AIO_OutW Statement
Output 16 bits analog value from optional analog I/O output channel.
Syntax
AIO_OutW Channel Number, Output data [, Forced]
Parameters
- Channel Number
- Specify the channel number of the analog I/O.
- Output data
- Specify the output data (integer from 0 to 65535) using an expression or numeric value.
- Forced
- Optional. Usually omitted.
Description
Output to analog I/O channel specified by channel number. For the output data, specify integer expression from 0 to 65535 in formula or value.
Output voltage (current) is as follows according to output range configuration which is set by the switch on the board.
| Output Data | Output Range Configuration | ||||||
|---|---|---|---|---|---|---|---|
| Hexadecimal | Decimal | ±10(V) | ±5(V) | 0-5(V) | 0-10(V) | 4-20(mA) | 0-20(mA) |
| 0xFFFF | 65535 | 9.99970 | 4.99985 | 5.00000 | 10.00000 | 20.00000 | 20.00000 |
| 0x8001 | 32769 | 0.00031 | 0.00015 | 2.50008 | 5.00015 | 12.00024 | 10.00031 |
| 0x8000 | 32768 | 0.00000 | 0.00000 | 2.50000 | 5.00000 | 12.00000 | 10.00000 |
| 0x0000 | 0 | -10.00000 | -5.00000 | 0.00000 | 0.00000 | 4.00000 | 0.00000 |
Note
Forced Flag
Specify the flag if outputting the analog I/O when operating emergency stop or opening the Safety Door by NoPause task, NoEmgAbort task (special task specified NoPause or NoEmgAbort to start when executing Xqt), and background task.
Need to be careful about the system design since analog I/O output changes when operating emergency stop or opening the Safety Door.
