Changes in 1 channel are always visible on the other channel as well. All further parameters can be set sepa-
rately for individual channels.
Setting Device-Combination Settings
•
Default setting
(_:5131:102) Address of device 1
=
101
•
Default setting
(_:5131:103) Address of device 2
=
102
•
Default setting
(_:5131:104) Address of device 3
=
103
•
Default setting
(_:5131:105) Address of device 4
=
104
•
Default setting
(_:5131:106) Address of device 5
=
105
•
Default setting
(_:5131:107) Address of device 6
=
106
The parameters
Address of device 1
to
Address of device 6
can be used to give an address to each
device. Set a unique and unambiguous address for each device.
•
Default setting
(_:5131:101) Local device is device
=
1
With the
Local device is device
parameter, you set the index (number) of your device in the topology.
A maximum of 6 devices can be present in 1 topology.
APPLICATION EXAMPLE
You have a topology with 2 devices.
For example, in DIGSI 5, select the parameter setting
Address of device 1
with the parameter value
101
for device 1 and the parameter setting
Address of device 2
with the parameter value
102
for device 2.
Then, use the
Local device is device
parameter to set the index of the local device.
The addresses must be configured identically for all devices involved in the constellation. A functional protec-
tion communication requires that you also assign the same index in all devices of a constellation for a device
with a unique address.
•
Default setting
(_:5131:122) Lowest appearing bit rate
=
64 kBit/s
The
Lowest appearing bit rate
parameter is used to set the lowest bit rate occurring in the device
group. Set the lowest value in each device with a three-end constellation with 2 fiber-optic connections (2
MBit/s) and a 64 kBit/s connection with the lowest value (64 kBit/s). This value determines the maximum
signals and measured values within a constellation.
Apart from the default value, you can also set the following bit rates:
•
128 kBit/s
•
512 kBit/s
•
2048 kBit/s
i
i
NOTE
If you use optical fibers for the connection between the devices, set the value to
2048 kBit/s
.
•
Default setting
(_:5131:125) Number of devices
=
6
With the
Number of devices
parameter, you set the number of devices actually connected in the device
combination in one topology. This parameter is set by default to the maximum number of devices permitted
for the appropriate constellation.
The
Number of devices
parameter depends on the configuration of the protection interface. When config-
uring the protection interface, select the maximum number of devices present in the final phase of the system
in the Select constellation text box. If the current expansion phase of the system contains fewer devices at
this time, set the number of devices actually in the device combination using the
Number of devices
parameter. In this procedure, all settings, for example, routing, you made for your constellation are retained.
