C-More HMI Drop-Down Create

The C-More can create a drop-down menu. A drop-down is a menu that offers a list of options. The currently selected item in the list is always displayed. When the visible item is selected (touched), other things from the list "drop-down" into view, and the operator can choose from those options.
We will be creating a drop-down menu using a C-More Micro HMI. (Human Machine Interface) This could also be done using the EA7 or EA9 C-More HMI controllers. The EA3-T4CL will be communicating to a Click PLUS PLC. A ladder logic program in the PLC will control the operation of this operator interface drop-down menu. Selecting a question on the drop-down will give an answer on the corresponding Lookup Text display. Let's get started.

• Free downloadable programming software
• 482 x 272-pixel display (WQVGA) with up to 40 lines by 80 characters of text and graphics
• 32K colors
• 14MB memory
• Built-in USB type Micro-B programming port
• Built-in RJ45 Ethernet Port
• Built-in 15-pin serial communications port
• Built-in RJ12 serial communications port
• Built-in Alarm Control setup that activates beep, back-light flash, customized alarm banner, and red LED blinking
• 0 to 50 °C (32 to 122 °F) operating temperature range (IEC 60068-2-14)
• NEMA 4/4X, IP65 compliant when mounted correctly, indoor use only
• UL, cUL & CE agency approvals
• 2-year warranty from date of purchase

Hello, I am communicating a s71200 with a nextion screen through a CM1241 RS232 module and a max3232 to convert RS232 to ttl. I have already managed to receive in the plc by pressing buttons created on the screen and numbers as well, with which I have achieved the reception part. However, when trying to send from the s71200 plc to the screen so that it shows me a numerical value in a field, I cannot get it to send and it does nothing, the Tx led on the CM1241 RS232 only blinks, so something is sending but it is not what is correct. I have looked for information about all this in the instruction set but I can't find where I think the problem is, which is in the character frame. Does the display need a frame of characters or bytes to know or start receiving? I am trying to send in hexadecimal.

The C-More human-machine interface (HMI) panel currently comes in two different versions. The C-More Micro and the C-More EA9. Each of these families of HMI panels has its own software to program the controller. The full software packages for the C-More are free to download.

Note: The C-more EA7 series of controllers are not promoted anymore. The EA9 series has taken its place. EA7 project files can be converted into the EA9 series using the software.
