1.General

V-BOX and HMI support MODBUS TCP/IP protocol.

Modbus TCP Slave(ALll function):this protocol means V-BOX as master

Modbus TCP Master:this protocol means V_BOX as slave

Modbus ASCII TCP is same rule with Modbus TCP

2.Parameter Settings

First demo shows V-BOX as master communicate with HMI as slave.

2.1 V-BOX as Master

  1. Click [Configuration] in menu;
  2. Click [Communication],and add one new communication;
  3. Select[Ethernet]-->[Modbus] -->[Modbus TCP Slave(All function)].This protocol means V-BOX as master;
  4. Set a IP address(slave IP): for example 192.168.1.20

     5.Set V-BOX IP in network configuration.For example 192.168.1.10

Note: if V-BOX connect with internet by static IP.This static IP must set a DNS.Different country has different DNS.

Second demo shows V-BOX as slave communicate with HMI as master.

2.3 HMI as Master

  1. Click [communication] and add a new protocol “Modbus TCP Slave(All function);
  2. Set a slave IP:192.168.1.20

2.4 V-BOX as Slave

  1. Click [Configuration] in menu;
  2. Click [Communication],and add one new communication;
  3. Select[Ethernet]-->[Modbus] -->[Modbus TCP Master].This protocol means V-BOX as slave;
