Ethernet topologies
EtherNet/IP CIP Safety HarshIO IO module can be used with a protocol compliant scanner as part of control system architecture. The modules built-in 2-port Ethernet DLR capable switch allowing to use the network topology that meets the application needs. These topologies include the following:
Star  Daisy-chain  Combination of star and daisy-chain  DLR for Ethernet media ring redundancy
Star topology
Star topology allows to connect mixed I/O modules or additional devices. Performing maintenance on one module – for example, by removing the network cable, or by cycling power to the module – does not affect other modules.

24  IP67 Safety Digital I/O Modules
Daisy-chain topology
Daisy-chain ring topology is the easiest way to add more EtherNet/IP CIP Safety HarshIO IO module or additional devices in the system by daisy-chaining, or connecting each industrial device in series to the next.
This topology is the simplest and cost-effective solution because it takes full advantage of the dual port Ethernet switch integrated in HarshIO modules and reduces the overall Ethernet cable length.
Note!
When considering the daisy chain topology, note that:
Performing maintenance on any module not physically located at the end of the
daisy chain – for example, by removing the network cable, or by cycling power to the module – affects any modules located down the chain from the maintained module.
The embedded dual port Ethernet switch located in each module eliminates the
need for additional Ethernet switches

Combination of star and daisy-chain topology
Combining star and daisy-chain topology allows connecting EtherNet/IP CIP Safety HarshIO IO modules with mixed HarshIO modules or additional devices.

DLR Ring topology
DLR ring topology allows including mixed I/O modules and additional devices in a ring. Performing maintenance on one module – for example, by removing the network cable, or by removing a module does not affect other modules as the disruption can be detected and the CIP safety communication can be then routed adequately.

Safety States
The safety states of the HarshIO module are defined as the following:
Safe Outputs are switched OFF  Safe Inputs are reported in the OFF state on the network
Warning!
HarshIO modules are to be used in systems where the OFF state is the safety state.

Safety Inputs
Safety inputs are used to report the state of safety input devices.
A safety input can be configured as:
Not Used (default) - the input is disable and doesn’t participate in any safety function  Safety - the input participates to the safety function, but does not have a dependency on a test output  Safety Pulse Test - the input participates to the safety function and has a dependency on an
associated test output configured as “Pulse Test”
Standard - The input doesn’t participate in any safety function (allows to connect non-safe input
device). Nevertheless a Standard input behaves exactly like an input configured as Safety.
Using Safety Inputs on Single-Channel
The inputs are configured as 2 distinct safety inputs on the same M12 connector.
The process Input value is set to safety device physical input value and status is “1” (good) as long as no fault is detected. On fault detection, the process Input value is turned OFF and status is “0” (bad).
HarshIO behavior when used as single safe inputs:

Notes!
(1) When single channel input is configured as “Standard” or “Safety”, only internal
hardware faults can be detected. Input shall be configured as “Safety Pulse Test” to allow external short to ON detection.
(2) This state is a transitory state only as it corresponds to fault reset condition
(physical value set to OFF). If physical fault still exist on the wiring, fault will be detected again at next ON transition.

Using a Test Output
A test output can be configured as
Pulse Test – When the external contact of the safety device is closed, the test output pulse allows
diagnosing external wiring faults as stuck with the power supply or short with the other safety input from the same M12 connector.
Note! Characteristics of the pulse test
Pulse test length: 2ms  Pulse test period: 12ms
Note!
A pulse test can be configured to each safety Input of the M12 connector. It can be also associated to the both inputs.
Power Supply – The test output is used as a power supply to supply 24 VDC for the safety input
device.
Standard – The test output is used as a non-safe digital output.
Note!
No status led is associated to test outputs. Test output values and status can nevertheless be monitored via Inputs process image.
Muting Lamp – The test output diagnoses whether the circuit and lamp are operational.
Warning!
When test outputs are configured for Power Supply or Muting Lamp, the use of double isolation cable could be required depending on the application and on the expected SIL/CAT to achieve.
EtherNet/IP™ CIP Safety™ IP67 HarshIO 600
30  IP67 Safety Digital I/O Modules
When test output is activated, Muting Lamp feature controls the output current. Below 5mA, a fault is detected and the status is 0=OFF. Above 25mA is normal operation, the status is 1=ON.
Below is a typical scenario for muting lamp broken wire detection:
Test Output Process Value
Muting Lamp Physical State
Muting Lamp Status
Step #1: 1 = ON
Lamp good
1
Step #2: 1 = ON
Lamp broken
0
Step #3: 0 = OFF
Lamp broken
0
Step #4: 0 = OFF
Lamp replaced
1
Notes!
Only Test Output 3 and Test Output 7 can be configured in Muting Lamp
mode.
When Test Output is not activated, no broken wire fault can be detected.
However, once a default has been detected (step 2), the lamp replacement is diagnosed even if the Test Output is deactivated (step 3)
Broken wire detection is performed at a 3 second period. Two
consecutive detections are required before the status is reported as BAD, so up to 6 seconds can be required before muting lamp status to be set to BAD
