5-78 C70 CAPACITOR BANK PROTECTION AND CONTROL SYSTEM – INSTRUCTION MANUALPRODUCT SETUP CHAPTER 5: SETTINGS5IEC103 SYNC TIMEOUT — This setting defines the time that the C70 waits for a synchronization message. The C70synchronizes its clock using all available sources, with the source synching more frequently overwriting the time of theother sources. Since the synchronization message received from the IEC 60870-5-103 master is less frequent than IRIG-B,PTP, or SNTP, its time is overwritten by these three sources, if any of them is active. If the synchronization timeout occursand none of IRIG-B, PTP, or SNTP is active, the C70 sets the invalid bit in the time stamp of a time-tagged message.The settings for the remaining menus are outlined as follows.SETTINGS PRODUCT SETUP COMMUNICATIONS IEC 60870-5-103 IEC103 INPUTS BINARYThe binary input points are mapped using elements from a list of possible FlexLogic operands. A maximum of 96 binaryinputs (points) can be mapped this way.The IEC 60870-5-103 point list always starts with point 0 and ends at the first "Off" value. Since the IEC 60870-5-103 pointlist must be in a continuous block, any points assigned after the first "Off" point are ignored.For each defined point, set appropriate values for the Function Type (FUN) and Information Number (INF), which form theInformation Object Identifier field of the ASDU, as defined in IEC 60870-5-103.The binary input points are sent as Class 1 data. They are sent either as a response to a general interrogation receivedfrom the controller or reported spontaneously. Spontaneous transmission occurs as a response to cyclic Class 2 requests.If the C70 wants to transmit Class 1 data at that time, it demands access for Class 1 data transmission (ACD=1 in thecontrol field of the response).SETTINGS PRODUCT SETUP COMMUNICATIONS IEC 60870-5-103 IEC103 INPUTS MEASURANDS IEC103 INPUTS BINARY POINT 0See below POINT 1See below POINT 95See below POINT 0 POINT 0 FUN0Range: 0 to 255 in steps of 1 POINT 0 INF0Range: 0 to 255 in steps of 1 POINT 0 InputOffRange: FlexLogic operand POINT 95 POINT 95 FUN0Range: 0 to 255 in steps of 1 POINT 95 INF0Range: 0 to 255 in steps of 1 POINT 95 InputOffRange: FlexLogic operand IEC103 INPUTS MEASURANDS ASDU 1See below ASDU 4
