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:
FD 134
KH = 00000225
(actual value)
FW 132
KH = 0000000000010000
(track identifier bit 4 set)
FD 138
KH = 00000200
(initial setpoint track 4)
FD 142
KH = 00000300
(end setpoint track 4)
FD 150
KH = 80000250
(zero shift, channel 1)
FD 154
KH = 00000000
(zero shift, channel 2)
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
(User data block)
DW 30
KH – 0000
(Interrupt preelection)
DD 31
KH – 00000200
(initial setpoint)
DD 33
KH – 00000300
(End setpoint)
Now the new setpoints in the module can be monitored as shown below based on the type of
parameterization selected.
