What is the reason for this code? 6 years 9 months ago #1189

I am currently working on 2 smart motors daisy chained with rs-232 communication. I found this code at the beginning of their programs. From my understanding the motors with this type of communication automatically address themselves on start-up, unless the CAN address is already stored in the memory. I am just trying to understand the reasoning behind coding it this way.

Motor #2

ADDR=2
CADDR=2
CANCTL(2,1)
ECHO
EIGN(W,0)

Motor #1

ADDR=1
CADDR=1
CANCTL(2,1)
ECHO
EIGN(W,0)

Thanks for your help.

ADDR=2 'SET RS232 AND RS485 ADDRESS CADDR=2 'SET COMBITRONIC, CANOPEN, DEVICENET, OR PROFIBUS ADDRESS CANCTL(2,1) 'IGNORE THE ABSENCE OF 24VDC ON CAN PORT ECHO 'ECHO COMMAND SENT BACK TO HOST EIGN(W,0) 'SET ALL 5VDC I/O TO GENERAL PURPOSE INPUTS
