Sequence
Setting of the counting direction
M = Master Status-/Control bits Data bits
S = Slave
Bit 31 30 29 28 27 26 25 24 23 22 21 20 19 18 17 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0
M-->S
0 0 0 1 0 0 0
The selected counting direction is changed over from 0 to 1 or 1 to 0 using bit 28
S-->M
0 0 0 0 / 1 0 / 1 0 1
The measuring system now acknowledges the newly selected counting direction in bit 0 and 28
0 / 1
M-->S
0 0 0 0 0 0 0
Changeover is completed by setting bit 28 to 0
S-->M
0 0 0 0 / 1 0 / 1 0 1
The process actual value is now output again
Preset adjustment
M = Master Status-/Control bits Data bits
S = Slave
Bit 31 30 29 28 27 26 25 24 23 22 21 20 19 18 17 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0
M-->S

Here the preset value is transferred as desired new actual value
S-->M
0 0 0 0 0 0 0
The measuring system acknowledges the takeover in bit 7 of the status byte
M-->S
0 0 0 0 0 0 0
By setting the bit 31 to 0, the adjustment is finished
S-->M
0 0 0 0 0 0 0
The process actual value is now output again

TR-Mode Position TR-Mode PVelocity 87, 88
TR-Mode High Resolution TR-Mode High ResVelocity 90, 91
The number of diagnosis bytes can be restricted from 6+51 bytes to 6+10 bytes with
this parameter, such that the measuring system can also be operated with older
PROFIBUS master releases.
