Telecontrol techniques

Pleiger Electronics developed and produced telecontrol and transmission technique equipment and systems for more than 25 years. These, however, were exclusively marketed through one major electronics company. In this way for example the TP RF, TP26, TP26-K and TP26 KM telecontrol systems are successfully applied in many energy and water distribution companies as well as in industries. After these business activities with the major electronics company came to an end, Pleiger Electronics now not only supplies its telecontrol and automation systems on OEM basis as outside supplier, it also supplies directly to the end user and in connection with planning services.

Not only our detailed knowledge in the telecontrol technique sector and our continuing excellent contacts to end users of such systems form the basis for these activities, but also our process-oriented planning, the efficiency of which is proved every day in ship electronics and plant automation projects.
The main area of application of our telecontrol systems, also expressed in different terms as "area telecontrol", requires automation functions that increasingly exceed telecontrol functionality. These process-oriented functions are the area of experience in which Pleiger Electronics development and planning engineers are "really at home".

PMC 2000 our current remote control and automation systems
The first product announcement (middle of 2000), the first test installations (end of 2000), the first installations (beginning of 2001) and the first public presentation (Interkama 2001) brought our new PMC 2000 system entirely positive judgements.

Telecontrol and automation system PMC 2000

  • Compact
    Housing only
    157x123x113 mm
  • Modular
    8 to 80 inputs / outputs per unit
  • Cascadable
    Station enlargement via CAN bus, up to 14 units (up to 1120 E/A)


The basis of the PMC 2000 system is a small, compact unit in a rail mount housing made from VA sheet steel (dimensions:157x123x113 mm, W x H x D) with an intentionally limited number of inputs and outputs. By plugging a maximum of 5 input/output cards the type and number of the 80 maximum physical inputs/outputs are adapted to the requirements of the application.
If a larger number of inputs and outputs are required for applications, further units (maximum of 14) can be cascaded, i.e. be coupled via CAN bus. In this way PMC 2000 systems can be configured with up to 70 input/output cards (1120 info. points).

The power supply card (UE= 24V-DC or 60V-DC) with slot for the data transmission interface to supervisory level and the microcontroller card with efficient 16 bit processor, large memory areas for programme, data and parameters, a service interface as well as a slot for a CAN bus interface are part of the basic outfit of each unit.
The connection to the process is realised by plug-in input/output cards with digital and analogue inputs and outputs of different configuration. There is galvanic separation to the system of all inputs and outputs via optical couplers or relay contacts. With UE= 24 to 60 V-DC the digital inputs have an extended input voltage range. The digital outputs are suitable for 1, 1½ and 2-pole connection. Indicator LEDs are available on the front side for connection control purposes. Sampling or output of bipolar current or voltage values are made via analogue inputs or outputs respectively with multiplexed 12 bit A/D or D/A converters. For the connection of the process cabling screw/plug terminals or sub-D connectors are provided on the front side of the cards.

Interface sub-modules with standard interfaces RS-232 or RS-485 as well as modem sub-modules for transmission to switched lines (analogue or ISDN) or leased lines are available for the serial data transmission to process control level or also to external automation equipment or telecontrol systems.

Constituent part of every PMC 2000 system is the parameter controlled standard telecontrol software for processing 1 or 2 point information, bit strings, integrated totals, numerical values, measured values commands and setpoint commands. Data exchange to the supervisory level or to telecontrol systems is carried out in compliance with IEC 870-5-101, TP20/TP26 protocol or also as outside protocol as an option.

Configuration of the units and setting of the function parameters is carried out via integrated operation and diagnostic software or using the McService PC software with convenient graphical user interface. Presentation in various, function-related windows is carried out by mouse control and supported by software. Data storage in standard Excel CSV format additionally simplifies the system documentation.

As an option an efficient PLC function in compliance with IEC 61131 can be integrated into every PMC 2000 system. The process variables, such as 1 or 2 point information, bit strings, integrated totals, numerical values, measured values are transferred to the PLC as inputs by setting appropriate parameters and the PLC outputs switched to the digital or analogue outputs.

Programming is either carried out in the programming language sequence control (AS), instruction list (AWL), function plan (FUP), contact plan (KOP) or structured text (ST) on a PC or laptop with appropriate software support. Easy handling, short compile times and efficient additional functions distinguish the programming with the graphic and text editor. Commissioning is extensively supported by offline simulation and online test functions.

 

Application possibilities can be extended using the PMC 2000 telecontrol and automation system, for instance due to:

  • the compact design;
    simple subsequent installation also in switch cabinets already in existence,
  • the universal use;
    sub, central and head stations on identical hardware basis,
  • the modularity of the inputs and outputs;
    optimum requirement adaptation to the relevant process,
  • the possibility of cascading the units;
    from 8 to 1120 info. points subsequent extension also possible,
  • the flexible communication;
    in compliance with IEC 870-5-101, TP20/TP26 protocol, outside protocols,
  • registration of fast information and integrated totals;
    1ms registration time of 8 information/integrated totals each per unit,

and many more system and function features.

Identical hardware for sub, central and head stations is a distinguishing feature of the PMC 2000 system. As a result the variety of components is reduced in many applications and the burden of stockkeeping of spare parts is eased with a long-term effect.
