I have double checked connection and measure resistance of PT100 and all seems perfect but plc still show value 32767. Maybe something wrong with setting of analog input of plc, maybe there is some trick to configure analog input. I read many description how to configure pt100 and I have no idea what is wrong. Maybe problem is because I am using 2 wire sensor and bridged one wire to second connection sensor with other wire (one wire of pt100 is connected on CM pin).
