OpenDAC® I/O System NETWORK INTERFACES OpenDAC® for Ethernet FEATURES • Use Ethernet to Control/Monitor up to 32 Analog and/or Digital I/O Channels using OpenLine® I/O Modules • Network Multiple OpenDACs® • 10Base-T and 100Base-TX Support • Extremely Fast Response Times over Network • Support Modbus/TCP Protocol and HTTP • Use Web Browser for Configuration, Monitoring and Control of I/O modules • Diagnostic LEDs • CE Certified • DIN Rail Mounting • Modbus TCP ETHERNET UNIT ON OPENDAC® SYSTEM APPLICATIONS Stand Alone Control Local Control & I/O Remote I/O Distributed I/O SCADA RTU OpenDAC® I/O System GENERAL DESCRIPTION The OpenDAC® for Ethernet network interface 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 unit 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 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. ANALOG & DIGITAL I/O MODULES OpenDAC® for Ethernet connects directly to one or two 16 channel racks. Any combination of analog and digital I/O modules may be used. On power up, the OpenDAC® scans and stores the I/O configuration and makes the information available to the master. In addition to simple On/Off instructions, the OpenDAC® allows you to: • Read linearized thermocouple and RTD temperature values • Detect rising or falling edges • Latch momentary input events • Set the level of analog outputs OpenDAC 2 G rayhill, Inc. • 561 Hillgrove Avenue • LaGrange, Illinois 60525-5997 • USA • Phone: 708-354-1040 • Fax: 708-354-2820 • www.grayhill.com OpenDAC® I/O System DIMENSIONS In inches (and millimeters) 4.1(104,26) 3.9 (99,56) OpenDAC for Ethernet DEFAULT CONFIG POWER RESET STAT DIN RAIL LATCH LINK 2.6 (65.48) PIN 1 2.3 (57.17) TO CENTERLINE OF DIN RAIL CHANNEL SPECIFICATIONS Supply Voltage: 4.80 to 5.25 Vdc Supply Current (less modules): 1.0 amp max.
