The OpenDAC® for Ethernet network interface 72-ETH-T000 is a remote slave that responds to Modbus/TCP commands that it receives over the network. The status and configuration of up to 32 OpenLine® analog or digital I/O channels is stored and constantly refreshed. OpenDAC® for Ethernet is self-configuring. On power up, the controller will identify the types
of I/O modules present. The 72-ETH-T000 will then continuously scan and update the digital and analog modules. Digital input channels can be setup for latching operation. The OpenDAC® for Ethernet supports the OpenLine® Smart Module Protocol (SMP) that allows field calibration and parameter setup of I/O modules.
Each OpenDAC® or third party device on the network is assigned a unique IP address. There are three methods of assigning the internet protocol address -BOOTP, DHCP, and a static method. The controller 72-ETH-T000 is shipped with the default IP address of 128.0.0.1. The IP address can be changed using a web browser. The web browser can also be used to select BOOTP or DHCP to assign the IP address. Communication data rates are either 10 Mbps or 100 Mbps.
OpenDAC® automatically detects whether it is connected to a 10Base-T or 100Base-TX network, eliminating switch settings and simplifying set up. Network and controller status can be monitored by status LEDs.Each OpenDAC® incorporates a communication watchdog timer that monitors communication from the Modbus/TCP master. When the watchdog is enabled and the slave does not receive a valid Modbus/TCP message within a specified time, the OpenDAC® will set all output modules to the stored fault-state values. Should a valid message be received, the timer is reset and communication resumes. All configuration parameters are displayed and modified using a web browser. The configuration parameters are password protected to provide security against unauthorized access.
