    255.255.255.0 as a mask and address starting with 192.168.0. The fourth byte of the address can take any value in the range from 1 to 255, except for 111. If the connection between ET-485 and a client unit is not provided directly but via a network with a number of units, the mentioned address can not be equal to any of the addresses of other units on the subnet .
  • Page 18 Select "Use the following IP- address". Specify the address in the "IP- address" field within the range from 192.168.0.1 to 192.168.0.255 (except for 192.168.0.111, which is used by ET-485). Specify "255.255.255.0" in the “Subnet Mask” field. The fields "Default Gateway", "Preferred DNS-server", and "Alternative DNS- server" should be left blank.
  • Page 19 In case of complex and large networks (especially when providing access to the ET-485 via Internet), the users are recommended to separate the unit from unprotected networks with standard protective equipment (router, configured to filter the transmissions, Firewall, etc.).

    Two ET-485 units are used, connected as shown in Figure B.2. ET-485 “a” is connected in the slave mode to RS-485 Modbus “A” network (with a master device). ET-485 “b” is connected in the master mode with a static IP address to Modbus “B” network (with slave devices). Both units are connected into one Ethernet network or connected by means of routers via Internet so that unit “a”...
  • Page 21 At consecutive “chain” redirection, as shown in Figure B.4, every new ET-485 unit is set for redirection to the last added ET-485 unit in the chain (in the settings of which, in its turn, a new unit can be specified as the main client).
  • Page 22 If automatic sending of unique MAC address is enabled, after connection ET-485 shall transfer MAC address as Modbus response (herewith, query is not sent by the client). Then ET-485 awaits queries from clients as well as from other Modbus TCP clients. Since ACC mode is based on Modbus TCP with some changes (ET-485 connects the client and then functions as Modbus server), the client should maintain ACC mode.
  • Page 23 (herewith, Modbus write protection mode should be disabled). The user is offered once to enter the activation code of the necessary unit. The code is available for reading while ET-485 is being set through WEB interface. After the user enters a code, an appropriate unit is added to the list of user’s units.
