5.1
Precautions for System Configuration
The R60TCTRT2TT2 and R60TCTRT2TT2BW measure temperatures based on the temperature of the terminal block. Thus,
depending on the system configuration used (especially when two or more of the R60TCTRT2TT2 and R60TCTRT2TT2BW
modules are connected next to each other, or the R60TCTRT2TT2 or R60TCTRT2TT2BW is mounted next to the power
supply module or CPU module), the temperature distribution of the terminal block is not uniform due to the effects of heat
generated from modules, and the measured temperature may greatly differ from the actual temperature.
In this case, the error between the measured value and actual temperature can be corrected by the following methods.
Using the sensor correction function
The measured temperature can be corrected to the actual temperature with this function. For details on the sensor correction
function, refer to the following.
