Later models of S7 devices (1200 and 1500) begin using "Instructions" in place of SZL requests. Is there any way to perform these instruction sets via the Snap-7 library? Specifically, I'm interested in the possibility of performing a RDREC Instruction (SFB 52) using python-snap7. If this is not possible, I suppose you would need read the values into global data blocks on the PLC and then pull from there.

Hello,
