Read Module Configuration

[cmdchars] = j

Description

The Read Module Configuration command reads the current direction (input or output) of all channels of the addressed FieldPoint module.

Syntax

j

Success Response

A[config]

[config]

Four ASCII-hex characters specify the directions of the channels of the module. A "1" in any bit means that the corresponding channel is configured as an output. A zero in any bit means that the corresponding channel is configured as an input. This command returns a zero for any bit that does not correspond to a channel. For example, if the command is sent to an eight-channel module, it returns configuration data for the lowest eight bits and zeros for the highest eight bits.

Error Responses

E_INVALID_CMD	Undefined command.
