2.1

Introduction

The OSI-S interface and OMM-S receiver are,

respectively, the machine interface and optical

receiver for use with the high-speed on-machine

contact scanning system for CNC machine tools,

an innovative high-speed analogue scanning

system that offers a new concept in part

measurement on machine tools.

The OSI-S manages data communications

between the components of the system and

the machine tool. Typically, it is mounted in the

controller cabinet so that it is close to the machine

I/O, from which it receives signals to synchronise

its operation with the running NC code. It is

connected via Ethernet to the controller’s PC front

end (or external data processor) to stream the

probe deflection data.

The OMM-S, which is powered directly by

the OSI-S, is designed to be mounted in the

machine environment and provide line-of-sight

communication with the OSP60 probe. When the

OSP60 probe is scanning, the stylus position data

is continuously streamed to the OMM-S. The data

stream is decoded by the OSI-S interface, where

it is buffered until requested by the software.

A second OMM-S can be connected to the OSI-S

to extend range, for example, in applications with

exceptionally long spindle travel; in applications

with rotating heads; or on large machines where

line-of-sight is difficult to maintain with a single

receiver.

The OMM-S can operate in one of four

transmission power levels that can be set within

the software. The power level of the OMM-S need

only be adjusted when it is likely that conflict could

occur from systems on adjacent machines.

Both the OMM-S and OSI-S use front panel

LEDs to provide a visual indication of their current

status.

All user-configuration settings of the OSI-S and

OMM-S, including optical transmission power

and I/O polarity, are adjusted using the scanning

software. No physical switches or adjustments are

required.

The OSI-S and OMM-S are only compatible with

the OSP60 probe, due to the sophisticated nature

of the optical transmission protocol.

The OSI-S is an interface that decodes signals

received by the OMM-S and controls the operation

of the OSP60 probe. It communicates with the

scanning software via Ethernet, and the machine

tool NC controller via I/O signals.

Status LED

The status LED shows four different conditions:

Off: No power.

Red: Power on, no Ethernet, outputs

disabled.

Green: Power on, Ethernet connected,

outputs enabled.

Flashing red: Solid state relay (SSR) output

overload.

NOTE: The status LED will start flashing red

when an output overload has occurred. All outputs

will be switched off. If this occurs, turn off the

power and remove the source of the problem.

Turning off the power will reset the OSI-S.

OSI-S with

OMM-S system

basics

OMM-S components

The OMM-S is an optical receiver that transmits

control signals to the OSP60 probe and receives

probe data signals for onward transmission to the

OSI-S and CNC control.

The OMM-S is for exclusive use with the OSP60

probe.

The following components are housed behind

the front window of the OMM-S (as shown in the

figure below):

• power LED;

• transmitter (Tx) LED;

• receiver (Rx) LED.

Power LED (red)

This LED will be lit when the OMM-S is plugged in

to the OSI-S and power is supplied to the OSI-S.

Do not remove the OMM-S connector from the

OSI-S before first removing the power.

Transmitter (Tx) LED (yellow) and

receiver (Rx) LED (green)

Both of these LEDs will light up when the probe

is switched on. The probe and the receiver are

continuously communicating to each other and

simultaneously transmitting and receiving.

These two LEDs will light up as long as there is

valid communication occurring. As soon as the

communication is interrupted, both LEDs will

switch off.

At the start of a probing cycle, both of these LEDs

will flash briefly when a probe switch-on command

is executed. Use this feature to help determine

which part of the system is at fault if a ‘probe

switch-on’ error occurs, i.e. if the LEDs do flash

then the probe is at fault and, for example, the

batteries may be dead.

In a tandem OMM-S installation, the LEDs on both

receivers will display the same state regardless of

which one is receiving the strongest signal.

NOTE: If the Tx and Rx LEDs flash together, the

OMM-S is in an overload state, remove the power

from the OSI-S (by powering down the machine

or removing the power connector) and reapply to

reset from this condition.

System

installation

Installing the OSI-S

The OSI-S is typically installed in the controller

cabinet at the rear of the machine tool. It can be

DIN rail mounted or it can be fastened to a panel,

using optional brackets and screws.

The OSI-S requires an I/O connection to the NC

from a Honda PCR series (28-way) connector

(not supplied). A pre-wired connector with 1.5 m

(4.5 ft) of cable is available as a spare from

Renishaw (part number A-5465-1600).

This I/O connection ensures synchronisation

of time-critical signals within the running NC

program.

Other signals that are not time-critical are

transmitted directly to the scanning software via

an Ethernet link to the controller’s PC front end (or

external data processor).

The Ethernet cable should be a CAT 7

specification screened cable with a maximum

length of 30 m (98 ft). It should be connected to

the controller’s PC front end (or external data

processor), using a dedicated connection, i.e. not

connected through a network hub. Connection

through a hub can cause critical data drop-out.

CAUTIONS:

Power supply voltage

Check to ensure the power supply does not

exceed 30 V between the power input (pin 1)

and the earth wire (green/yellow); the power

input (pin2) and earth wire (green/yellow); or the

power inputs (pins 1 and 2), as this could result in

permanent damage to the OSI-S and/or the user

power supply.

The power supply 0 V should be terminated at the

machine ground/“star point”. If a negative supply

is used (i.e. +ve terminal is at 0 V and -ve terminal

is at a negative supply voltage), the negative line

must be fused, rated at 1 A.

The use of in-line fuses at the machine cabinet is

recommended to provide protection for the OSI-S

and cable.

Output

Ensure that outputs from the OSI-S do not exceed

the specied current ratings.

NOTE: A good connection should be made from

the OSI-S earth tag to the machine ground

(“star point”).

System performance with the OSP60

probe

The OSP60 probe and OMM-S receiver may

deviate from the optical centre line, provided

that opposing light cones always overlap, with

transmitters and receivers in the other’s field of

view (line-of-sight).

Power levels for the OSP60 probe and OMM-S

receiver can be independently adjusted. These

adjustments are made during configuration of the

scanning software.

The probe power level can be reduced to optimise

battery usage, and the receiver power level can

be reduced to prevent interference with adjacent

systems.
