Modbus RS485,TCP/IP BACnet® RS485,IP,Ethernet

Web-enabled Network Centric

The EasyIO 30P Series Controllers are rugged, network centric, high performance multi-protocols Input/Output controllers to accommodate general and specific applications, featuring Modbus RS485, TCP/IP and BACnet® RS485, IP and Ethernet protocols plus a built-in Web server for easy configuration. EasyIO-30P can be configured to work as Bridge Controller without any compromise on its embedded I/O functionalities. Features: Web Browser Configuration

Built-in Web server enables configuration with popular web browser over an Ethernet connection. I/O status can be monitored over the Internet connection. Customized web pages can be hosted on the controller easily*.

Multi Protocols Support

Modbus and BACnet®* are supported on the same controller which provides flexibility for implementation.

High-Speed Data Rates Multiple serial communication (RS485) speed selection from 9.6kbps to 115.2kbps. Supports Ethernet 10Base-T and 100Base-T interface, half or full duplex.

As Bridge Controller The controller can be configured as Bridge Controller providing a network bridge for Ethernet and serial communication (RS485) via built-in protocol converter. This will reduce wiring cost, simplify network implementation and significant cost reduction.

Device ID

Complementing existing standard protocols, EasyIO-30P can be uniquely identified over the network. This facilitating online network device search and simplify reconfiguration.

Network Security

All configurations changes are protected via password setting, either through standard network protocol access (Modbus or BACnet®) or web browser.

Multiple Input/Output Type The controller has eight Digital Inputs, eight Analogue Input for current, voltage, resistance and temperature sensor, eight Digital Outputs (relay), four Analogue Output (current and voltage), and two isolated Open Collector outputs (with PWM control) for high speed switching.

High Accuracy Analogue Channels High speed 14-bits A/D converter with programmable gain amplifier yields a high resolution and accuracy reading on analogue input points. 12-bits D/A provides more accurate analogue output control.

Programmable/Standalone Functionality The controller can be configured to operate as standalone device. Over 40 types of programmable functions are available, typically thermostat, PID, scheduler, conversion, timer, utilities, totaliser and etc.

Online Help/Information All related information/helps are available through the controller web server. Information such as registers details, wiring diagram, device specification and etc are provided to assist the user.

Status Indicator Operational activity on each individual channel of DI, DO and Open Collector Outputs (PWM) are conveniently indicated by LED, so as the Power, Operation, Communication and Faults status.

Reset & Broadcast Switch A Reset Switch has been provided for system reset without power removal (Warm Start operation). The Broadcast Switch allows the controller to broadcast itself to the network during installation and implementation.

Online Firmware Upgrade/Configuration The controller firmware can be upgraded either through RS485 or Ethernet connection. Network communication and operation parameters can be changed via RS485/Ethernet with the built-in boot-loader and terminal program.

Data Logging

It supports data logging* for any controller variables.

IRDA Configuration and monitoring can be done via built-in IRDA* connection with Palm, Pocket PC and etc.

Robust System Operation

The controller has a built-in High accuracy Real Time clock with backup battery. Software and hardware watchdog timer are provided for high reliability operation.

Ease of Installation

All I/Os are connected via field removable terminal block connectors for easy maintenance. The controller casing fits standard DIN rail mounting.

EasyIO-30P Boot Loader

The EasyIO-30P Boot Loader is used to check firmware information and upgrade new firmware to EasyIO-30P. There are two ways to connect to EasyIO 30P Boot Loader.

1) RS485 Serial port. 2) Ethernet port (WINSOCK – TCP/IP).

It is recommended to use WINSOCK as the firmware upload speed is much greater than RS485 port. To activate the EasyIO-30P boot loader function, press and hold the ‘Service’ button while turning on the power, (or press and release the ‘Reset’ button with power online) and wait until the ‘STS’ blinks at fast rate (at about 5Hz), release the ‘Service’ button. RS485 Connection: Connect the EasyIO-30P RS485 to PC serial port via RS485-RS232 converter, open ‘HyperTerminal’ program (or others terminal program) with the following settings:

1) Baud rate = 115200bps 2) Data bit = 8 bits 3) Stop bit = 1 bit 4) Parity = None 5) Flow Control = None

Open HyperTerminal Select the Port Setup Parameters When connection is established, presses ‘ESC’ button the refresh the screen.

Login Screen Main Menu The default User Name is ‘admin’ and the password is ‘1234’. Select your choice when the main screen appears, follow the screen instructions to check and upgrade firmware.

The file download protocols used in EasyIO-30P are Xmodem or 1K Xmodem (faster rate).

For details operation please refers to User Manual. Ethernet (WinSock – TCP/IP) Connection: Connect the EasyIO-30P Ethernet and PC to the same network. The default EasyIO-30P settings are:

1) IP = 192.168.10.10 2) Subnet = 255.255.255.0 3) Gateway = 0.0.0.0 (not used) 4) Port Number = 23 (Telnet port)

If the default settings differ from your network, you can change these settings by using RS485 Connection or change your PC network setting in order to connect the device.

EasyIO-30P Terminal

EasyIO-30P Terminal provides a simple way to configure the EasyIO-30P with minimum hardware and software. It uses the existing RS485 connection and any dump terminal software. To activate Terminal program, open a connection using terminal software (e.g. HyperTerminal) using the following settings:

1) Baud rate = 19200 bps 2) Data bit = 8 bits 3) Stop bit = 1 bit 4) Parity = Even 5) Flow control = None

Open HyperTerminal Select Serial Port Setup Parameters Press and holds the space bar when connection is established, turn on the EasyIO-30P power and wait until the ‘STS’ LED blinks at fast rate (about 5Hz). Release the spacebar and the login screen will appear. The default login name is ‘admin’ and the password is ‘1234’. Follow the screen instructions for various settings. For details operation please refers to User Manual.

Coil Registers Binding (Holding Registers) Coil Registers Binding register’s address starts from 12288 (0x3000) of the Holding Registers plus the Coil Register offset. Refer to the Coil Registers for the offset. For instance, the Digital Output Set State Channel 1 address is 1, so the binding address should be 12288 + 1 = 12289 (0x3001).
