Chapter 4. Configuration42 PACSystems* RX7i & RX3i TCP/IP Ethernet Communications User Manual GFK-2224QTerminals TabThis configuration tab (Figure 18) is displayed only when the Variable Mode property of the Ethernet interface isset to True. When Variable Mode is selected, the Ethernet Status bits are referenced as I/O variables. The I/Ovariables are mapped to the Ethernet status bits via this configuration tab.Figure 19: Terminals Tab Settings in Proficy Machine EditionThe use of I/O variables allows you to configure the Ethernet interface without having to specify the referenceaddresses to use for the status information. Instead, you can directly associate variable names with the statusbits. For more information, refer to “I/O Variables” in the PACSystems CPU Reference Manual, GFK-2222.
