4080, 4080D

Digital I/O and Relay Output

Counter/Frequency Command Set

$AA0L(data)

 

Name

Set Minimum Input Signal Width at Low Level command

Description

Set the minimum input signal width at low level for a

 

specified counter/frequency module to filter noise.

Syntax

$AA0L(data)(cr)

 

$ is a delimiter character.

 

AA (range 00-FF) represents the 2-character hexadecimal

 

address that you will access to.

 

0L is the Set Minimum Input Signal Width at Low Level

 

command.

 

(data) is the minimum width at low level. The unit is in

 

μsec (microseconds) and its resolution is 1 μsec. The

 

format is a five digit integer that can range from 2 μsec to

 

65535 μsec. Out of range values will cause errors.

 

(cr) is the terminating character, carriage return (0Dh).

Response

!AA(cr) if the command is valid. The addressed module

 

stores the value and will identify the input signal “low”

 

only if the input signal continues to be “low” longer than

 

the specified time.

 

?AA(cr) if an invalid operation was entered.

 

There is no response if the module detects a syntax or

 

communication error, or even if the specified address does

 

not exist.

 

! is a delimiter character which indicates a valid command.

 

? is a delimiter character which indicates an invalid

 

command.

 

AA (range 00-FF) represents the 2-character hexadecimal

 

address of the module.

 

(cr) is the terminating character, carriage return (0Dh).

Example

command: $050L00084(cr)

 

response: !05(cr)

 

The command requests the counter/frequency module at

 

address 05 to set the minimum input width at low level to

 

84 μsec. The module stores the value and will identify an

 

input signal to be "low” only if the signal continues to be

 

“low” longer than 84 μsec. This function can be used as

 

digital filter.
