| OpenDAC(R) I/O System NETWORK INTERFACES OpenDAC(R) for Ethernet FEATURES * Use Ethernet to Control/Monitor up to 32 Analog and/or Digital I/O Channels using OpenLine(R) I/O Modules * Network Multiple OpenDACs(R) * 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(R) SYSTEM APPLICATIONS Stand Alone Control Local Control & I/O Remote I/O Distributed I/O SCADA RTU OpenDAC(R) I/O System GENERAL DESCRIPTION The OpenDAC(R) 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(R) analog or digital I/O channels is stored and constantly refreshed. OpenDAC(R) 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(R) for Ethernet supports the OpenLine(R) Smart Module Protocol (SMP) that allows field calibration and parameter setup of I/O modules. Each OpenDAC(R) 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(R) 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(R) 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(R) 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(R) 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(R) scans and stores the I/O configuration and makes the information available to the master. In addition to simple On/Off instructions, the OpenDAC(R) 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 Grayhill, Inc. * 561 Hillgrove Avenue * LaGrange, Illinois 60525-5997 * USA * Phone: 708-354-1040 * Fax: 708-354-2820 * www.grayhill.com OpenDAC(R) 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.
