Device Watch Mail:
When a device of the programmable controller meets a certain condition (see Example below), an e-mail
is sent to the designated destination.
Example:
Y0 turns ON or OFF,
DT0 is 100,
DT0 is equal to the value of WR0, or
the value of DT1 becomes larger than the value of FL0
Note:
When the status of the monitored device on the CPU unit changes in a short time, the ET-LAN unit may
-
not be able to detect the change.
As the number of monitored devices or the amount of connection communication increases, the interval
for monitoring devices becomes longer. Refer to the following calculation method to enable to surely
detect the change in the target device.
[How to calculate the interval of monitoring time]
When without the connection communication
Interval of monitoring time = 50 x N (ms)
-
If the conditions for device monitoring are satisfied when the power is supplied, a Device Watch Mail is
sent to the specified destination.
Ladder send e-mail:
When the e-mail send request flag in the shared memory turns ON, an e-mail is sent to the specified
destination.
The e-mail message, which is registered using the Configurator ET in advance, is determined by
specifying using the ladder program.
