Manual for using the Remote Connection Switcher driver
Requirements for usability
- TS Firmware: from V10SP14 2017111714 or from V11SP00 2017111714
- ToolScope Connector: from 20171204
- PLC program which outputs special signals (see text)
- 2 ToolScopes und 1 ToolScope Connector inside a network
Function of the driver
This driver is for the specific situation where a machine has more than one NCUs and the ToolScope Connector should be able to switch between ToolScopes.
For this, a signal is set in the driver, which the driver should monitor. Then there is a list of ToolScope IP addresses to enter, which the ToolScope Connector should later connect to. The driver ensures that the monitoring sees only the value "0" in the selected signal to avoid unwanted triggers.
The number in the monitored signal (special signal) represents the ToolScope IP list entry to which the ToolScope Connector should connect. If a "0" is present in the monitored signal, the ToolScope Connector will be sent to the next IP in the list. This signal must be generated on the NCUs of the machine. For this a PLC program can be written. If every NCU has its own connection to its ToolScope, the corresponding NCU signal must match the ToolScope. Example: The NCU1 writes a "1" to the monitored signal when ToolScope1 is active, otherwise "0". The NCU2 writes a "2" to the monitored signal when ToolScope2 is active, otherwise "0".

Activate the driver
Since this is a very special driver, it must first be activated via a special menu. To do this, open the menu item "Other" under settings. On the right side, set the entry
“ShowDriverRemote~Connection~switcher” to “1”. To search for the entry, it is sufficient to enter only "Remote", so that the entry appears in the list.

Configuration of the driver
The driver needs following information’s to work:
- The number of ToolScopes between the ToolScope Connector should switch.
- The monitored signal
- Will be explained in the next chapter, decides the mode of the driver
- Specifies the default ToolScope IP to which the ToolScope Connector will be send, if the ToolScope does not find itself in the list (point 5).
- The list of ToolScope IP addresses
For 2: note that the driver, which contains the monitored signal, has to be activated beforehand to appear in the selection box.
For 5 you just have to remember that the PLC program and the list have to be coordinated with each other. If the NCU supplies the value "1" for its ToolScope, the IP of this ToolScope should also be listed under "ToolScope IP1" in the list. Overall, it's about the driver trying to find its own ToolScope IP in the list, then sending the ToolScope Connector to the entry afterwards. For example, in case of wrong arrangements, only 3 out of 10 ToolScope IPs could be usable when point 3 sends to point 1.
For each ToolScope mentioned in 5, this process must be repeated in the corresponding ToolScope.

Use a button to change the connection.
If the change of the connection should not happen by a signal but by pressing a button, this can be activated. In Figure 3, point 3 is responsible for this. If the lower checkbox is clicked, a switch is used, otherwise a signal. Only one of the two checkboxes can be active.
Figure 4 shows the switch at the bottom left.
