Sullair eConnect/PanelView Notes
Application note for A-B PAnelView 600 Plus to communicate with Sullair eConnect using Modbus protocol.
PanelView Info
1. Install FT View ME Studio on PC.
2. Install KEP Server Enterprise on PC (all drivers).
3. PanelView Settings:
a. 192.168.2.10
b. 320 x 240 screen size
4. Need to flash PV firmware: c:\Program Files\Rockwell Software\RSView Enterprise\FUPs. Make sure “Ethernet” is selected on Kepware drivers.
5. When upgrading firmware, got “not enough memory” message. Had to change PV startup configuration to “go to configuration screen” instead of “loading and running application”.
6. Apparently, the Kepware configuration is the only thing that affects the PanelView communications setup – not the RSLinx Enterprise settings as normally. After any changes to Kepware, the application must be recompiled.
Sullair Info
1. Econnect design company: ICC Designs, 608-831-1255
2. Econnect card had different IP settings than shown in the book. Used hyperterminal to change them to match the book.
3. Hyperterminal settings for connection: 38400 / 8 / none / 1 / hardware
4. IP address settings for Econnect: 192.168.1.2 / 255.255.255.0
5. Before Sullair system was configured using the HMI, Panel View diagnostics returned an exception 7 (neagative acknowledgement) indicating that the Etherent communications were OK, but that the eConnect was not communicating to the Sullair control system through the RS485 link. The PanelView displayed all “***” in the data fields.
6. Sullair HMI configuration:
a. Factory Setup -> Comm Module -> Yes <Enter>
b. Sequencing -> Sequence By Remote
7. Only one compressor is connected on this application, but multiple compressors could be connected. On multiple setups, Com1 uses addresses 1 through 200, Com2 uses addresses 201 thru 400, etc.
8. Addresses for analog holding registers are offsets. For example parameter 105 is Modbus address 40105 (this shows us as 400105 in the Kepware server).
9. Wired start relay to output 4 (Modbus address 43125 (403215 in the Kepware server). This is dout4, terminal J9/5. Output On =Run (External relay is de-energized). Output Off =Stop (External relay is energized).
10. Remote on Sullair Supervisor must be illuminated (Red) for PanelView remote start/stop button to work.

Outgoing Email Problems While Travelling
If your incoming email works OK, but you can't get your email to send, try changing your outgoing SMTP port from the default of 25 to 465 or 587.

Make RSLinx run as an Application (On Demand)
Start -> Programs -> Rockwell Software -> RSLinx -> RSLinx Classic Launch Control Panel.
Stop the RSLinx Service and uncheck the "Always Run As Service" box.
This will allow RSLinx Classic to run as an Application, not a Service, and only when required by RSLogix or an OPC/DDE client, or when you manually open it.
If you use the 1747-PIC driver regularly, you're going to have to get used to the Launch Control Panel because that only runs in Service Mode.

How to Creat a Bootable Ubuntu Flash Drive
Here are the steps to follow to create a bootable ubuntu 9.10 (this version is also called Karmic Koala) flash drive (minimum 2GB). Their version numbering system is pretty weird: version 9.10 means it was finalized in the 10th month of 09!! And the Karmic Koala just designates version K, but they started at the end of the alphabet instead of the first.
(1) Download the CD image (.iso file) from www.ubuntu.com:
(2) (Optional, but recommended) Verify that you got a good download by running md5sum found at http://www.nullriver.com/products/winmd5sum on the downloaded file and comparing to the hashes found at https://help.ubuntu.com/community/UbuntuHashes. For complete instructions on this process, go to: https://help.ubuntu.com/community/HowToMD5SUM .
(3) Create a bootable flash drive following the instructions found at http://www.pendrivelinux.com/create-a-ubuntu-9-10-live-usb-in-windows
(4) Restart your PC and set the BIOS boot order to the flash drive(this may be a subset under the hardrive or CD), save the BIOS changes and reboot. Somewhere along this step you will have the opportunity to specify the size of the ‘casper-rw’ file you want to set up on the flash drive. I set mine to 2GB, I think, but you can resize it later by following the directions at http://www.pendrivelinux.com/how-to-resize-casper-rw-images (from windows) or http://www.pendrivelinux.com/how-to-create-a-larger-casper-rw-loop-file from linux.
