5 PROGRAMMING 

The programming procedure, basic read/write programs, and program examples for 
the AJ65SBT-64AD are described. 
When utilizing the program example introduced in this chapter for an actual system, 
fully verify that there are no problems in controllability in the target system. 
Refer to the user's manual of the master module used for the master module, to 
Section 3.6 for the remote registers, and to the AnSHCPU/AnACPU/AnUCPU 
Programming Manual (Dedicated Instructions) for details of the dedicated instructions. 

 

5.1 Programming Procedure 

Create a program which executes the AJ65SBT-64AD analog/digital conversion by 
following the procedure below: 

 

START

Perform moving average processing?

END

No

Yes

A/D conversion enable/prohibit specification

Input range setting

Moving average processing count setting

Specify the channel for which moving average 
processing will be performed.

Read digital output value 

Initial settings*

 

 
*  When using the QCPU (Q mode), you can use the remote device station initialization 

procedure registration function to make settings. When using the ACPU, QCPU (A 
mode) or QnACPU, use the sequence program to make settings.
