AddMe Lite includes all of the featuers of
AddMe III in a scaled down package. AddMe Lite features 12 universal
inputs. Two of the universal inputs support pulse counting,
either rate or totalizing. Two FET outputs may drive small DC
loads directly, or operate larger external relays.
Network variables for the analog I/O points may be confi gured for
any scalar LonMark SNVT, fi xed point or fl oating point. In addition,
analog (universal) inputs may be confi gured to SNVT_switch
with the on threshold programmed via the translation tables. Additional
56-point linearization tables are pre-programmed to convert
3K, 10K or 20K thermistors to SNVT_temp, SNVT_temp_p or
SNVT_temp_f.
The standard LonMark Object plug-in, or LonMaker browser, can
be used to do all necessary confi guration. Send times for network
traffi c throttling and heartbeat, send on delta, object override, etc.,
are all supported per LonMark standards.
AddMe Lite includes an RS-485 serial communications port in addition
to the LonWorks TP/FT-10 network port. AddMe Lite includes
a Modbus RTU Master. Up to 43 registers or objects may
be interfaced, each mapped to a bindable network variable. There
are 12 network input variables for writing Modbus registers, and
31 network output variables for reading Modbus registers.
