CS1 I/O Address Mapping

[Beryl 0]

Hello Everyone! For reasons beyond my control I need to change the default I/O address for the CIO in some my CS1's. What I need to be able to do, if possible, is to change the addressing for basic input and output cards to a different starting number. Example, slot #1 change to 2.xx instead of 1.xx. Make sense? Slot 0 is a 16pt output with addresses starting at 0.xx, slot 1 is a 16pt input and I want its address to be 2.xx, slot 2 is a 16pt output I want its address to be 1.xx and slot 3 is a 16pt input and I want its address to be 3.xx. I know, what the heck would I want to do that for? Because the people upstairs want it that way... Anyway I don't know if this is possible and I haven't found anything in the manuals that tells me if I can. I know I can start the addresses at whatever number but then they just increment on down the line. Any help or ideas would be appriciated. Thanks, Edited 9 Dec 2005 by Beryl

There are possibilities The first is the most expensive, move all the cards up one position and put a spare unused CIO I/O card in the first slot this will force all the CIO units up one. the 2nd i've never tried but it might work. within the I/O table for CS1 plc's there is the option for a dummy I/O selection again move the I/O cards up one and leave the I/O Slot 0 empty. within the I/O table select a dummy I/O module for the first slot. this will again move the I/O addresses up one.

I've just re read your post and realised i've gone off on the wrong tack. really all your trying to do is swap the I/O addresses of card 1 & card 2 over. Just swaping the card positions on the rack and updating the I/O table will achieve this.

Hello Beryl, You can edit the slot addresses in the IO Table component. Open IO Table, highlight the slot that you wish to re-address, use the Options menu and select 'Rack/Slot start addresses'. This gives you the ability to allocate a start address for individual slots in the IO Table. Hope this helps. Regards anonymous
