2. DETAILS OF MIGRATION FROM Q17nCPUN(-T) TO RnMTCPU
(11) Operation cycle
The operation cycle settings of Q17nCPUN(-T) can be imported to RnMTCPU when the
projects of Q17nCPUN(-T) are diverted to RnMTCPU in MELSOFT MT Works2.
(Refer to section 2.4.3(2) for details of project diversion.)
However, if the operation cycle is set as default (automatic), the operation cycle will be
changed. Set a fixed operation cycle where necessary by following the table below because
the change in the operation cycle may change program execution timing.

(Note-1): Operation cycle of 14.2ms is not settable for RnMTCPU.
If the operation cycle of 14.2ms is set in the Q17nCPUN(-T) project, the value is changed to
the “default value (automatic)” at project diversion. Review the setting as needed.
