Please help! Omron c40k

I want to say Thank you evrebody who helped me a lot in my previous topiks. One more question. I use syswin 3.4 to programm Plc.And I met very strange thing. PLC hase inputs numbered from 0000 to 0207 two of them 0000-0001 24VDC the rest-120vac.So when I am trying to put in adress symbol editor input 0200 the syswin automaticly confers it like 002 which is already exist. Why?
Thank you!

Which PLC?

I have never used Syswin but since I see you online right now I will try and help. I suggest using a decimal point.

ex: 2.00

:site: And how is it going?

When using Syswin, The bit of a channel is separated from the channel number with a decimal point. On the C40K PLC, you have two (2) Input Channels. They are 00 and 01. You also have two (2) output channels. They are 02 and 03. The bits within these channels are designated in the Syswin software using the decimal point as a delimiter. Therefore, the input bits are 00.00, 00.01, 00.02 etc. through 01.07. (24 input bits) the output bits are designated in the same fashion. 02.00, 02.01, 02.02 etc. through 02.11. and then 03.00, 03.01, 03.02, and finally, 03.03 for a total of 16 output bits.

I hope this makes it clear for you.
