Chapter 2 STRUCTURE and SPECIFICATION 2.3 Supported EH-150 I/O modules The EH-IOCP supports the EH-150 I/O module types listed in table 1. Any combinations of supported modules are allowed. However, the total data size (IN + OUT) must not exceed 208 words. Table 2.1 Supported I/O modules Module Name Module Type...
Chapter 3 CONFIGURATIONS Chapter 3 CONFIGURATIONS 3.1 System configurations The EH-IOCP is mounted next to the power supply in the expansion base as shown in below. Two modules per CPU 0 to 2 slot of basic unit only(can’t mount other slot) 10 11 12 13 14 15 Basic unit Extension unit...
Chapter 3 CONFIGURATIONS 3.2 Start up To operation this module normally, the making a setup which is shown in the following figure is necessary. (1) Set the DIP switch. Refer to chapter 3.2.1 . (2) Set the termination switch. Refer to chapter 3.2.2 . (3) Set the node address.
Chapter 3 CONFIGURATIONS 3.2.3 Node address The node address of the EH-IOCP has to be set before connecting to the fieldbus. This is done with two rotary switches On the module, this enables address setting from 1-99 in decimal format. The example of the setting is shown in figure 3.2 .
The latest version of this GSD file can either be downloaded from the webpage http://www.hms.se/fbfiles.htm or received by contacting Hitachi. The user must add the GSD file for the EH-IOCP in the network configuration program device data base as shown in the following example, using HMS System Configurator DP.
Chapter 3 CONFIGURATIONS 3.3.2 Station address The station address is the node address set by the rotary switched as described in chapter 3.2.2 . Choose [Edit device] in the [Device database] menu , or Double-click on EH-IOCP icon. Set the station address Fig.
Chapter 3 CONFIGURATIONS 3.3.4 Parameter data During initialisation, the EH-IOCP identifies all installed IO modules. These identities are compared with the parameter data received from the master during parameterisation of the EH-IOCP Profibus-DP slave node. If a mismatch is found in one or more identities, the parameterisation of the node is rejected and the node will not go on- line.
Chapter 4 Installation and Wiring Chapter 4 Installation and Wiring 4.1 Installation of Module EH-IOCP can be installed next to the power supply module. Install and uninstall the module after turn off the base unit power source. 4.2 Loading the Module (1)Installing Hook the claw at the lower section of the module to the hole in the base.
Chapter 4 Installation and Wiring 4.3 Wiring For information about installation of the Profibus DP fieldbus, please refer to the document : Installation Guideline for PROFIBUS-DP/FMS from PNO, Order No. 2.112. Profibus homepage on the Internet: http://www.profibus.com 4.3.1 Profibus port EH-IOCP has D-sub 9 pin female connector for Profibus port.
Chapter 4 Installation and Wiring 4.3.2 Cable parameters The bus cable is specified in EN 50170 part 8-2 as ”Cable Type A”, and should comply with the parameters in the table below. Cable Type B, which is also described in EN 50170, is outdated and should no longer be used.

Chapter 5 Normal Operation Chapter 5 Normal Operation 5.1 Start-up Sequence When the power is turned on the EH-IOCP will perform an internal hardware check. As a LED test, the STATUS led will flash Green -> Red -> Green -> Red. When the initialization sequence is finished the STATUS LED will be constantly lit green, indicating that it is ready to exchange data.
Chapter 6 Indications Chapter 6 Indications The EH-IOCP is equipped with four indication LED’s on the front of the module: the EH-IOCP Status LED and three Profibus- DP Status LED’s.
