Photograph or write down the four-character display and RUN, FORCE, SD, OK and network indicator states. That evidence often separates project, storage, network and hardware conditions that may disappear after a restart.

No; memory size and safety integrity level are different properties. The catalog remains rated for SIL 2/PLd Category 3, and a higher required level needs a suitable certified architecture.

Check whether an SD card was inserted, removed or used for a store/load operation and compare the controller setting with site procedure. Do not load an unknown image into a safety controller; verify project identity and signature first.

Those are maximum capacity figures, but the real project must also satisfy power, connections, memory, update-rate and safety reaction-time requirements. Complete all capacity checks instead of assuming each maximum is independently guaranteed under every workload.

Safety connections add identity, timing and signature expectations beyond basic reachability. Inspect device keying, safety network numbers, requested packet intervals, topology recovery and the safety I/O diagnostics.

Review the FORCE indicator and controller force state, remove unintended forces and verify the resulting machine behavior under controlled conditions. A successful download does not prove that commissioning forces were cleared.
