I'm new to C-More and am creating tags addressed to an S7-300 PLC. A few questions about the address scheme: 1. There is no PIW type. Will an IW get mapped to the PIW I have defined in the PLC? 2. There seems to be an IW limitation of not more than address 127. Is there any way to make this higher? 3. For the DB.DBW type, how do I specify the DB#? Thanks.

If you haven't already found it, try Topic CM482 in the C-more Help File.
1) C-more can not access the peripheral registers, you will have to use IW.
Not sure the URL will work, but try this:
http://support.automation.siemens.com/WW/llisapi.dll?func=cslib.csinfo&objId=24148871&load=treecontent?=en&siteid=cseus&aktprim=0&objaction=csview&extranet=standard&viewreg=WW
2) That looks correct by the helpfile: IW range 0-126
3) The helpfiile shows some examples:
Siemens, DB1.DBW2
C-more, Type: DB.DBW Address: 1.2
