4.5 Multiple PPCI7443 Cards Operation
The software function library support maximum up to 12 PPCI7443 Cards,
that means maximum up to 48 axes of motors can be controlled. Since
PPCI7443 has the characteristic of Plug-and-Play, users do not have to
care about setting the Based address and IRQ level of cards. They are
automatically assigned by the BIOS of system when booting up. Users can
utilize PPCI7443 Utility to check if the plugged PPCI7443 cards are
successfully installed and see the Base address and IRQ level assigned by
BIOS.
One thing needed to be noticed by users is to identify the card number of
PPCI7443 when multiple cards are applied. The card number of one
PPCI7443 depends on the locations on the PCI slots. They are numbered
either from left to right or right to left on the PCI slots. These card numbers
will effect the corresponding axis number on the cards. And the axis number
is the first argument
for most functions called in the library. So it is
important to identify the axis number before writing application programs.
For example, if 3 PPCI7443 cards are plugged in the PCI slots. Then the
corresponding axis number on each card will be:
Axis No.
Card No.
Axis 1
Axis 2
Axis 3
Axis 4
1
0
1
2
3
2
4
5
6
7
3
8
9
10
11
If we want to accelerate Axis 3 of Card2 from 0 to 10000pps in 0.5sec for
Constant Velocity Mode operation. The axis number should be 6. The code
on the program will be:
_7443_start_tv_move(6, 0, 10000, 0.5);
To determine the right card number, Try and Error may be necessary before
application. PPCI7443 Utility can be utilized to minimize the search time.
For applications needed to move many axes simultaneously on multiple
PCI_7443 cards, users should follow the connection diagrams in Section
3.12 to make connections between their CN4 connectors. Several functions
illustrated in Section 6.8 may be useful when writing programs for such
applications.
