Retain variables and persistent variables can only be declared in
a "Global Persistent Variable List" which belongs to an applica‐
tion. Only one such list can be added per application.
Persistent variables are only reinitialized in case the control unit is
reset.
The functionality of the retain variables and persistent variables is
described in the "IndraLogic 2G, PLC Programming System" doc‐
umentation:
PERSISTENT)".
● Symbols
The number of symbols depends on where the boot project is stored.
– Boot project in parameters:
With MPB and MPC firmware, up to approx. 2,000 symbol varia‐
bles are possible depending on the data type when the boot project
is stored in parameters; this requires no programmed code and on‐
ly symbol variables declared. The more code the application con‐
tains, the smaller the maximum possible number of symbol varia‐
bles.
– Boot project on MicroSD card:
Compared to storing the boot project in parameters, with MPC firm‐
ware many more symbol variables are possible when the boot proj‐
ect is stored on the MicroSD card, because the code memory sets
the limit. The following example can be used as a guideline in prac‐
tice: 10,000 symbol variables require approx. 1.5 MB of code mem‐
ory.
● Parameters for general purpose
– 32-bit parameters
– 32 buffered parameters (P-0-1316 to P-0-1331 and P-0-1370
to P-0-1385)
– 32 unbuffered parameters (P-0-1270 to P-0-1301)
– 32-bit list parameters
– "P-0-1368, PLC Global Register AL0" (list register with 8,192
values, unbuffered)
– "P-0-1389, PLC Global Register GL0" (list register with 1,024
values, buffered)
– "P-0-1311, PLC Global Register GL1" (list register with 1,024
values, buffered)
– "P-0-1312, PLC Global Register GL2" (list register with 1,024
values, buffered)
– Two global text registers with 255 characters each
– Display format of the parameters for general purpose can be para‐
meterized via "P-0-1386, PLC display format Global Register"
– Name, unit and limit values of the parameters for general purpose
can be configured via PLC functions
● Process input image (PII) (max. 72 bytes)
