@AAEAT

 

Name

Enable Alarm command

Description

The counter module is instructed to enable its alarm for

 

counter 0 in either Latching or Momentary mode.

Syntax

@AAEAT(cr)

 

@ is a delimiter character.

 

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

 

address of the module.

 

EA is the Enable Alarm command.

 

T indicates the alarm type and can have the value M =

 

Momentary alarm state, or L = Latching alarm state.

 

(cr) represents terminating character, carriage return (0Dh).

Response

!AA(cr) if the command was valid

 

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.

 

AA represents the 2-character hexadecimal address of the

 

module.

 

(cr) represents terminating character, carriage return (0Dh)

Example

command: @03EAL(cr)

 

response: !03(cr)

 

The counter module at address 03h is instructed to enable

 

its alarm for counter 0 in Latching mode.

 

The module confirms that the command has been received.

NOTICE: A counter module requires a maximum of two seconds after it has received an Enable Alarm command to let the settings take effect. During this time, the module can not be addressed to perform any other actions.
