Diagnosis - SMC Networks EX245-EA2 Series Operation Manual

9.9. Diagnosis

The EX245-LA1 / LB1 has a diagnostic function for each port.
The diagnostics contents are displayed by LEDs and are assigned to the input process data as Port
Status (PQI).
For details of the PQI behaviour, refer to

∗1: When a mapping error is diagnosed the process data values for the Inputs and Outputs will be set to
zero.
∗2: The I/O process data values will be set to zero when the IO-Link device is not detected or has been
disconnected.
Note) Diagnostics for short circuit detection (L+, P24, C/Q) is duplicated in the PROFINET 'diagnostic
data on I/O mapping'. Refer to
Additional diagnostic faults are reported via the IO-Link module LED display and the PQI
diagnostic bytes for the EX245-LA1/LB1. Refer to

Pin No. 1 and 4 or 3 and 4 short circuit
diagnostics
A diagnosis check to confirm the Vendor ID
and Device ID of the connected IO-Link device
matches that in the configuration.
The following 2 conditions must be satisfied in
order to carry out the diagnosis check: -
a. Pin 4 (C/Q) mode in specified port of
IO-Link module must be set to IO-Link,
and
b. The port pin 'Validation & Backup'
parameter must be set to 'Type compatible
Device V1.x'.
A diagnosis error will occur when the port
operation mode is set to IO-Link and the port
receives exceed process data length than it is
configured for.
When the pin function / operation mode is set
to IO-Link, device disconnection is detected.
Power supply reduction of class B type Pin
No. 2 and 5 is diagnosed.
