Socket Interface Using CIP Generic Messaging 487
For details on specific services, see Socket Object Services on page 491.
Message Transfer Sizes
The maximum amount of application data you can send or receive
depends on whether you configure the MSG instruction as connected or
unconnected. The size of the application data does not include the
parameters in the Read and Write services.
For Read/Write service from/to TCP sockets, if the application data is
larger than the maximum size, you can issue multiple Reads or Writes to
receive or send the entire application message.
For Read service from UDP sockets, if the application data is larger than
the maximum size, you can issue multiple Reads to receive the entire
application message.
