Data Byte #2-#5 Pulse value per volume or time unit, depending on PulseType value, IEEE 754. Meaningful
only for ìPulse/Volumeî or ìPulse/Timeî settings of PulseType. The related unit is based on
Primary Variable Unit.
For more details refer to the previous section, 8.11.
CAUTION: PulseWidth should be changed only if the PulseType value is requested either as ìPulse/Volumeî or as
ìPulse/Timeî!
NOTE: The requested PulseWidth value will be set to the nearest possible value within allowed set {5, 10, 20, 50}. If
necessary, PulseValue will be set to the nearest possible value for a given PulseWidth. Master will be prompted about
PulseValue corrections via warning-type response codes.

CODE
Data Byte #0 The function of the status binary output:
0 - All Errors,
1 - Fatal Error,
2 - Off,
3 - On,
4 - Forward/Reverse Indication,
5 - Tripping Point.
Data Byte #1-#2 Tripping point, unsigned integer, in 1/100% of the Primary Variable Upper Range Value
(say, 5% will result in a value of 500 on a bus). The responded value is actually used by the
instrument only when Data Byte #0 is set to ìTripping Pointî.
