Recipe Function
■ Read Trigger
Specifies the device that triggers batch reading values of devices and saving them to the external memory as a recipe
file.
Click to display the Device Address Settings dialog box. For the device address configuration procedure, refer to
Chapter 2 “5.1 Device Address Settings” on page 2-62.
This option can only be configured when Read/Write or Read-only is selected under Trigger Setting.
■ Write Trigger
Specifies the device that triggers batch writing recipe values to devices by block.
Click to display the Device Address Settings dialog box. For the device address configuration procedure, refer to
Chapter 2 “5.1 Device Address Settings” on page 2-62.
This option can only be configured when Read/Write or Write-only is selected under Trigger Setting.
■ Monitoring Period
Shows the period to monitor the write device and the read device. This period is for detecting alarms so it is the same
as the period to monitor device states. This option is configured on the General tab in the Alarm Log Settings dialog
box.
Each bit of the word device configured by the read trigger corresponds to a channel.
When a bit changes from 0 to 1, a read to the device is executed.
Example: When the block 1 read trigger is specified as LDR0000
LDR0000-0 corresponds to channel 1-0, LDR0000-1 to channel 1-1, through to LDR0000-15 which
corresponds to channel 1-15.

• When recipe values are batch written to devices with Access to set to External Memory and Trigger
Setting set to Read/Write or Write-only, if no recipe file exists in the “RECIPE” folder in the External
Memory Folder on the external memory, 0 is written to all the devices.
• If a value of device reads and recipe value writes occur simultaneously, first the values of devices are
read, then the recipe values are written.
