Panasonic PLC RS485

Hi, does anyone familiar with the Panasonic PLC FP0R-C16MT with RS485 communication?

I got a sample program which is working, but it is different with what I read in manual.  (Control word part)

Can anyone help explain this to me?

Picture below shows what is inside manual

Example from manual

This is sample program

In this sample program, the control word part is direct insert value which is 1301 in hex. But according to manual, this area should be 2 word instead of one. 

But I had tested this sample program which is working fine.
