Have beginner knowledge of digital controls, and intermediate/advanced knowledge of socket clients and listeners (written logging proxies, socket automation with cookies/headers, etc).
Allen Bradley PLC, with "1769-L30ER" and "A LOGIX5330ER". PLC coder has added a boolean, and a counter that resuls from the boolean.
What is the simplest way to extract that boolean and counter value, from a linux CLI (preferably client).
Web server running on plc :80 shows pages of data, yet all system/network, no stored data. If we could get it from there, wget would take seconds.
snmp is running, yet again... only system/network info. Again, if we could get the data there, snmpwalk would take seconds to write.
Or, is there a simple way to open a socket on the plc, submit a get of some sort, receive a socket return, then hang up... open, send request to get boolean value, receive boolean value, close?
Are there any perl modules (such as with ftp, etc), that would permit a simple open, submit, receive, close?
Thx!
