Target Device(s) and Protocol 1.1 Introduction This section defines the types of I/O Devices that are targeted by this driver. 1.2 Device Manufacturer HITACHI 1.3 Device Definition Hitachi programmable controllers: H200 series, H700 series 1.4 Communications Method Serial connection. Either direct to the programming port or via a COMM-2H module. Tcp/Ip connection. Via a LAN-ETH module. 1.5 Communications/Hardware Configuration Serial connection The programming port uses RS232 into a 15 pin connection. The COMM -2H module allows for RS232 or RS422 connection. Using RS422 connection allows up to 32 multidropped HITACHI controllers Wiring Diagrams Refer to H - Series, Intelligent serial port module manual. hitachi_extract.doc 4

The functions related with IP address setting is shown in the following: N0 Functions Mode setting switch Description 1 IP Address information setting IP address is set newly.set the information of IP address etc. in IP address setting area. Then write plc program an run to finish the setting. 2 Reference of IP address setting IP address setting is read. IP address informationis read to IP address eading area. 3 IP address default setting IP address returns to default value.

For the kernel, the debug trace messages and the Stats.Special counters are documented. 2.2 Driver Name HITACHI 2.3 Communication forms Serial Connection Forms Boards Form Board Type If using a serial board or COM port, you should enter COMx. Address If using a serial board or COM port, you should enter 0. I/O Port Leave this field blank. Interrupt Leave this field blank. Special Options Leave this field blank Ports Form Baud Rate This value should match the setting of the PLC is recommended. Data Bits 7 top Bits hitachi_extract.doc 9

10 1 Parity EVEN_P Special Opt When using the H-200 a special option of -H should be used in this field to enable hardware hand shaking IO Devices Form protocol HITCAHI Address The address format is as follows LLUUMMPP[ :n][ /tm Where LL UU MM PP n m is the Lump address Loop No in two hexadecimal digits is the Unit No in two hexadecimal digits is the Module No in two hexadecimal digits is the Port No in two hexadecimal digits is optional office number (ie station address) in decimal. is a single optional hex digit to set the TM Response byte in the protocol. If the optional office number is included then the driver will include this information in the protocol request and thus support multi-dropped connection to multiple devices via RS422. The /Tm is 0 to F and the time is 0 to 160 ms, the response TM value is 10ms, the default value is 0 for a maximum communication speed TcpIp Connection Forms Boards Form Board type TCPIP. Address This should be 0. I/O Port hitachi_extract.doc 10

11 Leave this field blank. Interrupt Leave this field blank. Special Options Leave this field blank Ports Form Baud Rate Leave this field blank Data Bits Leave this field blank top Bits Leave this field blank Parity Leave this field blank Special Opt User must enter the destination IP address of Ethernet module. Use the following format: -Ia -Pn -T where: a Is the destination IP address in standard Internet dot format. (For example ) n The destination Port number. For using task code protocol, this can only be 3004 or -T Forces the driver to use TCP (the default), rather than UDP (-U) IO Devices Form protocol HITCAHI Address The address format is as follows LLUUMMPP hitachi_extract.doc 11
