Node.js

Another arrow in the quiver of Snap7 !!
Snap7 officially supports Node.js through the node-snap7 project.
Here you will find the wrapper source code and a detailed doc about its use.

Many thanks to Mathias Küsel, great Job !

Moka7 1.0.0 is out !!!

Pure Java port of Snap7, not just a wrapper.

• Only standard Java without any dependencies

·         Designed for small hardware and Android devices.

Freescale i.MX 6 QUAD + Atmel SAM3X8E (Arduino DUE).

To rebuild, as usual, simply type : make -f arm_v7_linux.mk install
from snap7-full-1.1.0/build/unix

Tested with the official Ubuntu distro.

Settimino is out !!!

The Snap7 porting (really rewritten) for ARDUINO.

• Full PLC memory access.
• PDU independence : large data transfer in a single call (depending on available memory).
• Helper functions for data conversion (Big Endian->Little Endian)
• Three memory models for memory footprint optimization.
• Uses Arduino Standard Ethernet library, i.e. it can coexist with other clients/servers in the same sketches.
• 4 ms to read an entire PDU (240 bytes) into the internal buffer.
• S7 200/300/400/WinAC/1200/1500 LOGO 0BA7.

Snap7 1.1.0 is out

- LOGO 0BA7 Ethernet support (as client/server and Network I/O blocks)
- S7200 (via CP243) experimental support
- New Callback for S7Server that allows writing full synchronous gateways (protocol translators)
- New rich-demos
- Some bug fixed
- Documentation inproved and updated.

Today was officially released Linux Ubuntu 13.10 (Saucy Salamander)
and Snap7 officially supports it (both 23/64 bit).

All demos/examples work fine without recompiling them.


No rebuild is needed, just use libsnap7.so from release/Linux/i386/glibc_2.17 or from release/Linux/x86_64/glibc_2.17

Raspy7-HMI

A very low-cost Open Source hmi panel built around Raspberry and a cheap LCD Display Kit.
User defined pages and tags, prebuilt full access to cpu static vars (E/A/MK/T/Z).

The Article and the documentation is in italian language..Sorry.

If someone is interested in it I can supply further infos.

Snap7 runs fine in Mele A2000 android video box (hacked with Ubuntu).

You will not find this port in the Snap7 release because Ubuntu is not the official OS for this equipment, but moreover because it's not properly an industrial hardware.

I made it just for fun and to further test snap7 build in the Arm context.

Snap7 runs fine in Ubuntu 13.10 (Saucy Salamander) final beta.


No rebuild was needed, I just used libsnap7.so from release/Linux/i386/glibc_2.17

Snap7 will be tested and officially supported in the final release (32/64) of this distribution.
