An EtherCAT slave connection was developed for several devices that were previously connected via the CAN bus. An ARM core with an integrated EtherCAT slave controller from Infineon is used. The EtherCAT protocol offers a very high data throughput on an Ethernet basis, as the entire protocol processing is carried out in hardware. The integration of distributed clocks enables synchronisation in the µs range.

A circuit board has been developed for use as a remote control. The coupling takes place via a Bluetooth Low Energy connection. There are 4 buttons available for operation and information is displayed on a round 1.28" RGB LCD. Power is supplied by a LiPo battery, the integrated charging circuit is supplied via a USB-C socket. 6 RGB LEDs arranged in a circle enable the display of different operating states.

The IO board of the extruder control has been newly developed. Instead of the previous 7-segment display a modern colour display with a resolution of 320x240 pixels is used. The display has an extended temperature range of -20...70°C and a brightness of more than 500 cd/m². This makes it ideal for outdoor use. The entire user interface has been newly developed and extended.

UL certification has been carried out for 2 of our power controllers. This means that these devices can be used in the USA and Canada without any problems. Compliance with IEC 61010 (Safety requirements for electrical equipment for measurement, control and laboratory use) has been confirmed.

THAT WE WINS

As every year, we are supporting Aktion Mensch again this year.

As every year we support Aktion Mensch.

We are looking for hard- and software developers (m/f/d). If you can imagine taking on interesting positions in a small owner-managed company, please take a look at our job advertisements.

Finally the revised website is launched. The modern design is also easy to read on mobile devices. The information content of the pages has been significantly increased, as has the clarity. Convince yourself and browse through our website. The complete website is also available in English.

An AddOn board has been developed for the Raspberry-Pi to improve the combustion behaviour of a wood-burning stove. For this purpose, the exhaust gas temperature is measured with a thermocouple and the stove flap is moved accordingly so that the combustion process is optimal. Less wood is needed and the exhaust gas values are significantly better. Operation can also be carried out from a smartphone via a web interface.

Completion of the order development for the control of an extrusion welding machine for manual operation. We developed both the hardware and the software for the feed control as well as for the heating. The special challenge was the environmental conditions, e.g. the operation at an unregulated emergency power supply garden and accordingly a high robustness against distortions!
The controller is based on an ARM processor and also includes a control unit with buttons and display. The compact design allows it to be built as an integral part of the extruder.

In beautiful weather IEP celebrated its 30th birthday. The staff enjoyed the good food at temperatures of 25°C. After that, the rest of the day was free to fulfil the wishes of the customers with fresh energy in the new year.

Based on the CORE-5125 a controller for refrigerators was developed. In addition to the up to 4 high-precision temperature inputs, 3 digital inputs are available. Up to 10 outputs with 230 VAC / 16A are available for controlling the compressor and other units.
Updates can be carried out on site or log files can be extracted from the device via the USB port. An Ethernet connection or an RS485 interface allows several devices to be networked.
The touch screen and graphical user interface facilitate intuitive operation.
A potential-free alarm contact and emergency operation for 36 hours via a battery supply ensure alarming and recording of temperatures even in the event of a power failure.

800 MIPS at less than 1 Watt power: The CORE-5125 is designed as a plug-in module for a base board.
All core elements required for operation (power supply, RAM, FLASH, RTC ...) are available on the CORE-5125.
The numerous integrated peripherals (LCD, CAN, Ethernet, PWM, SD card, digital I/O, etc.) allow a wide range of applications without the need for external components.

After the revision of the MOCS5200, 2 Ethernet ports are available via an integrated switch. This makes it easy to implement line cabling. Power supply via Ethernet (PoE) is also possible.

With the CAN-AI8-16 analog input signals with 16-24 bit resolution can be acquired. There are 8 input channels available, 2 of which are always converted in parallel.

The MOCS5200 offers a performance leap with the PowerPC processor MPC5200. The processor runs with 400 MHz and has 128 MByte DDR-RAM and 32 MByte FLASH on the board.

A new processor module − the CORE-563 − has been developed for the IF555-3. With 8 MB RAM and Flash each, sufficient memory is available for the real-time operating system RTOS-UH and extensive applications.

The IF555-3 has been revised and is 33% smaller. The digital outputs can now switch any 0.4A, are suitable for inductive loads and protected against short circuits. The total current must not exceed 6A. The Ethernet interface can handle 100 MBit FullDuplex.

The relay coupling module with 8 channels is available for the IF555-3 or CAN-555. The module can be equipped with mechanical relays or solid-state relays, also mixed. One switch per channel is available for ON-OFF-AUTO, which makes installation much easier.

The universal CAN-555 board has been redesigned. The size could be almost halved, the internal computing power was significantly increased, so that now a better pre-processing of the measured values can take place.
There are also 16 digital inputs and outputs each as well as 16 analog inputs and 8 analog outputs available.

Development of the Real-Time Training Board (RTTB) for real-time training.

With the CAN-MIO the direct control of 230 Volt consumers is possible. 3 maintenance-free SS relays switch up to 800 W per channel. Temperatures can be measured directly via the integrated Pt100 inputs.
