7.4.4 Precautions
Precautions for using the monitor transmission function are explained below.
(1) The device/status for transmission trigger storage is monitored at the interval
designated with the buffer memory monitor interval time designation (
R2
70H).
The ON/OFF status, value, status state that act as the transmission trigger
generation condition must be held for longer than the monitor interval time
(+100ms).
If the ON/OFF status, value, status state that act as the transmission trigger
generation condition are not held for longer than the monitor interval time, the R2
may not detect the transmission trigger.
(2) If the monitor transmission process and other transmission process (non-
procedural transmission/frame transmission) are overlapped, the R2 will transmit
the transmission data in order of transmission process generation.
(Example) If a monitor transmission trigger is generated while the R2 is carrying
out non-procedural transmission/frame transmission, the monitor
transmission will be carried out after the non-procedural
transmission/frame transmission process is completed.
(3) If multiple monitor transmission triggers occur simultaneously, the monitor
transmission will be carried out in order of transmission trigger detection.
