Hello!

Does anyone have working sample for Siemens modbus master on ET200SP remote io rack or knowedge how it can programmed on step7 classic easily? Jesper maybe?

Card is 6ES7137-6AA00-0BA0

I allready asked this from Siemens and they have sample program only for TIA portal and it is totally different (maded with indirect addressing and SCL code)

^Thanks, but they are for ET200S system, not for newer ET200SP.

I have made modbus master earlier with et200s, but programming was there different than with this newer et200sp.
I have manual for ET200SP, but there is some questions still how I should program communication.
