Solution:

PCLS-INT/4K doesn't support advanced instructions for ADAM-4018M, that means you only can use ADAM-4018M to acquire data just like 4018 under PCLS-INT/4K. Actually, no driver or software package provided by Advantech (such as PCLS-INT, PCLS-FIX, Genie/VisiDAQ/GeniDAQ, 32-bit dll driver) can allow you to get stored data from ADAM-4018M directly, only ADAM utility can do that. If you want to improve this situation, maybe you should try to develop the program by yourself, just like VBA under Genie. The data storage function of ADAM-4018M is not suitable for SCADA software, so you can see 4018M acts like 4018 under these SCADA softwares.
