The CPU 3xx-PN takes initiative here, using PUT and GET The usage is explanined here: http://support.automation.siemens.com/WW/view/en/18610307 No extra program in the system with the Lean CP 2) a secondway is to declare the system with the Lean CP as IO device of the CPU3xx-PN acting as IO controller. The both sytems will echange data over fictive I/O In thewith the Lean CP, ou must use special PN - FCs See http://support.automation.siemens.com/WW/view/en/31764614 It seems that you have two separated projects. It is easier to put all together in one project.

The IM CPU would work with T-Communication blocks and the CP would work with AG_SEND / AG_RECV. This works quite fine too, in both ways. Best regards J_Bell
