helo thr to communicate a CLX system with WW INOTUCH via RSLINX it is required to create an OPC topic in the RSLINX . go to OPC/DDE in RSLINX--> one browser will come up in that browser create a new OPC topic and make sure this new topic points to your CLX PLC. apply the changes done. then in WW INOTUCH create an access name as following:- node name = keep blank -- if you are using RSLINX on a local machine(this is recommended) or the name of the machine where RSLINX GATEWAY is installed application name = RSLINX topic name = the name of the OPC topic which you created in RSLINX the above explanation was for a standalone CLX PLC to communicate with INTOUCH if you are having a Redundant CLX PLC system then you will require the CONTROLLOGIX redundancy alias topic switcher , which is a small software which comes bundled with the firmware CD in your RSLOGIX bundle follow the same procedure for the redundant system but here you will create two OPC topics, one each for one CLX system. say you have created topics PLC_A and PLC_B. now go to OPC/DDE ----> ALIAS TOPICS in RSLINX and configure a new alias topic say PLC_SYSTEM add the two topics you have just created to the alias topic and make sure the check box "switch on command" is checked ,all other checkboxes(there are two more--i cant remember them) must be unchecked. now install the CLX redundancy alias topic switcher software as i told earlier open the Switcher software and here configure the three parameters as required one is the name of the alias topic(PLC_SYSTEM), second and third are the two OPC topics(PLC_A and PLC_B). make sure you activate the alias topic switcher ,there is one button to do this now in wonderware again you will do the same thing node name = keep blank -- if you are using RSLINX on a local machine(this is recommended) or the name of the machine where RSLINX GATEWAY is installed application name = RSLINX topic name = the name of the ALIAS topic which you created in RSLINX after this make sure you use this access name for all your tags and set the addresses properly for your tags do this and you are done NileshSURYA Sr. Project Engineer AB PLC PROGRAMMER nileshsuryarao@rediffmail.com Location :- MUMBAI
