5-104 C60 BREAKER PROTECTION SYSTEM – INSTRUCTION MANUALPRODUCT SETUP CHAPTER 5: SETTINGS5The UR implementation of IEC 60870-5-103 consists of the following functions:• Report binary inputs• Report analog values (measurands)• Commands• Time synchronizationThe RS485 port supports IEC 60870-5-103.The UR Family Communications Guide contains more information on the protocol.IEC103 COMMON ADDRESS OF ASDU — This setting uniquely defines this C60 on the serial line. Select an ID between 0 and254. This ID does not need to be in sequential order for all stations that communicate with a controller, but it isrecommended. Note that RS485 only allows a maximum of 32 slave stations on a communication line, so the entire rangeof 254 addresses is never exhausted.IEC103 SYNC TIMEOUT — This setting defines the time that the C60 waits for a synchronization message. The C60synchronizes 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 C60 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.
