Actual tension data
Tension is read from the DLCA NET-ECAT in the four cyclic
parameters Tension 1, Tension 2, Tension Sum, and Tension
Difference.
The tension value is a 32-bit signed integer and is scaled to be 160
times the Maximum Tension value ignoring the decimal point
position set by parameter 0x207 or 0x217.
The tension reading will be at least 14-bit resolution when the
maximum tension is 3 significant digits. Lower resolution will
result if maximum tension is less than 3 significant digits.
In a One Tension Zone amplifier:
Tension 1 is the value of tension read on tension channel 1,
Tension 2 is the value of tension read on tension channel 2.
Tension Sum is the summation of the tension on channels 1 and 2
Tension Difference is the tension on channel 1 minus the tension
on channel 2.
In a Two Tension Zone amplifier:
Tension 1 is the value of tension read on tension channel 1.
Tension 2 is the value of tension read on tension channel 2.
The Tension Sum and Tension Difference are always 0.
