Question:
Can the Asian character sets be used on the C-More Micro panels?
Answer
The C-More Micro panel does not have the resources to support use of the full Asian character set.
For applications that require the Asian character set support, the full size C-More is the appropriate product.

Question:
Can a C-More Micro be used with a CompactLogix CPU?
Answer
Yes, but the EA1 series C-More Micro does not have an Ethernet Port so it must use DF1 or DH485 and use SLC addressing mode. It cannot use Tag Based Addressing.
If you are using a EA1 series 3" C-More Micro you will have to add the EA-MG-SP1 (retired part). The built in com port (RJ12 connector) cannot be used with the AB protocol. You can find more help on how to do that in the C-More Micro Help topic CMM310.Open the help and search for CMM310
Consider using the EA3-S3ML instead.

Question:
How can I make the PLC change the screen on the C-more Micro panel?
Answer
Application note AN-EA-005 describes how to do this for both the C-more and C-more Micro panel.
There is also an example program EP-EA-001 (with PDF copy) that shows how it done.

Question:
I need to use an EA-MG-SP1 adaptor to extend the distance my Cmore Micro will be from the PLC. Is there a breakout option for the communication wiring?
Answer
Yes. If you purchase the ZL-RTB-DB15 and the ZL-DB15-CBL-2 you can connect the Ziplink module to the 15 pin connector on the EA-MG-SP1 and you will have individual wiring terminals for all 15 pins of the serial port connector. This is convenient for wiring RS-422 or RS-485 connections.

Question:
My C-more Micro is not showing the same floating point number as my (PLC, Spreadsheet, other platform). Why is this?
Answer
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, which is not rounded.
The following example uses this IEEE-754 Floating-Point Conversion 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
- At the bottom of the page, select "[ Convert IEEE-754 64-bit Hexadecimal Representations to Decimal Floating-Point Numbers. ]"
- Enter "4159BE76" and click "Compute" and you will get a result of 13.608999
This shows that 13.609 is not a pure number but has been either truncated or rounded since the binary pattern of 0x4159BE76 is being used.
