Retention It is a requirement of system and machine controllers for
operating states or actual values to have retentive settings.
What this means is that the values will be retained safely
even after the supply voltage to a machine or system has
been switched off and are also retained until the next time
the actual value is overwritten.
The following operands and function blocks can be set to
operate retentively:
•Markers
• Counter function blocks,
• Data function blocks and
• Timing relays.
