Table 10- 6 Scale commands
1101 Start single
Starts an individual dosing cycle.
1103 Start continuous
mode
Starts n dosing cycles in continuous succession Continuous operation
ends automatically if a total set point (DR 21) was specified and reached
or alternatively using the "Stop continuous mode (1123)" command. If a
dosing cycle is still active, it is completed. The "Abort weighing (1124)"
command also ends continuous operation but does not terminate an
active dosing cycle.
The "Continuous mode active" bit in the AWI Status (DR 30) indicates
whether or not WP251 is operating in continuous mode.
1121 Stop weighing Current dosing cycle is stopped and the "Weighing cycle stopped" bit is
set in the AWI Status (DR 30). The "Continue weighing (1141)" command
can be used to continue and thus complete the cycle from this status.
1122 Activate check
stop
If check stop points have been defined (see section I/O interface of func-
tion block (Page 191
)), these are activated by "Activate check stop" and
the dosing cycle stops at the predefined points.
1123 Stop continuous
mode
Continuous operation is stopped. If the command is issued within a dos-
ing cycle, this dosing cycle is first finished and WP251 then waits in
weighing step 0. The "Continuous mode active" bit in the AWI Status (DR
1124 Abort weighing The current dosing cycle is directly aborted and WP251 jumps immedi-
ately to weighing step 0.
1125 Rest weighing The command can be issued within the dosing cycle or outside of it
(=weighing step 0). Any active coarse or fine signal is directly reset, a
tolerance check is performed, a log print is created and – if configured in
DR 25 –the scale is emptied. WP251 then waits in weighing step 0.
1126 Manual emptying
ON
The command can be issued only in weighing step 0. The "Emptying
signal" bit is then set to TRUE and a linked digital output, if any, is set.
The command is used to clean the scale or to open it manually for ser-
