Firmware is a type of software that is embedded into hardware devices to control and manage their operations. Unlike regular software that can be easily updated or removed, firmware is typically stored in non-volatile memory, such as ROM or flash memory, and is essential for the device to function. It provides low-level control over the…
The allocated memory for “Data, Input, Output, Memory, Code” is the maximum size of a CODESYS IDE project. Project files may not exceed the available memory on the cMT series’ CODESYS runtime, or else “Out of code memory…No download possible” errors will occur. Memory limits on CODESYS firmware revisions prior to v20240703 are as follows:…

NOTE: Advanced mode is required to reverse the order on the SQL Table. By default the SQL Query Result Viewer will visualize data in ascending order. To change it to descending order will require enabling Advanced Mode under [Data/History] > [SQL Query] > double click on an SQL Query instance > Enable [Advanced Mode]. Once…
To disable internet access over the HMI’s ethernet port, set the gateway and DNS addresses of the WAN port you want to disable to 0.0.0.0 in the system settings for your device under the Ethernet port Network settings:

The built-in CODESYS runtime for the cMT and cMT X series supports the following protocols for communicating with external party devices: When structuring a project in CODESYS IDE for the cMT Series’ built-in CODESYS runtime, users are advised to utilize the following drivers: CODESYS IDE Device Recommended Version Ethernet adapter (added above any drivers for…
Bridge Mode allows a device to function as a network switch, forwarding traffic between LAN ports without modifying packet data. This creates a seamless connection between devices, enabling communication as if they were on the same network. All LAN ports operate as a single network segment, relaying traffic without performing NAT. This mode is useful for extending networks, reducing bottlenecks, and maintaining transparent data flow. Proper configuration of Bridge Mode helps prevent unintended network issues and security risks.
A compiled project file can be decompiled to extract the project file and create new library files for the embedded graphics. This will create a new .emtp or .cmtp (editable project file) that can be used in EBPro. There are 3 primary file types for project files used in EBPro:

There are many methods that can be used to set a string value to LW registers in an EasyBuilder Pro project. A useful method with a cMT series device is by using the Action Trigger object. Other methods include using a similar strategy with the Set Word objects, or even a Macro using the SetData command.

Yes! You can have each LAN port on a cMT or HMI configured for a different network or subnet, in fact, we recommend doing so to keep the ports from conflicting.

The specifics will likely differ based on which device you’re specifically working with, but in general, LAN 1 is the port you’d use for a network connection that goes out to the internet, where LAN 2 is strictly for Local Access Networks. In general, we recommend keeping to LAN 2 on your device, unless you…

When downloading a project using a newer EBPro version or using a particular font you may likely hit the “building font file failed” error message when compiling your project: Certain fonts, such as Bahnshrift, are no longer supported in newer versions of EBPro. If you are experiencing these errors there are two ways to workaround…
