The relationship between the dynamic switch setting, link function selection (function code H30), 
and link operation selection (digital input LE) is shown below.

Note: 
5  The DIO option (OPC-VG1-DIO) is necessary to reference data Y11-Y18 for the FRENIC-VG 
DO1 (standard + DIOA: 13 bits). This command is effective without regard to the status of the 
function code H30 and link operation selection LE. 
9  The DIO option (OPC-VG1-DIO) is necessary to reference data for the FRENIC-VG DO2 
(DIOB option: 10 bits). This command is effective without regard to the status of the function 
code H30 and link operation selection LE. 
  AIO option (OPC-VG1-AIO) is necessary to reference data for the FRENIC-VG AO (AIO 
option, AO4) / (AIO option, AO5). To output this command to the AO terminal, you need to 
assign the corresponding AO terminal functions to the universal AO (U-A0) using the function 
codes E69 to E73. This command is effective without regard to the status of the function code 
H30 and link operation selection LE.

  Use the "polling function code (1) to (8)" (8 bits) to specify the link number corresponding to the 
function code number requested for polling.
