Hi,

My base Twido has got 24 inputs, so I need two word registers to transfer the inputs to read it in SCADA, but am not able to assign the operate block as '%MW100:=%I0.16:23'. Is there any syntax error in this addressing? Twido only takes %i0.0 as the starting address in operate block, even I can't address as '%MW100:=%I0.1:17'.

Can anyone help me in this regard?

Thanks in advance.

My proposal is the following (tested)

LD 1
[%MW100:=%I0.0:16]
[%MW101:=%I0.16:8]

Best regards.
