Chapter 11. RX7i PLC Monitoring Via the Web206 PACSystems* RX7i & RX3i TCP/IP Ethernet Communications User Manual GFK-2224Q11.6 Viewing the RX7i PLC Web PagesEach web browser (HTTP) instance (i.e., each browse window) requires at least two TCP connections and eachFTP session requires two TCP connections to the PLC. The maximum number of web browser connections andFTP connections at the Ethernet interface at any one time are separately configurable from 0 to 16 (a value of 0means that the web server or FTP capability is disabled). The total number of configured web browserconnections plus FTP connections is limited to 16 connections; once the number of browser/FTP connectionsreaches the configurable limit, any new browser or FTP connection requests will fail.The number of Web Server and FTP connections is configurable via the Programmer. The Programmerconfiguration details are described in the Programmer Help utility.When the PLC is unconfigured, the user can change the number of web server (HTTP) connections and FTPconnections with the following Station Manager commands, respectively:CHSOSW web_max_conn CHSOSW ftp_max_conn As noted in the Ethernet Configuration section, the sum of web server connections plus FTP connections mustnot exceed 16 connections.For example:= CHSOSW web_max_conn 6= CHSOSW ftp_max_conn 4Note: The CHSOSW commands are not available if the PLC has received a valid configurationfrom the Programmer.
