AioEnableAo

Function

The relay circuit of specified channel is made ON status.

Format

Ret = AioEnableAo ( Id , AoChannel )

Parameters

Id [ C, C++ : short ] [ Python： ctypes.c_short ]
Specifies the Device ID retrieved from AioInit function.

AoChannel [ C, C++ : short ] [ Python： ctypes.c_short ]
Specifies the channel its relay is to be made ON.

Return value

Ret [ C, C++ : long ] [ Python： ctypes.c_long ]

Return values	Content
0	Normality completion
7	Execute AioResetDevice function because the device has recovered from standby mode
10001	Invalid Id was specified Use the Id retrieved from AioInit to specify the Id in this function.
10002	AIO driver can't be called At first, perform AioInit function.
13360	The value of AoChannel is outside the designated range of the function Specify the channel setting in range: 0 <= AoChannel <= Max channel.
20001	This function can't be used by this device
20003	Can not use because another process is using the device When another process is using the device, all functions except for those that support multi-process can not be performed.

Initial value

The relay circuit of all channels is OFF for all devices.

Remarks

Starts the device action by using AioStartAo function, but the device actually output after AioEnableAo is executed.

When simple output functions are used, the relay circuit status become ON when AioSingleAo or AioMultiAo is executed regardless of the AioEnableAo function.

This function cannot be used on devices without the analog output function.
This function can be executed even if the device is in operation.
