psData Read data storage destination
Description
• This function reads data for the size specified for the read data size (plSize) from a device specified to the device type
(lDevType) and the start device number (lDevNo) of a module specified to the network number (lNetNo) and the station
number (lStNo).
• When the read size exceeds the device range, the readable device size (the maximum value that can be specified for the
read size (plSize) when '0 was specified for the start device number (lDevNo)) is returned to the read data size (plSize).
