How to use the ACE-GTW-MB
Mini WIFI Modbus RTU-TCP Gateway Router

Important

• Always switch on your ACE-GTW-MB Modbus gateway AFTER connecting your ACE PLC
• Information: Network > Interfaces : GREEN/RED colors = Firewall Settings (not CONNECTED/DISCONNECTED)
• Don’t forget: If you shutdow (OFF) your ACE-GTW-MB router then you shutdow (OFF) your ACE PLC if it powered by its USB port
• See with your security systems administrator for a safe configuration

Via its LAN RJ45 port connected to your network:

Connect the ACE-GTW-MB to:

• the ACE PLC with the mini-USB cable supplied
• your Ethernet network (or PC) with a RJ45 cable (LAN)
• the power supply with the micro-USB DC/DC converter cable
  • ACE PLC is powered by the ACE-GTW-MB via its USB port (except the ACE 7096)

Your ACE PLC is available via Modbus-TCP at the IP addresse http://192.168.8.1 (by default) and Ethernet port 502
You can also connect to the network configuration web pages: Login=root, password=root
Via the network configuration web pages, you can change: Password, Interfaces LAN/WAN, Wifi, DHCP, DNS, Hostnames, Static Routes, Firewall,..

Directly via the WIFI access point of the ACE-GTW-MB:

Disconnect the LAN port (RJ45)
Connect the ACE-GTW-MB to:

• the ACE PLC with the mini-USB cable supplied
• the power supply with the micro-USB DC/DC converter cable
  • ACE PLC is powered by the ACE-GTW-MB via its USB port (except the ACE 7096)

Connect your PC, Tablet, Smartphone,.. (Modbus-TCP Client) to:

• the WIFI access point “ACE-GTW-MB”
  • Your PC, Tablet, Smartphone,… must be in DHCP mode.

Your ACE PLC is available via Modbus-TCP at the default IP addresse http://192.168.8.1 and Ethernet port 502
You can disconnect from the LAN port (RJ45)
You can also connect to the network configuration web pages: Login=root, password=root
Via the network configuration web pages, you can change: Password, Interfaces, Wifi, DHCP, DNS, Hostnames, Static Routes, Firewall,..

Via its WIFI connection connected to your WIFI network:

First, you must be connected to the network configuration web pages of the ACE-GTW-MB.
See ” Via its LAN RJ45 port connected to your network ” above ^

In the network configuration web pages of the ACE-GTW-MB:

• In Network > Wireless/Wifi : Click on [ Scan ]
• [ Join Network ] you want to join
• Enter the passphrase/password if exist
• Let the name of the new network (wwan)
• Select a GREEN firewall-zone configuration (lan) and [ Submit ]
• [ Save & Apply ] the “Device Configuration” and “Interface Configuration” page
• In Network > Interfaces check the new IP address on WWAN interface

Your ACE-PLC is available via Modbus-TCP at the new IP address  and Ethernet port 502 (192.168.111.19 in our example on your right), which is automatically provided by the other DHCP server
You can disconnect from the LAN port (RJ45)
You can also connect to the network configuration web pages: Login=root, password=root
Via the network configuration web pages, you can change: Password, Interfaces, Wifi, DHCP, DNS, Hostnames, Static Routes, Firewall,..

Follow this steps (especially if you have already configured something in your ACE-GTW-MB):

First, connect the LAN port of the ACE-GTW-MB to a network with a DHCP server.
You must also be able to see which new IP address will have the ACE-GTW-MB.

In the network configuration web pages (http://192.168.8.1 by default) of the ACE-GTW-MB:

In Network > Interfaces: Click on [Edit] of the LAN network

• General Setup > Protocol > Chose “DHCP Client” > Click on [Switch protocole] then [Save & Apply]

Connect to the new IP adresse provide by your DHCP Server. (Its name is “Wifi” or “WTxxxx”)

In Network > Interfaces: Click on [Edit] of the LAN network

• Physical Settings >
  • Check “creates a bridge over specified interface(s)”
  • Check “VLAN Interface: eth0.1”, “VLAN Interface: eth0.2” and “Wireless Network” then [Save & Apply]

• In Network > Interfaces: Click on [Edit] of the WAN network
  • Physical Settings >
    • Check “creates a bridge over specified interface(s)”
    • Uncheck all Interface then [Save & Apply]
• In Network > Interfaces: Click on [Delete] of the WAN6 network

If you want, now you can come back to fix the IP address of the local network:

In Network > Interfaces: Click on [Edit] of the LAN network

• General Setup > Protocol > Chose “Static address” > Click on [Switch protocole] then [Save & Apply]
• Enter your new fix IP address and netmask then [Save & Apply]

<!> After, never plug LAN + WAN (2*RJ45) at the same time to the same network!
