(a) Station No. <-> IP information setting system (conversion method)
There are four kinds of station No. <-> IP information setting system as shown below.
Conversion method
Automatic response system
IP address calculation system
Table exchange system
Combination use system
For details of each conversion method, refer to Page 39, Section 3.5.2.
(b) Net mask pattern
Specify the mask value based on the guidelines given below. This pattern is used in a logical sum with the own
station's IP address when calculating the IP address of the external device using the IP address computation
system.
• When setting the sub-net mask, specify the target settings of the IP address class, network address, and
sub-net address so that all bits are "1" in the mask pattern. The mask pattern is specified with a
decimal/hexadecimal value obtained by dividing the 32-bit mask value into 8-bit segments.
• When the sub-net mask is not specified, the mask pattern specification is not necessary. When the mask
pattern is not specified, the following mask value is used as the mask pattern according to the own station
IP Address class.
Class A
Class B
Class C
(c) Conversion setting (conversion information)
• The conversion setting is required to obtain the IP address from the network number and station number
using the table exchange system.
• When communicating between modules on Ethernet, specify network numbers, station numbers, and IP
addresses.
• Specify the network number in the range of 1 to 239 (1
to 64 (1
