For example, if register 30021 contains the value “0x0123” and register 30022 contains
the value “0x4567”, the total reject count is calculated as follows.
Register
value Mathematical
expression
Numeric
value
0x0123 0 x 16
7
= 0
0x4567 +1 x 16
6
= 16,777,216
+2 x 16
5
= 2,097,152
+3 x 16
4
= 196,608
+4 x 16
3
= 16,384
+5 x 16
2
= 1,280
+6 x 16
1
= 96
+7 x 16
0
= 7
Total = 19,088,743
This, clearly, is an unrealistically high total reject count, but illustrates how register
values are used to assign a numeric value for the total number of rejects.
Resetting Statistics
To reset the following APEX statistics, set parameter-change coil 16386 to one (1). This
resets the following APEX statistics—and the appropriate Modbus registers listed below—
to zero (0).
•
Total reject count
• Quality Assurance Test count
• AuditCheck count
• Total pack count
Resetting Peak Values
To reset the APEX peak values, set parameter-change coil 16388 to one (1). This resets
the current peak value to zero (0).
Backing Up Critical APEX Settings
Backing up critical APEX data is important, because it provides insurance against
catastrophic system failures. Backing up your data does not take up a lot of space. The
amount of disk space needed to back up a single product, for example, is only 808
bytes, as shown in the table below.
NVRAM allocation Space used (bytes)
DSP configuration 96
HMI configuration 388
Single-product configuration 324
Total = 808
