2.18 Group Codes
Note that the highest bit assigns the point to the cyclic data group. This data will
be cyclically reported to the Master at the frequency set in the configuration value
"Cyclic Data Transmission" Parameter.

0x00200000 Interrogated by group 4 counter request
0x40000000 Disable event scanning of this point
0x80000000 Periodic/cyclic data returned from unit
If the highest bit (bit 31) is set, data will be produced by the driver for the
specified point at the rate set for periodic data generation. Bit 30 (0x40000000)
enables scanning of this point for event generation. If the bit is clear and the data
type is set for scanning, events will be generated for the point. If the bit is set,
events will not be generated for the point. This feature can be used to select
which points will generate events for the controlling station and can get rid of
event data that is not important to the application
