MODEM A device which allows digital data (as opposed to voice) to be
transmitted between two sites, usually via public telephone lines. In the case of
a Verbatim autodialer equipped with the CDL or SCADA option, a modem is
built into the option card so that no external modem is required.
NETWORK The physical and higher level protocols for a specific vendor’s
PLC data communications. The Verbatim can support a maximum of 3 net-
works simultaneously. The actual number of networks and type of protocol are
hardware options.
NETWORK ADDRESS
The concatenation of the network ID, node, and
PLC address. It is sometimes symbolized by ‘/net/node/addr’ where net is the
network ID, node is the node address, and addr is the PLC address. The network
address suffices to uniquely identify any data object which the Verbatim can
access.
NETWORK ID
A voice message identifying a specific network. By
default, the message is "Verbatim Net X", where 'X' is a number from 0 to 5.
Custom messages, such as "Building 320 LAN" may be recorded. See
'NETWORK' entries below for more details.
NETWORK 0
Refers to the discrete, analog, and RSC points internal to the
VSS.
NETWORK 1 Refers to devices connected to the 'NET1' port on the serial
communications card. Protocols may vary.
NETWORK 2 Refers to devices connected to the 'NET2' port on the serial
communications card. Protocols may vary.
NETWORK 3
Refers to devices connected to the MBPLUS port on the
MBPLUS communications coprocessing card.
NETWORK 4 Refers to devices connected to the Parallel port.
NETWORK 5
Refers to devices connected to the Modem port on the serial
communications card.
NODE The address of a specific PLC on the network. Each PLC is already
configured with a unique integer as its node address. The Verbatim must also be
given a unique number as its node address on each network to which it inter-
faces. The network ID and node together suffice to uniquely identify any PLC.
NORMAL CONDITION For contact closure inputs, the Normal Condition
is that condition (open or Closed Circuit) which normally exists. The opposite
condition would create an alarm. See Section 3.3, “Programming Input Chan-
nels” and 5.3, “Receiving Alarm Calls.”
