Line Coupler, MDRC LK/S 3.1, GH Q R0001

Transcription

1 , GH Q The coupler can be used as a line The coupler is installed in the distribution board on the data rail of the coupler or a backbone coupler. CDC 07 0 F000 As a line coupler, it links a line with a main line. As a backbone coupler, it links a main line with the backbone line. It thus ensures electrical isolation. Telegrams can be filtered at the same time. It is possible to route only those telegrams that are intended for the other line. For diagnostics purposes, all the telegrams can be routed or disabled. secondary line. The main line is plugged onto the bus connecting terminal on the top of the device. Device replacement: When replacing an LK/S. with a new line coupler, only the file LK_Dummy.vd needs to be imported into ETS. In this case, the old parameters of the line coupler (and the old application) can be loaded into the new line coupler.

3 , GH Q /backbone coupler.0 /backbone coupler With the parameter Check filter table, it is possible to switch this checking Selection in ETS ABB System components Coupler The coupler links two lines for data transfer but isolates them electrically. If the coupler receives telegrams (for example during the commissioning of an EIB installation) which use a physical address as a target address, it compares the physical addresses of the sender and receiver with its own physical address and then decides whether it must route the telegrams or not. If the coupler has not yet received its own physical address, it can cause faults when commissioning other devices. The coupler reacts to telegrams with group addresses in accordance with its parameter settings. function on or off. When the checking function is activated, the parameter On error in filter table determines the reaction of the coupler. So that any errors are detected as quickly as possible, the setting block can be selected. In the default setting route, the installation will generally operate without any problems for the user. In installations with a high volume of telegrams, there could be time delays. There is no space for main groups 4 and 5 in the filter table. They should therefore normally not be configured. If they are used however, the parameter Main group 4/5 must be set to route. During normal operation (default setting), the coupler only routes the telegrams whose group addresses have been entered in its filter table. Particularly during commissioning and for diagnostics purposes, it may be a good idea to set the first two parameters Group telegrams main line -> line and Group telegrams line -> main line to route. If the EIB installation then functions without any errors after the commissioning of the sensors and actuators, the ETS program can calculate the correct filter table (in the Project Design module via the Filter button). The two parameters can now be reset to the default values again. The application must then be reprogrammed (in the Commissioning module). The correct filter table is then transferred into the coupler. If the coupler routes a telegram and does not receive an acknowledgement or if a bus device establishes a transmission error, the coupler repeats the telegrams up to three times. With the parameters epetitions if errors, this behaviour can be set separately for both lines. This can be advisable if the couplers are operating without filter tables in an installation and are routing all the telegrams. The bus load can be reduced in this case. These parameters should be left in the default setting. Normally, the coupler only acknowledges the telegrams that it routes. With the parameters Telegram confirmation, it can be set separately for both lines that the coupler acknowledges each telegram. These parameters should also be left in the default setting. When programming the filter table, a check sum is determined which the coupler uses during continuous operation to establish whether the filter table has changed. Page of 6 LKS TD_EN_V-0 CDC D00

5 , GH Q epeater.0 repeater If an error occurs during the transmission of a telegram with the physical Selection in ETS ABB System components Coupler A coupler can also be used as a line repeater. In its function as a repeater, it links two line segments for data transfer but isolates them electrically. Up to three line repeaters can be used behind a line coupler. As a result, up to four line segments can form a complete line. The line repeaters do not have any filter tables. This means that a telegram is sent to all line segments, whether it is processed in the corresponding line segment or not. It is therefore not important whether the telegram has been triggered within the lines or whether it has been sent from the main line to the lines via the line coupler. If the line repeater receives telegrams for example during the commissioning of an EIB installation, which use a physical address as a target address, it compares the physical addresses of the sender and receiver with its own physical address and then decides whether it must route the telegrams or not. If the line repeater has not yet received its own physical address, it can cause faults when commissioning other devices. address of a receiver, the line repeater can repeat the telegram. It is not repeated in the default setting in order to keep the telegram load as small as possible. This behaviour can be set separately for both line segments with the parameters epetitions if errors in assigning physical addresses. If the line repeater routes a telegram and does not receive an acknowledgement or if a bus device establishes a transmission error, the line repeater by default repeats the telegram twice at most. This behaviour can be set separately for both line segments with the parameters epetitions if errors in group telegrams.
