ModBUS-TCP Digital Interface Option Added to The New and Advanced Programmable DC Power Supply Series

TDK Corporation (TSE 6762) announces the introduction of the optional Modbus-TCP Digital Communication Interface to the highly popular GENESYS+™ Programmable DC Power Supply Series.

Adding to the already released optional IEEE (488.2 & SCPI compliant) Digital Communication Interface, and the three built-in standard Digital interfaces (LAN (LXI 1.5), USB (2.0) and RS-232/RS-485), the Modbus-TCP Interface is well-suited for Industrial Ethernet applications and allows the user to remotely program, measure and check status of the Power Supply by sending Modbus information using a TCP/IP protocol over a Modbus-TCP network.

With the GENESYS+™ Modbus-TCP Interface installed, there are altogether six different Power Supply operating modes available to the user. Those operating modes are via the Modbus-TCP Interface, the LAN Interface, the RS-232/RS-485 Interface, the USB Interface, the Remote Isolated Analog Interface or the Front Panel (Local) Interface. When either the Remote Isolated Analog Interface or the Front Panel (Local) Interface is active the Modbus-TCP Interface is still allowed to monitor the Power Supply functionality.

Using the Advanced Front Panel Display, the user can view the IP and MAC address, can set a complete IP Address, can perform a Modbus-TCP reset and can identify Remote operation by viewing a blinking REM indicator.

The rear panel offers a 2-port Modbus-TCP Interface which has two shielded Ethernet RJ-45 connectors and allows the connection of multiple Modbus-TCP power supplies in a daisy-chain without a network switch, with each Power Supply receiving its own IP address. Network status, Module status and Link/Activity indicators (LED’s) are provided to identify the Interface operation conditions.

An RS-485 Multi-Drop feature is also available which allows connection of up to 31 Power Supplies with a simple link cable using one Modbus-TCP IP address (shared by all RS-485 Power Supplies).

The GENESYS+™ Modbus-TCP Interface has the ability to communicate over any standard TCP/IP network including LAN (Local Area Network) and WAN (Wide Area Network), with PING server also being supported, and has a built-in webpage which allows the user to read and configure/modify the Ethernet configuration parameters, view Modbus-TCP statistics and verify communication with the Power Supply.

Also available are full remote Program/Monitor functions that are compatible with Modbus-TCP Test & Measurement utilities using the Modbus-TCP command language. Programming using TCP sockets, which support PLC’s, Linux and other non-VISA controllers, is supported with multiple and simultaneous socket (up to four) connections allowed by port 502.
