Establishing A Network Connection; Ip Addresses - Pfeiffer Vacuum PrismaPro QMG 250 Translation Of The Original

Procedure
► Connect a gauge to the <TP GAUGE> connection of the PrismaPro.
► After replacing a gauge, disconnect the power supply plug of the electronic unit for 10 seconds
5.6 Establishing a network connection
The PrismaPro uses Ethernet as standard communication method and has an IP address and a MAC
address.
● IP addresses
● MAC addresses
PV MassSpec uses IP addresses to localize and identify PrismaPro systems in a network. You can find
information on some general network variables that may influence the PrismaPro connection in the fol-
lowing sections.
5.6.1 IP addresses
IP address conflicts when using multiple PrismaPro devices
Pfeiffer Vacuum supplies each PrismaPro with the same default IP address. Simultaneous connec-
tion of multiple PrismaPro devices with the same IP address leads to IP address conflicts in the net-
work.
1. Change the IP addresses of the PrismaPro devices being connected.
2. Connect the PrismaPro devices to a network.
Standard IP address of the PrismaPro
● Network prefix: 192.168.x.xxx
● IP address: 192.168.1.100
– The electronic unit detects the gauge type automatically when it is switched on.
and then plug it in again.
– The electronic unit reads in the new gauge type.
A network uses IP addresses as a means of identifying individual units. IP addresses are unique
in a network but are not universal which means that only one device in a network can have a cer-
tain IP address, but two devices in a separate network can have the same IP address.
MAC addresses are another identification that is unique for each device. MAC addresses are sin-
gular.
Using IP addresses
Pfeiffer Vacuum recommends the use of static IP addresses.
Reserve a block of IP addresses for static use and ensure that these reserved IP address-
es are prohibited on the DHCP server (host). This will prevent any conflicts with double IP
addresses.
If you connect the PrismaPro to an existing local network, a static IP address is required for
each PrismaPro installed. Consult your network administrator for assigning the IP address-
es.
Static IP addresses protect against the loss of data
The PV MassSpec software uses the IP address of the PrismaPro to identify each connect-
ed PrismaPro. The IP address of the PrismaPro may not be changed during operation.
With DHCP, the host can generate a new IP address each time if the PrismaPro goes off-
line and back online again. DHCP can also automatically change the IP address if there is
an IP address conflict in the network. If the PrismaPro IP address changes randomly during
data acquisition, PV MassSpec does not automatically reconnect with the PrismaPro as PV
MassSpec does not recognize the newly assigned IP address. This leads to the loss of
communication and the loss of data.
Static IP addresses only change when the IP address is changed manually, and help to
protect the PrismaPro against loss of communication and data.
