Hi,

I'm exchanging data between two CPUs (1510SP-1 PN and 1212C) by PUT/GET blocks. I want to exchange 1300 bytes by the PUT/GET. I can't to change the type of communication and can't to use more than one PUT/GET block to communicate. I have idea to store a pointers to data in array and use loop to send or receive all 1300 bytes of data but I don't know how to store pointers in array... Is it possible?

Thanks for the help

Hello ITA2021,

There is a maximum amount of data that can be sent per job through the PUT / GET instructions. The size of user data that can be transferred with these instructions can be found at the following link:

Useful information about the instructions for S7 communication

You should be able to call the PUT/GET statements several times without problem to transfer more data. Be careful that only one job is active at the same time.
