15 Fieldbus
Fieldbus communication can be used for data communication between Power Focus and a
PLC (programmable logic controllers). It is an effective and fast way for the data transfer of
short data packages. Fieldbus is normally used to send discrete I/O data instead of using a
large number of cables that have to be hard wired to relays and digital inputs.
There are many different fieldbus standards on the market and they all have different hardware and
software protocols. To be able to communicate on the fieldbus, Power Focus must be equipped with a
specific card for the preferred type of fieldbus.
Power Focus acts as a client in a fieldbus system. A PLC or similar acts as the reference
(master).
This section includes screenshots from ToolsTalk PF. The screenshots show examples of
parameter settings and are NOT intended to be generally applicable. Check with your
local Atlas Copco representative how to set up your specific system environment.
See section Digital I/O and fieldbus items for a description of all available fieldbus options.
With ToolsTalk PF, the fieldbus functionality in PF can be configured to fit the user-specific bitmap. It
also makes configuration or modification of a bitmap very easy. When the configuration is done, it can
be downloaded to Power Focus or saved as a file for later use.
