Re: [foxboro] FDSI driver AB CSP or FDSI Driver Ethernet/IP

No, I'm sorry to say that .WM is not supported in CSP or DH+. Not having a 
system I can test it on, my "thought experiment" would lead me to try 2 PAKIN 
blocks, each reading consecutive 16-bit words with the /U2 option and PKIOPT=3 
to reverse the bits. Then connect those 2 PAKCIN's to II01 and II02 of a MCIN. 
The PAKCIN of the MCIN should be what your looking for. (My head hurts from 
trying to mentally work thru that.)

If you're trying to read I or O registers, try the same thing with IIN instead 
of PAKIN and connect the LIN's. (That may not work though, because I don't 
think /U2 works on I & O values.)

If none of that works, then brute force may be your only option ... reading 
32-bits with a PAKIN and mapping each bit in reverse order (1-16 into 16-1 and 
17-32 into 32-17) into a PAKOUT that is either configured to write to a "safe" 
register or is configured to a "dummy" ECB that is off-line. I think the values 
will still propogate, even though the block will show bad IO.

Good luck.

Brad,
That is what we need in all the AB FDSI drivers.  I saw that in the
EthernetIP manual you've referenced.  I don't see it documented for the CSP
or DH+ driver - can you confirm this is available in those?

Regards,

Kevin
