NOTE
For further information regarding Fieldbus interfacing including downloadable support files, go to the
HMS website at http://www.anybus.com, choose the link to the support page, select the Anybus-
CompactCom product type and then your network type.
Baud Rate
This is a read-only parameter. The modules are set to use the automatic baud rate mechanism where the Fieldbus
Master defines the speed of the connection. After connection, for some Fieldbus types, the actual speed of the Fieldbus
will be displayed in this parameter.
For CC-Link Fieldbus, the Fieldbus Master does not set the network baud rate and therefore this parameter must be
set manually according to the application specific network baud rate.
Max. Exchange Area Size (Input+Output)
This is a read-only parameter. It defines the (fixed) maximum size of the exchange area (total of both Input and
Output Areas) available for messages between the Fieldbus Master and the Fieldbus module.
