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

I/O tag types: Ai, Ci, Qi, Di, TiA, Co.
The address of the I/O tag can have different forms.
...
- EmNr - electrometer number in EM structure (1..255). The total number of electrometers that the concentrator sends must be set in the Number of EMs protocol parameter.
- EmParam - measurement parameter: CA|CA1|CA15|OV|PV|PV1|PV15|PPO
- CA - Instant value of the counter (0..9_9999_9999)
- CA1 - Instant value of the counter (0..9_9999_9999) at the end of 1-minute interval
- CA15 - Instant value of the counter (0..9_9999_9999) at the end of 15-minute interval
- OV - Instant power [kW, kVAr]
- PV - Average power since the beginning of current 15-minute interval [kW, kVAr]
- PV1 - Average power at the end of the 1-minute interval [kW, kVAr]
- PV15 - Average power at the end of the 15-minute interval [kW, kVAr]
- PPO - Electrometer's data validity (a 16-bit number specifying the number of seconds)
Examples of addresses:
...
- WrNr - ordinal number of word address (1..255) within a response
- BitNr - bit number (0..15)
- DiParam - parameter INP|PPO
- INP - binary value (digital input)
- PPO - data validity (a 16-bit number specifying the number of seconds)
Examples of addresses:
...
For instant values of 16-bit counters - read from the object with address Actual Data Object ID - it has the form EW.EwNr where:
- EwNr - ordinal number of the counter (1..255) within a response. The total number of counters that the concentrator sends must be set in the Number of word counters protocol parameter.
...
- Offset - offset of value in the response(0..65535). For multibyte values, this is the offset of the first byte.
- Type - the type of value. The following types are supported:
- BYTE - 1-byte unsigned number
- SBYTE - 1-byte signed number
- WORD - 2-byte unsigned number
- SWORD - 1-byte signed number
- DWORD - 4-byte unsigned number
- SDWORD - 4-byte signed number
- FLOAT - 4-byte float number
- DFLOAT - 8-byte float number
Note: if the DFLOAT value type is configured on the I/O tag of the TiA type, it is interpreted as a Unix times time (number of seconds since January 1, 1970, in UTC)
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.
