Application manual
Example 1:
AnalogXRange =
3277.0
IECEQUATION2446 V1 EN-US
The scale factor is calculated as follows:
´
(3277.0 2.0 )
=
sc alefactor
65535.0
IECEQUATION2447 V1 EN-US
The scale factor will be sent as 1 on configuration frame 2, and 0.1 on
configuration frame 3. The range of analog values that can be transmitted in this
case is -0.1 to -3276.8 and +0.1 to +3276.7.
Example 2:
AnalogXRange =
4915.5
IECEQUATION2448 V1 EN-US
The scale factor is calculated as follows:
´
(4915.5 2.0 )
=
sc alefac tor
65535.0
IECEQUATION2449 V1 EN-US
The scale factor will be sent as 1 on configuration frame 2, and 0.15 on
configuration frame 3. The range of analog values that can be transmitted in this
case is -0.15 to -4915.5 and +0.15 to +4915.5.
Example 3:
Analo gXRange =
10000000000
IECEQUATION2450 V1 EN-US
The scale factor is calculated as follows:
(10000000000 2.0)
=
sc alefac tor
65535.5
IECEQUATION2451 V1 EN-US
The scale factor will be sent as 3051804 on configuration frame 2, and 305180.43
on configuration frame 3. The range of analog values that can be transmitted in this
case is -305181 to -10000000000 and +305181 to +10000000000.
