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.

This chapter describes examples when a QCPU, QnACPU, or ACPU is used as a

CPU module and GX Developer is used as a programming tool. For the case when a

LCPU is used as a CPU module or GX Works2 is used as a programming tool, refer to

the user's manual for the master module used.

In addition, for details on a master module and dedicated instructions described in

each program example, refer to the user's manual for the master module used and

Type AnSHCPU/AnACPU/AnUCPU/QCPU-A (A Mode) Programming Manual

(Dedicated Instructions) respectively.

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

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.
