TRAINING COURSES

image357

Our mission is to transmit the precise knowledge of the correct tool, which is directed to engineers, technologists, technicians and workers of companies in the different sectors from the industry and the electrical sector. In such form that they give to the society, competitive and trained personal that also are generators of solutions in all the companies that ask for it.

We have a great experience and trajectory in training the personnel in the telecontrol protocols, which allow the communication between equipments that are used in the electrical sector.

We offer training courses in the following telecontrol

Modbus

image359

 It is a communication protocol located at the 7th level of the OSI Model, based on the master / slave or client / server architecture, designed in 1979 by Modicon for its range of programmable logic controllers (PLCs). 

Turned in fact into a standard communication protocol in the industry, is the one that has the most availability for the connection of industrial electronic devices. The reasons by which the use of Modbus is superior to other communication protocols are:


  1. It is public. 
  2. Its implementation is easy and not requires much development. 
  3. It handles data blocks without supposing restrictions.  

Modbus allows the control of a network of devices, for example a measurement system of temperature and humidity that communicates the results to a computer. Modbus also is used for the connection of a supervision computer with a remote unit (RTU) in supervision systems of data acquisition (SCADA). Versions of the Modbus protocol, for serial and Ethernet port (Modbus/TCP) exist.

DNP3.0

English acronym, Distributed Protocol Network, in its version 3, is an industrial protocol for communications between intelligent equipment (IED) and controller stations, component of SCADA systems. It is widely used in the electrical sector.

The DNP3 protocol presents important functionalities that make it more robust, efficient and compatible than other older protocols, such as Modbus, with the counterpart to be a much more complex protocol.

The frame format used is based on the IEC 60870-5 specifications (it is a redefinition of this format, not an identical implementation), and makes use of the Cyclic Redundancy Check (CRC) for the detection of errors.

ICCP

image361

  

ICCP (Inter-Control Centre Communications Protocol) or IEC 60870-6/TASE.2 has been specified for utility of organizations worldwide, to provide an exchange of data over wide area networks (WANs) between control centers of services, regional control centers and others.

This protocol is based on the client/server principle. The transference results from a request to a control center (client) to another control center (server). The control centers can simultaneously be clients and servers. The ICCP is only one of the seven elements of the standard of seven layers of the OSI model, like so any physical interface, transport and network service that adjusts to this model are supported.

IEC 60870 – 5 - 101

image362

  

International norm prepared by the International Electrotechnical Commission Technical committee 57 for the monitoring of the energy systems, control systems and their associate communications. It totally compatible with the IEC 60870-5-1 and the IEC 60870-5-5 norms, its standard use is in series and asynchronous for the telecontrol of channels between DTE and DCE. The standard is suitable for multiple configurations such as point to point, star, multidropped, etc.

IEC 60870 – 5 - 103

image363

  

It is a norm developed by the International Electrotechnical Commission Technical Committee 57 for the control of the electrical system and associate communications. This one defines a complementary norm that allows the interoperability between the protection equipment and the control devices of a substation.

The device that fulfills this norm can send information through two methods. Either by the application of data specifying in an explicit form service units (Asdu) or the use of generic services for the transmission of all the possible information. The norm admits some specific functions of protection and provides the supplier of a service to incorporate its own protection functions in the ranks of private data. 

IEC 60870 – 5 - 104

image364

  

It is an extension of the IEC 60870-5-101 protocol with changes in the services of the transport layer , the network layer, the link layer and the physical layer, to satisfy the totality of the  accesses to the network. The standard uses the TCP/IP network interface to provide connectivity to the LAN network (Local area network) with different routers installation (RDSI, X.25, Frame relay, etc), also can be used to connect to the WAN (Wide Area Network).

The application layer IEC 104 conserves equal to the one of the IEC 101 with some of the data types and unused services. There are two link layers defined in the norm that are adapted for the data transfer through Ethernet or a serial line (PPP - Point-to-Point Protocol).  

Generally for the energy systems the IEC 104 protocol is used for the telecontrol center and the IEC 101 protocol is used for the remote interaction with the field.

IEC 61850

image365

  

It is a standard for the design of the automation of an electrical substation. The IEC 61850 is part of the International Electrotechnical Commission Technical committee 57. The defined abstract data models in IEC 61850 can be mapped in a series of protocols. 

The current mappings in the standard are MMS (Manufacturing Message Specification), GOOSE, SMV and soon the web services. These protocols can run over TCP/IP networks and/or substation LAN networks of high speed using the Ethernet commutation to obtain less than 4 ms of response for protection relays.
