What happens?
The following error message appears in the message window when loading a PLC project with RETAIN variables:
Download failed. Insufficient memory capacity on device.
Logging in to the controller is no longer possible.
When does the problem occur?
The above-described response may occur after repeatedly downloading PLC projects with RETAIN variables.
Which products are concerned?
PLC Designer V3.0 and higher
Possible diagnostics:
None
Short-term measures/recommendations:
Execute 'Remove all' on the 'Device (Controller 3200)>Applications' tab. Execute the menu command Build>Clean all.
Assessment:
After repeated project downloads, downloading may fail if fail-safe variables are used in the PLC project. The above-described recommendation is a workaround for this function restriction.
