Using the Network Options
Ethernet Tester
5.1 Introduction
An Ethernet module may act as a client or as a server.
If it will be acting as a client -- that is, initiating transactions on the network for its
Quantum controller -- then you must program an MSTR block in ladder logic.
For details about the MSTR block, please refer to Chapter 3 on page 25.
The Ethernet module may also act as a server, responding to requests and
commands from devices on the network for its Quantum controller.
The Network Options Ethernet Tester utility allows you to get and clear statistics
and to read and write registers over the network, using a Windows-based PC.
You may also create your own program using the Ethernet module as a server. For
guidance in creating your own program, refer to Appendix B on page 65.
Note: In its capacity as server, the Ethernet module can only accept 20
connections at any one time. If a new connection is attempted and the server has
already reached its limit, it will terminate the least used connection in order to make
room for the new one.
