Installing tool and work probes on VMC

[sinha_nsit]

If a VMC with, say, 0i MC control has been purchased without any probes, and probes are desired to be separately purchased and installed on it, what is needed to be done?
Is Ladder modification also needed, or is it just a simple hardware connection between control and skip-signal receptor?
Does the probe supplier (say, Renishaw) do complete installation on the machine (irrespective of machine/control model), or is it users' responsibility?
If yes, is the cost of integration included in the cost of probes?
Is G31 a standard or optional code?

The ladder need to be modified! I dont think renishaw do installation...we bought a new machine and it our machine tool supplier that sold the probe system and install it! it was about 10k for renishaw wireless workpiece probing and tool measurement system installation include
