Typical recording duration
Prerequisites for following tables:
• No limit value violation / integration
• Digital input not used
• Signal analysis 1: off, 2: day, 3: month, 4: year
• No active mathematics channels
Frequent entries in the event log reduce the memory availability!

The available storage capacity of the internal and external memory can be displayed
in the main menu under "Diagnostics → Device information → Memory
information" . The storage capacity depends on the specific device set-up.
