Programmer.
• An error will occur and the left bus bar will be
displayed in red if a hexadecimal value
including A to F is input without # from the
CX-Programmer.
• The input will be treated as an address in the
CIO Area and the contents of that address
will be specified if a decimal value without #
is input from the CX-Programmer.
