags can be mapped from the Safety CPU to the Gateway, and then mapped to Ethernet/IP • Status information from local NX safety IO connected directly to the NX-CSG320 can be mapped directly to EtherNet/IP. This document will show both of these mapping methods. This Tag Datalink (Implicit Messaging Connection) will share: • 2 boolean data points from the CS1 PLC through the NX-CSG320 to the NX-SL5700 • 6 boolean data points from the NX-SL5700 through the NX-CSG320 to the CS1 PLC • IO Module status from local NX Safety IO from the NX-CSG320 to the CS1 PLC. Note:
the names of the NX-SL5700 and NX-CSG320 as shown in Sysmac Studio have been changed from the default for clarity.
