NOTICE
Risk of material damage to the machine/plant!
A device cycle that is too short can have undesirable effects on the correct transmission of the
process and control data between the PLC and peripheral devices (higher-level PLC, AS-i slaves).
► Ensure a sufficiently long cycle time!
If the PLC is disabled, the device operates with a fixed cycle time of 0.7 ms.
If the PLC is enabled, the operator can set the device cycle to a value between 1.5 ms and
3.0 ms. (→ Enable/Disable the device-internal PLC (→ page 76))
