*1 The first 3 digits of the hexadecimal 4 digits which represent the start I/O number.
*2 Local devices and the devices designated for individual programs cannot be used.
Processing details
• The contents of the data stored in the area starting from (S1) are as indicated below.
• Instruction execution possibility of an execution type for each program.
• To write data to a refresh device, the data reflection to the station number specified by the instruction is executed at the
timing for the auto refresh.
• QnUD(H)CPU, QnUDE(H)CPU: the serial number (first five digits) is "14072" or later
• QnUDVCPU: the serial number (first five digits) is "16043" or later.
• Built-in Ethernet port LCPU: Supported
• Q00UJCPU, Q00UCPU, Q01UCPU, Q02UCPU, L02SCPU, and L02SCPU-P cannot be used.
