Assign IP Mode: Manual Assign, BOOTP and DHCP optional, default value is manual assign;
Check unit ID: open and close optional.
Unit ID (1~255): valid when “Check unit ID” is opened, 1~255 optional.
Scan rate: the ratio of slow scan cycle and fast scan cycle.
Network status indication: mutual surveillance of both ends, PROFIBUS DP monitors the network state of
Modbus TCP, Modbus TCP monitor PROFIBUS DP network state and no indicating optional.
Modbus TCP master read data function code: "04H read the data DP sent to the Ethernet, 03H read back the
written data","03H read the data DP sent to the Ethernet, 04 read back the written data" is optional. Among them:
"04H read the data DP sent to the Ethernet, 03H read back the written data" means that Modbus TCP master is
using the 04H function code to read the output data from the PROFIBUS DP master to the Ethernet side, the use
of 03H read back the written data of the PROFIBUS DP master; "03H read the data DP sent to the Ethernet, 04
read back the written data" means that Modbus TCP master is using the 03H function code to read the output data
from the PROFIBUS DP master to the Ethernet side, the use of 04H read back the written data of the PROFIBUS
DP master.
The first address of read-only register (data direction: DP to Ethernet): range 0 to 65535, default value of 0;
The first address of the read/write registers (data direction: Ethernet to DP),: range 0 to 65535, default value
of 0.
6.4.3 Node Configuration Interface
In the equipment view, click on the Ethernet, the protocol type is Modbus master, right-click on the
"Ethernet", adding new nodes, the node configuration view interface displays the following:
