Miscellaneous Command Descriptions
HELP Command
The HELP (H) command provides general information on command syntax and functionality when the
manual is not available. Entering HELP or H provides information about using the HELP command.
HELP1 or H1 returns a complete list of relay commands. Entering HELP <cmd> where <cmd> is a
specific command, returns information about the use and format of the command along with an example
of how the command is used.
HELP Command
Purpose: Obtain help on command operation
Syntax: HELP {cmd} or H {cmd} for help on {cmd}, H1 for command list
Example: HELP, H1, H SG-COM
ACCESS Command
Before making settings changes through a communication port, the ACCESS command must be used to
obtain programming access. Enter ACCESS=<password> to obtain access to change settings associated
with the password. Different passwords give the ability or access to perform different operations. The
relay will deny access if an invalid password is entered or if another user has already been granted
programming access through another serial port or at the front panel. Only one user can have access at
any one time.
Even if password protection is not used, it is still necessary to obtain access so that accidental changes
are prevented. If password protection is disabled, then ACCESS= will be accepted in place of a
password. The relay will respond with ACCESS GRANTED: GLOBAL if the command entered was
received and executed. The relay will respond with an error message and a question mark (?) if the
command could not be executed.
The ACCESS (A) command and the EXIT (E) command are used to change relay settings, reset report
registers, and enable control commands through a serial port. These commands prevent changes from
being made concurrently from two areas. For example, a user cannot make changes through COM0 at
the same time a remote user is making changes through COM2.
ACCESS Command
Purpose: Read/Set Access level in order to change settings
Syntax: ACCESS[={password}]
Example: ACCESS=851
Comments: The ACCESS command must be used before any changes to settings can be made.
Available ACCESS privileges are summarized in the following paragraphs.
READ-ONLY. This is the default access privilege when no passwords are active. Read-only access
allows you to read settings and reports but not make settings changes.
PRIVILEGE G: GLOBAL ACCESS. Global access is obtained by password G (PWG). Global access
permits entry of any command with no restrictions.
PRIVILEGE S: SETTING ACCESS. Setting access is obtained by password S (PWS). Setting access
allows changes to any settings.
PRIVILEGE C: CONTROL ACCESS. Control access is obtained by password C (PWC). Control access
enables relay control operations.
PRIVILEGE R: REPORT ACCESS. Report access is obtained by password R (PWR). Report access
enables report operations to be performed.
An access privilege is obtained only when the appropriate password is entered. When a valid password is
entered, the relay responds with the access privilege provided by the password entered. If an invalid
password is entered, an error message is returned. If password protection is disabled in one or more
privileges, then entering any string will provide access to the unprotected privileges.
