Understanding and Converting Mitsubishi Instructions

[Olyn 0]

Hi! I'm working on migrating a project from Mitsubishi PLC to Siemens and having a hard time to convert some instructions and logic. Anyone here can explain what are these instructions? (attached photo) Can someone help me convert them into simple logic so I can write them to TIA? Thanks!

Why Migrating to siemens when converting to the latest Mitsubishi PLC is so easy ?

I know but migrating to Siemens is what the plant owner wants, not mine. If I would be the one to decide then I'd stay with Mitsubishi.

The instructions are ofc in the manual. 

But DateRD is just reading the Date form the PLC into D0 D1 D2 etc.

 BLKRST is a block reset resetting M1100 and the next 500

M1000Z0 --- Z0 is an index on the device . (lets say Z0= 20 then M1000Z0 is actually M10020)

What is unclear about the other part ?

oh thank you, now it makes sense. i'd like to know if D0 and Z0 is just the same? I mean, are they just data registry? is the slash (/) on the rung is a NOT/Invert?

D0 and Z0 are both word devices but only Z can be used for indexing another device.

As for the slash you are correct
