Email-Traps
Mail trap messages are automatically generated by industrial systems for information and status reports. Retrieved and evaluated by a

is no option to enter custom text or define a different recipient.

Tutorial: Email-Traps
Trap messages are a very popular way to automatically get information from a network. The concept provides that a device sends its
status in the form of a standardized data packet as soon as its current status changes. Among other things, the transmitted data
strongly depends on the device and its function.
the key feature of a trap message:
The type of transmission is unidirectional - the packet is sent and there is no acknowledgment of receipt. If the device can send the
packet, the task is completed. Since the messages are sent only in case of status changes, the destinated monitoring tool normally
assumes that the last received status received is valid.
Especially in weaker networks or in networks, where many messages of this kind are sent. This is an advantage as soon as either a
large number of devices have to be monitored or the network is poorly developed:
Both the required computing power and the amount of status data inside a network can be minimized.
