Configuring the Master
Testing CX-Server setup

4. Select the Network Type to be used as connection between the PC and
the Unit. The available options may include other PLC systems or Commu-
nication Units, which are setup to act as a gateway. Refer to CX-Server
Runtime user Manual (W391) for details on configuring CX-Server.
Note 1) For further explanation, only the direct connections between the
PC and the PLC on which the Unit is attached are considered.
These include ToolBus and SYSMAC WAY.
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).
3) Although SYSMAC WAY can be used for the majority of applica-
tions, it is limited in a sense that it can not handle the absolute
maximum of I/O configuration and parameters, i.e. it can not han-
dle a slave device which requires 244 I/O modules and 244 pa-
rameter bytes. Toolbus does not have that limitation.
5. Make the necessary selections to facilitate communication between the
PC and the PLC CPU to which the PROFIBUS 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
command will yield the required information, which will be displayed in the
Device Information box, in the Description and Firmware Version fields. If
the communication is not setup correctly, the two fields will contain three
dashes, i.e. "---", and an Error message will be displayed in the Error Log view
of CX-Profibus. The communication settings must be changed to the correct
value first. Refer to Appendix D Configurator Error and Warning Messages for
more information on communication and download errors.
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.
