7.8.11.6. Application of Logical channel in the Controller mode
See also:
Chapter 7.8.7. Logical Channels - Controller mode
Task:
The task is to configure the Controller to control (via RS-485) the Heater to get a
constant object temperature. The Controller uses a logical channel in the Set point value
Mode (temperature 85ºC) and the feedback signal comes from the Pt100 sensor.
Solution:
Before measuring and regulating the temperature, the user should configure the device
as follows and then connect the RTD sensor and the Current converter to the device. An
example of the connection is shown in
Fig. 7.74. Schematic diagram for the hardware configuration FUN4 and MB1 Modbus port
The first step is to configure appropriate parameters for the
Controllers
menu according to
7.13.2.1. Application of the Controllers
. Next, configure logical channels as follows:
