vipa cpu200 and i/o's

hi all,
i have a problem with a vipa cpu 200. i designed a new system with an old vipa, bur it doesn't recognise i/o's after 127.
when i try to download a function as:

a i128.0
=q0.0

i get a download error, but with i127.0, there's no problem.
and the plc's old program has some i/o's after 127 (140,160 etc)
so i can not understand this situation.

do you have an idea?

Are you limited to Octal addresses only? Try 130 as the next address. (Change all addresses that have an 8 or 9 in them).

VIPAs are similar to Siemens, aren't they? All of the Siemens CPU's I've worked with have a limit on the number of bytes you can address directly (i.e. I127.0). For an older 315-2DP processor it was 128 bytes (IB0 through IB127). It would not let you use an address like I128.0, I127.7 was OK, but I128.0 was not.

In Siemens,if the processor only supported 128 input bytes (0 through 127), byte 128 has to be addressed as a peripheral input byte, PIB128, which you cannot directly access the individual bits of. You can move PIB128 to say MB128 (using a MOVE command in ladder or load and transfers in STL) in the program and then use M128.0, M128.1, ....



Edit:
Nevermind, I didn't read at first that larger addresses had worked in the old program in the same processor.

do you know any siemens cpu that does support larger than 127.0?
forexample does a cpu313 or cpu 315 can do it?

317, 319 both have larger images and can be stretched. The latest 315-2PN/DP CPU can be stretched passed 128 (V2.5). I like doing this and then all my I/O is scan with the OB1 cycle. Easier to force and I don't get a diagnostic access fault every scan when I have missing I/O.
