ReceiveData
Receives data.
Format
ReceiveData <ioIdent>, <inputData()>, <inputMaxSize>, <inputSize>[, <parameter()>,
<parameterSize>]
Parameter
Return value
None.
Description
Receive data up to the size specified in the <inputMaxSize> parameter by using the communication module
specified in the <ioIdent> parameter.
In the <inputData()> parameter, specify the 1D integer array variable that will hold the data to be received,
without adding element numbers but adding () to the variables. In the <inputSize> parameter, specify the
integer variable that will hold the size of the received data.
Values that can be set in the <parameter()> parameter and <parameterSize> parameter depend on the
communication module specified in the <ioIdent> parameter. The <parameter()> parameter and
<parameterSize> parameter can be omitted.
With this macro function, data that has arrived at the sensor controller from an external device is received
when the macro function is executed. If no data has arrived, 0 is stored in the <inputSize> parameter. If the
desired data is not received the first time the macro function is executed, execute repeatedly until all data has
been received.
If an incorrect data type is specified for a parameter, a "Type mismatch" error will occur.
If a non-existent number, numerical value, or combination of data types or values is specified for a parameter,
an "Illegal function call" error will occur.
If Handshake is on and data reception fails due to a communication timeout or other reason, an "Illegal
function call" error will occur.
If the format is written incorrectly, such as writing the macro function name incorrectly, omitting a comma, or
omitting a half-width space, a "Syntax error" error will occur.
Usage Cautions
• Execute this macro function when the target communication module is stopped. (Reference: XExclusive
Control in a Process (p.234))
