Abstract

A built-in analyzer controller including: a device controlling circuit for controlling the hardware of an analyzer; a network interface circuit for connecting the analyzer to a network; and built-in programs including a server program for performing a communication through the network interface using a predetermined communication protocol between the analyzer and an external terminal. The server program performs the processes of: sending information of the operating status of the analyzer to the external terminal on receiving a request for the same from the external terminal; and setting a control parameter of the analyzer using the device controlling circuit on receiving a request for setting the control parameter from the external terminal. Using the analyzer controller, the user can monitor and control an analyzer or analyzers connected to a LAN from a remote place, without requiring special programs, and at low cost.

Claims

1. A controller for an analytical instrument built in the analytical instrument, comprising:

a device controlling circuit for controlling the analytical instrument;

a network interface circuit for connecting the analytical instrument to a network; and

built-in programs including a server program for performing a communication through the network interface using a predetermined communication protocol between the analytical instrument and an external terminal,

wherein the server program performs processes of

sending information of an operating status of the analytical instrument to the external terminal on receiving a request for the operating status information from the external terminal,

setting a control parameter of the analytical instrument using the device controlling circuit on receiving a request for setting the control parameter from the external terminal, and

starting an analysis, halting the analysis and stopping the analysis on receiving a request for start, halt and stop respectively from the external terminal.

2. The controller for an analytical instrument according to claim 1 wherein the network interface circuit conform to the Ethernet standard (IEEE802.3).

3. The controller for an analytical instrument according to claim 1 wherein the server program performs the communication using the HTTP protocol.

4. The controller for an analytical instrument according to claim 1 wherein

the built-in programs further include a control program for controlling an operation of the analytical instrument using the device controlling circuit, and

the server program obtains the operating status information from the control program, and sets a new value of the control parameter to the device controlling circuit using the control program.

5. The controller for an analytical instrument according to claim 1 wherein the built-in programs further include an inter-controller communication program for enabling the controller to share the operating status information with another controller connected to the network.
