'MultiInstance' can be used to run two instances of SAMLight on the same PC at the same time. Both instances can run independently at the same time.

Requirements:

•1 PC

•2 USC cards (each card require a SAMLight license)

For a system with two card, initially two settings files are required. The file sc_light_settings.sam is copied twice and renamed to MultiInstance_0.sam and MultiInstance_1.sam. Then, two shortcuts of SAMLight must be generated, SAMLight MultiInstance 0 and SAMLight MultiInstance 1.

To differentiate between the two shortcuts, each shortcut needs its own settings and its assigned card. This is done using command line parameters. These can be assigned under properties of the respective shortcut.

For SAMLight MultiInstance 0 you will need the following command line parameter:
..\sam_light.exe /MultiInstance /ActiveCard=0 /Settingsfile=MultiInstance_0.sam

For SAMLight MultiInstance 1 you will need the following command line parameter:
..\sam_light.exe /MultiInstance /ActiveCard=1 /Settingsfile=MultiInstance_1.sam

You will find information on the Command line parameters in the chapter How to → Command Line Parameters.

Settings for MultiInstance in visible USC server:

•Map card for SAMLight MultiInstance 0 to position 0

•Map card for SAMLight MultiInstance 1 to position 1

Each SAMLight instance will show its corresponding Dongle number of the USC-card.

 

The instance of SAMLight can also be remotely controlled using other software via CCI. In the case of 'MultiInstance', CCI function calls do not work, but CCI TCP with different ports does work. For further information on CCI TCP, please take a look at the CCI manual.

If 'MultiInstance' is used, only motion types 8 and 14 can be used. Command line parameters are also used to assign a motion settings file to the instance. The command line parameter to use is /StepperMotionFile=<*.txt>.
