ProData II
Modbus gateway
The ProData 2 can be set as a Modbus gateway with
the following limitations:
• In this mode, the ProData 2 cannot be used as a
Modbus RTU slave device.
• In this mode, the ProData 2 converts Modbus TCP
packages from port 502 (only TCP) to Modbus
RTU and sends these via the RS485 interface.
If a response is received via the RS485 interface
within a timeout period that can be set, this is
converted to Modbus TCP again and sent via
the IP connection.
• The ProData 2 can only forward queries (e.g.
from the GridVis software) to a Modbus slave
device. It
CANNOT query Modbus slave devices
independently.
Fig.: Connection variant with ProData 2 as a gateway.
The ProData 2 converts the queries of the GridVis
software (TCP packages via Ethernet) for the Modbus
slave devices (Modbus RTU) and forwards these via
the RS485 interface (RS485 mode: Gateway; Addr. 3=1).
