PdL Posted January 16, 2007 Report Posted January 16, 2007 From PM this afternoon: Hi Gorinchan, and welcome to MrPLC.com! CX-Programmer itself is not suitable to use as middleware to connect to a SCADA system. What to use instead all depends on the communication method to your Omron PLCs. I have looked at the available drivers for Adroit, which are serial and Ethernet FINS UDP. Both drivers do not need any middleware to communicate to the hardware. Which one do you use ? What CPU type ? Please reply in this topic, so everyone can reply and benefit. Quote
gorichan Posted January 16, 2007 Report Posted January 16, 2007 Thanks for da reply. Im just using RS232 to connect between the computer and the PLC. The PLC type is CQM1H CPU41 type. Question: What do you mean by 'middleware' ? Is it like OPC Server or something? TQ Quote
PdL Posted January 16, 2007 Author Report Posted January 16, 2007 Yes. Because you were asking to connect CX-Programmer to your SCADA, I asumed you were thinking your SCADA can't connect to the PLC directly and needs a 3rd party software. But this isn't the case so your want to connect your PLC to the SCADA by RS232. Then you will use the Sysmac driver. Have you installed & configured it ? Are there any instructions in the SCADA or driver help ? Typically the RS232 connection will use the same cable configuration as your programming cable. Quote
gorichan Posted January 16, 2007 Report Posted January 16, 2007 Sysmac driver? Hmm. I dont think that I have installed or configured it. Where to get one? What is the name of OMRON OPC Server? Is there any specific one? Im still new with OMRON PLC. During my Internship attachment I managed to link between the SCADA package(Adroit) with RTU(SSE RTU). Now, for my Final Year Project, I want to link Adroit with OMRON PLC. Quote
PdL Posted January 16, 2007 Author Report Posted January 16, 2007 Are you going to connect the SCADA PC directly to the PLC by RS232 ? In that case I think you won't need to use an OPC server to connect. Omron's OPC server is called CX-Server OPC, but most common OPC servers like Kepware support all Omron protocols. Quote
gorichan Posted January 17, 2007 Report Posted January 17, 2007 This is want I want to do. I have one PC (which is installed with CX-Programmer,CX-Server and Adroit SCADA) and one OMRON PLC (CQM1H CPU41). Those PC and PLC are simply connected together by RS232. I want all the events occur at CX-Programmer to be sent to Adroit SCADA so that I can manipulate the data from CX-Programmer and represent them graphically in Adroit in the same PC. Are you going to connect the SCADA PC directly to the PLC by RS232 ? In that case I think you won't need to use an OPC server to connect. How can I connect the Adroit with CX-Programmer or PLC without using CX-Server? Quote
scottmurphy Posted January 17, 2007 Report Posted January 17, 2007 It sounds like you are confused slightly, you actually want to 'manipulate' the data in the PLC, and represent this on the SCADA ( Adroit ). Quote
gorichan Posted January 17, 2007 Report Posted January 17, 2007 Can you please help me on how to configure the CX-Programmer and CX-Server in order the events can be delivered to Adroit SCADA? Any useful links maybe. TQ Quote
PdL Posted January 17, 2007 Author Report Posted January 17, 2007 CX-Programmer and CX-Server on itsself are NOT suitable to use as middleware for a SCADA system. For this one could use CX-Server OPC or any other OPC server that supports Omron. But please try to understand, an OPC server ONLY acts as a gateway between your SCADA and the hardware, you cannot manipulate the PLC program with it! Quote
gorichan Posted January 17, 2007 Report Posted January 17, 2007 You mean, CX-Server and CX-Server OPC are not the same software? I understand greatly that OPC cant be used to manipulate the PLC. It acts as the protocol translator between PLC/RTU and SCADA. To manipulate OMRON PLC, CX-Programmer will do the job. Quote
PdL Posted January 17, 2007 Author Report Posted January 17, 2007 You keep talking about OPC. Why can't you use Adroits Omron driver ? Quote
gorichan Posted January 18, 2007 Report Posted January 18, 2007 ok ok. my mistake. Now I know that Adroit can talk with Omron just using Adroit driver. Ignore OPC! But, how to configure the communication setting inside omron? I read the CX-Programmer manual that the file must be converted into .CDM type file. It also says that 'For each symbol required to be shared, set its Link the definition to the CX-Server file setting'. Im still trying to figure it out. Any helpful and additional reference/ manual that I can refer to? Thanks. Quote
PdL Posted January 18, 2007 Author Report Posted January 18, 2007 See if you can find any documentation from Adroit about the Omron driver. Post any screencopys of the Adroit driver configuration. Quote
gorichan Posted January 18, 2007 Report Posted January 18, 2007 Haha. I dont know why I think so complicated. Too much of reading manual I quess. I got mess up. Plus, Im still new with Omron. Ok, Ill try it out tomorrow. The PLC is at the laboratory. Gotta go now. Wanna have my dinner. Tata~ Nway, thanks for your help. Quote
