Table 5-4 Allocation of DS 15
5.5.1 DS 15 – Tare Entry
DS 15 is used for external specification of the tare weight. Once specified with DS
15, the tare value is not yet activated. The transfer to SIWAREX MS tare memory
is then done using command “Accept tare entry” (see command code
24
). The
specified tare value is rounded to the numeral step set in the parameters. The
rounded tare value is output in DS 30.
If the tare weight is defined through the controller then the transfer is not done
through data record DS15, it is done through the variable range. See chapter
8
.
5.6 DS 26 Internal Process Values
DS 26 is used to store the current internal process values. These values can be
read, saved and written back to the SIWAREX MS. However, you may not change
the values. Procedures:
o
Read the values.
o
Send the values to SIWAREX MS as required (after replacing modules)
(Not
possible if the wire bridge in on terminal P-PR)
