processor base unit. The following illustration shows some possible
arrangements for MODBUS Master connections.
The MODBUS RTU slave devices are connected to one or more of the serial
ports on the controller; a usual arrangement uses a multi-drop (RS-485)
arrangement. The engineering workstation and the MODBUS TCP devices
are shown connected to the Ethernet ports on different networks.
Alternatively, these devices can be combined onto one network. Refer to the
AADvance System Build Manual for more details about physical connections
Controller IP Address The AADvance controller stores its IP address data in non-volatile memory in
the 9100 processor base unit. The data is independent of the 9110 processor
modules in the controller, and so the controller keeps the address information
when you remove a processor module.
You must set up the IP address data when you create a new system, or if you fit
a new processor base unit.
