Chapter 9 Errors and Remedies
9.4 Hint of WJ-PN and PROFINET
9.4.1 The order of turning on the power of WJ-PN and the
PROFINET IO controller
The order of turning on the power of PROFINET IO controllers and PROFINET IO devices isn't
defined in PROFINET. When both of a PROFINET IO controller and WJ-PN are turned on the power
and both of them are ready to PROFINET, they start to communicate of PROFINET. However, it may
take some time that a PROFINET IO controller prepares PROFINET. Please refer to the instruction
manual of the PROFINET IO controller for details.
9.4.2 Replacement of WJ-PN and WJ200 / WL200
When you replace WJ-PN and/or WJ200 / WL200, you need to set the device name
(NameOfStation) rightly. If you don't set the right device name (NameOfStation), WJ-PN doesn't
communicate.
When you replace WJ-PN, you need to set the device name (NameOfStation) the same setting of old
WJ-PN with an engineering tool.
When you replace WJ200 / WL200, you need to set the inverter parameters the same setting of old
WJ200 / WL200.
When you replace WJ-PN and WJ200 / WL200, you need to set both of them.
If WJ-PN doesn't start to communicate by PROFINET after the replacement, please confirm the
PROFINET cable is connected right and turn off and on WJ-PN and WJ200 / WL200.
9.4.3 The initialization and the mode change of WJ200 / WL200
You can initialize and change the mode of WJ200 / WL200 even if WJ-PN is communicating. When
you initialize or change the mode while WJ-PN communicates, WJ-PN keeps communicating by
PROFINET. However, when you access the inverter parameters while WJ200 / WL200 is initializing,
WJ-PN returns the error code 0x65 of PROFIdrive.
You can initialize and change the mode of WJ200 / WL200 via PROFINET.
9.4.4 Network protocol analyzer
You can collect and analyze PROFINET communication log using a network protocol analyzer. It is
useful to investigate the unexpected phenomenon.
Recommended analyzers are the following.
