Is the Panelview input going directly to N13 or is Panelview tag actually a ST (string) type that is being moved to N13 in your PLC program If it is ST type, use the ASR instruction to compare to a known value and add logic required after that asr.bmp

Where there are question marks, there are probably errors with the tag or the math you are doing. Where there are hashes, the numeric display is probably too small. Try allowing more digits or allowing decimal places

I usually have a delay before starting the DeviceNet Scanner. Gives time for things to power up/settle down Try: TON Timer ? ? BST XIO Timer.DN OTE Local:3:O.CommandRegister.Reset NXB XIC Timer.DN OTE Local:3:O.CommandRegister.Run BND 5 seconds in the preset should be more than enough

Why is the Robot the master? I have used this setup (1769-SDN and IRC-5) on multiple installations and the PLC was always the master and the robot was a slave like a normal DeviceNet node. I use input size 20 and output size 20 on the PLC and map various bits and words to the UDI and UDO table in the IRC5 Can you post youe .DNT file from RSNetworxs, might be able to shed some light for you

You can still reset the drive over comms. You write 2 x words to the drive, 1st word is control word and the 3rd Bit in the control word is reset. 2nd word you write to the drive is reference. Check out page 95 of the User manual. Not sure what page in the PowerFlex 40 manual, but the control word is the same. Edit: Too slow again PowerFlex4.pdf

Have you used a scope on the "encoder" to confirm operation. I know you said the electricians have checked the "magnetic pickup speed" but if it is conected to a HSC the pulses will be very fast. I have been to a lot of call outs to "fix" faulty PLC's/High speed counters only to find the problems are with the encoders or encoder wiring

Post the RSLogix 500 code from your old system and members could see how it was done and come up with a similar solution to what your used to

I thought you said the machine builder went out of business? .APA is the file you need. It is a compressed version of the project containing all info you need

You can upload the .MER to a compact flash card or a USB drive from the Panelview if you can get to the configuration screen. Then post the .MER to this forum and someone could have a dig around for that password. If there is no "go to configuration mode" button, cycle power to screen and when it powers back up, press the small white square in the bottom left corner. This should take you to configure mode. Navigate to file managment and copy file from internal storage to external storage (your compact flash card or USB drive). Might help to post your .ACD file aswell, might be some clues lurking in there.

I will try the explicit MSG to read D308 in my application. My application does not need a really fast update, so should be OK for me. If I find a way to improve update time, I will post it here

Are you trying to read D308 and D309 (Units travelled) or are you trying to read actual pulses from Encoder? I didn't think you could get an actual position from The PowerFlex40P. I am interested how you are reading position, because I would like to utilize this for my current application. I have 22-COMM-E connection to my drive

If you have an L32E, use ethernet connection from your lap top. If it is a direct conection use a cross over cable, otherwise patch the PLC and your laptop to an ethernet switch. Set the IP adress in the PLC using BootP, set your laptop IP to something in the same IP range, then use the ethernet IP driver in RsLinx.

Didn't even think of the Net-Eni. What a good Idea. This would save on a lot of hassles and could get the 5/03 on our engineering ethernet network for programming/troubleshooting as you mentioned. The DB/9 comm port is currently unused, so this wont be a problem. Thankyou for your suggestions

Currently I have a PV+ 700 (2711P-B7C4D1) connected via ethernet to a CompactLogix L32E and a Panelview Classic 600 (not sure on part number as it is hard to get to the back of it, but it uses DH485 comms) connected via DH485 to a SLC5/03. Looking at upgrading the panelview classic to a PV+ 700 (2711P-B7C4D1) as some of the buttons have failed and it would reduce the amount of spares I would need to carry, but would like to add some extra features at the same time. The 2 machines/PLC's are close to each other and 1 operator controls both. I was hopping to integrate the 2 Panelview projects together and give the operator control of both machines from either panel. I hope this will also enable me to have the same project loaded in both panelviews. I have done panelview projects previously with 2 differnet PLC's connected, but they were both on ethernet. I understand the potential problems with having the 2 screens trying to write to the same tags in the PLC and will deal with this appropriately. My real question is about the comms setup. I have not had a lot to do with DH485, but understand ethernet fairly well. I will connect both Panelview's ethernet ports to the same 5 port switch as the CompactLogix so they will be able to access tags from that. I was going to configure the PV+ serial ports for DH485 (can you do this?) and connect 1 to the RJ45 (DH485)port on the SLC5/03 and 1 to the serial port on the SLC5/03 and convert that port to DH485 (can you do this?) Hopefully someone has some advice, answers to my questions or past experiences with Panelview + to DH485 Thanks in advance

How did you get on with the SEW ES1T Encoder? I am about to do a basic positioning project with a Powerflex 40P and SEW Motor Gbox and need to purchase the SEW equipment soon. If this did not work for you, I will purchase the AB encoder instead
