Troubleshooting for Each Phenomenon
This section describes troubleshooting for each phenomenon.
Perform troubleshooting for each phenomenon when the IO-Link module does not operate properly with no error. If an error
occurs in the IO-Link module, identify the cause of the error using the engineering tool.
Check the following items in the order from the top.
When the ON/OFF status of an external input cannot be read
When the ON/OFF status of an external output cannot be changed
If an external input cannot be read or an external output cannot be controlled even after the above actions are
taken, the IO-Link module may be failed. Please consult your local Mitsubishi representative.
Check item
Action
Is the LED (CQ LED or Q LED) of the
corresponding channels of the IO-Link module
turned on when the external input device turns
on?
If the LED does not turn on, there is a problem on the input wiring.
Check the wiring confirming that the input wiring is not disconnected or short-circuited, or the voltage of the
input signal is correct.
For details on the rated input voltage, refer to the following.
Page 21 Performance Specifications
Is the setting of the refresh device correct?
Check the refresh parameter and correct the setting of the refresh device so that it matches with the setting
in the program. For the setting of the refresh parameters, refer to the following.
User's manual for the master/local module used
Is Remote READY (RWr0.b11) on?
To enable reading the ON/OFF status of the external input when the module power supply is on, the initial
processing must be executed by using Initial processing request flag (RWr0.b8) and Initial processing
completion flag (RWw0.b8). Execute the initial processing to check that Remote READY (RWr0.b11) is on.
For details, refer to the following.
Page 143 Remote READY (RWr0.b11)
Connect the engineering tool to the master station, and then check that a data link is established in the own
station by using CC IE Field diagnostics. (
User's manual for the master/local module used)
Is any bit of Channel n (CQ/Q) short-circuit
detection flag (RX10 to RX1F) and Channel n
(L+) short-circuit detection flag (RX20 to RX27)
turned on?
If any bit of Channel n (CQ/Q) short-circuit detection flag (RX10 to RX1F) and Channel n (L+) short-circuit
detection flag (RX20 to RX27) is turned on, this means that an error such as short-circuit is detected on the
channel corresponding to the bit.
Check the wiring confirming that the input wiring is not disconnected or short-circuited, or the voltage of the
input signal is correct.
Check item
Action
Is the LED (CQ LED or Q LED) of the
corresponding channels of the IO-Link module
turned on when Channel n (CQ/Q) external
output signal 0 to F (RY0 to RYF) turns on?
If the LED turns on, there is a problem on the output wiring.
Check the wiring confirming that the output wiring is not disconnected or short-circuited.
Is the setting of the refresh device correct?
Check the refresh parameter and correct the setting of the refresh device so that it matches with the setting
in the program. For the setting of the refresh parameters, refer to the following.
