Setting for General commands
(iv)
Using General command frame in the IEC 60870-5-103 standard, relay applications can be
performed by the remote control. For the GR200-series relay, a Data ID in the signal list is
controlled when receiving general command frame.
When the "General command" item is selected on the GR-TIEMS, the setting screen
is displayed.
Figure 10.4-7 "General command" setting screen
The frame of Type ID=20 (General command) and Command ACK/NACK can be set
in 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 check
the Ext check box, the setting of Command ACK/NACK is disabled and the Command ACK
and 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, see
In this setting screen, if a Data ID except "0" is set to "Sig Off" and "Sig On", the
command at INF setting value is provided and Command ACK or Command NACK is sent
back 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 and
no control is performed in the following cases:
(1):
When receiving any General command from the upper station before Command
ACK/NACK is sending back from the relay.
(2):
Under Monitor direction block condition ("IECBLK" setting is "blocked".) when
receiving 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:
