3-Design The next table gives parameter definitions: TS_NTP_DFB Input No Parameter Type Comment 1 Input TS_DDT_Input TS_DDT_Input.module (BYTE): inputs module number TS_DDT_Input.in (ARRAY[1..16] OF BOOL): 16 discrete inputs 2 Mode INT mode=1: TS with input Rising edge detection mode=2: TS with input Falling edge detection mode=3: TS with both Rising and Falling edge detection 3 Ack BOOL Acknowledgement of the new TS A Rising edge of Ack can trigger an acknowledgment of one TS. If Ack is set to 1, a new TS is always acknowledge. 4 Reset BOOL error reset, buffer reset Output No Parameter Type Comment 1 NTP_time Display_NTPC Display_NTPC.DT_Value: real RTC time and data Display_NTPC.Millisecond: real RTC ms 2 nd_ts BOOL nd_ts=1: New TS in the buffer nd_ts=0: The buffer is empty 3 Ts TS Time stamping struct: TS.in (WORD): D0~D5: the channel number of the discrete input D6, D7: the mode of the input. (01: Rising edge, 10: Falling edge.) D8~12: the module number of the input signal. TS.ms (WORD): ms part of the time stamp TS.hour_min (WORD): hour and minute part of the time stamp (BCD type) TS.month_day (WORD): month and day part of the time stamp (BCD type) TS.year (WORD): year part of the time stamp. (BCD type) 4 Status WORD The status of the DFB. The DFB has a TS buffer which can store up to 100 TS data. The data is stored in the buffer until the Ack is set to 1. D0~D7: Quantity of new TS in the DFB buffer D8: Buffer status 0 = Buffer empty 1 = Buffer overloaded 2 = Buffer not empty nor overloaded 30
3-Design DFB3: TS_ERT Function: The TS_ERT DFB is designed for reformatting ERT mode time stamps. It receives the time stamps and transforms the data to a format that can be received by SCADA. This DFB also handles a buffer that can store up to100 records of time stamped data. Data type: • DFB type: TS_ERT • DFB input/output types: 31
