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

dialog box.
Read/Write: Saves batch read device values to the memory card as a recipe file and writes them to
devices as recipe values.
This option can only be configured when Memory Card is selected under Access to.
Read-only: Saves batch read device values to the memory card as a recipe file.
This option can only be configured when Memory Card is selected under Access to.
Write-only: Writes recipe values to devices.
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 LDR 0000
LDR 0000-0 corresponds to channel 1-0, LDR 0000-1 to channel 1-1, through to LDR 0000-15
which corresponds to channel 1-15.

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