Figure 6-1. Example of Redundant Architecture with HX3040
Configurations of a Redundant CPU
To configure the CPU to the redundant mode, perform the following steps:
Create a project by selecting the option for redundant CPUs.
Configure the Ethernet interfaces. To implement this procedure, see Wizard for a New
Redundant Project Creation.
Configure the Ethernet interfaces. To implement this procedure, see Ethernet Interfaces
Configuration
Optionally, instantiate DNP and MODBUS protocols. The settings for each protocol can be
found in their respective sections.
The descriptions of each configuration are described in the following sections of this chapter.
Identification of a HX3040 CPU
Throughout this manual, the pair of redundant CPUs will be stated as CPUA and CPUB. The
HX3040 CPU, which contains a project with CPU redundancy, is stated as:
CPUA: the CPU inserted in position 2 of the bus.
CPUB: the CPU inserted in position 3 of the bus.
