20.6.6 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.

IB-1501268-K

File register

The thermistor voltage acquired with the thermistor input-equipped

remote I/O unit is input after converted to a temperature value per

PLC medium-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.
