Basic Configuration Attributes
134 Power Line Frequency (FREQ) ........................................................................................C – R
Power Line Frequency is used by certain I/O modules for proper noise rejection. The valid
values are:
50 0 The frequency of the ac input power to the instrument is 50 hertz.
60 1 The frequency of the ac input power to the instrument is 60 hertz.
135 User Tag (USRTAG) .......................................................................................................... CWR
A user tag with up to 27 configurable or readable ASCII characters that identifies the
instrument (25 can only be written). This is a standard ASCII data type, with the number of
valid characters stored in the first byte of the field. Field size is always 28 bytes.
136 Configurator Tag (CFGTAG) ............................................................................................ – – R
Up to 27 ASCII characters generated automatically as a time stamp by the configurator. This
is a standard ASCII data type, with the number of valid characters stored in the first byte of the
field. Field size is always 28 bytes.
137 Database Size (DBSIZE).................................................................................................... – – R
Size of the database in bytes.
138 I/O Mismatch (IOMM) ........................................................................................................ – – R
YES 1 An I/O mismatch exists in the database.
NO 0 No I/O mismatch exists in the database.
General Instrument Status Attributes
139 Instrument State (INSTATE) ............................................................................................. – – R
Identifies the current instrument state.
UPLOAD 0 Instrument was powered up with memory module switch in the
upload position and will do nothing beyond copying the main
database (if it is 'complete' and its checksums verify) into the
memory module.
DEFAULT 2 The instrument does not have a valid user generated database
and is therefore running a default database to sustain
communications, etc.
BEING CONFIGURED 3 An external device has configuration control and is authorized to
download. The instrument is running the default database in
expectation of downloads to the main.
HOLD 4 The instrument has a valid user database, but is running only
overhead blocks. (No loops).
LOCAL HOLD 5 Instrument has a valid user database and would be in RUN but
is prevented by the run_hold_switch and is running only
overhead blocks.
RUN 6 Instrument has a valid user database and is running all blocks.
