Architecture with shared products on Modbus and shared I/O on Ethernet
Modbus/TCP
In this type of architecture the Premium Hot Standby system products, peripherals
and devices are:
b
Shared on a Modbus/TCP Ethernet network (with a bus topology as in the
example below)
b
Shared on a Modbus link, thus allowing it to support the many varied peripherals
and devices (Schneider Electric or third-party) equipped with a slave Modbus interface
Like the previous architectures, it can take a SCADA supervision system on Ethernet
or Modbus.
Redundant I/O on Modbus
In this type of architecture, the peripherals and devices are shared via the Modbus
link on which the Premium Primary and Standby PLCs are masters, with the other
peripherals or devices connected on the Modbus link as slaves.
The Premium PLCs each have the
7
TSX SCY 11601
or
TSX SCY 21601
communication module with their isolated RS 485 integrated link (25-way SUB-D
connector).
The cable connector
31
TSX SCA 50
placed on each Premium Primary and Standby
PLC includes the line terminator. In addition, since the
TSX SCY 11601/21601
communication modules polarize the Modbus line, disconnection of a slave during
operation does not in any way disturb Modbus communication.
