Modbus Plus network
The Modbus Plus network is a high-performance industrial local network which can
respond to Client/Server type extended architectures,combining a high data rate
(1 Mbit/s), simple and economical transmission support and several message
handling services.
The main data exchange functions between all devices connected to the network
are:
b The message exchange function according to the Modbus protocol.
b The “global database” function (Shared Table service, periodic, controlled by the
application: a station with the token can send 32 words to a maximum of 63 other
stations connected on the network).
1 The Premium (or TSX Micro) client communicates with the Quantum server on the
Modbus Plus network via function block (communication function).
2 The Quantum client communicates with the Premium server on the Modbus Plus
network via MSTR function blocks.
3 A Premium (or TSX Micro) client connected to the Ethernet TCP/IP or Fipway
network can communicate in read/write mode with a Modbus Plus station (the
Premium PLC therefore acts as a gateway).
4 A Premium (or TSX Micro) client connected to the Modbus Plus network can
access a remote station via the Modbus Plus/Modbus gateway.
5 A Premium client connected to the Modbus Plus network can make exchanges
with the Momentum distributed inputs/outputs via the Peer cop function.
