so Long as it is the same version with the previous Td200,You don't need to reprogram it.
The Td 200 takes its information from the Plc and at such,immediately you establish communication with the Plc,the Td 200 will gather the necessary program from the PLC....
Dear Salmanahm,
Every time you need backup program. if you have not this backup. Then you reprogram for your machine. what type of fault you have in your old TD200.
Best regards,
