Run_DeviceNet
Run_DeviceNet
exchanges data with the DeviceNet Slave.
Syntax
#Include ADwinGoldII.Inc
ret_val = Run_DeviceNet ( out_pd_arr [],
out_pd_arr_len , in_pd_arr [], in_pd_arr_len ,
work_arr [])
Parameters
Notes
Run_DeviceNet
should be processed in a program section with low
priority, because of the long processing time. Using the instruction in a
(non-interruptable) high priority process, the communication between
PC and
ADwin system would be interrupted too long and thus produce
an error message (timeout).
Each array element in
in_pd_arr []
and
out_pd_arr []
contains a
single data byte only (bits 0…7). Data areas of more than one byte
length are saved in the appropriate number of consecutive array ele-
ments. Example: 5 data areas of 4 byte length are stored in 5
×
4=20 ar-
ray elements.
Valid for
Gold II-DeviceNet
