■Diagnosis of IO-Link master unit data
The EX600 IO-Link master unit secures the diagnostic function in each port, communication is performed
with LED display and process data input (PQI) in accordance with the diagnostics.
The LED display, PQI and even code of each diagnostic are shown below.
Port diagnostics function
PQI
Bit No.
(Description)
L+ short circuit detection
Pin No. 1-3 short circuit diagnostics
P24 short circuit
detection
Pin No. 2-5 short circuit diagnostics
Pin No. 1-4 or 3-4 short circuit diagnostics
Connected device
matching error
When the port operation mode is IO-Link, the
communication port in which "matching level
of connected device" parameter is set to
"Type Compatible" matches the registered
Vendor ID, Device ID and the value read
from the connected device, and if they are
not matched, an error is diagnosed.
Device process data
mapping error
1
When the port operation mode is set to
IO-Link, if a device in which the process data
length is longer than the mapped data length
is connected, it will be diagnosed as an error.
Device disconnection is
detected
2
When the pin function / operation mode is set
to IO-Link, device disconnection is detected.
P24 power supply
reduction
Power supply reduction of class B type Pin
No. 2-5 is diagnosed.
1: Under the mapping error, all of the process data input and output are zero.
2: When Device disconnected is detected at port, all of the process data input is zero.
Note) Diagnostics other than the short circuit detection (L+, P24, C/Q) are not handled as the EX600
diagnostic data, so check for the LED display and PQI of the IO-Link master.
