18.1 Troubleshooting Related to CC-Link IE TSN
When the slave stations to be used support
protocol version 2.0, is a master station that does
not support protocol version 2.0 used?
■When connected devices are protocol version
2.0
Is the event code 00C80 registered in the event
history?
■When connected
Is information on
devices are protocol stations that do not
version 2.0 support the protocol
Is '2: Operating with the version 2.0 stored in
protocol version 2.0' 'Station protocol
stored in 'Protocol version 2.0 support
operating status' status' (SW01A0 to
(Un\G1294016)? SW01A7)?
■When connected
Is information on
devices are protocol stations that do not
version 2.0 support the protocol
Is '1: Operating with the version 2.0 stored in
protocol version 1.0' 'Station protocol
stored in 'Protocol version 2.0 support
operating status' status' (SW01A0 to
(Un\G1294016)? SW01A7)?
Are nine or more CC-
Link IE TSN Class B
devices and TSN hubs
connected in total to
each port of the master
station in the
transmission path from
the master station to
the CC-Link IE TSN
Class B device of the
end?
Does the cyclic data
size exceed 2K bytes in
total for CC-Link IE
TSN Class A devices
connected to a CC-Link
IE TSN Class B device
except for the master
station? (Including
when a CC-Link IE TSN
Class B device is
connected via a
general-purpose hub)
■When connected devices are protocol version
2.0
Is there any difference between the CC-Link IE
TSN Class B/A mixed system configuration and
the "TSN HUB Setting" in "Connection Device
Information" under "Basic Settings"?
Action
Update the firmware of the master station to a version that supports protocol
version 2.0. Alternatively, replace the master station with a master station that
supports protocol version 2.0.
Take one of the following actions.
• Check 'Station protocol version 2.0 support status' (SW01A0 to SW01A7),
and update the firmware of all the slave stations to a version that supports
protocol version 2.0. Alternatively, replace the slave stations with slave
stations that support protocol version 2.0.
• For firmware version "02" or later, set 'Protocol setting' (Un\G1294018) of
the master station to '1: Protocol version 1.0 fixed'. ( Page 477 Protocol
information (Un\G1294016 to Un\G1294031))
• After powering on the slave stations and the devices on the communication
path, power on the master station.
Take one of the following actions.
• Check 'Station protocol version 2.0 support status' (SW01A0 to SW01A7),
and update the firmware of all the slave stations to a version that supports
protocol version 2.0. Alternatively, replace the slave stations with slave
stations that support protocol version 2.0.
• For firmware version "02" or later, set 'Protocol setting' (Un\G1294018) of
the master station to '1: Protocol version 1.0 fixed'. ( Page 477 Protocol
information (Un\G1294016 to Un\G1294031))
• After powering on the slave stations and the devices on the communication
path, power on the master station.
Check 'Station protocol version 2.0 support status' (SW01A0 to SW01A7), and
update the firmware of all the slave stations to a version that supports protocol
version 2.0. Alternatively, replace the slave stations with slave stations that
support protocol version 2.0.
Check the connected devices and reduce the number of CC-Link IE TSN
Class B devices and TSN hubs to eight or less in total for each port of the
master station in the transmission path from the master station to the CC-Link
IE TSN Class B device of the end.
• Connect to CC-Link IE TSN Class B devices via NZ2MHG-TSNT. (When
connecting via a general-purpose hub, change the general-purpose hub to
NZ2MHG-TSNT.)
• Restrict the number of connected stations so that the cyclic data size of the
CC-Link IE TSN Class A devices does not exceed 2K bytes in total.
• Connect the CC-Link IE TSN Class A devices to the master station.
