Hello forum, recently I have a problem to communicate a s7-317 with a s7-1200 using a CM 1242-5 (slave), i did a succesfull comm using Tia Portal for both PLCs. Right now i'm having some difficulties to configure the s7-300 in step 7.

I'll attach both, tia portal and step 7 projects for you review, and the capture of the error.

The problem I see, is that the s7-300 doesn't see the slave, and throw an error "Device configure isn't the one installed" but i'm using the gsd from the website (si01818e.gsd).
