3.2 Start up
To operation this module normally, the making a setup which is shown in the following figure is necessary.
3.2.1 DIP switch
The EH-RMP can be configured to run in different modes depending on the users requirements.
The configuration is accomplished by the switch placed on the right side of the EH-RMP.
(1)Clear mode
When the CPU is switched from RUN to STOP position, the EH-RMP outputs the zero data to Profibus.
But the link output area(WL) is not cleared.
Switch Position
1 Don’t care
2 Don’t care
3 OFF(default)
4 OFF(default)
(2)Freeze mode
When the CPU is switched from RUN to STOP position, the EH-RMP freezes the output data with the value present
when the switch is performed.
The "SET RESET" and the "FORCED OUT" function from the programming tool for EH-150 PLC are invalid.
Switch Position
1 Don’t care
2 Don’t care
3 ON
4 OFF
Note 1: The configurations will affect the behavior of the output area when the
CPU is turned from RUN to STOP.
The behavior of the input area are the same in all modes, the entire input area are
always copied.
Note 2: Don't operate this switch while EH-RMP is working.
(1) Set the DIP switch. Refer to chapter 3.2.1 .
(3) Set the configuration data from the configuration tool.
. Refer to chapter 3.2.3 .
(4) Set the LINK parameter data from the Ladder editor.
. Refer to chapter 3.2.4 .
(2) Set the termination switch.
. Refer to chapter 3.2.2 .

(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.
Switch Position
1 Don’t care
2 Don’t care
3 OFF
4 ON
3.2.2 Termination switch
The start node and the end node in a Profibus-DP network has to be terminated to avoid reflections on the bus line. The
EH-RMP is equipped with a termination switch to accomplish this in an easy way.
If the module is used as the first or last module in a network the termination switch has to be in ON position.
Otherwise the switch has to be in OFF position.
Termination switch Bus termination
ON ENABLED
If the module is the last or first module, the bus termination has
to be set on, or an external termination connector has to be used.
OFF DISABLED

3.2.3 Configuration from configurator
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.
(2) The entry of the slave device
Click the I/O Slave or Module Slave icon, and click left side on “Device” area.
Select a slave device, and set the station address.
Following figure is the example of selected the EH-IOCP of Modular Slave.

(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.
Fig. 3.4 and Fig. 3.5 is the example for EH-IOCP.
Fig. 3.4 Configuration data for EH-IOCP
Fig. 3.5 Parameter data for EH-IOCP

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.
Auto_Clear Mode ON, the DP Master leaves the user data transfer and switches the outputs of all assigned DP-slaves to the
fail-safe state.

Chapter 3 CONFIGURATIONS
3-7
3.2.3 Configuration from Ladder Editor
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 .
For the EH-RMP, specify the output area size of the link ( maximum 256 words).
Top Assign No. is fixed to WL0. (for No.2 LINK is WL1000.)
Last Assign No. is between WL0 and WLFF. (for No.2 LINK is between WL1000 and WL10FF.)
Input area of the link is always fixed from WL200 to WL2FF ( for No.2 LINK is WL1200-WL12FF).
Fig. 3.7 LINK Parameter
NOTE1:
All address in the link area are word addresses.
All address in the configurator(SyCON DP) are byte addresses.
NOTE2:
The EH-150 CPU uses 1024 words for the EH-RMP.
But the effective data area is 256 words of input data and 256 words of output data.
512 words of the remainder are reserved.
