9.5.9 Reading Setpoints

Direct parameterization (PB 11)
By means of input 14.1, the initial setpoint for track 4 can be read; input 14.2 gives the end setpoint.
Both setpoints are shown in the flag double words FD 138 and FD 142. By setting input signal 14.7
or 15.0, the zero shift for channel 1 or 2 stored in the module can be assigned to flag double word
FD 150 or FD 154. With the programmer function "control variable" this looks as follows:
KH = 00000225
FD 134
FW 132 KH = 0000000000010000
FD 138 KH = 00000200
FD 142 KH = 00000300
KH = 80000250
FD 150
KH = 00000000
FD 154
If inputs 14.0,14.1, and 14.2 are permanently on, the changing of the actual value, the identifier bits
and the track setpoints for track 4 can be observed directly on the viewing screen.
Indirect parameterization (FB 11)
The assignment for triggering the setpoint output to inputs 14.0, 14.1, 14.2, 14.7 and 15.0 corre-
sponds to that for direct parameterization. With the exception of the track identifier bits, all set-
points and actual values are stored in data double word DD 3 in working data block DB 158. Data
word DW 5 indicates information concerning the track identifier bits of channel 1.
In contrast to direct parameterization, only one setpoint or actual value can be monitored in data
double word DD 3 of working data block DB 158.
9.5.10 Modifying Setpoints for Track 4
The setpoints for track 4 are contained in user data block DB 156 in the data words DW 30 through
DW 34. In order to supply these with new values easily, the screen display of the programmer can
be expanded as follows:
DB 156
DW 30 KH – 0000
KH – 00000200
KH – 00000300
Now the new setpoints in the module can be monitored as shown below based on the type of
