Configuring The Master; Communication Status; Operation Using Process Data - WEG SCA06 User Manual

7.5.3 Configuring the Master
The way you do the network setup is highly dependent on the network master and the network configuration tool.
It is important to know the tools used to perform this activity. In general, the following steps are required to perform
the network configuration.
1. Program the master to read and write holding registers, based on the defined equipment parameters to read
and write. The register number is based on the parameter number, as shown in table 7.3.
2. It is recommended that reading and writing are done in a cyclic manner, allowing detection of communication
errors by timeout.
7.5.4

Communication Status

Once you install the network and program the master, you can use the LEDs and equipment parameters to identify
some states related to communication.
The LEDs "NS" and "Link" provide information about the state of the interface and communication.
The parameter P0801 indicates the status of communication between the device and the network master.
The network master must also provide information about communication with slave.
7.5.5

Operation Using Process Data

Once communication is established, data is written and read by the Modbus TCP network master automatically.
Using these parameters, the master is able to control the equipment and monitor its operation. It is important to
know the device parameters to program the master as desired for the application.
