Devicenet SDN modules
(OP)
Hey,
Is there a valid status bit that can be used in the SDN card to detect an ADN adapter faults. Basically we have a system here that causes us trouble when a certain node fails, causing major line backups etc ... but if we were able to detect when this node faults we could disable the line ie. push it out of auto mode and prevent a product backlog from happening. Any help would be appreciated.
Cheers

What PLC are you using?
RE: Devicenet SDN modules
RE: Devicenet SDN modules
Can we post files to this site? I could E-mail too!
My assumptions are as follows:
scanner location, slot 3
M0 and M1 file lengths set to 361, check the advanced tab under I/O config.
The address where the data is stored is at M1 word 210.
your PLC code will read this and place it into integer files for program compairson.
Good Luck
XIC B3:5/0 OTE O:3.0/0 ; enables scanner
MOV M1:3.210 N7:1 ; Moves M1:3.210 to N7:1
MVM N7:1 00FFh N7:6 ; Mask Moves "00FFh mask" to N7:6, error code.
SWP #N7:1 1 ; flips the word, N7:1 around
MVM N7:1 00FFh N7:8 ; Mask Moves "00FFh mask" to N7:8, Device Address.
EQU N7:8 22 EQU N7:6 78 OTE O:1.0/0 ; A simple compare to give you the alarm.

But i dont think that if the adn module faults it is detected. It might of 2) and 3).
check the adn manual for the status word
