  1. Allen Bradley 1794-ADN

    Hi Money4nothing Unfortunately I have tried this one a few times already with no luck. At the moment on the network I'm currently trying it on I have 3 ADN's and one 1770-KFD connected.RSnetworx can see the other ADN's (Nodes 2 & 3) no problems but the ADN at node 4 can not be seen.I manually entered the Node 4 ADN into the table on RSnetworx so I could try and get the Class instance editor up for it but each time I try the class instance editor comes up with the following error. ("Error opening connection to this device. Error code = 0x80070057. Online operations will not be possible for this device. Please make sure that the device is connected to the network and try again.") One thing I noticed was that the only light up on the offending ADN is the power light all other lights are off. This is the same if connected to the network or not. Though when you first power up the device all lights seem to go through a normal start-up sequence. I can also confirm that the network cabling is fine as other devices work off the same cable that is plugged in to the offending ADN. The module seems to have had its config scrambled and is no longer allowing comms to or from it. Is there a hardware way of resetting it or is it a back to factory to get it restored? Is there any way possible that I can could possibly do it? Thanks everyone.

    Hi Biker. I also have a 1770-KFD which I have tried hooking it upto with no luck. It causes the old Network status light to start flashing red. The hardware address for the ADN's are set via thumbwheels on the front. Thanks.

    Hi. At this point I have disconnected all Flex IO from teh adaptor and then connect it into a working network (via a drop cable that is already on the network) which then causes the network to fail. I assume that the ADN maybe spitting out Bad data. Though I'm sure it is only doing it because something got scrambled during the last config change which it was working perfectly before hand. Thanks.

    Hi thanks for the info. But the only problem is I cant see it on the network as it causes the network to fail as soon as it is turned on. Is there a way of clearing the flash memory to factory via the hardware some how? Thanks.
  5. I have a 1794-ADN module that no longer wants to play the game. I tried to download a new configuration to it while it was still in the scanners scan table and ever since that as soon as I power up the ADN on the network it causes a "bus off" condition. Does anyone know of a way to reset this module to factory to try and get it to go again? Thanks. Joe Maher.
  6. Hi Guys. Thankyou very much for your replies. TechJunki, I used your example and it worked the way I wanted it to. Thankyou very much it now saves much time doing search and replace's. Regards Joe Maher.
  7. Hello All. I'm tring to subsutute a value in a DDE link to a rslinx topic to a value within a cell of excel so I can make this excel control panel up to be used on any piece of equipment that I need to control at the time. This is what I'm tring to do. This is the DDE link: =RSLINX|Area_2_PLC_1!'LHVA_3154TF_C.Auto_Mode,L1,C1' I'm tring to replace the topic "Area_2_PLC_1" with a value in Cell A1 and i'm tring to replace "LHVA_3154TF" with a value in cell A2. Can this be done? Thanks Joe Maher.
