Fig. 10-1: PROFIBUS connections
The P.C.B.s DPM01 (master) and DPS01 (slave) are intelligent
PROFIBUS DP connections in PC104 format. They are used to process
the protocols of the data transfer between the PLC and the decentralized
PROFIBUS input and output units. The built-in microprocessor allows
automatic execution of the entire data transfer, thus relieving the PLC of
real-time tasks.
Data exchange between the PLC and the P.C.B.s DPM01 and DPS01 is
implemented via an 8-kbyte dual-port memory (DPM). The DPM is a
memory which can be simultaneously accessed by the PLC and the
microprocessor of the P.C.B.s DPM01 and DPS01.
