TCP / IP connection problem

Hello, I cannot establish a Modbus TCP / IP connection between a NETBITER EC350 and a slave PLC.
Here is my configuration:
Netbiter -> WAN: 192.168.1.28;
NETMASK: 255.255.255.0;
DHCP. NETBITER -> LAN: 192.168.1.100;
NETMASK: 255.255.255.0;
NO DHCP Gateway ARGOS LAN -> MODE manually set fixed IP; IP address: 192.168.1.100;
Netmask: 255.255.255.0
PLC -> FIXED IP: 192.168.1.100;
Netmask: 255.255.255.0;
Gateway: 192.168.1.1;
DNS: 192.168.1.1;
NO DHCP
Can you tell me if my configuration is correct or if not what address should I give to the slave controller? The connection works in MODBUS RS485. Sincerely Florian.

Hello @Florian,

You will need to configure the LAN of the netbiter to be in a different subnet then the WAN. If the WAN is using a 192.168.1.0/24 Ip addres the LAN will need to be in a different subnet.

You can use the following:
Netbiter WAN: use DHCP assuming it will get an IP in the 192.168.1.x range
Netbiter LAN IP 192.168.2.100 Mask: 255.255.255.0
PLC IP address: 192.168.2.101 Mask:255.255.255.0
