8.12 Trigger Output Function
8.12 Trigger Output Function
Using this function, the D/A converter module performs the D/A conversion at the timing of a trigger output request.
● This function can be used only when the drive mode is set to the trigger output mode.
● The D/A converter module converts analog values into digital values in all the channels where the D/A conversion is
enabled, every time Trigger output request (RY19) is turned on.
(1) Combination with the external signal assignment function
Using this function with the external signal assignment function enables the D/A conversion by the trigger output
request at when the remote input signal of the extension input module is turned on.
For the external signal assignment function, refer to the following.
• External signal assignment function ( Page 118, Section 8.15 (3))
An extension input module is required when the trigger output function is used with the external signal assignment function.
(2) Restrictions
The following table lists the restrictions on the trigger output function.
(3) Operation of the trigger output function
After the D/A conversion-enabled channel is set and Initial data setting request flag (RY9) is turned on and off,
the D/A converter module waits for trigger input.
Once Trigger output request (RY19) is turned on, the D/A converter module performs the D/A conversion for all
the channels where the D/A conversion is enabled.
