Introduction In This Chapter. . . . — Manual Overview — Ethernet Base Controller Overview — Ethernet Standards 11 1--2 Introduction Introduction Manual Overview Overview of this Manual This manual describes the installation and operation of the Ethernet Base Controller (EBC). You will find the necessary information for configuring the T1H--EBC or T1H--EBC100, installing the module, and connecting the EBC to a 10Base-T or 100BaseT Ethernet network. In this manual, the EBC designation is used when the subject applies to both the T1H--EBC and T1H--EBC100. Otherwise, the specific part number will be listed. Other Reference Materials You may find other technical manuals useful for your application. For technical information related to your PC--based control software, your PC or other network masters, please refer to the appropriate manual for that product. • Terminator I/O Installation and I/O Manual (T1K--INST--M) Who Should Read This Manual You will find this manual helpful for setup and installation if you have chosen to use the following: • Network master -- PC-based Control with embedded Ethernet I/O drivers, KEPDirect EBC I/O Server or DirectLogic PLCs/WinPLC using the Ethernet Remote Master (ERM) module • Automationdirect Terminator I/O products Installation and Safety Guidelines A familiarity with Ethernet communications and with the setup and installation of industrial controls is helpful.

Introduction 1--3 When you see the “exclamation mark” icon in the left-hand margin, the paragraph to its immediate right will be a warning. This information could prevent injury, loss of property, or even death. Key Topics for Each Chapter The beginning of each chapter will list the key topics that can be found in that chapter. Introduction When you see the “notepad” icon in the left-hand margin, the paragraph to its immediate right will be a special note. 1 Installation and Safety Guidelines Introduction 1--4 Introduction Ethernet Base Controller Overview The Ethernet Base Controllers provide a low-cost, high-performance Ethernet link between a network master controller and an Automationdirect Terminator I/O slave system. Network masters include the DL205, DL405 DirectLogic PLCs and WinPLCs using the Ethernet Remote Master module (ERM), and PCs using PC--based control software that includes embedded Ethernet I/O drivers or through a compatible OPC server. The T1H--EBC100 also supports the MODBUS TCP/IP protocol. The Ethernet Base Controller serves as an interface between the master control system and the Terminator I/O modules. The control function is performed by the master controller, not the EBC slave. The EBC is positioned immediately to the right of the first power supply and communicates across the backplane to input and output modules. The function of the EBC is to: • process analog and digital input signals • format the I/O signals to conform to the Ethernet standard • transmit the signals to the network master • receive and translate output signals from the network master • distribute the output signals to the appropriate output module in the base Installation and Safety Guidelines I/O Values Stored in Cache Memory The EBC module continually scans all I/O and stores the most recent values in cache memory. The cache memory contents are available to the master controller as a block of data or by individual slot location. The EBC reads all channels of digital and analog modules on each scan. Typically, the network master will request all input and output values at the same time from the EBC. The EBC passes the cache memory values for all channels of all input and output modules. By using this method, very fast response times can be achieved by the network master control system. Various master controllers with EBC slaves are shown below. Example EBC Systems: Various Masters with EBC Slaves MODBUS TCP Masters (T1H--EBC100) DirectLogic PLC/ WinPLC with ERM OR OR T1H--EBC UDP/IP, IPX 10Mbps PC--based Control System Operator Interface Serial Ethernet Hub EBC T1H--EBC100 TCP/IP, UDP/IP, IPX MODBUS TCP 10/100Mbps EBC EBC Introduction Industry Standard Ethernet 1--5 WARNING: For deterministic Ethernet communication you must use a dedicated network of EBC modules connected to your master control system. The EBC modules and the master controller must be the only devices on the network. T1H--EBC/ T1H--EBC100 The EBC installs to the right of the first power supply (see chapter 2 for basic installation steps). For further information about installing power supplies and I/O modules, consult the Terminator I/O Installation and I/O Manual (T1K--INST--M). RS--232 Serial Port An RJ12 RS--232 serial port on-board the EBC module allows serial communication to an operator interface device or other serial device. See your master controller documentation to determine whether this EBC feature is supported. Installation and Safety Guidelines Important Note: The T1H--EBC100 is configured at the factory to look for a DHCP (Dynamic Host Configuration Protocol) server at power up. Refer to Chapter 5 for information on DHCP. Introduction The T1H--EBC module supports industry standard 10Base-T Ethernet communications. It allows up to10Mbps transfer rates between your master controller and and your I/O. The T1H--EBC100 module supports industry standard 10/100Base-T Ethernet communications. It allows up to100Mbps transfer rates between your master controller and your I/O.
