NETWORK VARIABLES
zHeartbeat send time (Pr.388, Pr.389)
Pr. 388
Setting
Pr. 389
Setting
Operation
00
Sends data when data send event occurs.
* Network variables outputting data frequently (frequent changes) causes network
congestion. In such cases, adjust by setting Pr. 392 Event driven detection width, Pr.
388 and Pr. 389.
Other than 0 0
Checks presence or absence of data send event and sends data when an event
occurs. Sends data after the heartbeat send time interval (Pr. 388 setting) has elapsed
if there is no event.
0 Other than 0
Checks for presence or absence of data send event at interval of minimum heartbeat
send time (Pr. 389 setting). Sends data if an event presents.
Pr. 388 > Pr. 389
(Other than 0)
Checks for presence or absence of data send event at an interval of minimum
heartbeat send time (Pr. 389 setting). Sends data if an event presents.
Sends data after the heartbeat send time interval (Pr. 388 setting) has elapsed if there
is no event.
Pr. 388 ≤ Pr. 389
(Other than 0)
Sends data at an interval of minimum heartbeat send time (Pr. 389 setting)
independently of presence and absence of data send event.
REMARKS
• At power-on and inverter reset, data is not sent before the Pr. 387 Initial communication delay time (nciPwUpOutTm).
