I've been looking at other PLC controller offerings, and thus far the <http://www.digital-loggers.com/plchw.html> comes out ahead; it does a lot of what we need in a package with a good price. Alternatives I've found either cost far more or require lots of integration. (I've just been pointed at the Siemens Logo line and am looking into it now.) The Digital Logger has other things we don't need but we can ignore them. It does not have one important item, wired Ethernet. I'm pondering how that could be added outboard. What we need is really a terminal server: serial from the PLC on the one side, and TCP/IP on the other. You can buy such in a shiny box for say $100 <http://www.antaira.com/products/STE-501C?gclid=CIDYyKbRiNMCFdyEswod5E8AnQ> or less for boxless <http://www.mouser.com/ds/2/224/XPort_DS-220314.pdf> The latter requires making a PCB, worrying about power, etc. Any alternatives you're aware of? -- A host is a host from coast to coast.................wb8foz@nrk.com & no one will talk to a host that's close..........................
