Omron has introduced EtherNet/IP Remote I/O blocks with both short- and open-circuit detection to reduce troubleshooting time and maintain productivity. The ERT1 series EtherNet/IP slave I/O blocks are available as high-density, 32-point, in-panel IP20 models with removable cage clamp I/O connections and power connections that simplify installation and servicing. Water-resistant IP67 rated, 16-point I/O models accept SmartClick and standard M12 connectors for I/O, power, and network connections. The ERT1 series remote I/O blocks have been conformance tested for interoperability with EtherNet/IP devices from a wide range of suppliers, in addition to Omron’s EtherNet/IP masters for CJ and CS series PLCs.
Enables Faster Diagnostics
The ERT1 I/O block detects shorts at the sensor and prevents the short from affecting the rest of the inputs. It also has LEDs to indicate which input or output is shorted, and I/O bits that alert operators when an input or output is shorted or open (broken sensor or broken wire to sensor). Each group of 16 I/O has its own power terminals and the communications module has its own power terminals, so the module can monitor if power to the I/O terminals is lost. The LEDs are yellow for on, red for shorted, red flashing for disconnected, and “off” for off. The short- and open-circuit detection can be enabled or disabled for each input/output.

The EtherNet/IP network can be configured using Omron’s CX-One Automation Software for master and slave devices on the network. CX-One configures and supports all ODVA’s CIP-based networks from a single software license without additional plug-ins.
