When configuring the input and output data size, please ensure the following steps are taken;
•The minimum value of both the input and output data size is 2 bytes.
If the EX600 data size is 0 or 1byte, this must be set to 2 bytes.
•If the input or output size is an odd number, add 1 byte, to make it an even number of bytes.
The I/O map is shown with the following unit configuration as an example.
