SENSe:DIGital:DATA
[:<BYTE|WORD|LWORD>]:BLOCK? <port>,<size>
This query returns block data. Block data has the form:
<#digits><length><block>, where:
•
<#digits> decides how many decimal digits are used to define
<length>;
•
<length> decides how many bytes are to be transferred in <block>;
•
<block> contains the actual data to be transferred. <block> may
contain from 1 to 2048 bytes.
The returned block will contain the number bytes specified in <size>. The
value of size will be the value of length in the returned block.
Set port to 090 to read blocks on the built-in 4-bit digital I/O port.
The first parameter sets the value returned. If you omit the parameter,
BYTE data is assumed.
Digital Output Commands
These commands set individual bits or complete ports. Some digital I/O
configuration commands may affect how these bits are implemented. The
port parameter is in the form snn, where s is the slot number and nn is
the first channel on the digital port. The port parameter is plug-in
module dependent. Valid port numbers for each plug-in module are
shown beginning on page 70.
SOURce:DIGital:DATA
:BIT <bit_port>,<0|1>
This command sets a bit in the specified bit_port. bit_port is in the form
of snn, where s is the slot number and nn is the bit number. The built-in
4-bit digital I/O port has bit numbers 091 to 094. The plug-in module bit
numbers are module dependent (see page 70).
