2.4.3

Configuration of the Ethernet Interface

To configure the Ethernet interface of the communication module, refer to item 2.3.3.
2.4.4

Configuration of the Communication

In order to configure and use the Modbus TCP, follow the steps below:
With the module installed, during the recognition stage, a warning message will be displayed on the product

HMI, and the MS and NS LEDs test routine performed. After this stage, the MS LED must turn on in green.
Observe the content of parameter P0723. Check if the module was recognized. The detection is done

automatically and does not require the user's intervention.
Set the parameters as desired for the application:

Configurations of IP address and communication rate are explained in item 2.3.3.

I/O configuration: program in P0727 the number of words to be exchanged with the network master.

For this adjustment being complete, it is necessary to program a value different from 0 (zero) in
parameters P0728 to P0739 (see item 3).
Once the parameters are set, if any of the parameters described in the previous item are changed, it is

necessary to restart the equipment.
Once the equipment is set, it is necessary to configure the communication in the master of the network:
Configure the master to access the Anybus I/O words as per the memory map presented in item 2.4.5.

To configure the timeout of the communication and order of the bytes, use the web browser according to

the figure 2.10.
Figure 2.10: Webpage with configuration of the timeout and order of the bytes
The field "Comm tmo" is used to configure the timeout of the TCP connection and the field Process tmo

allows to program the time for the detection of communication error.
The field "Word order" configures the order of the

big endian
or (byte 0 least significant).
Connect the network cable to the module.

If everything is correctly configured, the NS LED of the module will be on in green and the LINK LED will

start to flash indicating normal activity in the network.
NOTE!
For further information on the parameters mentioned above, refer to item 3.
