CS1/CJ1W-PRM21 PROFIBUS Master DTM
Section 2-3
!Caution
Save in the context of the buttons means that the changes made by the user
are saved in the DTM only, i.e. the changes are not permanently saved in the
Project yet. This is indicated by the asterisk next to the DTM in the Network
view. The next time in the same session the GUI is opened, the changes will
still be there. In order to save the changes permanently, e.g. to hard disk,
Click the
File - Save
option from the main menu of CX-Profibus.
Device Setup Tab
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.
Settings Box
The Settings box contains the setting the user must make before setting up
the communication and before testing the communication.
Configure Button
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-Suite
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
2-3-3 Connecting to the CS1/CJ1W-PRM21
will provide more details
on how to configure CX-Server.
Test Button
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. “--- “.
Device Information Box
The Device Information Box contains information obtained from the PROFI-
BUS Master Unit, through the communication.
Control
Description
Station Address
Address of the Unit in the PROFIBUS network. Default value is
1, but is should be changed if there is already another device
with that number.
Unit 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 the
CS1/CJ1W-PRM21 Operation Manual, W409-E2-
@)
. This num-
ber is used in the communication between the PC and the PLC
to transmit the messages to the targeted PROFIBUS Master
Unit
