I have a Base tag of BOOL logic that will not activate the MOV output. The Base tag is paralleled with an Alias tag for a NO pushbutton. When the pushbutton is actuated it produces the desired output. Has anyone encountered this issue from a togglebit base tag before? Why would a base tag produce a different outcome from that of an alias tag that function properly?
I have a data logging process on a CJ1M CPU13 via RXDU command on port 2 of SCU41-V1 It has been working, but has stopped. There are 2 identical machines. Both Honeywell bar code readers work on 1 machine, while the "RD2" led stays lit on one machine, and wont complete the RXDU command. On the working machine, it simply flashes quickly during data receive. I have compared the program in both, and it is identical. Cabling from both machines have been tested - works on one, not on the other. Even swapped out SCU41-V1 with same results, so I am pretty certain it is a setting in the main processor of the non-working unit. I did a compare of SCU settings and they are identical. #0 is moved into C #2213 is moved into C +1 on first cycle. Unit number is 3 1594.06 never seems to complete, which is an open contact in series with A202.02 (N.O.) to trigger RXDU (255) A202.02 is value 1 1594.06 stays at 0 when I trigger 1594.06 via laptop, it sends garbage data once. Any ideas?
Hi guys, I recently was asked to configure a computer to host an Factory Talk SE Client application. I was able to get everything working except the trends and the Alarm window, all I have is the cross hatch screen. at the bottom of the screen it is saying cause: Trend: CAB file missing on the server: http://hmi1/RsviewActiveXControlSetup/RSTXView2ocx.CAB. I have worked on this for a while and am stumped. All the other computers on the same domain network are working fine, so it leads me to believe my problem is with my installation on the new computer. Any suggestions or if you need more input please let me know. Thanks
I am very new to PLC's, I work in a power plant and we have an ABB DCS. We have some vendors that use PLC's and they try to make them work with our system. Currently I am working on a project were I am trying to add 8 analog outputs to the PLC. I am working with two 1756-L71 controllers (redundant) and the rev for the program that was written 20.01. Basically I have 8 analog inputs that I want to bring to the spare analog outputs that I have. I want to see these inputs in our DCS. I wrote simple logic that at the end of the rung has a move block moving the source which is the input and taking it to the destination which I made an alias tag for the output channel that would correspond. Problem is I can see the source number moving, but the destination number stays at 0. I can type a number into the destination and it will work. I can see my 4-20 signal I am sending out in the DCS. Everything before the move function is true, I have and open contact, and a closed contact and they both are green. This is happening on all eight of my outputs that I am working on. Please help I have learned a lot from this experience but I cannot figure out what has me stuck this time.
