Problem with PLCSIM s7-300

whenever i connect factory io to plcsim from the drivers tap, and try to modify a memory word via the PLCsim, it doesn’t let me do it
i have to go to TIA Portal and change the value manually
here’s a video of what’s happening

Hey there, this seems to be a problem between PLCsim and TIA Portal.
Can’t really help you there as we don’t work with PLCsim, even though we use Siemens a lot.
