Direct data exchange with multiple receivers (1:n)
The following figure shows the direct data exchange with multiple S7-1500 CPUs. In this
case, the sending S7-1500 CPU provides the data of its output transfer areas to multiple
S7-1500 CPUs. Each receiving S7-1500 CPU has its own input transfer areas.
①
Transfer relation between the user program and the transfer area. The user program and the transfer areas ex-
change input and output data via this path.
②
Communication relation for direct data exchange You configure the communication relations in STEP 7. You create
transfer areas for direct data exchange in the properties of the communication relations.
