Chapter 1
POINT Guard I/O Overview
Distributed I/O communication for safety I/O data is performed through safety
connections supporting CIP Safety over an EtherNet/IP or DeviceNet network.
Data processing is performed in the safety controller. The status and fault
diagnostics of POINT Guard I/O modules are monitored by a controller.
In addition to I/O state data, the modules include status data for monitoring I/O
faults within each circuit.
The configuration information of the modules can be protected by a password.
1734-IB8S Digital Input Module Features
•
Safety digital inputs
–
Safety devices, such as emergency stop push buttons, gate switches, and
safety light curtains, can be connected.
–
Dual-channel mode evaluates consistency between two input signals
(channels), which allows use of the module for safety Category 3 and 4
and in applications rated up to and including Performance Level e/
SIL CL3.
–
Single-channel mode evaluates one input signal (channel), which allows
use of the module for safety Category 2 and in applications rated up to
and including Performance Level d/SIL CL 2.
–
You can configure a discrepancy time to control how long two channels
are allowed to be discrepant before a fault is declared.
–
An external wiring short-circuit check is possible when inputs are wired
in combination with test outputs. The module must be wired in
combination with test outputs when this function is used.
–
Independently adjustable on and off delays are available per channel.
•
Test outputs (digital input modules only)
–
Separate test outputs are provided for short-circuit detection of a safety
input (or inputs).
–
Power (24V) can be supplied to devices, such as safety sensors.
–
Test outputs can be configured as standard outputs.
–
Specific test outputs can be used for broken-wire detection of a muting
lamp.
1734-OB8S Safety Digital Output Module Features
•
Solid-state outputs
•
Dual-channel mode provides redundant control by using two output
signals (channels), which allows use of the module for safety Category 3
and 4, and applications rated up to and including Performance Level e/
SIL CL3.
•
Safety outputs can be pulse-tested to detect field wiring short circuits to
24V DC.
