Communications Cannot Be Performed Using The Ip Packet Transfer Function - Mitsubishi Electric NZ2GF-ETB User Manual

9.4.7
Communications cannot be performed using the IP packet
transfer function
Before troubleshooting the problem as listed below, execute the IP communication test and take corrective actions
according to the error code. ( Page 124, Section 7.3.6)
If the problem cannot be solved using the IP communication test, execute the actions listed below.
Checking
Does the Ethernet adapter module support the
IP packet transfer function?
When the IP address of the Ethernet adapter
module (Ethernet part) is the same as the
network address of the master station, is the IP
address (the third and fourth octets) of the
external device and Ethernet adapter module
(Ethernet part) within the setting range?
Is the IP address already in use?
Has a timeout error occurred in the IP
communication test?
Have the routing parameters correctly been set
in the master station and local stations?
Is the network number of the external device
side (the third octet of the IP address) the same
as that of modules and another external device?
(This applies only when the request source
external device, request destination external
device, and modules between them have the
same first and second octets of the IP address.)
• Check that bit 1 of Function check area of the own station (buffer memory address: 48
(30 )) is on.
H
• Check that the first five digits of the serial No. of the Ethernet adapter module is
14022 or later. ( Page 241, Appendix 11)
• Set the IP address that meets the rules in the external device and Ethernet adapter
module (Ethernet part). ( Page 108, Section 7.3.1 (1))
• Change the IP address of CC-Link IE Field Network in the master station so that the
IP address of the external device and Ethernet adapter module (Ethernet part) differs
from the network address of the master station.
• For the external device, set the IP address different from that of other devices on the
network, such as a CPU module, master/local module, and Ethernet adapter module.
• Disconnect the external device from the line and execute the Ping command to the IP
address of the disconnected external device. If a response is received even though
the external device is disconnected, the IP address is already in use. Change the IP
address.
Check "Relay Network No." in the routing parameters of the master station and local
stations.
• Check and correct the routing parameters of the master station and local stations.
• When the first and second octets of the IP address are the same for the request
source external device, request destination external device, and modules between
them, set the routing parameters so that the third octet of the IP address of the
external device is used as "Target Network No.".
• If a timeout error occurs in the IP communication test, enter the IP address in the
order of station from the closest to the device where the IP communication test was
executed. Repeat the test until which station can or cannot receive communications to
identify the error. ( Page 126, Section 7.3.6 (2) (b)) If the station causing the error
is found, check and correct the settings.
Change the network number of the external device side (the third octet of the IP
address) to the one different from that of modules and another external device.
