Input Parameters
Input parameter
Type
Description
ENABLE
BOOL
Start transferring.
ERT
BYTE
ERT type:
  • 0 = Quantum
  • 1 = Mx80
NOTE: When ERT type is:
  • Quantum: the time stamp is local time (UTC+TimeZone). The module converts local time into UTC and includes it in ERT reports. The time zone is set in the SNTP configuration window of the Modicon IEC61850 Configuration Tool.
  • Mx80: the time stamp is UTC time. No configuration is necessary.
EVT
Either:
Event description, including value, quality, time stamp and ID. Type depends upon the platform, either Mx80 or Quantum.
RPT
IED RPT
Report information.
TIMEOUT
INT
Time threshold in 100 ms for triggering an event. A value greater than 0.
Output Parameters
Output parameter
Type
Description
DONE
BOOL
A value of 1 (true) indicates the function block completed successfully.
ACTIVE
BOOL
A value of 1 (true) indicates execution of the function block is in progress.
ERROR
BOOL
A value of 1 (true) indicates the function block detects an execution error.
STATUS
INT
Identifies the detected error:
  • 1 = Input parameter is not valid.
  • 2 = <Reserved>
  • 3 = Time format is not valid.
    NOTE: Only dates after January 01, 2000 are valid.
  • 4 = Time out occurrence (default 10 s)
  • 5 = Parameter change during runtime
RPT_BUFF
IED ERT BUF
Raw buffer containing event time stamp entities.

Description
Status
WORD
Report status:
  • Bits 0...7: Report enabled/disabled. Each bit represents one report instance:
    • 0 = disabled
    • 1 = enabled
  • Bits 8...15: Buffer overflow:
    • 0 = No buffer overflow
    • 1 = Overflow
DaChgCnt
WORD
A counter value that increments each time a report is generated.

EvtSrc
BYTE
Event source:
  • 0 = Quantum
  • 1 = Mx80
EventEntity

Description
Rese1
BYTE
<Reserved>
Value
BYTE
Input value.
EventID
WORD
An event identifier, either:
  • The channel number; or
  • A user-defined value.
SecondSince Epoch
DWORD
The interval, in seconds, from 1970-01-01 00:00:00 UTC to the present.
FracOfSec_L
WORD
The fraction of the current second when the value element, above, has been determined. The fraction of second is calculated as:
(SUM from i = 0 to 23 of bi*2**–(i+1) s).
FracOfSec_H
BYTE
TimeQuality
BYTE
TimeQuality describes provides information regarding the sending IED, and consists of the following attributes:

Type
Description
0...4
Time Accuracy
CODED ENUM
The accuracy class of the time source. Only the value of 10 = 1 ms is supported.
5
Clock Not Synchronized
BOOL
When set to 1, this indicates the time source of the sending IED is not synchronized with external UTC time.
6
Clock Failure
BOOL
When set to 1, this indicates the time source of the sending IED is unreliable.
7
Leap Seconds Known
BOOL
When set to 1, this indicates that SecondSinceEpoch value includes all leap year seconds. When set to 0, this indicates leap seconds are not included and seconds are calculated from the current date assuming a constant day length of 86400 s.
