10.3.1 Program Description
Two programmable controllers (S5-115U and S5-95U) must be linked via
the SINEC L2-BUS.
For the example, a simple data exchange of two bytes in both
communications directions has been selected. PLC 1 sends changing data
to PLC 2. In PLC 2, these data are returned to PLC 1.
