Typical architecture
In this type of architecture the I/O system of Premium PLCs equipped with the
TSX
H57 24M/44M
dedicated Hot Standby processor is defined by distribution of field
products or devices on the Ethernet Modbus/TCP network.
Functionally, the products or devices connected on the same Ethernet Modbus/TCP
network can be either of the following types:
b
Client: Twido controller, Modicon PLC, Magelis HMI, W@de remote management
module, etc.
b
Modbus/TCP server: Modicon OTB/Momentum distributed I/O, Modicon STB I/O
islands, Altivar variable speed drives, Lexium servo drives, Inductel/Ositrack
identification systems, etc.
The Ethernet I/O Scanning service allows client-server type exchanges between the
PLC and Ethernet devices communicating in Modbus/TCP protocol. This service can
be used to configure up to 64 stations with periodic read and/or write exchanges
based on the tables of variables (word type) for the target products or devices. The
I/O Scanning service is a function available as standard with
TSX ETY 4103/5103
Ethernet network modules.
The topology of the Ethernet Modbus/TCP network providing the connection
between the PLC Ethernet Modbus/TCP modules and the distributed products/
devices can be bus or ring type with a copper cable or fibre optic medium.
“
Monitored” Ethernet network modules
When the Hot Standby system is configured with Unity Pro software, an Ethernet
module
no.
4-
M
for each Primary PLC and Standby PLC must always be defined
with “monitored” status and have the Ethernet I/O Scanning service.
This status assigns the module with monitoring of both its correct operation and its
electrical connection to its Ethernet switch. A failure (of the “monitored” module or its
Ethernet connection) triggers the changeover from the Primary PLC to the Standby
PLC.

Note
:
Should other Primary and Standby PLC Ethernet modules
be required to be “monitored”, in order to increase the redundant
equipment covered (for example for the SCADA Ethernet
network), an application program must be written in each PLC.
