Example 1:
80175-01
Retrieve the direct values from a 3300 rack which contains a vibration monitor in slot 4
and a 6-channel temperature monitor in slot 5.
The vibration monitor has two values associated with it, channel one vibration and
channel two vibration. The temperature monitor has 6 temperature values associated with
it. The request message should have a starting register of 6 and request 8 values
(registers).
Example 2:
Read the direct values from a 3300 rack which has dual vibration monitors installed into
monitor positions 1 and 2 and a 6-channel temperature monitor in monitor position 5.
The data that we want consists of 10 values contained in nonsequential locations starting
at word address 0. To retrieve the data most efficiently we should request the entire 14
value block which will include the values for the empty monitor positions 3 and 4. The
host should then throw out the invalid data from monitor slots 3 and 4. The Read Input
Registers query message will specify the start register as 0 and the number of registers
as 14.
Example 3:
Read the temperature values from a 6-channel temperature monitor in slot 5 of a 3300
rack. This rack also has a 6-channel temperature monitor in slot 1 and 2 dual vibration
monitors in slots 3 and 4.
The starting register address for the temperature monitor in slot 5 is 10. This is the
temperature for channel 1. Channels 2 through 6 follow at addresses 11 through 15. The
Read Input Registers query message will specify the start register as 10 and the number
of registers as 6.
