MP900-Series Machine Controller and MELSEC Register Maps
The following table shows the correspondences between MP900-Series Machine Controllers
and MELSEC devices. Each MELSEC device is allocated to an MP900-Series Machine
Controller M register (holding register, input register, input relays, or coils). The MW regis-
ters correspond to holding and input registers, and the MB registers correspond to input
relays and coils.
