We use an Allen Bradley PLC along with an industrial road-mapped Windows XP pc which in turn runs a Citec Scarda package we need to
be able to communicate with these remotely to enable program changes and general monitoring.
Each time we complete are process a unique file is created logging time date water temp chemical strength flow rates pressures etc. We would like to collect these files or have them sent on demand back to head office.
We are and have been using a Westermo GDW-11 GSM modem "dial up" which has served us well with contracted data sim cards
Having use these for some 15 years when they we "rocket science" we now need to up our game and find out whats available and from whom and at what cost?
With our upcoming trials & expansion in to New Zealand we need a reliable link to
my equipment which means I can put a programmer on the web?? rather than on a plane!!
