Configuration
The communication parameters for the Modbus line are the most important thing to configure first. As described earlier,
these parameters must be identical in both the master unit and slave units, since they define the structure of messages
and the transmission speed.
The default configuration values of a Corrigo E controller are shown in the figure below.
Corrigo E is set to Slave 1 address by default. If more devices are added, a new address can be set for each device using
the Corrigo E display or E tool.
Transmission mode
Corrigo E uses the RTU transmission mode; not to be confused with the ASCII mode. The settings for the transmission
mode must be the same in the master unit and the slave units, since Modbus/RTU cannot understand Modbus/ASCII
messages. The Word length configuration parameter is always 8 for Modbus/RTU.
Writing values
To override the Corrigo E output values, set the output to manual mode using a Modbus signal. Then set the ..._ManSet
signal to the desired layer. These signals are listed in Chapter 5: Holding Registers Remember that only values with a
default value are adjustable. The are described in the chapters Coil Status Register and Holding Register.
Reading values
An effective way to read values is to display multiple variables simultaneously. For example, to read all analogue outputs,
set the Modbus query to the values shown in the figure below. The first analogue output variable starts at address 54
(QAnaOut.AQ1). To read address 54 to 58, set the length to 5. The Modbus answer will then communicate the 5 values
in a single message, making the communication more effective.
