7.13 Retention function
7.13 Retention function
Only possible with easySoft 7.
It is a requirement of system and machine controllers for operating states or ACTUAL
values to have retentive settings. What this means is that the values will be retained
until the next time the ACTUAL value is overwritten.
There are two input fields (for the start and end values of the retention range) each for
markers and for the following function blocks.
Project view/ System settings tab
Figure 226: Screenshot of Retention section that can be found in the System settings tab in the Project
view (including sample values)
Value range for the function blocks, instances that can be stored retentively:
l
C - Counter relay : 01…32
l
CH - High-speed counter : 01…04
l
CI - Incremental counter : 01…02
l
DB - Data function block : 01…32
l
T - Timing relay : 01…32
For more information, please refer to the description for the relevant function block.
Marker value ranges:
l
MB : 1 …512
l
MW : 1…512
l
MD : 1…256
The values from the input field will be automatically converted to MB marker bytes.
Retention bytes
The entire retentive marker range for an easyE4 must not exceed 400 bytes. The total of
the retention bytes for the main program and user function blocks (UF) will be displayed
in the Project view, in the System settings tab. If the retentive marker range exceeds
400 bytes, a red negative number will be shown in the Free field in order to indicate this.
