HMS Anybus CompactCom 30 User Manual

Network Specific — Modbus-TCP 24 (38)
11.3 Network Configuration Object (04h)
The instances in the Network Configuration Object have been rearranged for the Ethernet
based modules for consistency. Network specific instances are moved to instance number 20
and onwards. This is done to increase the number of instances in the section that is not network
specific.
If the host application is using any of the parameters below, the software must be updated to
use the new instance numbers.
Parameter Name 30-series Instance # 40-series Instance #

11.4 Modbus Host Object (FAh)
Attribute 30-series 40-series Change/Action/Comment
#2, Product Code Default: “Any-
bus-CC Modbus-
TCP (2-Port)”
Default: “Anybus
CompactCom 40
Modbus TCP”
If the attribute is implemented in the host ap-
plication, it overrides the default value and
there is no difference between the 30-series
and the 40-series.
If the attribute is not implemented, the default
value is used.
#11,Modbus read/
write registers com-
mand offset
- -
In the 30-series, this register address offset is
only applied when accessing holding regis-
ters with the command Read/Write Multiple
registers (23).
The 40-series applies this register offset to all
holding register access, i.e. commands 3, 6,
16 and 23.
11.5 Ethernet Host Object (F9h)
Attribute 30-series 40-series Change/Action/Comment
#4, Enable Modbus-
TCP
Available Removed Attribute removed in the 40-series. The Com-
pactCom will never request this attribute.
Nothing needs to be changed in the host
application.
11.6 Process data
In the 30-series modules, writing to the ADI register area would only result in a Set_Attribute
command to the application (Application Data Object (FEh)) if the ADI was not mapped to read
process data. For the 40-series, all register writes to the ADI area also results in a correspond-
ing Set_Attribute command to the host application (Application Data Object (FEh)), as well as
updating of the process data.
