CHAPTER 4: CONFIGURATION
3. If the Tie Line should be directed from the Sub to the Master, select Master/Slave CON Unit in the Choose Extender Type
selection box. If the Tie Line should be directed from the Sub to the Master, select Master/Slave CPU Unit in the Choose Extender
Type selection box.
4. Enter an appropriate extender name into the Name field.
5. Enter a port number into the Port field according to the required connection of the Tie Line.
6. Confirm your settings by pressing the Apply button.
7. If you have created a Master/Slave CON Unit, select Definition > CON Devices in the task area of the master matrix and press
the New button. A switchable CON Device will be created.
8. If you have created a Master/Slave CPU Unit, select Definition > CPU Devices in the task area of the Master Matrix and press
the New button. A switchable CPU Device will be created.
9. Enter an appropriate extender name into the Name field.
10. Assign the previously configured Extender Unit to the just created Device by moving the Extender Unit from the Extender
available field into the Extender assigned field and save your settings by pressing the Apply button.
11. Connect to the Sub Matrix and repeat steps 1 to 10.
12. Select System > System Data in the task area of the Sub Matrix and activate the Sub Matrix option.
The OSD of the Sub Matrix will immediately freeze and will be only accessible by using the keyboard command <Hotkey>, <s>, <o>.
13. Restart all I/O boards on which any Master/Slave CON or CPU Units have been configured or alternatively restart the matrix.
14. Connect the Tie Lines to the matrices. Ensure that each Master/Slave CON on one matrix is connected to Master/Slave CPU
on the other matrix in order to achieve switchability between two matrices.
The Matrix Cascading is now configured and can be used. Additional Tie Lines are configured accordingly. The use of cascading
is described in Section 5.1.4.
4.15 MATRIX GRID
In this menu, you can configure a Matrix Grid to connect two or more matrices. This kind of configuration may be necessary
if the number of ports in the entire system has to be increased or if certain important connections should be distributed to several
matrices because of redundancy.
The connections between two matrices have to be established by Grid Lines that are connected between particular I/O ports as
connecting links. The Grid Lines can be used bidirectionally and can respectively handle a full access connection of a CON Device
to a CPU Device.
The number of Grid Lines in the system specifies if a CON Device can be switched to a CPU Device in Non-Blocking Access
or in Blocking Access and has to be separately determined for each Grid environment.
In this case, Non-Blocking Access means that a Grid Line for a cross-matrix switching operation of a CON Device to a CPU Device
is available at any time.
Blocking Access means that for a certain switching operation no Grid Line may be available according to the switching status
within the Grid. As a result, no cross-matrix switching will be possible.
