  • Page 11: Chapter 3: Select Control Method

    CHAPTER 3: SELECT CONTROL METHOD A Variety of Control Methods power supply with MODBUS TCP interface is very flexible. In addition to the MODBUS TCP interface, there are other ways the supply can be used. Refer to USER MANUAL (IA761-04-02_) for more details on the local operation mode (Front Panel), Serial operation mode (RS232/485 or USB), LAN operation mode (Ethernet) or Analog (Via J1, DB26HD).

    3.2.2 Select RS232/485, USB (Serial) or LAN Remote Mode The serial (RS232/485 & USB) and LAN remote control may be selected even if MODBUS TCP option is installed. The serial and LAN remote modes are described in the USER MANUAL (IA761-04-02_). The MODBUS TCP has similar capabilities as the serial and LAN remote modes, but the MODBUS TCP programming language is not compatible with the serial or LAN languages (GEN or SCPI).

  • Page 15: Power-Up The Modbus Tcp Power Supply

    Power-up the MODBUS TCP Power Supply The power supply MODBUS TCP option automatically detects if it is connected or disconnected from a network. It automatically searches for a network server and receives or creates an IP address (set manually). It will also broadcast its IP address and hostname to all other devices on the network. 1.

  • Page 16: Hostname

    Hostname The hostname is an address in the form of name instead of IP address (i.e. G10-170). This address mode is less common than the IP address because the hostname cannot be viewed from the front panel, and because a naming service (such as NetBIOS or DNS) must be running on the network or the host PC. The default hostname has the following format: <...

  • Page 17: Chapter 5: Modbus Tcp Setup

  • Page 18: Modbus Tcp Reset

    To change the IP address: Press COMM button. Rotate Voltage Encoder until IP appears on the Voltage display, 1 appears on the Current display. Press Current encoder to enter IP configuration. Rotate Voltage encoder to view the IP address. Voltage display shows IP1-IP4 by rotating Voltage encoder. The Current display shows the corresponding IP address.

    CHAPTER 7: PROGRAMMING USING SOCKETS Socket Description MODBUS TCP offers socket connections. Socket is a low-level protocol that is universally available in all operating systems and programming environments.

  • Page 26: Chapter 9: Modbus Tcp Data Structure

    CHAPTER 9: MODBUS TCP DATA STRUCTURE Programming / Monitoring Values Translation MODBUS TCP communication interface preserves power supply resolution and accuracy, according to specifications. Programming / Monitoring values are represented in a form of 16 bits unsigned integer value. Rated Voltage, Current and Power (nominal values) are represented as 53620 in a decimal base or 0xD174 in a hexadecimal base.

  • Page 27: Data Type

    Char data type is used for strings represented as ASCII characters. Size of char is 1 byte. Char data type example - *IDN? query (address 3, 100 bytes, 50 registers) for 100 Volts, 50 Amperes power supply: TDK-LAMBDA,G100-50-MODBUS,12345-123456,G:02.000. Register Address...
  • Page 28 NOTES 1. * Last 0 is added as the initial register value is 0, this value is not part of the *IDN? string. 2. Always start register access from the first register address according to commands mapping table (refer to Section 9.7) for each command / query. Access to any other register won’t represent the actual data. For example for *IDN? query, always read from address 3.

  • Page 29: Data Access

    Data Access MODBUS TCP supports three types of data access operations: Read, Write and Read/Write. Query commands (registers) have Read access only. NOTES 1. Register which don’t have Read access return 0. 2. Write of an out of range value results in an error. It is recommended to read register 935 (SYSTem:ERRor? query) to verify no errors.
