Also, you will need to determine the following regarding the client
’
s network:
Maintenance times for the network (shutdown of the network)
Network utilisation (Load > 30
–
40 % is bad on shared network)
Collision rate (< 5% is good)
Stability of the network (> 99.9% is good)
Availability of the network (Downtime)
Access time to the network (timeouts / access time < 1 sec. is good)
Responsibility for the data transfer over the network
Building sites (dredgers destroy cables, etc.)
Redundancy of the network
UPS (uninterruptible power supply) for the network components?

Information you need to give to your customer
To integrate FS NK8000 and management station products into a customer
’
s network,
ensure that your customer is aware of the following information:
DHCP is not supported from any device;
NK822x supports only Half-duplex and 10 Mbps;
Only Ethernet RJ 45 copper cable Cat. 5, 5E, or 6 is supported;
If the network is down, it is not possible to receive any information via the network;
The responsible person for the network is the customer, and not Siemens
FS/FIS/SES. The customer should sign a contract that Siemens FS/SES disclaims
any liability for the customer
’
s existing network.
Your customer will also need to know the following:
The IP-address for each NK822x and each DMS PC (tell where the devices are in-
stalled);
Redundancy network devices or paths available.
5.3.2
Security and Application Port numbers
Most companies use a Firewall or a Proxy server to protect the company network from
outside. Also within a company
’
s network, rules exist, and not everything is allowed.
For example, maybe only e-mail and File transfer applications are allowed, and Re-
mote access (Telnet) is prohibited.
Each of these applications has a Port number. This Port number identifies the type of
application. For example the Port number for the e-mail application (SMTP) is 25.
Generally, the network administrator allows only a few Port numbers, and the rest are
prohibited.
The following Port numbers are used by NK8000:
–
TCP Port number 3001 (NK822x)
–
TCP Port number 3001
…
3004 in multiple host configurations
–
TCP Ports 20 and 21 (FTP for the configuration download to NK822x)
–
TCP Port 4000 for service messages
–
UDP Port 47808 (hex BAC0) is default for BACnet connectivity, but is configur-
able
The network administrator must allow these Port numbers; otherwise our applica-
tion is prohibited in the network.
Note: More TCP/IP ports may be needed for MM8000/MK8000.
For details, see the MM8000 Sales Guide (STEP #A6V10062427).
