1.12 Logging Function
Level trigger
When a value in the monitored buffer memory area of the A/D converter module satisfies a preset condition, a hold trigger is
generated.
A level trigger is monitored on the refreshing cycle of the digital output value or the digital operation value.
Initial setting of a level trigger
■Setting a target to be monitored
As a condition to generate a hold trigger, set the buffer memory address to be monitored to 'CH1 Trigger data' (Un\G541).
To monitor a device value of a module other than the A/D converter module such as a device of the CPU module, set as
follows.
• Set a value between 90 and 99 (Level data (Un\G90 to Un\G99)) to 'CH1 Trigger data' (Un\G541).
• Write a value of the monitored device to Level data (Un\G90 to Un\G99) by using the MOV instruction.
Ex.
Application example of Level data (Un\G90 to Un\G99)
To monitor the data register D100 in the CPU module and operate the level trigger in CH1, create a program as follows.
1. Set 91 (buffer memory address of Level data 1) to 'CH1 Trigger data' (Un\G541) (when Level data 1 is used).
2. Store the storage data of D100 in 'Level data 1' (Un\G91) by the program continuously.
Specify an appropriate data such as 'CH1 Digital output value' (Un\G400), 'CH1 Digital operation value'
(Un\G402), or Level data (Un\G90 to Un\G99) to 'CH1 Trigger data' (Un\G541). When a setting area or a
system area is specified, the normal operation is not guaranteed.
Item Setting range
CH1 Trigger data (Un\G541) 0 to 9999
Item Setting range
Level data (Un\G90 to Un\G99) -32768 to 32767
