| Az alállomások kommunikációjának fejlődése |
| The trend for substation communication is beginning
to migrate to Ethernet connections. Even today, many devices in power substations
use a serial interface to communicate with remote SCADA systems. Due to the
huge investment involved with substation communication systems and the necessity
for system reliability, the migration from traditional serial to Ethernet is an
issue for this market. Terminal servers connect serial devices directly to Ethernet
and are an excellent solution to current trends and evolving requirements. |

| Secure terminal server |
| To address EMI in substation environments,
most system integrators use fiber optic cable to replace Cat. 5 cable.
The NPort 6000 series provides 2 fiber optic Ethernet ports for
EMI noise immunity. In addition, the NPort 6000 series supports
802.3w RSTP (rapid spanning tree protocol) to connect two Ethernet ports
to different Ethernet switches. One Ethernet port can be configured as a
primary path and the other as a back-up path. If the primary path is damaged,
the NPort 6000 will activate the back-up connection immediately to ensure zero
data loss during communication. |

| Dual LAN terminál szerver |
| A CN2650 2 Ethernet portot tartalmaz különböző
MAC címekkel, amelyeket
can be configured to send copies of the same serial data over
different routes. Dual LANs provide enhanced system reliability without data loss. |
|
| Advanced Modbus átjáró |
| A Modbus egy standard kommunikációs protokoll
ipari eszközök (PLC-k, HMI-k, mérőeszközök, driverek) között.
Az MGate MB3000 termékek segítségével a Modbus RTU/ASCII eszközökkel könnyedén
csatlakozhatunk Ethernet hálózaton keresztül HMI/SCADA rendszerekhez.
