SEL-2020 Instruction Manual
TOGGLE m (Access Level 2)
The TOGGLE command toggles the specified element (parameter m) for test purposes. You may
specify global elements simply by giving their name. Local elements must have the port number
preceding the element label (i.e., 4:D2). If that element can trigger an operation, then that opera-
tion will occur. Use this command to test your data collection and data access functions without
having to force some external condition.
Normally, the toggled element will automatically toggle back as a result of subsequent SEL
OGIC
Control Equation calculations. However, if the specified bit has an unused SEL
OGIC
Control
Equation, it will remain in the new state until you use the TOGGLE command to return it to the
original state. The TOGGLE command is intended for test purposes only; you should use the
CONTROL command if you want operational control of some bits.
VIEW (Access Level 1)
Use the VIEW command to look at data stored in a port’s database. The data are displayed as
formatted data if accessed by data region, as hexadecimal words if accessed by address, or as
binary value if accessed by bit. Supply the following parameters after the VIEW command in the
order listed:
data reference Use any valid data region (port number, region label, or data type label),
register address, or bit access method to specify the data to be viewed.
Examples:
VIEW 1:D1 (port #:region label)
VIEW 1:METER (port #:data type label)
VIEW 1:0807h (port #:register address)
VIEW 1:0807h:4 (port #:register address:bit number)
C Add the clear flag after a BUF or archive region reference to clear that
region as you view it.
Example: VIEW 1:BUF C
CAUTION
!
Frequent archive record clearing may exceed EEPROM
capabilities. See the discussion in the Archive Data Region
subsection of
Section 9: Database .
BL Add the bit label flag after a region reference to see any elements in that
region displayed as bits with their labels. Such elements exist in the
GLOBAL, LOCAL, and TARGET (if not in archive) regions.
Example: VIEW 1:GLOBAL BL
/n Add a number “n” after an archive region reference to see that record
number within the archive record queue. Number 1 is the oldest record,
higher numbers reference newer records.
Example: VIEW 1:A3/4
Note: You cannot use the clear parameter C with /n, i.e., you can only
clear the oldest record.
