When the forwarding destination is set to “1: Buffer memory”
If the TRIG is turned from OFF to ON or the data corresponding to the trigger is changed, the next direct data is saved
in the buffer memory. When the data during operation is completed, operation of the buffer memory is automatically
started. One direct data can be saved in the buffer memory.
If the next direct data is written to the buffer memory, the DCMD-FULL output is turned ON.
During stopping or continuous operation, if the “Buffer memory” is specified, the data is not saved in the buffer
memory and rewritten to the next direct data immediately.
