• New machine parameter MP4030
Extension of the word marker range up to W1098
With MP 4030 = 1 you can switch to the new axis marker interface of the PLC. Here the new
words W1024 to W1060 are used instead of the previous markers.
If MP 4030 = 0 the markers are active as before and the new words from W1024 to W1060 can
then be used as desired.
The following PLC words are used when MP 4030 = 1 instead of the corresponding bit marker:

W1026 Axes into position (M2008...)
W1028 Reserved

• New PLC Module 9040
Module 9040 Read axis positions
Call:
PS
K/B/W/D Destination address (Dxxxx) for coordinate value of the first axis;
The coordinate values of the further axes are saved in the five following
double words;
PS K/B/W/D Coordinate type to be read 0..4
0: Actual value
1: Nominal value
2: Reference value
3: Following error
4: Distance-to-go
CM 9040
M3171 = 1 if error occurs during execution of the module
