Hi,
Can someone explain to me the following?
I’m using the CP0484 PLC, which has 2GB of memory available.
If I go to Physical view → PLC → configuration → pv memory, I can configure 4GB of PVs.
How does the PLC handle this?
I always raise the values slightly if they fall out their range, but I’m not sure if this is the right way?
shouldn’t this be limited to 2GB and why do I have to modify this myself?
thanks in advance
Hello,
the X20CP0484 has various memory types onboard.
2 GB Flash
256 MB DRAM
64 KB FRAM (non-volatile)
The volatile variables share the DRAM with all modules loaded from the flash, e.g., the operating system, driver, or application.
I would initially keep the default value for the variable memory. If it’s not enough, you can always increase it.

Stephan
Hi Stephan,
Thank you for your reply.
what i still don’t understand is that i can configure 4gb but only have 2 available.
