17.6.5 Thermistor Input Interface

(1) By connecting the remote I/O unit with thermistor, up to 12 points of thermistor input are available.
For details on the unit which has thermistor input function, refer to "General Specifications: Remote I/O Unit".
(2) Up to 12 points of thermistor are detected in the ascending order of the channel No. and station No. of the remote I/
O unit. The file registers which output the temperature information are assigned to the inputs (thermistor input n
(TIn)), but are not assigned to the 13th or later thermistor input. The relationship between thermistor inputs and file
registers is as follows:
[PLC input signal]
Through the interface you can read the temperature sensed by a thermistor connected to the designated connector
of thermistor input-equipped remote I/O unit.
