[foxboro] ABGateway, AW51 w/AB PLC, and MCIN blocks

Hey Everybody,

Long time no post!  (Which means things are good, I guess.)

I have run across an unusual problem and thought some of you might have 
already seen/solved it.

Here's the background...
I am building some displays for use with a lot of MCIN blocks coming from a 
ABGW30.  These FoxView displays lend themselves to using the BITSTATE 
parameters and OR ing several bits together for some fill colors. Typically 
I would do this with the PAKCIN parameter.  Of course, the bytes are 
reversed coming from the PLC unless you set the IOMOPT=3 of the MCIN.

Here's the problem...
We are using a simulator to test the displays/control before we put this 
into a production system.  The simulator uses a AW51 with Interchange to 
connect via ethernet to the PLC.  The PAKCIN seems to exhibit the same 
problem of having the bytes swapped, BUT I can't get the MCIN to accept an 
IOMOPT = 3 so I can't swap the bytes (easily, without using more 
blocks).  Has anyone seen this before?

Any advice would be appreciated.

Regards,
David Johnson
