Part
Description
N
Ethernet Fieldbus port n. 1 with LEDs
O
Ethernet Fieldbus port n. 2 with LEDs
3.2.3 Sensor status LEDs
The LEDs are each dedicated to a sensor, and can display the following statuses:
Status
Meaning
Steady green
Normal sensor function and no motion detected in the monitored area
Orange
Normal sensor function and some motion detected in the monitored area
Flashing red
Sensor in error. See "Controller LED" on page 58
Steady red
System error. See "Controller LED" on page 58
Flashing green
Sensor in boot status. See "Controller LED" on page 58
3.2.4 Fieldbus status LEDs (Ethernet)
Note
: only if the controller supports the safety communication on the Fieldbus interface. For details, see "Safety Fieldbus
The meaning of the LEDs depends on the protocol in use. For details, refer to the proper safety Fieldbus
manual.
3.2.5 Inputs
The system has two digital inputs type3 (according to EN 61131-2). Each digital input is dual channel, and the
ground reference is common for all the inputs (for details, see "Technical references" on page 64).
When using digital inputs, it is mandatory that the additional SNS input "V+ (SNS)" is connected to 24 V dc and
that the GND input "V- (SNS)" is connected to the ground in order to:
l
perform the correct input diagnostic
l
assure the system safety level
The function of each digital input must be programmed through the Inxpect Safety application. The available
functions are the following:
l
Stop signal
: manages a specific signal to force all the safety outputs (detection signal 1 and detection signal
2, if present) to OFF-state.
l
Restart signal
: manages a specific signal which enables the controller to switch the safety outputs related
to all the detection fields that are free of movements to ON-state.
l
Muting group “N”
: manages a specific signal which allows the controller to ignore the information coming
from a selected group of sensors.
l
Activate dynamic configuration
: allows the controller to select a specific dynamic configuration.
l
Fieldbus controlled
*: monitors the input status through Fieldbus communication. A generic ESPE can be
connected to the input, respecting electrical specifications.
l
Acquisition Trigger
**: manages a specific signal which allows to use the Multi-controller Synchronization
(for details, see "Multi-controller Synchronization" on page 35).
Note*
: only if the controller supports the safety communication on the Fieldbus interface. For details, see "Safety Fieldbus
Note**
: only if the Inxpect Safety application supports the functionality.
For details about digital input signals, see "Digital input signals" on page 75.
3.2.6 SNS input
The controller also has an
SNS
input (high logic level (1) = 24 V) to check the correct functioning of the chip
that detects the status of the inputs.
NOTICE
: if at least one input is connected, the SNS input "V+ (SNS)" and the GND input "V- (SNS)" must also
be connected.
3.2.7 Outputs
The system has four digital OSSD short-circuit protected outputs that can be used individually (non safe) or
can be programmed as dual channel safety outputs (safe) in order to ensure the system safety level.
