SCAN
Description: Lists the present value and alarm status of each channel.
Command Level: 1
Syntax: SCAN [channel_type] [channel_designator] [channel_range] [node_designator]
[node_range] [group_designator] [search_text]
S [channel_type] [channel_designator] [channel_range] [node_designator]
[node_range] [group_designator] [search_text]
Comments: Analog and Function Channel information displayed includes the current
value of each input, the unit of measure, and any of the alarm limits that are active and
the alarm class of these limits.
Binary Channel information includes the contact status, open (CO) or closed (CC), the
alarm status, and the alarm class.
Relay Channel information consists of the on or off status, the relay force status, the
alarm status, and the alarm class.
Energy Management Channel information consists of a description of the rectifier,
capacity, shunt value, and the RFA and TR status.
LED Channel information consists of the on or off status, the LED force status, the alarm
status, and the alarm class.
If desired, only certain channel types can be viewed by entering the command SCAN
followed by a space and then the character A for analog, B for binary, L for LED, F for
function, G for group, R for relay, or E for energy management. A continuous scan of a
single input is possible by adding the input number after the A, B, L, F, G, R, or E
character. Press the Ctrl-S key to stop scrolling, and use any other key to continue.
The user can set the time interval between scan data output lines when scanning an
individual channel. The interval can be specified from 1 to 600 seconds. This is done by
entering a modifier (1 through 600) at the end of a scan command line. If no modifier is
entered, a single line of scan data is displayed. (ex. SCAN A12 20, would output one line
of scan data for analog channel A12 every 20 seconds.)
Notes: Analog and binary channels are automatically mapped to MCA parameters when
the VPS or LPS MCA Interface is used. Status information for these analog and binary
channels can be viewed using the SCAN command and options. Refer to Tables 2-1
through 2-3 for a correlation between channels and mapped VPS MCA and LPS MCA
parameters. To view status information of just the VPS, use the SCAN VORTEX
command and options. This command is explained next.
