Device Setup Tab
Settings Box
Configure Button
Test Button
The Device setup tab (see figure above) provides the controls to achieve
communication between the PC and the PROFIBUS Master Unit. It allows
setting of the unit number to identify it on the PLC system and the device
address to identify it on the PROFIBUS network. It also will invoke the CX-
Server interface to setup and test the communication between the PC and the
PLC to which the Unit is attached.
The Device Setup tab has the following components.
The Settings box contains the setting the user must make before setting up
the communication and before testing the communication.

The Configure button invokes the CX-Server communications settings dia-
log. CX-Server is the driver software, providing the communication functional-
ity between a PC and the PLC CPU. It is the basis for the OMRON's CX-One
programs.
CX-Server is provided with CX-Profibus, but it may already be installed on the
PC, if other programs, for example CX-Programmer have been installed.
Note The CX-Server is designed to manage the communication between the PC
and the PLC and also configure the connected PLC. CX-Server currently sup-
ports CS1G-H, CS1H, CS1H-H, CJ1G-H, CJ1H-H CJ1M and CS1G/CJ1G
PLC types.
Section 3-3-3 Connecting to the CS1/CJ1W-PRM21 will provide more details
on how to configure CX-Server.
The purpose of the Test button is to test the communication setup, after CX-
Server has been configured. If the PC and the PLC are connected, selecting
the Test button, will invoke a FINS request message to the PROFIBUS Mas-
ter Unit via the PLC, to read its name and firmware version. If the request suc-
ceeds, both will be displayed in the Device Information Box.
If the FINS request fails (no response), an error message will be displayed in
the Error Log view. In this case the Firmware version field will revert back to
its default contents, i.e. "--- ".
Description
Address of the Unit in the PROFIBUS network. Default value is
1, but it should be changed if there is already another device
with that number.
This number must be the same as the number selected with the
Unit Number Selector switch on the front of the Unit (refer to
2-3-1 Selecting a unit number). This number is used in the com-
munication between the PC and the PLC to transmit the mes-
sages to the targeted PROFIBUS Master Unit
