• <Command>: Command string which should be queued.
• <PIN>: Input pin number (valid from 0-31) where the first Pin is 0.
• <UP_DOWN>: 0 means the command should be executed on a trailing edge, 1
means the command should be executed on a raising edge.
• <COUNT>: The command will be executed <Count> times. The command will
executed once per event and NOT <Count> times per event. A value lower or equal
0 means that the command will never be removed from the queue.
Remarks: After the GPI event occurs, the execution time of the command
will be calculated. The execution time is calculated in the following way:
Ring_Buffer_Size*2+7+Delayed_Command_Bias. The <Delayed_Command_Bias> can
be set in the configuration file. Therefore Ring_Buffer_Size*2+7 is the minimum delay
for GPI triggered commands.
Command - Clear
VIZ_COMMUNICATION*GPI_PIN_COMMAND CLEAR <PIN> <UP_DOWN>
Clears all commands from the queue.
• <PIN>: Input Pin number (valid from 0-31) where the first Pin is 0.
• <UP_DOWN>: 0 means the command should be executed on a trailing edge, 1
means the command should be executed on a raising edge.
Information - Get
VIZ_COMMUNICATION*GPI_INFO GET
Sends information on the installed GPI device.
If a valid device is present the command will return the number of available GPI Banks.
Therefore a value of 1 means that 1 bank (8 inputs) is available.
If the command returns 0 no valid GPI device is present.
Pin Command - Test
VIZ_COMMUNICATION*GPI_PIN_COMMAND TEST <PIN> <UP_DOWN>
Sends all queued commands for the pin and signal to the Viz Engine. The counter for
the commands is not decremented.
• <PIN>: Input Pin number (valid from 0-31) where the first Pin is 0.
• <UP_DOWN>: 0 means the command should be executed on a trailing edge, 1
means the command should be executed on a raising edge.
Enable - Set
GLOBAL*GPI_ENABLE SET <1 or 0>
Enables or disables GPI commands for the Viz Engine. All functionality is available
except of sending the commands on a GPI signal. If disabled the command will be
displayed in the console and a warning is displayed, that GPI is disabled. The TEST
command is working as usual, even if GPI is disabled.
• 1 enables GPI execution
