We have PLC telemecanique with the procesror TSX 67-40. The PLC turn off because black out of power supply. When the power supply comes up, we get indication led red on MEM processor module ( actually have 3 LED indicator: RUN, CPU & MEM).
We already tried to transfer data from terminal to processor of PLC. But we get message that " 15026 reservation PL7-3 not possible".

Please what is solution ?

 

You do not state if the application is in RAM (red) or in EPROM (black).
MEM means something wrong with your application or a cycle time overrrun. If the application is in RAM and the battery in the RAM is bad you have a very good chahge that after a power failure your application is gone. In which case you need to transfer the application to the PLC. You have a V4 processor so you must have XTEL. Use the transfer tool to transfer the complete application. (Don't use PL7-3 for this because then you do not transfer a complete application)
