4.3.5 Online Connection: Ethernet
The FLOWSIC600 can be connected to a network via Ethernet with an according adapter.
This adapter translates the meter MODBUS communication (ASCII or RTU) to MODBUS TCP.
MEPAFLOW600 CBM supports the MODBUS TCP protocol.
b
Click the “Ethernet” button to establish a connection via Ethernet.
b
Specify the IP address of the MODBUS TCP adapter and the bus address of the meter in
the dialog “MODBUS TCP - MODBUS RTU/ASCII gateway settings” (
→
Figure 19) .
b
Click “OK” to establish an online connection to the meter.
Requirements
● The Ethernet connection requires firmware V3.3.05 or higher installed on
the FLOWSIC600, which provides the necessary Generic MODBUS protocol
on the RS485 interface.
● The FLOWSIC600 must be connected to a MODBUS ASCII/ MODBUS RTU to
MODBUS TCP adapter, which is connected to a network via Ethernet and
receives a - preferably permanent - IP address.
● The PC with MEPAFLOW600 CBM V1.0.46 or higher installed must be
connected to the network and have uninhibited access to this IP address.
Preparations for Online Connections via Ethernet
b
Make sure one of the serial ports (terminals 33/34 or 81/82) of the
FLOWSIC600 is configured to use Generic MODBUS RTU or Generic
MODBUS ASCII (NOT a SICK MODBUS protocol).
b
Connect a MODBUS RTU/MODBUS ASCII to MODBUS TCP adapter to the
serial port according to the manual of the adapter.
b
Connect the adapter cable to your network.
b
Make sure the network assigns a permanent IP address to the adapter.
b
Configure the adapter to the network settings (IP address / protocol /
baudrate / gateway etc.) that you want to use (refer to adapter manual).
b
Make sure the PC with MEPAFLOW600 CBM has access to the adapters IP
address.
b
Make sure you know the MODBUS bus address of the meter.
In case of problems with the network setup, refer to your network administrator.
