$AA4

 

 

Name

Read Synchronized Data command

 

Description

Returns the input value that was stored in the addressed

 

module’s register, after a Synchronized Sampling command

 

#** was issued.

 

Syntax

$AA4(cr)

 

 

$ is a delimiter character.

 

 

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

 

address of the analog input module from which data is to be

 

sent.

 

 

4 is the Read Synchronized Data command.

 

 

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

Response

!AA(status)(data)(cr) if the command was valid.

 

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

 

There is no response if the module detects a syntax error or communication error or if the specified address does not exist.

! delimiter character indicates a valid command was received.

AA (range 00-FF) represents the 2-character hexadecimal address of the analog input module that is responding.

(status) will tell you if the data (data) from the last Synchronized Sampling command (#**) has already been sent. If status = 1, then the data has been sent for the first time since a Synchronized Sampling command was issued. If status = 0, then the data has been sent at least once before.

(data) a value stored in a special register of the interrogated module in the configured data format. It has been sampled by the module after a Synchronized Sampling command. (For possible data formats, see Appendix B, Data Formats and I/O Ranges)

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