Hi there, I’m not sure how familiar most of you are with Wago remote I/O, but I hope you may have some solution for the following connection problem I’m having. I’m working on a project to modernise an old folder collecting machine for which I’m using an Omron CJ2M Cpu33 together with 8 Wago 750-352 remote I/O units over ethernet/ip. These Wago units all contain two 8DI digital input cards and two 8DO digital output cards alongside a 750-610 bus power supply card. Adding them to my network in CX network manager is no problem and all seems to work fine. That is, as long as I don’t physically add the bus power supply card, which I need to, well.. power the Wago bus. Soon as I add this card (which was in place while making all the necessary settings to the Wago and Omron units) it just won’t connect. Remove it and it connects like it should. As far as I know the power supply card has no I/O addresses or other communication functions whatsoever, so I can’t get my head around it. Even stranger is that when instead of it I add an analog input card, with bus power connections build in, it connects without a problem. The .eds file only contains info about the main Wago unit, after installing it I should be able to add any kind of I/O card and address them in the Omron software. Also, the supply card is added and visible as a fifth card in the Wago I/O settings and the I/O status led is green during this error. Therefore I would say the problem is at the Omron side. Any sugestions? Thanks in advance Andy - The Netherlands
Hi Guys, Did anyone performed the process value simulation of Rosemount 5300 Level Transmitter (FF Communication) using Emerson 475 communicator? The simulation jumper is not available physically on the device. The only simulation option in the hand held communicator available in the following path. Configure>>Manual Setup>>Classic View>>Advanced Transducer Block>>Parameters1.. But that option too is highlighted and not editable. Can anybody help me how to simulate the value from device so that I can check in my host DCS (Siemens PCS7). Thanks in Advance, GJ
Hello everyone, I am working on foundation fieldbus protocol with PCS7. I am facing problem of voltage drop in successive AFDiS (Active Field Distributor). As part of the DCS hardware I am using CP443-5 EXT.-->FF Link (Redundant)-->FDC157-->AFDiS1-->AFDis2-->AFDiS3. The architecture is daisy chain not the loop. I have checked the current consumption using fieldbus calculator. But everything is fine as per calculation. Even I had tried connecting the AFDiS one by one and also with no load condition. I didn't find solution to this problem. I am attaching hereby the sheet of values which I obtained after connecting trunk and spur stepwise and measure voltage at each point. However when I am using AFD in combination with AFD, the amount of voltage drop is not that much significant. Please advise a possible solution. Thanks in Advance, Gaurav J
Hello Everyone, In PCS7 hardware configuration, I have connected IM153-2 FF link to a profibus master connected with CP443-5 Ext. And afterwards I have connected the field instrument with FF communication with the slave bus on FF link. However I am not able to delete the equipment once connected. The error is showing as the object is locked. How to unlock and delete the objects which were takes for testing purpose. Thanks in Advance, GJ
