Does anyone have any recommendations or recent experiences for paperless/electronic replacements for traditional paper strip- or circular-chart recorders? The archives of this esteemed list have entries last dated Oct1998 on this topic.
I have several general needs:
Should be networkable, preferably through ethernet
Should be compatible with PLCs, and preferably able to communicate with them using ethernet or serially (mostly A-B protocols, but some MODBUS) Scalability is important, in two(2) ways:
number of points stored and ability to grow into an HMI (e.g. PanelView) replacement, with appropriate HW/SW upgrades
Standard input point types (4-20mA, 0-5 Volts, etc...)
I've started to check the standard vendors: Honeywell, Foxboro, Bailey...., but I seem to want more features than they can provide.
I'm hoping that someone has already done the legwork, and is willing to share.
Thanx in advance........Larry
