Mokka7/Snap7 is an open source, 32/64 bit, multi-platform Ethernet communication suite for interfacing natively with Siemens S7 PLCs. The new CPUs 1200/1500, the old S7200, the small LOGO 0BA7/0BA8 and SINAMICS Drives are also partially supported. Mokka7 is native port of Snap7 core written in pure Java (fork of moka7 http://snap7.sourceforge.net/) and parts of Sharp7.

Moka7 features:

• Native port of Snap7 core in pure Java, no DLL
• No dependencies with external libraries
• Packed protocol headers to improve performances

additional Mokka7 (fork) features (alpha state):

• DataTypes support (Bit)
• MultiVars Read/Write
• Enhanced API (Java8 required)

• Async non blocking read/write
• MultiVars as collections (automatic slit size)
