Sensoray526 Dual DA block
Simulink® Real-Time™ Library for Sensoray
To perform simultaneous conversion with two boards, control both boards simultaneously with the Sensoray526 Dual DA block. The block writes the output registers to both boards before writing the conversion start bits to both boards.
Output from the second board changes state approximately 1–2 microseconds after the first board. This change is independent of the number of channels in use.
Block Input Data Type
Enter a vector of numbers between 1 and 4. Do not repeat channel numbers. For example, to use the first, second and fourth channels, enter
[1, 2, 4]
Number the channels beginning with 1 even if this board manufacturer numbers them beginning with 0.
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
replicated over the channel vector. If you specify a value of
the corresponding channel is reset to the value specified in the initial
value vector. If you specify a value of
channel remains at the last value attained while the model was running.
The initial value vector contains the initial voltage values
for the output channels, used by the block at initialization. If Reset
vector has a value of
1, the board sets
the corresponding channel to the value of the Initial value
vector when execution stops. Enter a double precision voltage
value in the range -10 to +10. This must be scalar or a vector that
is the same length as the channel vector. If you specify a scalar
value, that value is replicated as initial value over the channel
vector. The channels are set to the initial values between the time
the model is downloaded and the time it is started.
Enter the base sample time or a multiple of the base sample
-1 means sample time is inherited).
Enter the base address of the board. This entry must correspond to the base address DIP switch settings on the board. For example, if the base address is 2C0 (hexadecimal), enter
Note that the Sensoray 526 board ships from the manufacturer with a base address of 0x2C0. If you want to change the base address, see the board manufacturer documentation for allowed values. For dual boards, change the base address of at least one of the boards. The boards cannot have the same base address.
