(1) The 1768-ENBT communication module supports 32 TCP connections with firmware revision 1.x.
(2) The 1768-ENBT communication module supports 64 TCP connections with firmware revision 2.x or later.
(3) CIP connections can be used for all explicit or all implicit applications. For example, a 1756-ENBT module has a total of 128 CIP connections that can be used for any combination of connections.
(4) Total packet rate capacity = I/O Produced Tag, max + HMI/MSG, max. Packet rates vary depending on packet size. For more detailed specifications, see the EDS file for a specific catalog number.
