13.5 Using Digital Input + FieldBus
The static unit as an option can be ordered with a FieldBus (Ex: profinet).
This option continuously writes the values on the unit keeping them up to date.
The external contact Sw
H
and the internal software contact Sw
S
are connected in series, therefore if you want
to enable the static unit, both contacts must be enabled.
Using the FieldBus it is possible to change the status of the Sw
S
contact with bit 2 of the “Command table”
(See the communication manual of the respective FieldBus), bearing in mind that the Sw
H
contact must also
be closed to enable it.
This configuration is useful for having an external contact for a safety or emergency alternative to the FieldBus.
NOTE:
The parameters written are:
• command table
• reference
• rescaling
if the FieldBus is active but disconnected these values will be forced to 0.
