MODBUS RTU MASTER FOR CP340/341/441-X (NO DONGLE REQUIRED)

Dear,

        I'm using these function blocks with my CPU313+ CP341 because i don't MODBUS dongle inserted. I just created a sample program using these four function blocks and it covered all usable memory and left no free space. If you get it please tell me where i'm making mistake. CPU313 have 12KB storage...

Dear TIBI68,

We used your driver Modbus RTU Master with MBMAREQH block. It's fantastic!!!!

Know that your development brings real benefits to specialists around the world.

From Russia with love!

Dear All,

I try to use this programm on JBUS (instead of Modbus), but the range of input registers provided by the slave is from 25000 to 25249.

When I try this code adresses in "Start input" and "end input" of the block MBMAREK, i get an error (adresses out of ranges)

I work with a CP341 and S7 simatic Manager

Someone could help please ??

Thanks
