7.2 Network Diagnostics
7.2.1 Host information
7.2 Network Diagnostics
The status of the MELSECNET/10 remote I/O network can be checked by performing network diagnostics using GX
Developer.
When an error occurs, an error station can be identified with network diagnostics (host information, other station
information, network monitor details, and error history monitor). ( Page 75, Section 7.2.1 to Page 81, Section
7.2.4)
Network diagnostics can be performed to the remote master station and MELSECNET/H (MELSECNET/10 mode)
remote I/O station
*1
.
*1 To perform network diagnostics from the MELSECNET/H (MELSECNET/10 mode) remote I/O station, use GX
Developer of version 6.01B or later.
● The network diagnostic target is the network of the host station specified in transfer setup.
● When another station is specified in transfer setup, only the host information and other station information can be
checked by the network diagnostics.
● During the offline test, the network diagnostic information is not displayed correctly.
● To access the programmable controller on another station using the link dedicated instruction during the network
diagnostics, the execution of the instruction may be delayed.
Using the COM instruction, change the program so that the network diagnostics processing and the link dedicated
instruction are performed at the same time.
Remark
SB and SW areas listed in each table indicate the link special relay (SB) and link special register (SW) used for monitoring
items.
