EtherNet/IP Conformance Test
EtherNet/IP Interface
*14 Large Forward Open (CIP optional specification) must be supported in order for 505 to 1,444 bytes to be used as the data
size. Application is supported between CS/CJ-series PLCs. When connecting to devices from other manufacturers, make
sure that the devices support the Large Forward Open specification.
*15 If the maximum number is exceeded, refreshing will require more than one CPU Unit cycle.
*16 When changing parameters, however, the EtherNet/IP port where the change is made will be restarted. In addition, a tim-
eout will temporarily occur at the other node that was communicating with that port, and it will then recover automatically.
*17 The EtherNet/IP port supports an IGMP client, so unnecessary multicast packets are filtered by using an Ethernet switch
that supports IGMP snooping.
