SG4 Dongle

Ethernet Adaptor for SG4 Extended Light Curtain Series

ISTRUCTION MANUAL

SG4E: Safety Light Curtain of SG4 Extended series.
SG Extended GUI: Graphic User Interface for personal computer for SG4E

Series Light Curtains.

CLONING

SG-Dongle can download SG4E ACM configuration from SG4E then

upload it to other Light Curtains with same product code. That’s for backup
purposes in case of Light Curtain substitution after damage or series

configuration of several ESPEs with the same final function.

Step 1: Configuration Backup

Connect SG4-Dongle to source Sg4E as shown in Connection section of this
manual.

Hold

button till indication appears on display.

Backup is done when DL led stops blinking (Fig. 1)

Fig. 1 Configuration download procedure

Step 2: Configuration Restore

Connect SG4-Dongle to destination Sg4E as shown in Connection section of
this manual.
Important: destination Sg4E must have the same product code of source
one.

Hold

button till indication appears on display.

Restore is done when UL led stops blinking (Fig. 2)

Fig. 2 Configuration Download procedure

After a successful upload SG4-Dongle stores a configuration report and
shows the number of saved report.
A maximum of ten consecutive upload are allowed, then user must
download configuration reports by means of SG Extended User Interface.

After upload, configuration remains stored in SG4 Dongle: it’s possible to upload
the same configuration to other light curtains (a new report is generated for each
upload).

Step 3: Download report and check Light Curtain

configuration

Connect SG4-Dongle to Ethernet and Power as shown in Connection
section of this manual (cfr. SG4 Dongle Standalone Connection).
In SG Extended GUI Download all reports stored in SG4-Dongle

Each configuration reports shows the Light Curtain Serial Number which the
corresponding configuration has been uploaded to and all the configuration
parameters.

Carefully check all the configured Light Curtains are
operating according to downloaded reports before
restoring normal plant operation.

To erase not relevant or already downloaded Safery Reports hold
button till

indication appears on display.

OFFLINE CONFIGURATION

SG-Dongle can store SG4E ACM configuration from SG Extended GUI

then upload it to one or more SG4E Light Curtains compatibles with
configuration parameters. That’s useful for configuration of one or more SG4E
Light Curtains when no Ethernet connection is available on controlled
machinery.

Step 1: Store ACM configuration on SG4-Dongle

Connect SG4-Dongle to Ethernet and Power as shown in Connection
section of this manual (cfr. SG4 Dongle Standalone Connection).
In SG Extended GUI Choose “Safety System Configuration” to begin off-line
configuration.

Compose an SG4E System by dragging devices from catalogue with the
proper product code. (up to a 3 unit cascade configuration can be stored on
Sg4-Dongle)

Important: be sure to select the right SG4E product code according to
the device the configuration is going to.
A wrong selection will lead to a failure in device upload.

Step 2: Upload configuration to SG4E

Connect SG4-Dongle to destination Sg4E as shown in Connection section of
this manual.

Hold

button till indication appears on display.

After a successful upload SG4-Dongle stores a configuration report. A
maximum of ten consecutive upload are allowed, then user must
download configuration reports by means of SG Extended GUI.

After upload, configuration remains stored in SG4 Dongle: it’s possible to
upload the same configuration to other light curtains (a new report is
generated for each upload).

Step 3: Download report and check Light Curtain

configuration

Connect SG4-Dongle to Ethernet and Power as shown in Connection
section of this manual (cfr. SG4 Dongle Standalone Connection)
In SG4 UI Download all reports stored in SG4-Dongle

Each configuration reports shows the Light Curtain Serial Number which the
corresponding configuration has been uploaded to and all the configuration
parameters.

Carefully check all the configured Light Curtains are
operating according to downloaded reports before
restoring normal plant operation.

ERROR LOGGING

When connected to an SG4E System, SG4 Dongle can log light curtain
errors: detailed error information is saved on SG4 Dongle memory that can be
retrieved with the help of SG Extended GUI. That’s useful for diagnostic
purposes on randomic light curtains lockout.
Only ACM configured SG4E Systems can be logged.
SG4 Dongle saves one log item each time the connected SG4E System locks
into a noncritical Failure Lockout. Maximum number of Log items depends
from cascade topology: 7 items for 3 unit cascades, 11 items for 2 unit
cascades, 23 items for single unit cascade.
When SG4E Dongle is moved from one SG4E System to a different one
actual log is erased and a new log initialized. Same happens after a change
of SG4E System configuration.
Connect SG4-Dongle to Ethernet and Power as shown in Connection
section of this manual (cfr. SG4 Dongle Standalone Connection).
In SG4 UI Choose “Open Safety System Log form Device” to download and
visualize all Logs stored in SG4 Dongle.

Select SG Dongle device to visualize the contained “Safety system log”.
A Safety system log contains

 A Safety system report with detailed configuration of loggeg SG4E System
 One or more log item with detailed error information.

ADVANCED USER INTERFACE

When connected to an SG4E Light Curtain in operations, SG4-Dongle shows
detailed light curtain status information on 7-seg display.
See “Diagnostics” Chapter of SG4E Manual for more details about UI
messages.

ON-LINE MONITORING AND CONFIGURATION

When connected to both SG4E Light Curtain in operations and Ethernet
network, SG4-Dongle allows SG4 UI to directly connect SG4E Light Curtains.
Both single unit and cascade Sg4E systems can be monitored and configured
over Ethernet.
See Connection section of this manual for correct connection of SG4-Dongle
and SG4E Light Curtain.

Monitoring

In SG4E UI Choose “Monitor Safety System” to begin monitoring an SG4E
System with an SG-Dongle connected.

In monitoring section of SG4E UI user can obtain updated information about:

 Connected cascade topology
 All beam status
 Alignment level
 OSSDs status
 SG4E Inputs status
 SG4E Outputs status
 SG4E Working Mode (with detailed error information)
 SG Dongle Status

Monitoring is particularly useful for diagnosis and resolution of Light Curtain
problems.

Configuration

In SG4E UI Choose “Safety System Configuration” to begin on-line
configuration of connected SG4E.

After device selection follow guided “1-2-3” Configuration Steps to:

1) Select all configuration parameters

2) Write new configuration on Light Curtain and obtain the “Safety System

Configuration Report” required to test new configuration on Light Curtain.

3) Monitor Light Curtain operation before and after configuration.

Refer to Sg4E User Manual and Sg4E UI contextual help for further details
about configuration procedure and parameters selection.

Refer to Sg4E User Manual for all safety information and
detailed on-line light curtain configuration procedure.

Fig. 5 Stand-alone connection

TCP/IP CONFIGURATION

SG4 Dongle has DHCP client enabled by default. Then it’s usually sufficient
to connect SG4 Dongle to the plant network for SG Extended GUI to be able
to connect.
If connecting to a single PC outside a network configure the TCP/IP
parameters of the pc to match the following:

IP: 172.27.101.210
Netmask: 255.255.0.0

If necessary it’s possible to change SG4 Dongle Network Configuration from
SG Extended GUI in menu Device -> Setting after connecting SG4 Dongle.
