plc and labview

To measure and display temperature from a thermocouple you don't need a PLC and LabView but a analog card and just LabView ..
Go to National Instruments web site and check out their offer of analog cards; these cards come with LabView drivers and can be configured to work with several types of temeprature sensors including thermocouples ..

plc labview

Everything deends on the type of the PLC that you have ..
To connect a thermocouple to a PLC you will need a thermocouple or analog I/O module, and to interface PLC with LabView you can use RS-485/RS-232 or any other bus that your PLC and your PC may have in common ..

can i connect siemens plc to labview

LabView is a very powerful piece of software ..
It has provisions made for communication with almost everything, using dedicated I/O cards, or build-in standard PC hardware (serial port, for example) ..

Check out if your PLC can exchange data via serial port (if it has one) or a BUS (RS-485 .. MODBUS .. anything) ..
If it can then the answer is YES ..
