CHAPTER 10
This chapter describes the procedure for programming and the basic program of the D/A converter module.
10.1

Procedure for Programming

Create a program executed by D/A converter module according to the following procedure.
Use the configuration
Switch setting, parameter setting,
and auto refresh setting
Error reset program
*1 A program which is created according to the used function.
*2 A program which is added according to the control target. (Create it as needed.)
*3 When the wave output function is used, setting "D/A conversion enable/disable setting" to "0: Enable" in the parameter
setting of the configuration function will cause an error at the start-up of the D/A converter module. The error code (33)
is stored in Latest error code (Un\G19), Error flag (XF) turns on, and the ERR.LED turns on. This error occurs because
the wave pattern data points setting is set to 0 (default value) for the channel where D/A conversion enable is set.
To prevent the error, set D/A conversion enable by the procedure described in the following section.
