Diamond Ruby-MM-1612 Digital Output - Ruby-MM-1612 Digital Output block

Library

xPC Target Library for Diamond

Note

Ruby-MM-1612 series boards have three I/O ports, each containing eight digital I/O lines. These ports can be configured independently for either input or output. Use a separate driver block for each port. By selecting the digital output driver block for a given port, you configure that port for output.

Block Parameters

Channel vector

Enter numbers between 1 and 8 to select the digital output lines used with this port. This driver allows the selection of individual digital output lines in any order. The number of elements defines the number of digital lines used.

For example, to use all the digital outputs for the current port, enter

[1,2,3,4,5,6,7,8]

Number the lines beginning with 1 even if the board manufacturer starts numbering the lines with 0.

Port

From the list choose A, B, or C.

Reset vector

The reset vector controls the behavior of the channel at model termination. Enter a scalar or a vector that is the same length as the channel vector. If you specify a scalar value, that setting is used for all channels. If you specify a value of 1, the corresponding channel is reset to the value specified in the initial value vector. If you specify a value of 0, the channel remains at the last value attained while the model was running.

Initial value vector

The initial value vector contains the initial voltage values for the output channels. Enter a scalar or a vector that is the same length as the channel vector. If you specify a scalar value, that value is the initial value for all channels. The channels are set to the initial values between the time the model is downloaded and the time it is started. If you provide a value that is out of the channel's range, the value is reset to the lower or upper range value.

Sample time

Enter a base sample time or a multiple of the base sample time.

Base address

Enter the base address of the board. This entry must correspond to the base address board setting. For example, if the base address is 300 (hexadecimal), enter

0x300
