Channel
EXECUTION

SYNTAX
Cchans,
type
[,
[lowsp],
[highsp],
[hyst] ]
Configure the channels for the master unit and its slave units.
chans
and
type
are required arguments, while
lowsp
,
highsp
and
hyst
are
optional.
chans
may be in two forms:
chan
(for a single channel where
1
<
chan
<
max
) or
first-last
(for a range of channels where
1
<
first
<
last
<
max
), where
max
= 128 for NetScan.
The chassis is
chan = 0
.
type
is the type to assign to those channels.
C?
Query current channel configuration.
DESCRIPTION
The optional arguments
lowsp
,
highsp
and
hyst
are the low setpoint, high setpoint and hysteresis values,
respectively, for the Configure Channels (
C
) command. These arguments are only needed if it is desired to
configure alarms on the specified channel(s). The format for these optional arguments follow the rules for
readings input defined under the Set Data Format (
F
) command.
The channel
type
is used by the unit to determine how a certain channels readings are to be interpreted.
Because of this fact, defining the channel type is critical to the proper configuration of the channel. Each channel
must be assigned a channel type in order for it to be included in the scan group. Likewise, assigning a channel
type of
0
will remove that channel from the scan group.
The following table outlines the channel types for NetScan.

The following list outlines the channel type definitions:
Null Type: The null channel type is type
0
. Assigning a channel to the null type will remove the channel from
the scan group.
Thermocouple Card Types: See the following tables for details.
Volts Card Types: See the following tables for details.
High-Voltage Card Types: See the following tables for details.
Reserved Types: Reserved types are types that are reserved to the internal processes of the unit. Among
these types,
90
and
91
are reserved for chassis calibration. Refer to Chapter 6 for calibration details.
