Problem: C-more Help File opens but there is no help, just the "Contents".
Cause: Windows Security Update: It seems there is something new in the Windows Security "features".
Solution: To get the C-more software to work, check if the EA-HELP-chm file is in the C-more installation folder:
C:program files (x86)automationdirectcmore_ea9
If the file is there, check to see if the properties show an Unblock button. If so, unblock it.
If the EA-HELP.chm is not in the folder, it means the software was not unzipped before installed (if downloaded from the website) or it was installed from a CD with anti-virus software running.
In this case, you will need to unzip the downloaded file and then run the installation again.

Why is it that only 7 digits can be entered in the "Numeric Entry Object "when using Floating point numbers as the data format?
32-bit Floating point (single precision floating point) only has a decimal precision of 7 significant digits.
The significand of the 32 bit Floating point format is only 24 bits.
Which seems to like it should be 8-digits, but you can not get up to 99999999, you can only get to 16777215.
That is why it is about 7 decimals. It's overall max precision is 3.403 x 1038, but that is represented exponentially.
64-bit (or Double Precision) Floating point has a decimal precision of 16 significant digits

FAQ ID: 1297
My C-more is not displaying the same floating point number as my (PLC, Spreadsheet, or other platform). Why is this?
This is usually due to truncation or rounding of the floating point value due to the number of decimal places that are displayed.
All of our products follow IEEE-754 floating point specification.
The following example uses this IEEE-754 calculator to show how rounding can affect floating point numbers.
Enter 13.609 and choose the “not rounded” calculation, notice that it generates a hexadecimal value of 0x4159BE76.
Switch to "convert Hexadecimal value to decimal value" (at the bottom of the page) and enter in 0x4159BE76, you will get a result of 13.608999252319336.
Enter 13.609 again and choose the “rounded” calculation, notice that it generates a hexadecimal value of 0x4159BE77.
Now switch to "convert Hex value to decimal" and enter in 0x4159BE77. You will get a result of 13.609000205993652.
This shows that 13.609 is not a pure number but has been either truncated or rounded since the binary pattern of 0x4159BE77 is being used.

FAQ ID: 1311
Can a 90/30 CPU (IC693CPU311) be used with a C-more or C-more Micro Panel ?
It depends on the firmware in the CPU 311.
CPU 311 firmware before 4.40 did not support SNP-X.
SNP (Series Ninety Protocol) is not the same as SNP-X (Series Ninety Protocol Express) and will not work with the C-more

Once you open the file, go to the [App] section of the file and add this at the bottom:
PING 1 enables. 0 disables PING
PINGTIMEOUT= is in milliSeconds
PanelTimeout= is in Seconds
You need to re-start the software anytime you change the values above.
FAQ ID: 1329
Can I use a Compact Flash (CF) card to transfer a project from a Cmore panel, edit the project, save it to the CF card, and load the project back into the panel from the CF card?
Yes. The procedure works almost like using a USB pen drive with a few differences. Here are the steps:
1. Turn on the panel without the CF in the CF1 slot.
2. Verify that the project loads on the panel.
3. Insert the CF card in the CF1 slot.
4. Go to the SYSTEM screen, select: MEMORY, BACKUP, CF1, NEXT, select PROJECT and also SYSTEM (you can select others as desired), NEXT, then OK.
5. The backup should complete. Press OK.
6. Exit the SETUP screens and remove the CF card.
7. Place the CF card in the reader in your PC.
8. Open the Cmore programming software.
9. Select File/Open Project.
10. Point to the CF drive and change 'Files of Type' to be STARTUP STORAGE (*.EAS).
11. Go to the EA_MemoryCopy folder and select the StartupStorage.eas file and click Open.
12. Make your project edits.
13. Select File/Project Transfer. On the Step 3 window, select External Memory Device instead of Panel. In the box labeled "Select a Drive:", select the drive letter of your CF card. Click the 'Transfer' button. On the Select Firmware file window, make sure it's using the latest firmware file, then select OK. If a window pops up saying that x:EA_MemoryCopyStartupStorage.eas already exists, click YES, you want to replace it.
14. Remove the CF card from your PC reader.
15. With the Cmore panel already powered up, insert the CF card in the CF1 slot.
16. Go to the SYSTEM screen, select: MEMORY, RESTORE, CF1, NEXT, select PROJECT and also SYSTEM (you can select others as desired), NEXT, then OK.
17. After the restore is complete, the panel will reboot. Because the CF card is still in the CF1 slot, the panel will try and boot from the CF card. To view the new project you restored, you will need to remove the CF card from the CF1 slot and power cycle the panel.

FAQ ID: 1373
How can I see my C-more's public IP address? I have a dynamic public IP address and it changes.
If you have the ability to send E-Mail from your C-more, you could have the panel send you an E-Mail on power up or based on an event and examine the E-Mail header for the public IP of the router the C-more uses.
The sending IP address information will be embedded in the E-Mail header.
In Outlook 2007 you can view the header information by highlighting the E-Mail, right clicking and select Message Options.
My system sent me an E-Mail on power up and in the header it says

Can you update a project and optionally the firmware using a compact flash card in the built-in CF1 slot of the compact flash capable C-more panels (non -R versions)?
Yes, you can successfully update a panel project and optionally the firmware using a compact flash card in CF1.
You should power down the panel.
Insert the compact flash card which has been previously loaded with a copy of the desired project from a PC or another panel into the CF1 slot.
Power up the panel.
Use the normal procedure used with a USB pen drive to restore a project and optionally the firmware. This is done by accessing the System Screen and using the memory/restore options. Pick PROJECT to just restore the project, or pick PROJECT and SYSTEM to update the project and the firmware.
There is one extra step. After the update is completed and the panel reboots, power down the panel. Remove the compact flash card. Then re-power the panel in order for the panel to access and run the new project.

FAQ ID: 1412
Why does my Cmore quit data logging?
The Maximum Number of Log Files with the same first four characters is 999 files.
For versions before 6.31 data logging will stop when this limit is reached. For version 6.31 and later data logging will continue but the oldest file(s) will be over written.
Internal file identification is restricted by the DOS 8-character-dot-3-character limit. Because of this, trend log files are identified internally by the first four characters of the screen name + tilde + a three digit number. For example,
TREND GRAPH EAST CHILLER TEMP_110925.txt and
TREND GRAPH WEST CHILLER TEMP_110925.txt
will be identified internally as TREN~001.txt and TREN~002.txt. As new log files are created each day, these files count against the same max of 999 files.
If Multiple Graph Objects appear on one screen, the files will be identified internally by the first Two Characters of the screen name plus the first Two Characters of the object name + tilde + three digit number.
To maximize file storage capabilities, consider using screen names that are unique in the first four characters, and using object names that are unique in the first two characters.
FAQ ID: 1417
What can I do to enhance the performance of my C-More panel?
1) Turn transparency off and change the background color to match the underlying object.
2) Turn off Stretch to fit and resize the bitmap in external software.
3) Animation will affect performance.
4) Rotation will affect performance.
5) Do not use visibility unless necessary.
6) Limit the use of gradient colors, use flat colors.
7) Reduce the number of objects on the screen.
8) Having objects that blink affects performance.
9) Checking the Bitmap Option in the panel manager will affect performance.
10) Do not stack or overlap objects unless absolutely necessary.
11) Limit the number of tags on the screen to what is absolutely necessary.
12) Make tags consecutive memory addresses for the screens that have a lot of tags.
13) Think about if you really need all of the Events that you have programmed. Each Event adds processing time to execute and possibly polling to the PLC for data.
14) Think about if you really need all of the Trend Graphs points. Each one will add to the processing time and to the polling time of the PLC.
15) Use Ethernet.
16) Using Full Screen popups will limit performance.
17) Use Compact Flash and use the SYS CopyLogs Tags to transfer data to the USB. We recommend using CF2.
18) Sending Email can affect performance.
19) Remote Access can affect performance.
20) Sounds can affect performance.
