Embedded PROFIBUS Slave
The CPU367 contains an embedded PROFIBUS slave that allows the CPU to operate as
a slave on a PROFIBUS DP network and to communicate with a PROFIBUS DP master.
The slave module automatically exchanges data with a master device, but has no bus
access rights. It can only acknowledge received messages or transmit messages to a
master upon request.
This manual describes the operation of the PROFIBUS daughterboard. For details on
CPU operation, refer to the Series 90-30 CPU Reference Manual, GFK-0467.
