Digital I/O and Relay Output

Counter/Frequency Command Set

#AAN

 

Name

Read Counter or Frequency Value command

Description

Instructs the addressed counter/frequency module at

 

address AA to read the counter or frequency value of

 

counter 0 or counter 1 and return the acquired data.

Syntax

#AAN(cr)

 

# is a delimiter character.

 

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

 

address that you will access to.

 

N represents the counter number.

 

N=0 represents counter 0

 

N=1 represents counter 1

 

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

Response

>data(cr) if the command is valid.

 

?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 an invalid

 

command.

 

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

 

address of the module.

 

(data) is the value that is retrieved by the module from

 

reading counter 0 or counter 1. The data format consists of

 

eight hexadecimal characters.

 

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

Example

command: #120(cr)

 

response: >000002FE(cr)

 

The command requests the counter/frequency module at

 

address 12 to read the counter 0 and return the data. The

 

counter/frequency module at address 12 responds with

 

value 000002FE (hexadecimal) of counter 0 which is also

 

equivalent to 766 (decimal).
