Sent by:
superordinate computer
The superior computer sends a keep alive message to the tightening controller. The tightening controller returns the
received message to the superior computer.
A communication timeout of 15 s (can be parameterized by the BS) applies to the tightening controller, i. e. if no
message is exchanged between the superior computer and the tightening controller within 15 s, the tightening
controller will believe that the connection has been disrupted and disconnect it.
Note:
We recommend sending a message (keep alive or other) to the tightening controller at the latest every 10 seconds
to avoid undesired connection disruptions (with high latency times with TCP/IP).
