Yeah, I was wondering about

EMC only really understands digital signals, that is the problem. The
sensors you show have analogue outputs.
There are a number of ways to get analogue signals into EMC, but they
all involve some form of signal conversion. The simplest is probably a
voltage-frequency convertor IC

ok, i understand that i need to convert sensor's output of 0-10V to
digital signal. and i would prefer solution with lowest cost possible.
is Pixsys DRR 245 controller suitable for this purpose?
Not as far as I can see

+1 to the modbus+PLC solution
If you use a serial port, the rtai serial driver and an rs232-rs422
converter, you end up with a real-time modbus communication

Does EMC2 use the RTAI serial driver?

hello!
i have recently started getting familiar with EMC2 - it is wonderful
software, developers have my thanks and all the respect :))
i have been following this mailing list for few weeks and due to my
limited knowledge in CNC and computer literacy/programming now it is
time for me to ask a

New on 2.4 is a THC comp designed to work with the Mesa THCAD High
Isolation A-D Card. This card takes a 0-10v input and converts it to a
pulse that is read by the 5i20 encoder input. The velocity output goes
into my THC comp and controls the Z axis with offsets to maintain the
desired input.
