Appendix A. Configuring Advanced User Parameters254 PACSystems* RX7i & RX3i TCP/IP Ethernet Communications User Manual GFK-2224QA-2 Advanced User Parameter DefinitionsNote: The RX3i CPE305/CPE310 embedded Ethernet interface does not support all AUPs listed.AUPs that can be used with CPE305/CPE310 are indicated by a footnote. OtherPACSystems Ethernet interfaces support the use of all AUPs listed in the following table.System Memory Parameters (task b) Default Rangestaudp26 Remote command UDP port 18245 (4745H) 1 – 65535 (ffffH)Only the gdata_portand gXX_udpparameters mayshare the same UDPport number. All otherUDP port numberparameters in the AUPfile must use uniqueport numbers.stpasswd26 Station Manager password (only visible from MODIFYprompt)“system” 0 – 8 characters, casesensitive, no spacesBackplane Driver Parameters (task c) Default Rangecrsp_tout26 CPU response timeout. Amount of time to wait for theCPU to respond to a request sent through the PLCDriver.60 seconds 10 – 3600 (E10H)chct_comp26 HCT compatibility option. (Rel 2.57 and later) AllowsEthernet interface to ignore SRTP header errors(typically generated by remote HCT devices) thatwere not detected in previous Series 90 products.0 = HCT compatibility disabled (= report all errors)1 = HCT compatibility enabled (= ignore some errors)0 (0H) 0, 1cstorm26 COMMREQ storm onset threshold. Establishes anumber of COMMREQs per second at or above whichthe PLC application is considered to be sendingCOMMREQs so rapidly that the Ethernet interfacecannot continue normal operation. Setting thisparameter to 0 disables COMMREQ storm errordetection.500 (01F4H) 0 – 10,000 (2710H)cnostorm26 COMMREQ storm end threshold. Establishes thenumber of COMMREQs per second at or below whichthe COMMREQ storm condition (see above) isconsidered to have ended. If the cstorm parameter isnot set to 0, this parameter should always be lessthan cstorm. If cstorm is set to 0, this parameter isignored.100 (0064H) 0 – 10,000 (2710H)RDS Parameters (task d) None None26 Supported by RX3i CPE305 and CPE310 models.
