Raspberry Pi CM3+ based mostly SBC ships with CODESYS

Kontron’s “Pi-Tron CM3+” controller SBC is predicated on the Raspberry Pi CM3+ and affords 2x LAN, 2x USB, 2x COM, 2x DIO, CAN, micro-HDMI, MIPI DSI/CSI, 40-pin GPIO, and CODESYS assist.

Since Kontron acquired PiXtend’s line of Raspberry Pi based mostly controllers a 12 months in the past, we now have been ready for some new Pi-based merchandise from the German embedded computing agency. Kontron has now delivered with the Baseboard BL Pi-Tron CM3+, a sandwich-style SBC constructed across the Raspberry Pi Compute Module 3+ (CM3+).

Like Kontron’s Raspberry Pi SBC based mostly PiXtend controller boards (see farther beneath), the Pi-Tron CM3+ helps the CODESYS automation software program for programming industrial controller purposes that adjust to the IEC 61131-3 industrial customary.

“Due to its open interfaces and complete safety features, CODESYS has distinguished itself as an optimum Trade 4.0 platform and facilitates knowledge alternate between any IIoT networks,” says Kontron. Different RPi Compute Module based mostly controllers with CODESYS assist embody TechBase’s ModBerry merchandise.

The wording of the Kontron announcement implies that the Pi-Tron CM3+ is already out there. We see no signal of a earlier announcement however we discovered this April 2021 article written by a Kontron exec about Kontron’s Raspberry Pi based mostly product line, which mentions the Pi-Tron and PiXtend merchandise.


Passepartout

The Raspberry Pi CM3+, which adopted the equally 1.2GHz, quad-core Cortex -A53 based mostly CM3 module used on Kontron’s earlier Passepartout (or Raspberry Pi Industrial Starterkit), provides 8GB to 32GB eMMC choices and affords a wider -20 to 70° working vary than the CM3. The CM3+ seems to be simpler to amass in quantity in comparison with the quad -A72 RPi CM4, which can be one motive why Kontron is utilizing it right here. The Kontron article linked to above says Kontron is engaged on creating CM4-based merchandise.

We've seen the CM3+ on a wide range of industrial controllers, panel PCs, and different methods, however that is the primary CM3+ based mostly provider and one of many few RPi Compute Module based mostly boards we will recall being promoted as an SBC. Just like the Passepartout, the Pi-Tron CM3+ is aimed toward industrial controller purposes and runs Raspberry Pi OS (Raspbian Linux).

The 105.5 x 67mm Pi-Tron CM3+ is smaller than the Passepartout. You may select from a wide range of 1GB LPDDR2 outfitted CM3+ choices from zero eMMC (CM3+ Lite) to 32GB. Kontron provides 16-bit FRAM, and should you select the CM3+ Lite, a microSD slot.

The Pi-Tron CM3+ is provided with 2x 10/100 Ethernet and 2x USB 2.0 host ports. For media, you get a micro-HDMI 1.3a port for as much as [email protected], in addition to 2-lane MIPI-DSI with touchscreen assist and a 2-lane MIPI-CSI interface.

Shoreline terminal plug interfaces seemingly specific the RS232, RS485, CAN, and 4x DIO (24 V/as much as 800 mA) interfaces. The 40-pin GPIO connector might be behind the opposite listed I/O: 2x UART, 2x I2C, 2x SPI, 28x GPIO, 2x PWM, and 4-bit SDIO. There may be additionally a console debug interface.

The Pi-Tron CM3+ supplies a 24VDC (±20 %) terminal plug enter and consumes 2.4W to 9.6W when working with out peripherals. Kontron touts the board’s “optimized passive cooling” at 0 to 55°C. There may be additionally assist for an RTC with battery.

 
PiXtend

Kontron’s PiXtend line of controller boards ship with CODESYS V3, in addition to the CODESYS internet visualization device and Node-RED. The controllers provide industrial interfaces that adjust to IEC 61131-3.

Kontron affords the PiXtend V2 -L- and smaller PiXtend V2 -S- controller boards plus an enclosed PiXtend eIO system that works with both. Primarily based on the photographs, the default PiXtend V2 -L- is predicated on the Raspberry Pi 3 Model B+ whereas the PiXtend V2 -S- makes use of the sooner RPi 3 Mannequin B. Nonetheless, the specs for each controller boards checklist assist for Pi fashions starting from the RPi 1 to the RPi 4.

The RPi 3B+ SBC has a sooner 1.4GHz clock fee for its quad -A53 block than the 1.2GHz Mannequin B and provides USB-based GbE with PoE assist and sooner 802.11ac WiFi. Raspberry Pi recently announced it was chopping again on its 3B+ manufacturing in favor of the RPi 3 and CM3.

The PiXtend V2 boards are touted for his or her 64 Byte EEPROM for retaining reminiscence of key knowledge towards energy failure, in addition to their means to manage and regulate brief cycle occasions: 5ms at 200Hz for the -L- and a pair of.5ms at 400Hz for the -S-. Different highlighted options embody “HighSide switches with separate feed and all-round safety,” together with 12x HighSide on the -L-.

The 236.3 x 101.8 x 27mm PiXtend V2 -L- affords extra I/O than the -S- mannequin, together with 16x DI, 12x DO, 6x analog inputs, 2x analog outputs, 4x GPIO, and 6x PWM/servo outputs. You additionally get CAN, RS232, and a Modbus RTU succesful RS485 hyperlink, amongst different I/O proven within the chart farther above.

The 166.3 x 101.8 x 27mm PiXtend V2 -S- affords lesser quantities of I/O and lacks CAN assist (see chart above). Just like the -L-, the -S-provides a 24VDC enter and a 0 to 50°C working vary.

The PiXtend eIO, which can be out there in a board-level product, “acts as a great complement” to the PiXtend V2 boards, says Kontron. The system affords an RS485 bus that helps Modbus RTU “and our lean PiXtend eIO ASCII Protocol.”

“Due to ultrafast HyperLogic, easy, logical hyperlinks between inputs and outputs could be applied by the modules themselves, eliminating the necessity to transmit knowledge by way of the bus system,” says Kontron. “The digital inputs can be utilized to rely occasions, which means that this course of doesn't need to be applied by way of software program.”

The system affords up/down and 2-channel counters impartial of the bus cycle. As much as 32 units could be operated as a single community/bus.

The PiXtend eIO is offered in Digital One and Analog Fashions. Instead of the 8x DO and 8x DI on the Digital One, the Analog One supplies a wide range of analog inputs and outputs, as proven within the chart above. The 106 x 105 x 45mm enclosed mannequin has a 24VDC enter and a 0 to 60°C vary.

 
Additional data

The Baseboard BL Pi-Tron CM3+ with CODESYS assist and the PiXtend merchandise seem like out there, with pricing undisclosed. Extra data could also be present in Kontron’s Pi-Tron CM3+ CODESYS announcement and Pi-Tron CM3+ product page, in addition to its PiXtend V2 -L-, PiXtend V2 -S- , and PiXtend eIO product pages.
