2.7.6 Serial address
The DGF supports the Slink3 and Slink4 multi-point protocols. The DGF can
communicate via its own serial line as well by the drive serial line. When the DGF
communicates through its own serial line you must address it by its own address,
parameter ADDRESS(511) . When the DGF communicates through the drive serial
line you must address it by drive address, setting the option field at 2. When you link
2 or more nodes together you must specify different addresses for each node. You must
set the ADDRESS parameter (511) to the desired address. It will be copied into parameter
ACT_ADDR(3).
2.7.7 DP-RAM
You must configure the interface with the drive. Parameter EN_DPRAM(299) enables/
disables the DPRAM. If enabled, you must configure the parameters of the drive you
want to modify. Parameters 100 to 149 specify the direction of the parameter (IE means
from the DGF to drive, EI means from the drive to DGF) and their priority (SYN
means high priority, ASYN means low priority). You must set the index of the drive
parameter you want to access. The drive parameter will be accessed by the period.
When the period is not executed (the DGF is in READY status) the value of the written
parameters are set to 0. You can avoid this by setting the appropriate bits in the IE_SAVE
parameter (297). Usually these parameters are not set through DBASE but with the
programming tools.
2.7.8 I/O configuration
It is possible an hardware configuration directly by the DGF. This includes DGF
LEDs H1, H2, H3 and H4 and some test points and all the possible I/O cards.
To configure on-board DGF hardware use the parameter CW_CPU(300). For normal
operation set this parameter to the default value. If you need one or more of the resources
of the DGF reset the corresponding bit in the in CW_CPU and use then with the
appropriate brick.
To configure the additional hardware there are 4 sets of parameters: ID_CARD 1,2,3
and 4(301, 303, 305, 307) and the corresponding CW_CARD 1,2,3 and 4 (302, 304,
306, 308). You must set the identifier of the additional card in the ID_CARD parameter
and the configuration of the hardware in CW_CARD. Refer to the applicable card
documentation for more information.
