Supported device types and versions
The protocol supports reading data from the Remia KME concentrator. Internal number of REMIA protocol is 206.
The protocol supports reading of instant values as well as 1 and 15 minute archives of measurements from electrometers, which KME obtains:
- via IEC communication
- by measuring pulses
The protocol also supports reading of instant values of binary data and values of 16-bit counters.
The protocol also supports reading of generic instant values (I/O tags with GA address) and reading of records from event log archives (I/O tags with RECNR address).

- Communication line category: TCP/IP-UDP.
- Parameters of TCP/IP-UDP line:
- Host: IP address of KME concentrator
- Port: UDP port of the concentrator where requests are send (default port is 5001).
Communication station configuration
- Communication protocol: Remia KME.
- Station address is not specified.

RTD - 4-byte timestamp (2 bytes hours/minutes/day, 2 bytes month/year)
- BitNr - optional bit number for values of BYTE (0-7) and WORD (0-15) types, if the values are assigned to I/O tags of Di type.

GA.6.BYTE
An object with a Generic Event Object ID address is used to access events from the event log. For reading, a Co type I/O tag with a RECNR address is required. Writing an integer value into it will read the event with the corresponding record number from the event log. The format of the read data is application dependent (depending on the configuration of the Remia KME concentrator). The number of the most recent (or next) record in the event log can usually be obtained by reading a block with generic instant values. Writing of value into I/O tag with a RECNR address is finished after the read data have been inserted into defined input I/O tags.
