GX Work 2 instruction question

[aoto10]

I'm looking through a program at work on GXworks 2 I see this instruction. [D<> K0 K7M2160] I'm confused as to how it works. I see it as a comparative function if the value of K7M2160 is anything other than 0 then the bit becomes true. But where is the value coming from? It's not like a normal data register. Is it looking for the value of word M2160 or is it looking for any word value from M2160 to M2166? Also what does the "D" mean in front of the "<>"?
Thanks in advance.

PLC CPU is Q03UDECPU. q-series.

I'm only guessing but D as a prefix in Mitsubishi talk usually means double register or 32 bit.

The way it was explained to me, it is looking for any value that is not zero from M2160 to M2166.

It's a 32bit compare, it's comparing bits M2160 to M2184 ( the K7 indicates 7 nybbles which = 28 bits - 7x4bits ) to k0 - zero.

Oops M2160 to M2188 (can't add)
