Thermistor input n

This signal enables the following temperature value to be read from the file register: temperature acquired with the

thermistor that is connected to the designated connector of the thermistor input-equipped remote I/O unit.

This signal outputs the temperature value acquired with the thermistor in 0.1 ℃ units.

(Example) 0x01F5 = 501 -> 50.1 ℃

When the thermistor is disconnected or short-circuited, this register is not updated.

The below shows the data update cycle of the thermistor input and the interface:

(2) Thermistor short-circuit (TISRT: ZR13041)

Thermistor disconnection

This signal notifies that the thermistor is not connected to the thermistor input-equipped remote I/O unit, or the thermistor

is disconnected or ground-fault.

When the thermistor is unconnected, disconnected or ground-fault, the bit of the corresponding channel is turned ON.

The thermistor input (TI0 to TI11) of the channel which is disconnected or ground-fault is not updated.

IB-1501616-D

The thermistor voltage acquired with the thermistor input-equipped remote I/O unit is in-

put 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.

Thermistor input channel 0 disconnection

Thermistor input channel 1 disconnection

Thermistor input channel 11 disconnection
