MTL 8215-DO-IS Instrument Transmission Module


The EBIM can be used with MODBUS TCP as remote I/O to another host system. When using MODBUS TCP, the EBIM acts as a Modbus Server communicating over Ethernet at speeds of 10/100MB. Combined with the PAC8000 Process I/OTM system components, it offers cost savings over control-room mounted systems as well as flexible system design and high system availability. A PAC8000 EBIM system can be used as a remote I/O node to any Controller which supports Modbus communication over TCP. When used in a Control system, all remote EBIM nodes are configured as if part of a local I/O system, providing a single integrated configuration of all I/O nodes in the system, whether local or remote.


The remote-mounted EBIM node is an ideal solution for all types of process applications, including the following industries: chemicals, petrochemicals, water, and wastewater, oil and gas (especially offshore applications), pipeline, power generation, electrical distribution, food and beverage, cement and pulp and paper.

Implementation of Data Communication on Simulation Platform
In the process of constructing a transmission system simulation platform, achieving fast and accurate communication of data within the platform is a key research topic, mainly solving the data communication between the EDPF-NT system and MATLAB. For security reasons, the database of the EDPF-NT system only allows reading and not writing. Therefore, the data communication between the EDPF-NT system and the MATLAB model needs to be implemented in three parts. Firstly, the real-time data of the EDPF-NT system is read from the engineer station and sent to the upper computer. Secondly, the MATLAB model reads the EDPF-NT system data sent to the upper computer. Finally, the data after the MATLAB model is run is sent to the EDPF-NT system through a COM card in the upper computer.

EDPF-NT system data reading
The data of the EDPF-NT system is stored in a specific format in the database and cannot be directly read or written. In order to facilitate users’ use of data, Guodian Zhishen provides NTClient.dll files that can be called by VC, VB, and other software. Users can read real-time data of the EDPF-NT system through the functions provided by NTClient.dll. This article uses VB to develop a program for reading EDPF-NT system data, and at the same time, uses Winsock controls to send the read data to the upper computer. This program is divided into three parts:
1) Declare the functions provided by NTClient.dll;
2) Read data from the EDPF-NT system;
3) Send data to the upper computer.
3.2 MATLAB’s call to EDPF-NT data

As the most popular simulation software currently, MATLAB plays an important role in the analysis and design of control systems. However, MATLAB itself does not provide a low-level communication interface, and other methods must be used to achieve data communication on the network. So the data sent from the EDPF-NT system engineer station to the upper computer is first received using a program written in VB, and then called through OPC technology.
