*2You cannot set the duplicate address for X and Y, T and C.

    (Setting such address as X000/Y000, EX000/EY000, T000/C000, ET000/EC000 is wrong.)

*3When you write the bit address, the Display reads the word address corresponding to that of the External Device first. Then, it changes the target bit address among the word data once read and returns the word data to the External Device. Note that the correct data may not be written if you change the word address value in the ladder program while the Display reads and returns the data of the External Device.

*4The PC2J does not support the File Register.

*5When you write "Watch Time Register", the Display reads all addresses of "Watch Time Register" in the External Device. Then the Display writes all addresses of "Watch Time Register" after the Display changes the data of your requested address. Note that the correct data may not be written if you change the word address using the ladder program while the Display reads data from the External Device and returns it.

*6Contents of "Watch Time Register" are shown below.
