User data in engineering format
The 6ES7431-7KFOO-0AB0 does not support the values defined for S7 for the overreaches and sub-
1
ranges of thermocouples. Depending on the situation, underflow (32768) or overflow (327767) is dis‐
played when the module reaches the end of the thermocouple operating range defined for S7.
Operation of thermocouples above the specified temperatures is possible.
2
The specified accuracy is at the lower end of the range and is better at higher temperatures.
The accuracy of the thermocouple module at temperatures other than those specified can be calculated
using the limit values for the accuracy of input voltage and emf/°C of the thermocouple at the required
temperature.
