■ Description
• This function reads devices specified to the randomly selected device (plDev) from a module specified to the network
number (lNetNo), the start I/O number (lIoNo), the station number (lStNo), and the CPU number (sCPU).
• The read data is stored in the read data storage destination (psBuf) in word units in order of the specification to the
randomly selected device (plDev). A bit device and a word device are stored per 1 point, and a double-word device is
stored in word units.
• Specify so that the total number of read points specified for each block is 10240 points or less. Otherwise, a size error (-5)
will occur.
• When '0' is specified to the label code (ullLbCode), the device is read without checking the label code.
