Miscellaneous reference information for Zebra 4Sight

This section includes additional command reference information for Zebra 4Sight. The information found in this section might be a reiteration of content previously documented.

The following modules are mentioned in this section:

Msys​

This section presents information about Zebra 4Sight and the system module.

MsysControl/Inquire​

The following lists additional 4Sight support when using MsysControl/MsysInquire.

  • Support for inquire of an output: M_USER_BIT_STATE + M_USER_BIT[0...15]. Possible inquire values include:
    • M_OFF.
    • M_ON.
  • Support for inquire of an output: M_USER_BIT_STATE_ALL. Possible inquire values include:
    • M_OFF.
    • M_ON.
  • Support for inquire of an output:M_IO_STATUS + M_AUX_IO[0...15]. Support for inquire of an input: M_IO_STATUS + M_AUX_IO[16...31].
  • Support forM_IO_INTERRUPT_ACTIVATION + M_AUX_IO[16...31]. Possible control/inquire values include:
    • M_DEFAULT or M_EDGE_RISING.
    • M_EDGE_FALLING.
  • Support forM_IO_INTERRUPT_STATE + M_AUX_IO[16...31]. Possible control/inquire values include:
    • M_DEFAULT or M_DISABLE.
    • M_ENABLE.
  • Support forM_IO_MODE + M_AUX_IO[n]. Possible control/inquire values include:
    • M_OUTPUT for n = 0...15.
    • M_INPUT for n = 15...31.
  • Support for reading the current encoder position with MsysInquire. MsysInquire(Sys, M_ROTARY_ENCODER_POSITION+M_ROTARY_ENCODERn, &Position). Select n as 1 or 2 to choose the target encoder. Position is an AIL_INT.
  • Support for reading the current encoder position based on a signal event with MsysGetHookInfo. Possible events include:
    • The following associates a latch with a specific rotary encoder: MsysControl(Sys, M_SYS_DATA_LATCH_TYPE+M_LATCHm, M_ROTARY_ENCODERn). Select m as 1 or 2 to choose the target latch storage. Select n as 1 or 2 to choose the target encoder.
    • The following determines which signal will latch. In this case, the rotary encoder position: MsysControl(Sys, M_SYS_DATA_LATCH_TRIGGER_SOURCE+M_LATCHm, LatchTriggerSource). Select m as 1 or 2 to choose the target latch storage. LatchTriggerSource is an AIL_INT initialized with M_AUX_IOi, where i is from 8 to 15 or M_TIMERj, where j is from 1 to 16, on Zebra Indio.
    • The following determines which signal edge will latch the encoder position: MsysControl(Sys, M_SYS_DATA_LATCH_TRIGGER_ACTIVATION+M_LATCHm, LatchTriggerActivation). Select m as 1 or 2 to choose the target latch storage. LatchTriggerActivation is an AIL_INT initialized with M_EDGE_RISING, M_EDGE_FALLING, or M_ANY_EDGE.
    • The following activates (or deactivates) the given latch mechanism: MsysControl(AilSystem, M_SYS_DATA_LATCH_STATE+M_LATCHm, LatchState). Select m as 1 or 2 to choose the target latch storage. LatchState is an AIL_INT initialized with M_ENABLE or M_DISABLE.
    • The following allows you to retrieve the latched value in the context of a hook-handler function registered with MsysHookFunction: MsysGetHookInfo(EventId, M_SYS_DATA_LATCH_VALUE+M_LATCHm, LatchValue). Select m as 1 or 2 to choose the target latch storage. LatchValue is an AIL_UINT64 that returns the rotary encoder position that is latched. Note that if M_SYS_DATA_LATCH_TRIGGER_SOURCE was specified as M_AUX_IOi, the MsysGetHookInfo call is done in the scope of a hook function to M_IO_CHANGE. If M_SYS_DATA_LATCH_TRIGGER_SOURCE was specified as M_TIMERj, the MsysGetHookInfo call is done in the scope of a hook function to M_TIMER_START or M_TIMER_END.
