Example
This example is intended to show the communication between a master
CPU 8214DPM and a slave CPU 8214DP.
The counters are to communicate via the Profibus and to be displayed at
the output module of the respective partner.
The CPU 8214DPM shall count from FFh...00h and transfer the count
cyclically into the output area of the Profibus master. The master has then
to transfer this value to the slave of the CPU 821xDP.
The value received shall be saved in the peripheral input area of the CPU
and monitored at the output module (at address 0) via the backplane bus.
On the other hand, the CPU 8214DP should count from 00h to FFh. This
count shall also be saved in the output area of the CPU slave and be
transferred to the master via Profibus.
This value shall be monitored at the output module (address 0) of the CPU
8214DPM.
