- TW infrared temperature transmitters
- IO-Link benefits
Gain process insight with IO-Link
IO-Link provides higher resolution than analog
With no scaling in the PLC required, the TW provides resolution of 0.1 °C across the full range of the sensor using IO-Link. Over analog, the resolution is 0.2 °C + 0.03 % of the scaled measuring range.
Device status and diagnostic information
The TW family cyclically provides data on the function of the sensor. Refer to the chart and table below.
PLC data mapping for the TW family
| 0 | Device is OK | Sensor is operating normally |
| 1 | Maintenance required | Cleaning of the sensor face is required |
| 2 | Out of specification | Termperature over / under run, short circuit, check installation |
| 3 | Functional check | Set the parameter |
| 4 | Failure | No reflection signal, parameter error, hardware fault |
