2. DETAILS OF MIGRATION FROM Q17nCPUN(-T) TO RnMTCPU
2.3.2 Special relays
[Point]
When Q17nCPUN(-T) projects are converted into RnMTCPU projects by “file conversion”, M9000 to
M9255 are automatically assigned as shown above in “Device assignment for M9000 to M9255” in
the table, however, M2320 to M3139 cannot be automatically converted.
Device No.
