Response Format
Parameters
Parameters will be written regardless of the operating mode of the CPU Unit.
There are some settings in the PLC Setup that cannot and will not be written if
the CPU Unit is in RUN mode, but the end code will be 0000 nevertheless. It is
the user's responsibility to program steps to prohibit this command from being
executed when the CPU Unit is in the RUN mode if such protection is neces-
sary. Execute CPU UNIT STATUS READ (command code 0601) to read the
CPU Unit's mode. (Refer to 5-3-17 CPU UNIT STATUS READ: 06 01.)
Data can only be written to the I/O registration table when the CPU Unit is in
PROGRAM mode.
All words in the specified parameter area must be written at the same time to
ensure complete data. A maximum of 498 words can be written with each
command. Nothing will be written if more than 498 words are specified. To
write larger parameter areas, use multiple commands and specify the begin-
ning word for each.
Except for the routing table area, each area must be read or written in its
entirety.
Writes all zeros to the specified number of consecutive parameter area words
to clear the previous data. The I/O table can be cleared only when the CPU
Unit is in PROGRAM mode.
Note Some PLC Setup parameters cannot be written in RUN or MONITOR mode.
