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 configuration data from the configuration tool.
Chapter 3 CONFIGURATIONS (3) Copy mode When the CPU is switched from RUN to STOP position, the EH-RMP continues to copy the data present in the link output data. This mode is effective when using the EH-150 CPU(EH-CPU308/316) ROM version 02 (software version 2.12) and later.
Chapter 3 CONFIGURATIONS Configuration from configurator 3.2.3 The configuration of the EH-RMP is accomplished by the configurator colled SyConDP. For general information about the configurator, please refer to the manual for this configurator. (1) The entry of the EH-RMP Click the Master icon , and click left-top corner on “Device” area. Select the “Profibus-DP Master”, and set the station address.
Chapter 3 CONFIGURATIONS (3) Make configuration and parameter data Double click on the selected device. And make the configuration data and parameter data. In the configuration data is set the byte offset address from start address of output link area or input link area. For the details of the configuration data and the parameter data to the slave equipment, please refer to the manual of each slave equipment.
Chapter 3 CONFIGURATIONS (4) Set the bus parameter In the menu Set-up/Bus parameter the window shows the actual bus parameters. Changing the baud rate has the consequence, that all other parameters will be re-calculated, The Highest Station Address is the highest bus address up to which the master will search for other master. This should not be set below the master address.
Chapter 3 CONFIGURATIONS Configuration from Ladder Editor 3.2.3 The EH-150 CPU has two link areas of 1024 words (No.1 LINK and No.2 LINK). The EH-RMP operates in the EH-150 system as a LINK module. The first EH-RMP in a rack uses No.1 LINK area and the second EH-RMP uses No.2 LINK area .
