Figure 3.2 – MCS-08 bus system
A basic configuration of type MCS-08 Mult Channel System is shown in Figure 3.2. In this configuration the
gateway module is the master of the internal N-bus and it simultaneously acts as a slave for the external bus.
The gateway connects the external network with the locally installed MCS-08 hardware modules and transmits
commands and responses to and from the external bus. It scans all hardware modules for their status and then
transmits this status information continuously to the external bus controller.
