7.4
Protecting the service interface on the gateway
During operation, the label protecting the service interface and the DIP-switches must remain
in place due to EMC and ESD requirements.
7.5
Plugging and pulling electronics modules
XI/ON enables the pulling and plugging of XN standard electronics modules without having to
disconnect the field wiring. The XI/ON station remains in operation if an electronics module is
pulled. The voltage and current supplies as well as the protective earth connections are not
interrupted.
7.6
Extending an existing station
Attention
If the field and system supplies remain connected when electronics modules are
plugged or pulled, short interruptions to the module bus communications can occur
in the XI/ON station. This can lead to undefined statuses of individual inputs and out-
puts of different modules.
Attention
Please note that extensions to the station (mounting further modules) should be car-
ried out only when the station is in a voltage-free state.
