Sample RS485 network configurations
8.6.3.1
Single-master PPI networks
Introduction
The following network configurations are possible using only S7-200 SMART devices:
●
Single-master PPI networks
●
Multi-master and multi-slave PPI networks
●
Complex PPI networks
Single-master PPI networks
In the sample network in the figure below, a human-machine interface (HMI) device (for
example, a TD400C, TP, or KP) is the network master:
In the sample network, the CPU is a slave that responds to requests from the master.
8.6.3.2
Multi-master and multi-slave PPI networks
The following figure shows a sample network of multiple masters with one slave. The HMI
devices share the network.
The HMI devices are masters and must have separate network addresses. The
S7-200 SMART CPU is a slave.
