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).	RW	0xFFFF
80n0:15	User calibration offset	Reserved parameter	RW	0x0000
80n0:16	User calibration gain	Reserved parameter	RW	0xFFFF
