RUN LED is blinking every 0.5 second and temperature value is not changed

RTD module is corrected for its measurement circuit before it is delivered from factory. In this case, the module uses Y***5. Check if Y***5 bit for the module is set in CICON memory monitor and if it is already set, then check if this bit is used through scan program or communication..

 

LED is blinking every 0.3 second temperature is stopped at around -250ºC (or -50ºC)

If RDT module is not connected with power 24V, this error occurs.
Connect 24V power at the bottom of RTD module to solve this problem.
