Function and operation explanation
1. 16-bit operation(FMOV, FMOVP)
The data or contents of a device specified by are transferred to "n" devices starting from a device
specified by .
• The contents will be same among all of "n" devices.
• If the number of points specified by "n" exceeds the device number range, data is transferred within the
possible range.
• While the command input is OFF, the transfer destination specified by does not change.
• While the command input is ON, the data of the transfer source specified by does not change.
• When a constant (K) is specified as the transfer source specified by , it is automatically converted into
binary.
2. 32-bit operation(DFMOV, DFMOVP)
The contents of the transfer source specified by are transferred to "n" 32-bit devices starting from the
device specified by .
• The contents will be the same among all of "n" 32-bit devices.
• If the number of points specified by "n" exceeds the device number range, data is transferred within the
possible range.
• While the command input is OFF, the transfer destination specified by does not change.
• While the command input is ON, the data of the transfer source specified by does not change.
• When a constant (K) is specified as the transfer source specified by , it is automatically converted into
