eWON is able to perform local data acquisition by using its serial or its Ethernet port. The data acquisition process is designed around a TAGs database in which each tag is associated to an IO SERVER.

Available IO Servers are:

  • MODBUS RTU
  • MODBUS TCP
  • UNITELWAY
  • NETMPI
  • DF1
  • EWON
  • MEMORY

(see IO server documentation for more details - eWON User Manual)

The tag reference will be used for Alarm Management, Data logging and other Remote Managements features.
