C8 Controller Modbus

This manual is compatible with C8 controller firmware version x.x.x.4 and above (X – does not matter).
C8 controller supports Modbus RTU and Modbus TCP protocols. Both protocols are using main commands to read and preset registers. Supported Modbus commands are presented in Table 1.
Table 1. Supported Modbus commands

Modbus RTU protocol works via RS-485 interface. Default interface settings are presented in Table 2. Default in- terface settings and Modbus RTU protocol ID can be changed using the website. To change settings, connect air handling unit (AHU) to your network. Default AHU IP address is 192.168.0.60. Go to your browser and type default AHU IP address. You should see „Login“ window (Fig. 1). To login type username and password. Default username: „user“ and password: „user“.
Table 2. Default settings of RS485 interface

To find RS-485 interface settings and Modbus RTU protocol ID go to „SETTINGS“ and „CONNECTIVITY“ (Fig. 2). If you logged in, but can’t open „SETTINGS“ window make sure, that JavaScript in your web browser is enabled (activated).

If you can’t see „Login“ window, make sure that:

• your device and air handling unit are connected in the same network;
• your device and air handling unit are in the same subnet;
• your proxy server and firewall isn’t blocking connection;
• you typed correct IP address.

If your device is connected directly to C8 controller, make sure, that your DHCP server is disabled and your static IP is in same subnet. If you are using PC and Windows operating system, go to „Local Area Connection Properties“, go to „Internet Protocol Version 4 (TCP/IPv4) Properties“ (Fig. 3), check „Use the following IP address“ and type your static parameters, for example:

• IP address: 192.168.0.61;
• Subnet Mask: 255.255.255.0;
• Default gateway: 192.168.0.1.

The air handling unit has external connection terminals in the control box, inside the air handling unit. Modbus A and B communication wires can be connected to 1 and 2 terminals of connection for external elements (Fig. 4, Fig. 5). To connect devices use twisted pair cable. Maximum cable length is 150 m. C8 controller ground point (any GND terminal from connection too external elements – 4, 7, 10, 12) and other device should be connected together, if distance between the RS-485 interfaces is more than 10 m. (Fig. 4, Fig. 5).

Modbus TCP protocol works via Ethernet interface, connection is provided to RJ-45 socket on the C8 controller (Fig. 4). Default IP address is 192.168.0.60, and port is 502. To connect C8 controller via Modbus TCP make sure, that proxy servers or firewall isn’t blocking device destination IP address and 502 port is opened. Controller IP address can be changed using the website (Fig. 2). Instructions how to connect and login to website was presented at Modbus RTU section. IP address and subnet mask also can be changed using C6.1 touch panel. To find these settings click touch C6.1 panel screen, click „Menu“ button, click „Settings“ button and don’t release it, for more than 5 seconds, after that „Advanced settings“ window will pop-up. Click „Connectivity“ button and here you will find IP address and subnet mask (Fig. 6). If you want to change one of these parameters, just click on it and edit.

For connection the CAT5 category cable should be used. The maximum cable length between device and controller C8 is 100 m. C8 controller Modbus registers with descriptions are presented in Table 3.
