The enhanced, programmable I/O module has all the features of Tormach's own I/O module, but adds a built in programming language to perform more powerful I/I tasks asynchronously from your g-code program.
This module can co-exist on the same machine as Tormach's I/O boards, requires no modifications to PathPilot to work and provides a built in Forth programming language to give facilities similar to a built in PLC.
