Hi Muthamiz, To read the thermocouple value; you have to read the raw value of the thermocouple then divide it over 10. Good Luck, |

No, you can connect 8 termocouples.
How to read in PLC look at How and for which analog measurements can you use the function FC105 "SCALE" to convert the integer values (INT) into real number values? Best regards, Hristo Mihalev |
