Model 574 Programmable Counting System (PCS)
210 - GSE Scale Systems
15 PRINT ERRS:
a. <ENTER> key alone:
The "Print Errs" command is very similar to the "Print
DBASE" command except that only rows whose data is
suspect are printed. A report format is used which causes
multiple rows to line up well on a printout. After
pressing the <ENTER> key on this selection, the
prompt: "1 for Comm" followed soon by "2 for Prntr"
will appear. Press the <1> key to send the transmission
out the bi-directional communications port or press the
<2> key to use the uni-directional printer port. Pressing
any other key will abort the transmission. The "Print
errs" command should only be used when problems are
suspected in the stored data. This command could also
be used periodically to check for problems in the stored
data. The resulting tranmsission will begin with the
header line (column names), followed by any rows which
were found to be corrupt, followed by a summary
indicating the number of rows which were found to be
corrupt compared to the total number of rows found.
Also if a bad link is detected in the list of rows, then that
error is also reported (refer to the Errors section for more
details on the "Bad Link" error). At the end of the
transmission a form feed character (^L) is sent.
Each row that is stored away is accompanied by a
checksum which is used to verify the integrity of the
stored data. Every time a row is accessed, its integrity is
checked by re-calculating the checksum. If the
checksum is found to be incorrect, an error is displayed
warning the operator of this condition. Once a row is
updated, the checksum is recalculated.
b. An entry followed by the <ENTER> key:
A <1> or <2> may precede the <ENTER> key for the
"Print errs" command in order to specify the port to be
used, <1> for the communication port or <2> for the
printer port . This form of the "Print errs" command
simply bypasses the prompting for the operator to key in
a particular port number.
16 UPLOAD NEW:
a. <ENTER> key alone:
The "Upld. new" command allows the uploading of new
rows of data into the 550's database through the bi-
directional RS-232 communication port. After pressing
the <ENTER> key on this selection, the unit will begin
reading in rows of data from the comm port. During the
upload, the 574 will display a counter indicating the
number of rows which have been created. Pressing the
<CLR> key will abort the process. This should not
normally be done until the tranmsission has first been
halted at the source. In the absence of a <CLR> key, the
574 will continue processing data until a "^Z" (DOS end-
of-file character) is received. The format required for the
data is a comma delimited ASCII format, with a carriage
return and optional line feed after each row. This format
is compatible with the instrument's "Down-load"
database command. Backed-up databases may be easily
reloaded into the Indicator using this selection
The "Upld. new" command can be very useful for
restoring 'backed up' databases. Also, for applications
where the database required to be stored in the Indicator
is available on another computer, this command allows
the loading of that information quite simply.
NOTE: Use of a computer communication program,
such as Scale-Link or Procomm or GSE 550 Simulation
Software Terminal Window (on an IBM or compatible
PC), is required on your computer to send and receive
files to and from the unit.
b. An entry followed by the <ENTER> key:
An entry is not allowed before the <ENTER> key for
this selection. If an entry occurs, the "ENTRY ERROR"
message will be displayed briefly.
17 UPLOAD UPDATE:
a. <ENTER> key alone:
The "Upld. Updat" command allows the uploading of
new rows or the updating of existing row of data in the
instrument's database through the bi-directional RS-232
communication port. After pressing the <ENTER> key
on this selection, the unit will begin reading in rows of
data from the comm port. During the upload, the unit
will display a counter indicating the number of rows
which have been created. Pressing the <CLR> key will
abort the process. This should not normally be done until
the tranmsission has first been halted at the source. In
the absence of a <CLR> key, the unit will continue
processing data until a "^Z" (DOS end- of-file character)
is received. The format required for the data is a comma
delimited ASCII format, with a carriage return and
optional line feed after each row. This format is
compatible with the unit's "Down-load" database
command. Thus backed up databases may be easily
reloaded into the unit using this selection
