5.3 Software Configuration
5.3.1 Configuration Software and its Function
There is a accompany software
”Ether_cfg.exe” to aid the configuration of
Ethernet module. This software is a windows-based software and has following
functions:
Basic module Information setup
- Includes IP (Network address),
gateway, netmask, baud rate, operating mode, module name, module
description.
Security setup
- Setup authorized IP. With this function, only the
command message issue by the host with authorized IP can be accepted
by Ethernet module. Hence can prevent the unintended access and keep
the system secure. There are 10 set of IP group can be set. Each group
can contain one or more consecutive IPs.
Local station to remote station mapping
- The operating of FBs-PLC
networking is purely transparent. When access the remote slave PLC by
executing the LINK instruction of mode0 and with the help of Ethernet
module, the master PLC does not know the remote PLC is connected by
network. In other words, the maximum number of slave station is still 254.
When Ethernet module work at client mode, in order to translate the local
station into remote station, must first setup the translation table.
Considering the convenience for variety application, there are three
methods can be used to setup the network configuration.
Setup by local area network
– This is the most convenient method for
network configuration. When operating, the configuration software will
scan all the Ethernet modules attached to the network. All the scanned
Ethernet modules will be shown in the table on the screen with the
regarded basic information. The user can pick the Ethernet module to be
editing directly from the screen. Considering the security, we can set the
password to prevent the unintended access. Please refer section 5.3.5 for
detail explanation.
