Never come across this kind of problem..
I'm setting up new system, and I/O:s are already been decided.
There is only one 32 bit 24vdc input card, and one 32bit 24vdc output card.
Input area should start from 1 to 4, and output area from 1 to 4 too.
System will be also added 4 inverters, but that's not the problem, those are not even configurated at the moment.
At hardware configuration, input cards default values would be from 0-3, and output card from 4-7.
With this configuration system would maybe work.
But when I change inputs and outputs area to 1-4, for some reason some of bits from output byte 1 are "ON" state, when cpu starts...
And I do not have even OB1 yet..
Is there some interrupt or something at 315-2DP, which writes to output byte 1?
If I try to reset these bits from VAT-table, they remains at state "1".
Also first three bits from output byte 2 are not changeable.
Or am I just too tired..
