Section 1: Introduction This document will allow the user to setup an Ethernet/IP Tag Datalink (Implicit Messaging) connection between a Rockwell ControlLogix or CompactLogix PLC and an Omron NX-SL5700 safety CPU, through an NX-CSG320 communications gateway. 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, or status information from local NX safety IO connected directly to the NX-CSG320 can be mapped directly to EtherNet/IP. This Tag Datalink (Implicit Messaging Connection) will share:  2 boolean data points from the ControlLogix through the NX-CSG320 to the NX-SL5700  6 boolean data points from the NX-SL5700 through the NX-CSG320 to the CompactLogix  IO Module status from local NX Safety IO from the NX-CSG320 to the CompactLogix. This document will explain both of these mapping methods. Note:

the names of the NX-SL5700 and NX-CSG320 as shown in Sysmac Studio have been changed from the default for clarity.

Section 2: Mapping data from the NX-SL5700 to the NX-CSG320 Mapping data from the NX-SL5700 to the NX-CSG320 is used when internal values from the safety program need to be exposed on EtherNet/IP, such as the state of Function Block, as shown below. In this example ESTOP_1_Monitor only turns on when the ESTOP button is not pressed in, and the RESET_IN signal has been applied to reset the Emergency Stop function block.

1. In Sysmac Studio, create the 8 Global Variables in the NX-SL5700 Safety CPU. 2 are ‘Input’ and 6 are ‘Output’ in the Expose Column. The 6 outputs are intended to show the monitoring of internal safety status in the safety CPU, and the 2 inputs are non-safe auxiliary inputs from the PLC, used for non-safety functions such as auxiliary lamps.
