Transmission Type K2 and K3
Transmission type K2 and K3 are time controlled.
If the transmission was triggered by remote request or manual/PLC trigger, the interval timer is restarted, and
the next transmission will be suspended for the set interval to avoid unnecessary data traffic caused by
remote requests or manual triggers.
• Transmission type = K2
When the time interval elapses, the message is always sent.
• Transmission type = K3
When the time interval elapses, the message is sent. However, if data has not been changed, it is not
transmitted.

The user interval set for the message is restarted every time the message is transmitted.
In case the transmission is triggered by a request message from the network or manual trigger (BFM #1280 to
#1284), the next transmission after externally/manual triggered message will not be sent in the former interval
"*1," but in the new interval related to the external/manual trigger event.
