the changes to become active.
4.2.3
Safety in the network
Note
When the controller is connected to existing networks (e.g. to the Internet):
Unauthorised or inadvertent access to the controller could cause it to behave in an
unforeseen way.
Use the controller only in subnetworks that are protected against unauthorised
access from outside, e.g. through use of safety network components (special gate
ways/firewalls).
Use a password to make unauthorised or inadvertent access to the controller more
difficult (in the FCT: Menu [Component] [Online] [Password]).
4.2.4
Timeout
The controller recognises if the connection to the FCT software has been interrupted and then behaves
as parameterised in the FCT on the “Error management” page (malfunction number 0x32).
The typical timeout is 1 s, but can be longer in slow networks, since the timeout is adjusted dynamically
to the transmission rate.
