Flexible connection of RS485 devices with Profibus-DP-logic controllers (PLCs)
The Profibus gateway can be used to create a data connection between a Profibus master and produce an RS 485 field bus.
The exchange of data is set in a GSD (device master file).
This gateway provides a very transparent way, the connection between field buses. She is regarded as a dual-port RAM, which provides both sides shared data.
The read and write access is therefore always allowed.
Display and operation
On the front page can be found above the display for the data traffic, power supply and a fault indication.
Below you will find the switch for setting the address. (2 digits). This address is only
The connection to the Profibus is produced with known 9-pin D-sub connector.
On the slave side to the RS-485 bus uses one a 2-wire connection terminal connector.
Here the use of shielded twisted-pair cables is recommended.
