Transfer of data with the interrupt function
ON of High speed continuous logging data storage can be set as an interrupt factor of the interrupt function.
When the above item is set, the interrupt program is executed on the timing when the logging data for 10000 points are stored
in a buffer memory area. Thus, logging data can be transferred into file registers (ZR) without depending on the scan time.
For the interrupt program, do not use the function block for high speed continuous logging data transfer because the function
block does not operate properly by doing so.
■Program example to transfer data with the interrupt function
Ex.
To start the high speed continuous logging and copy logging data (CH1) for 100000 points and register them in file registers
(ZR0 to ZR99999) of the CPU module continuously
