DeviceNet Module Parameters

B-7

Sets the mask of the 16-bit Logic Status word. Unless they are
masked out, the bits in the Logic Status word are checked for
changes when the module is allocated using COS (change of state).
If a bit changes, it is reported as a change in the change of state
operation. If the mask bit is 0 (Off), the bit is ignored. If the mask bit
is 1 (On), the bit is checked.

Important: The bit definitions in the Logic Status word depend on

the drive.

Sets the hysteresis band to determine how much the Feedback
word can change before it is reported as a change in the COS
(change of state) operation.

Displays the amount of time that a scanner will wait to check for
data in the module.

When COS (change of state) data exchange has been set up, this is
the maximum amount of time between scans. Scans will happen
sooner if data changes. When Cyclic data exchange has been set
up, this interval is the fixed time between scans. This interval is the
heartbeat rate configured in the scanner.
