Set advanced browse settings of an Ethernet bus

Right-click an Ethernet bus in
RSWho
, select
Properties
, and click on the
Advanced Browse Settings
 tab.
In some circumstances, you may need to adjust these parameters based on your specific application and network topology:
  • Maximum number of TCP/IP connections used for browsing
     is the maximum number of TCP/IP connections that are used to browse this subnet. As a safe guard, RSLinx Classic limits the maximum number of TCP/IP connections used to 50 percent of the TCP/IP connection capacity of the CIP router. Note that your single-pass browse duration is a function of the number of expected nodes (as configured on the
    Configure Browse
     tab), the maximum number of concurrent requests, and the TCP/IP inactivity timeout value of the CIP router. If your number of expected nodes is less than or equal to the maximum number of concurrent requests, your single pass browse duration is limited to your Poll Timeout value. If your number of expected nodes exceeds your maximum number of concurrent requests, your single pass browse duration is: INT(number of expected nodes/maximum number of concurrent requests)*TCP/IP inactivity timeout. For example, for an EN2T device, the TCP/IP inactivity timeout is 2 minutes. If you have 300 expected nodes with the default maximum number of concurrent requests of 128, your single pass browse duration is approximately INT(300/128)*2 = 4 minutes.
  • Poll Timeout
     is the time RSLinx Classic waits for a response from an individual device when it is polled. The default value is 3 seconds. If you have a large number of Ethernet switches and CIP routers along the path from the computerrunning RSLinx Classic and the expected devices, you may need to increase the poll timeout value. The minimum value is the TCP/IP connection setup timeout of the CIP router.
