3.2. Example 2
In this example, the program controls the hysteresis value on the second channel of the TR-101 device, depending on
the temperature on the sensor of the first channel. In the text 16 – MODBUS ID of the device is TR-101; 4 - address of
the channel temperature register 1; 47 is the address of register for the hysteresis of the second channel.
The program uses registers in the field of current user settings 5500-5749. Registers 5500 and 5501 are
reserved for the values respectively of the lower and upper temperature limits and the registers 5502 and 5503 are
for the hysteresis value to be set in TR-101 if achieving the temperature respectively the lower or upper limits.
These registers are read-only. To change them, you should be in configuration mode (see it. 5.3.4), then write the
desired values to addresses of the respective editable settings. These addresses are obtained by subtracting 250
from the address current value. Thus, temperature limits are recoded into the registers 5250 and 5251, and the
hysteresis – 5252 and 5253. Then, in order for the changes to take effect, you need to give the commands "Save"
and "Apply" (for example by writing 4 to the register 120).
