COE Parameter Description
COE parameters 0x8000~0x8030 are used for parameter settings of the analog output module. The parameters marked with yellow “ ” are reserved and cannot be configured. Note: when n takes values from 0 to 3, it corresponds to channels 1 to 4 respectively.
| 0x80n0 AO parameter setting | ||||
| Index | Name | Meaning | Symbol | Default Value |
| 80n0:01 | Enable user scale | Enable user scaling | RW | 0x00 |
| 80n0:02 | Presentation | Reserved parameter | RW | 0x00 |
| 80n0:05 | Watchdog |
0: The default watchdog value in index 0x80n0:13 takes effect. 1: Watchdog value (watchdog ramp) The ramp defined in index 80n0:14 is activated when ramping to the watchdog value in index 80n0:13. 2: Last output value If the watchdog timeout occurs, output the data from the last process. |
RW | 0x00 |
| 80n0:07 | Enable user calibration | Reserved parameter | RW | 0x00 |
| 80n0:08 | Enable vendor calibration | Reserved parameter | RW | 0x01 |
| 80n0:11 | Offset | Offset | RW | 0x0000 |
| 80n0:12 | Gain |
User scaling gain. The gain is expressed in fixed-point format with a factor of 216.Value 1 corresponds to 65535 (0x00010000). |
RW | 0x00010000 |
| 80n0:13 | Default output | Output value in watchdog condition (when activated via Watchdog, index 80n0:05) | RW | 0x0000 |
| 80n0:14 | Default output ramp |
This value defines the ramp rate for ramping down to the default value. The value is specified in digits per millisecond.For example, if the input is 100 and the default value is 0, in the event of a fault the output value changes from the maximum value (32767) to the default value in 327 milliseconds (32767/100). |
