Bit sequence: V2
In this bit string, 16 variables of type BOOLEAN are represented in two
octets.
Code: 115
dec
= 73
hex
Time constant: D2
Values of time data type D2 always refer to a specific, constant scan time T
a
.
This time Ta is the shortest scan time (defined in PNU 962) and is required
here in order to evaluate D2.
The value for D2 can be calculated as follows:
D2 = i x T
a
/16384
Time constant: T2
Values of time data type T2 are always relative to a specific constant scan
time T
a
. T
a
is the shortest scan time (defined in PNU 962). It is required here
to calculate T2.
The following formula applies: T2 = i x T
