  • Offset - offset of value in the response(0..65535). For multibyte values, this is the offset of the first byte.
  • Type - 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 I/O tag of the TiA type, it is interpreted as a Unix times (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.

Examples of addresses:


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.
