Input/Output SEND_COMMANDs
The I/O port is port 22 on the NX-series controllers and the MCP-108 Massio ControlPad.
The following SEND_COMMANDs program the I/O ports on the Integrated Controller.
I/O SEND_COMMANDs
Command
Description
GET DBT
Get Debounce Time
Syntax:
GET DBT <n>
Variable:
n = the channel number of the I/O input port
Example:
SEND_COMMAND 5001:22:0,'GET DBT 1'
Retrieves the Debounce time channel 1 on the I/O port.
Response:
DBT 1 50
Responds with the channel number and the Debounce time in milliseconds (ms).
SET DBT
Set Debounce Time
Syntax:
SET DBT <n><v>
Variables:
n = the channel number of the I/O input port
v = Value 1-50 which sets the debounce time in increments of 5ms
Example:
SEND_COMMAND 5001:22:0,'SET DBT 1 10'
Sets channel 1 on the I/O port to 50ms Debounce time.
GET INPUT
Get the active state for the selected channels. An active state can be high (logic high) or low (logic low or contact closure).
Channel changes, Pushes, and Releases generate reports based on their active state. The port responds with either 'HIGH'
or 'LOW'.
Syntax:
SEND_COMMAND <DEV>,"'GET INPUT <channel>'"
Variable:
channel = Input channel 1 - 8.
Example:
SEND_COMMAND IO,"'GET INPUT 1'"
Gets the I/O port's active state.
The system could respond with:
INPUT1 ACTIVE HIGH
SET INPUT
Set the input channel's active state. An active state can be high (logic high) or low (logic low or contact closure). Channel
changes, Pushes, and Releases generate reports based on their active state. Setting an input to ACTIVE HIGH will disable
the ability to use that channel as an output.
Syntax:
SEND_COMMAND <DEV>,"'SET INPUT <channel> <state>'"
Variable:
channel = Input channel 1 - 8.
state = Active state HIGH or LOW (default).
Example:
SEND_COMMAND IO,"'SET INPUT 1 HIGH'"
Sets the I/O channel to detect a high state change, and disables output on the channel.
