Any third party controller which is CIP based or can communicate over Ethernet/IP. For example, OMRON has come up with a special Ethernet/IP Interface to communicate with Logix controllers, now if I want to connect PVP directly to OMRON over Ethernet/IP. How can I communicate? According to my understanding there are two ways of doing that i) through Kepserver ii) by some setting/configuration in RSLinx Enterprise. And as of now in Kepserver no such driver has been developed(I may be wrong) and about RSLinx Enterprise i have no idea. If anybody has done similar thing or facing similar problem......please share your knowledge!! Thanks and Regards Rohit

Hi, Anybody here having any idea about how to communicate PanelView Plus to some other PLC/Device (non-AB) over Ethernet/IP. Even small clues will help...... Please suggest!! Thanks and Regards Rohit

Thanks Rammin for replying..... I got the answer to my question while browsing and downloading some manuals from GE Support Website. There is no such manual about 90-30 Hot backup system.... but they have on online help file, which gives a fair idea about the system..... In that help file the Failovertime is described as: Failover Time: There are two considerations for failover time. 1. Token Rotation Time: This time interval varies somewhat from one bus to another…. it depends upon the update period for the I/O LAN. Also, it is a function of the number of devices on the LAN, the quantity of input/output data associated with each device, the LAN's baudrate, and the quantity of global data being transferred. Generally the time period ranges from a few milliseconds to perhaps 100 milliseconds. 2. Mastership Time: This is the time interval for the Backup PLC to recognize that the Master PLC has failed. It takes one or two PLC scans to determine that the Master has failed. Then it takes an additional scan to activate the output data stream in the Backup PLC. Lacking output data from the current Master's GBC, each output circuit on each device on the I/O LANs will hold its last state for up to three Token Rotation Times before it assumes the Default State unless there is output data from the Backup GBC. Then the output device will begin using output data from the other GBC. The actual failover time is the longer of either…. 3 Token Rotation Times, or 1 Mastership Time. I am attaching the On line Help File also...... Thanks Rohit Singhal MAXON.zip

Hi All, Can anybody here tell me about the switch over time between two CPU's in a GE 90-30 Hot Backup System. What is the exact relationship of this with the Update time of the Genius Bus? According to my knowledge the Switch Over Time = 3 times the Genius Bus Update time. Can anybody validate this? Is the Switch Over between the CPU's is really bumpless? And without using any extra hardware how they implement a Hot Backup system? Any manuals supporting this will be great...... thanks

Thanks for Replying....... Yesterday i was trying to communicate with the QJ71E71 Ethernet Module via FTP from the PC. But i was not able to do that with Internet Explorer.... Then i tried the same with the DOS and i was able to communicate and go inside the Module, there are some dedicated FTP commands which i have to learn now. Also Reading and writing function is also available but i m still trying to do that.... I am attaching the Manual which describes different ways to communicate with the Ethernet Module... If somwbody has done the similar work ... please help!!! Thanks Rohit Singhal Ethernet_Module_UM_Application.pdf

Hello, I want to communicate Allen Bradley Control Logix PLC with Mitsubishi Q-Series on Ethernet. I am well conversant with AB Products but very new to Mitsubishi. I have already configured the Mitsubishi PLC and able to upload/download from PC via Ethernet and the system is working fine. I am using Q02H CPU and QJ1E71 Ethernet Module. Has anybody did any third party comm. with Allenbradley over Ethernet... even small clues can help... Please ask for any more inputs needed?? Regards Rohit Singhal

thanks pdl ... but does that mean that all the parameters in the vfd ar any other device connected to devicenet master will be automatically dowloaded to the slave... if we replace the exact match of the faulty device with same node number.. please suggest

Hi Everybody, I am looking for some functionalities in devicenet specially for Omron Master/Slaves...... Can Anybody guide me that whether we can make online replacement for Omron Devicent Slaves Online without disturbing the Network and Process without any configurator.... To be more precise if we say i have an VFD over devicenet connected to a Devicenet Master DRM21 and it gets faulted, now i want to repalce it online without any configurator by just setting the same node number... is it possible ..please advice.. I am very sure about Allen Bradley, it is having ADR facility in them using which i can do the same thing very easily...... Please suggest Rahul
