Checking the State of an I/O Line Using Direct Register Access

To check the current state of an I/O line via direct register access:

 For the CC1 line, read the value of the Line Status CC1 register. The value will indicate 1 (true)

or 0 (false).

 For the CC2 line, read the value of the Line Status CC2 register.

 For the CC3 line, read the value of the Line Status CC3 register.

 For the CC4 line, read the value of the Line Status CC4 register.

 For the CL Spare line, read the value of the Line Status CL Spare register.

For more information about direct register access, see Section 3.2 on page 16.

5.7.2 Checking the State of All Lines

Checking the State Using Basler pylon

You can determine the current state of all input and output lines by reading the value of the Line

Status All parameter. You can read the Line Status All parameter value from within your application

software by using the pylon API. The following code snippet illustrates using the API to read the

parameter value:

int64_t lineState = Camera.LineStatusAll.GetValue( );

The Line Status All parameter is a 32 bit value. As shown in Fig. 9, certain bits in the value are

associated with each I/O line, and each of these bits will indicate the state of the associated line. If

a bit is 0, it indicates that the state of the associated line is currently low. If a bit is 1, it indicates that

the state of the associated line is currently high.

You can also use the Basler pylon Viewer application to easily read the parameter.

Checking the State Using Direct Register Access

To check the current state of all I/O lines via direct register access, read the value of the Line Status

All register. The register holds a 32 bit value that indicates the state of each I/O line. The mapping

of the bits in the value to I/O lines is similar to the mapping described above for access via Basler

pylon.

For more information about direct register access, see Section 3.2 on page 16.
