The temperature data of each channel is collected in the CPU as the temperature conversion data
corresponding to the temperature.
(1) I/O assignment
The I/O assignment shall be set as “WX4W" by your programming software or the peripheral
equipment.
(2) I/O allocation
Depending on the module installation position, the temperature conversion data is stored in the
