20.6.6 Thermistor Input Interface

 By connecting the remote I/O unit with thermistor, up to 12 points of thermistor input are available.

For details on units with the thermistor input function, refer to "4.10 Remote I/O Unit".

 Up to 12 points of the thermistor are detected in the ascending order of the channel No. and station No. of the remote I/O

unit. The file registers outputting temperature information are assigned 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 signals]

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.

File register

The thermistor voltage acquired with the thermistor input-equipped re-

mote I/O unit is input after converted to a temperature value per PLC me-

dium-speed cycle.

One station of remote I/O has 4 thermistor inputs, thus 4 PLC medium-

speed cycles are required for the inputs of one station.
