• 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)
