Activate Outputs

[cmdchars] = K

Recommended Extended Commands

National Instruments recommends that you use the Write Discrete (!L) extended command or the Write Discrete with Status (!M) extended command instead of the Activate Outputs command.

Description

The Activate Outputs command drives targeted output channels ON on the addressed FieldPoint module.

Syntax

K[positions]

[positions]

Zero to four ASCII-hex characters specify the channels. A "1" in any bit turns the corresponding output ON. A zero in any bit means that the corresponding channel is unaffected. If [positions] contains one to three characters, the channels corresponding to missing bits are unaffected. If [positions] is empty, the command supplies "FFFF" for the value. This command does not affect input channels.

Success Response

A

Error Responses

E_INVALID_CMD	Undefined command.
E_INV_LIMS_GOT	Specified limits invalid for the command.
