Ethernet network and TCP/IP Modem serial link
The distributed automation applications can use a unique communication network
which meet:
b The needs of real-time workshop performance.
b The open access requirements for the monitoring/commanding software based
upon products using standard communication protocols or applications using
Internet technology.
Ethernet and the point to point protocol (PPP) via serial link respond to different
requirements in terms of data rate, capacity for open access on TCP/IP and flexibility
in terms of topology.
Ethernet communication affects essentially the following applications:
b Co-ordination between programmable PLCs.
b Local or centralized supervision.
b Communication with production information management.
b Communication with remote inputs/outputs.
The various services offered are as follows:
b The TCP/IP protocol standard permits communication with:
v the Quantum platforms in the Modbus messaging, with the 140 NOE 771 pp
module,
v the M1E CPUs associated with the Momentum inputs/outputs I/O base in Modbus
messaging,
v the Premium platforms with TSX ETY 110 module (outside of Ethway profile) or
TSX ETY 410p/510p module,
v a PC terminal, which supports a standard browser for the Ethernet network,
v a PC terminal, with a modem which supports a standard browser for the serial link,
v all Uni-TE/Modbus TCP/IP devices (ATV 58 drive, Magelis terminals, etc.).
b The SNMP V1 network agent function. All Ethernet modules integrate the MIB II
standard (Management Information Base RFC 1213) and the Ethernet
Transparent Ready private MIB. These are compatible with the main network
administration software available on the market.
