2) Select the Settings button next to the Network Type selected, to
display the Network settings window, and select the Driver tab
(Toolbus is shown as example below).
5. Make the necessary selections to facilitate communication between the
PC and the PLC CPU to which the PROFIBUS-DP Master Unit is attached,
and press the OK button.
After making the settings, press the OK button to close the CX-Server inter-
face. In order to verify that the communication has been setup correctly, press
the Test button in the Device Setup tab of the DTM Configuration User Inter-
face. This will initiate a FINS command to read the Unit's profile, i.e. the name
of the Unit and the firmware version.
If the communication has been setup correctly, the response of the FINS com-
mand will yield the required information, which will be displayed in the Device
Information box, in the Description and Firmware Version fields. If the com-
munication is not setup correctly, the two fields will contain three dashes, i.e.
"---", and an Error message will be displayed in the Error Log window of CX-
Profibus. The communication settings must changed to the correct value first.
When CX-Server has been setup correctly, it can be used for
• Configuration download
• Monitoring purposes
Note Since CX-Server is the common driver software for connection between PC-
based CX- programs (e.g. CX-Programmer, CX-Supervisor, etc.) and the
CS1/CJ1-series PLC, all these programs can communicate simultaneously
with the PLC. However, the settings for CX-Server made through each of
these programs have to be exactly the same, to allow simultaneous communi-
cation.
In order to download the parameters sets to the PROFIBUS-DP master Unit,
perform the following sequence.
1. Select the DTM in the network view and right-click the mouse to display the
context menu.
2. Select Download Parameters from the menu, to initiate a download. A
communication channel through CX-Server will be opened automatically.
