Commands; Command Groups - Siemens SIWAREX FTC Device Manual

6 Commands

6.1 Command Groups

The SIWAREX command are divided into groups. The combining of the commands
into a group is done according to their functionalities.
Every command has a unique number. A command can be sent via various
interfaces (SIMATIC, SIWATOOL FTC, digital input).
Every time that a command is sent to SIWAREX FTC, a check must be made for
whether the command has been executed correctly. The data and operating errors
(synchronous errors) that are generated provide information on why the command
could not be executed.
The Service and adjustment commands group is used during the
commissioning of the scale. As long as the scale is not adjusted, it can only be
used in service operation. Switching to service operation is indicated in the status
bits.
The group of scale commands NAWI (non automatic weighing instrument)
contains all instructions that concern the handling of a static scale. Normally,
commands that have anything to do with the operation of the SIWAREX FTC as a
non-automatic weighing instrument (e.g. zero setting, taring).
The group of display commands contain all commands that are used for
switching the content of the main display.
The extensive group of Belt Scale commands is used for controlling the belt
scale. The basic behaviour of the SIWAREX FTC is defined one time by defining
parameters.
The group of log commands contains commands that control the log output to a
printer or the verifiable storage of the logs.
Use of the Micro Memory Card MMC is controlled with commands from the
command group Micro Memory commands.
After receiving a command, SIWAREX FTC checks for whether the command can
be executed. If the check results are negative, the user is informed of the cause by
an output of a "synchronous" message (see chapter
Diagnosis
6-88 SIWAREX FTC
).
