This section explains the format of the IOWR instruction. For details, refer to "Instructions
Reference Manual (W474)" for the CS/CJ-series PLC.
Specify the parameter type of the data to be written
The amount of common, axis or memory operation parameters that are writable per instruction
corresponds to 1 Unit Address. You cannot write multiple parameters with 1 instruction.
The memory operation data and memory operation condition data that are writable per
instruction is within for 1 sequence or within the range of 1 condition. You cannot write the data
of multiple sequences or multiple conditions with 1 instruction.
Prepare the transfer data as follows in the word which you specified in S.
However, the transfer data for the feedback counter present value (parameter type: 1101 to
