You are probably not going to find very many ActiveX controls that act as an embedded driver for talking to devices. Your best bet is to lookf for an OPC toolkit for .Net and use and OPC Server. Kepware Technoliges has an OPC ToolKit called ClientAce which you can download and try out. They also have several Omron drives for the KepserverEX OPC Server that are provided in a single driver suite. Go to Http://www.kepware.com to download both.

Hi, I did all the testing and documentation for that and helped several customers impliment it. the FX2nC-Enet-ADP module actually works much better than the original module that was released in Europe. It allows 2 connections so that you can do data collection and connect the programming sofware at the same time. If you follow the instructions in the Kepware Mitsubishe FX driver help file you should not have any problems. If you do then contact technical.support@Kepware.com. It is a free service and if they can halp. Fred Loveless Senior Applicaiton Engineer Kepware Technologies

You need to set up a watchdog so that you can re-initialize the adapter on communicaiton loss. The primary issue is that the ethernet adapter does not allow multiple connectiosn and when you unstable etherent connection causes an abnormal loass of the TCP Socket connection the PLC does not know to release on its end. When you restart the devices this causes the listen port to be re-initialized. Fred Loveless Senior Application Engineer Kepware Technologies

If you want to isolate them and limite the possobility of cable damage you could use wireless serial to ethernet converters. There are several manufacturers that have Wireless converter solutions. You will need some clear airspace to avoid signal block and bounce but that is really the only drawback with wireless these days.

The description of this error is "The item is no longer available in the server address space." it is being returend by RSLinx. Typically this is seen when a items fail to be added but the client application do not remove it from the OPC Group. Can also indicate that the server has timed out and removed all the items from its poll table. RSLinx may be posting a corresponding error.

If you have any question about KepserverEX you can contact our support center for free via e-mail. (technical.Support@kepware.com). We also have many examples and white papers on line that you can download. i do advise looking at our VB example code which will show you how to do OPC connections to the server.

I ran the support department for several years at Kepware and I do not recall ever getting a complaint about any of the new processors. Automaton direct private lables our KEPServerEX as KepDirect server. Fred Loveless Sienor Application Engineer Kepware Technologies

I am pretty sure it so the vertical rung connectors from rungs with outputs. I seem to remember taht you cannot do that. You can still use that same logic on one rung wihtoutthe output coils y002 and y003 and then have t rungs by them selves for settng those coils.

This is pretty vague. Can you at least tell us what PLC model and ladder software you are using. Fred Loveless Senior Application Engineer Kepware Technologies http://www.kepware.com

Depedning upon the SCADA/HMI package that you are using you may already have access to the Kepware server and drivers as many of the major manufacturers OEM the software for distibution with thier packages. Go to Kepware's web site http://www.kepware.com for a list of the manufacuters they work with.

The FINS Protocol requires the server to use the same port for bindback by both ethernet cards. And yes the driver supoorts both cards. You might want to try multi-homing you PC's network card and use the new IP for the second card. This allows for simultaneous communications to both ETN cards and bind back to seperte IP's. There are other ways to improve your communicaitons as well. If you contact Kepwares Technical support technical.support@kepware.com support is free.

I maybe mistaken but I do not believe there is a communicaitons path between the 2 controllser so you are going to have to use a server to read data from each device and then use a bridging software to move the data back and forth. As luck would have it Kepware has driver for the compact logix and a driver for the FX PLC's The last piece you will need is the LinkMaster product which is an OPC bridging software. You can download full functioning demos of the server with all of the drivers and the LinkMaster from the Kepware Website (http://www.kepware.com).

The best way that I know to do this is use wire shark and filter for all commmunicaitons going to and from that PLC's IP address. You will then be able to see which IP's are hitting it. Fred Loveless Support Manager Kepware Technologies http://www.kepware.com

If you have an OPc server that is already talking to the PLC5 you can use Kepware's LinkMaster to read data from the PLC5's server and write it to the Delta V Server. We have customers doing that all the time. If the Delata V does not have the OPC Server implimented but does have the Modbus Ethernet or serial Master implimented then you can use the KEPServerEX Modubs drivers in Slave mode and using LinkMAster pull the data from the PLC5 server into the Modbus Slave image and then Delta V can poll the slave to get the data. This is done quite requently as well. You can download a full funtioning demo of the products at http://www.kepware.com If you have any further questions on how to do this you can contact Kepware Technical Support (Technical.support@kepware.com) or call us at 888-537-9273 x211.

The Micrologix 1100 uses CIP so you will need to use a driver that supports it. Kepwares ContolLogix Ethernet driver has support for the ML 1100. http://www.kepware.com Fred Loveless Support Manager Kepware Technologies

Depending upon the number of items you are reading a poll rate of 2 seconds shoult not impact your processing. The PLC will have to handle request from seperate connections which will slow the procees a little bit. Much like trying to hold 2 seperate conversations will slow your response to any one person. KepserverEX optimizes as much as possible to minimize communications to the PLC. The driver will block the requets to get as much data as possible with the fewest number of requests to the device. The other key to optimizing the performance in KepserverEX is to place each device on its own channel whcih allows the server to talk simultaniously to all devices. Please feel free to contact Kepware Technical support if you have any additional questions. We are there to help you. Fred Loveless Support Manager Kepware Technologies

Depending upon the device you are using Kepwares OPC server may be able to talk to it and you could then use the Kepware DataLogger to log data to MySQL. Fred Loveless Support Manager Kepware Technologies

Modus connectivity in the Panel views is accomplished using KepserverEnterprise. The latest Enterprise builed ditributed by Rockwell contains support for Modbus RTU Serial Master and Slave, Modbus Ethernet Master and Slave and Modbus Plus as master and slave via a Hilscher Modbus Plus card. KepserverEnterprise and updates can only be acquired from Rockwell.

Hi, yes this is the programminggable and you can do peer communications to the FX48 using Kepware's Mitsubishe FX driver. ASPIC will have no problem connecting to the server. Fred Loveless Support Manager Kepware Technologies

With a SQL data base you could use an ODBC interface to see the data. Check out Kepware's ODBC Client Drviver (http://www.kepware.com/Spec_Sheets/ODBC_Client_Driver.html) RSViewSE can connect to it with no problem.

Keeping in mind that OPC is the data transfer layer between the OPC Server and OPC Client no communications server should cause the PLC to crash. Who makes the OPC server that you are using.
