PROFINET Device to Modbus serial protocol 
conversion

Manages up to 50 Modbus Read and Write 
commands

Serial  RS232 or RS485 switch selectable

 
Integrated 2-port Ethernet switch 

 
Up to 1000 Input bytes and 1000 Output bytes on 
PROFINET

Modbus Master or Slave (RTU or ASCII) protocols 
supported

Easy-to-integrate configuration by GSD file (no 
configuration tool needed)

Automatic configuration after each PROFINET PLC 
connection

Full diagnostics through face mounted LEDs

 
Commands are Cyclic, Change-of-State or Once-
Triggers

Enables connection between controller and devices

 
Maximizes capability. Minimizes costs through 
enhanced command capacity

Accelerates and simplifies configuration of the 
electrical interface

Permits Ethernet daisy-chain topology. Eliminates 
extra cost for a switch

Provides significant IO mapping memory

 
Allows the gateway to behave as a Master or Slave 
on the network

Eliminates the need for a configuration tool and prior 
experience in PROFINET technology

Eases replacement downtime 

 
Enables user to perform monitoring and diagnostic 
functions

Improves flexibility by enabling several I/O data 
exchange behaviours according to the user 
application
