Sample projects for PROFIBUS communication
The following example describes a communication between a master and a
slave system.
The master system consists of a CPU 21x (here CPU 214-1BA03) and a
DP master IM 208DP. This system communicates via PROFIBUS with a
IM 253DP and an output module.
Via this system, counter values should be exchanged via PROFIBUS and
monitored at the output module. The counter values have to be created in
the CPU.
The CPU has to count from FFh to 00h and transfer the counter value
cyclically into the output area of the PROFIBUS master. The master sends
this value to the DP slave. The received value shall be monitored at the
output module (at address 0).
