For the GR200-series relay, a Data ID in the signal list iscontrolled when receiving general command frame.When the “General command” item is selected on the GR-TIEMS, the setting screenis displayed.Figure 10.4-7 “General command” setting screenThe frame of Type ID=20 (General command) and Command ACK/NACK can be setin this screen. In one command of General command, the INF, FUN and DCO must be set.The Command ACK/NACK is for detail setting and must not be set usually. (If do not checkthe Ext check box, the setting of Command ACK/NACK is disabled and the Command ACKand Command NACK respond according to the default response.)The maximum 32 frames of General command and Command ACK/NACK can be set.The information number of the frame is determined by the INF setting. The most left item“No.” is only serial number and can be skipped.Common address is linked with the address setting† of the relay.†For more information, seeAppendix: IEC 60870-5-103 interoperability.In this setting screen, if a Data ID except “0” is set to “Sig Off” and “Sig On”, thecommand at INF setting value is provided and Command ACK or Command NACK is sentback when receiving the command from upper station. If both “Sig Off” and “Sig On” have“0”, the fixed length NACK is always sent back then and the command is not provided.Though the command is provided, however, Command NACK is always sent back andno control is performed in the following cases:(1): When receiving any General command from the upper station before CommandACK/NACK is sending back from the relay.(2): Under Monitor direction block condition (“IECBLK” setting is “blocked”.) whenreceiving General command.(3): When receiving an incorrect value of DCO of General command, that is DCO is neither“1” nor “2”.General command receiving sequence is as follows:
