3.2 Network Parameter Setting
3
Arbitrary setting
Set the IP address type to [Setting from Tool] using the operation mode setting switches.
This enables arbitrary setting with the engineering tool, and the network ID has priority
over the value set with the host ID setting switches. This setting is done with connecting
RS-232C cables to EN7 module.
In using a redundant transmission path after setting the IP address type to [Setting from
Tool], set the subnet mask as follows.
Class B: 255.255.192.0
Class C: 255.255.255.192
Set IP addresses for the A-bus with the tool.
In using this setting, connect the system to the network after the setting.
(Ex. 1) Class B
In the case of network ID of 172.20.0.0 and station address (host ID) of 03h, IP
address is as follows. In this example, station address (host ID) range is 1 to 126.
A bus IP address: 172.20.64.3
B bus IP address: 172.20.128.3
The setting range is 172.16.64(128).xx to 172.31.64(128).xx (xx: station address
(host ID)). The third value of IP address is only 64 for A bus and only 128 for B bus.
(In the case of single bus, it is same to A bus IP address.)
(Ex. 2) Class C
In the case of network ID of 192.168.32.0 and station address (host ID) of 03h, IP
address is as follows. In this example, station address (host ID) range is 1 to 62.
A bus IP address: 192.168.32.67
(67 = 64 + 3)
B bus IP address: 192.168.32.131 (131 = 128 + 3)
The setting range is 192.168.0.64(128)+xx to 192.168.255.64(128)+xx (xx: station
address (host ID). The forth value of IP address is 64+xx for A bus and 128+xx for B
bus. (In the case of single bus, it is same to A bus IP address.)
• Download method of [Setting from Tool] mode.
(1) Connect engineering tool to EN7 module.
(Connect RS-232C cable to serial communication port (TOOL) of EN7 module.)
(2) Start up EN7 module in [Class B (General)] mode.
(Class B (General): set address type IP0 and IP1 of operation mode setting
switch to off.)
In this time, it is recommended that station address (host ID) switch is set to
minimum value of primary IP address which is going to set from engineering tool.
This prevents illegal operation at none existing station address "00".
Ex. IP address 172.20.64.22 case
Set station address (host ID) switch to "22".
(3) Display parameter setting window from configuration editor of engineering tool.
Select [comm. partner] (primary / secondary) in the parameter setting window,
and select [Tool (T)] in [View].
(4) Set IP address type, IP address, and subnet mask in the parameter setting
window. Select [Setting from Tool] at IP address type. After setting, save
parameters and register configuration information to engineering tool.
(5) Close parameter setting window and go back to configuration editor, save again.
(6) Download registered network parameters to EN7 module.
