Hi all,
Summary
I am stuck at what I hope is the last step (see below) in trying to look at [Data Views] via a MicroLogix built-in web server. I have been able to Google'n'guess my way this far but not over that last step; it looks like some of you have done this before, so any advice would be appreciated.
Update
It's javascript, right?
Hmm, maybe not; I found this in http://172.16.240.240/TableList.js:

I bought my first PLC, a [1763-L16BBB Series B Rev B FRN 7.0], from eBay. I built my own DB9/DIN-8 RS-232 cable. l have been fiddling with it point-to-point over both RS-232/DF1 and Ethernet, put some simple programs on it, flipped input bits and watched output bits change; I put tape over the DC COMmon terminals so I won't put my +24VDC test wire in there again (should have used a resistor;-). Hearing the relays clicking is much more satisfying than the emulator.
When the first HTTP attempt at FRN 7.0 suggested doing so, I installed ControlFLASH and upgraded the firmware to FRN 16 (and found out that cannot be done via Ethernet).
Now I am trying to look at the data using the built-in web server while the unit is in [REMOTE RUN] mode. I am trying to see if scraping its web server pages is easier than writing a custom service e.g. using AdvancedHMI.
I can ping the ML100.
With Chrome, I can open the home web page, and change the administrator and guest passwords on the [User Management] page. But when I go/switch to the [Data Views] page/frame, I get this:
It appears Chrome is trying to protect me there, and I have not yet found out how to get around Chrome's cautious nature.
That's okay, because Internet Explorer is more willing than Chrome to lower its pants, and I got to here for [Data Views]:
and to here for [New Data View]:
There are so many little things to learn that this industry is starting to look like a secret society; I think I need just one more.
That's as far as I got. Thanks in advance for any suggestions.
