I/O Status
PLC300 | 8-5
IOE Card (thermistor reading):
The IOE cards have five inputs for reading PTC, PT-100 or KTY-84 thermistors.
In the user program (ladder), the thermal sensors are treated as analog inputs (AI101...AI105
or AI201...AI205).
The status screens show the temperature in each sensor, between -20 °C and +200 °C.
If the monitored temperature is lower than -20 °C, the thermal sensor is probably with a
broken wire, which is indicated by the symbol: “=/=(FP)”.
