I'll start out by describing my hardware setup so as to paint a more descriptive picture. I have a desktop running RSLinx. This desktop connects to another machine running RSLinx as a gateway. The gateway machine is connected to a Data Highway Communication Inferface, also known as a 1770-KF2. This KF2 connects to a SLC500. I can connect to my SLC500 with my desktop via the gateway just fine. I have an Excel spreadsheet on my desktop that connects via a topic on my local copy of RSLinx to the PLC. This spreadsheet both displays data, ie integer values, and edits those integer values in the PLC, using a VB applet. The purpose of the spreadsheet is so that the values in the PLC can be directly editted without opening RSLogix. The issue here is that in order to use the spreadsheet, I have to be running RSLinx on my desktop. What I would like to do is connect the spreadsheet to the PLC without using RSLinx on my own machine, possibly by connecting directly to the gateway machine's RSLinx. All OS's are Win2k, and all copies of RSLinx are Pro. If this is possible, please post some info or links that I can follow for publically available info. Also, I'm a college intern, and I don't have a whole lot of experience using PLC's and connection protocols in particular, so try to be detailed.
Thanks in advance, Chris
