How do I reset my processor back to factory defaults?
FAQ ID: 131
Why can I not get any Control Output from my PID loop?
Most likely you haven't entered a high limit for your Control Output in the PID setup. The default is 0 and the maximum is 4095 binary. Your must enter something in this field (Word+31) from the PID setup or from ladder. You should also check your Control Output word (Word+5) to see if you are actually getting Control Output. If this value is changing then make sure you are writing this value to the physical output device. This will most likely be an analog card or Time-Proportioning ladder for a discrete output point.
FAQ ID: 132
Why does my Setpoint Value change in my PID loop when I go from Manual to Auto from the PID view or ladder?
You are probably in Bumpless Transfer Mode 1. In this mode, the Setpoint Value is forced to the Process Value on a manual to auto transition. You should be using Bumpless Transfer Mode 2 if you do not want this to occur. This is covered in the Bumpless Transfer section of the PID chapter in your User Manual.

FAQ ID: 1308
How do I use a variable as a timer preset?
In your timer box where you are currently typing 'Kxxx' for the preset you would put a V memory address such as V2000. Make sure that this address is only used for this purpose. Now open a data view and type in V2000. You would use this same V memory address for every timer that you want to have the same value.
Click the yellow E button with the red circle and slash in the upper left of the data view window to enable edits. Now you should have a column titled edits on the right of the V2000 you typed in. Enter your value in this column next to V2000 and press the middle of the three buttons at the top right of the data view.
Please note that you can use other V memory addresses than V2000. The full list of available addresses is available in the PLC -> Memory map menu item. Also you can find the list of available memory in Chapter 3 (or 4 depending on the PLC model) of the User manual.
FAQ ID: 1340
I plan on replacing a D4-440 with a D4-450, Does the note on the D4-450 in the web store regarding F4 speciality modules apply to me?
If your system contains F4 intelligent modules with a date code of 0996 (September 1996) or earlier they would have to be updated to work correctly with the 450 CPU. This update would be considered an out of warranty repair of the F4 modules and would have to be performed by FACTS Engineering (www.facts-eng.com / select RMA Request).
It would be better to replace a 440 with another 440, or replace the affected F4 intelligent modules in addition to replacing the 440 with the 450.
If your F4 intelligent modules are newer that 0996 (September 1996) then they should work as expected with the 450 CPU.

"I can't see my ECOM(100) with NetEdit. What do I do?"
If NetEdit3 doesn't see the ECOM module when you press "Scan Network", check the following:
1) Verify Link Good LEDs are illuminated on module and connecting devices like hubs or unmanaged switches.
2) Turn OFF any WiFi devices or other ethernet devices.
3) Firewalls need to be turned OFF for initial connection (see Windows Help). Also, turn OFF any antivirus or other protection software that can interfere with ethernet communication.
4) Try to PING the ECOM module to establish basic connection (see Windows Help, or search for resources on internet if not familiar with these steps).
5) You may need to disable any other network adapters besides the one physically connected to the ECOM or network the ECOM is on. If you get "Transport Protocol error", try the instructions in this link:
Go to Step 4, Item C. The latest version of NetEdit has the ability to select the specific network adapter, by going to the main Menu, select "Network", then "Adapter" and specifying which installed adapter you want to use ( it also lists the IP addresses of the adapters). We strongly suggest you download the latest version of NetEdit here:
6) If you have a network administrator, you may need to check with them to verify the configuration of the local network.
7) If you have Windows XP or earlier, and you still can't make a connection, you should consider trying the IPX protocol. Click the IPX button in NetEdit3. If you get the 10047 error, you need to install the NWLink/IPX protocol to your computer ethernet card.
See Windows Help for this procedure, or try this link
If you can't connect to an existing/unknown ECOM100 in a network, and the card is likely newer than 2007, by powering-down and putting dipswitch 6 ON, then powering up, the IP address will be reset to all 0's, and should become visible to NetEdit3. You must power down and turn this dip back OFF for card to be able to operate properly.
