IQANdesign 7.06 released
Updates for cyber security
This version introduces important updates preparing for IEC 62443 cyber security compliance on target modules.
Secure boot and secure update
IQAN-MD5, -MC4xFS, -MC4x, -XC4 firmware’s are now signed.
Signed firmware is required for installing on modules produced with secure boot.
IQAN-MD5 displays, -MC4xFS-M24 and -MC4x-M24 controllers, and -XC4x-M24 expansions will be produced with secure boot starting in 2026. Modules produced with secure boot will thus have 7.06 as minimum version (changing from 7.02 on MD5 and 7.03 on C4x-M24)
IQAN-MD4 and original version of MC4xFS/MC4x/XC4x will continue to be produced with bootloaders supporting old versions.
Major update of IQAN-MD5 firmware
MD5 firmware is restructured to strengthen cyber security and prepare for future improvements. When updating in the field, there are key points to be aware of.
- Upgrade of MD5 to 7.06 requires 7.05 in module.
- During update, all logs in the MD5 will be erased.
- After updating MD5 to 7.06, downgrade is not possible.

Project file size (.idax) increased to ~75 MB, to handle the update from 7.05 to 7.06. Clone files are smaller, ~30 MB.
Clones taken from MD5 7.06 or newer can only be sent to module with 7.06 or newer.

Other changes
IQAN-MD5 performance enhancements
- Reduced start-up time, time to show first display page reduced with ~1 second.
- Minimum application cycle time is reduced from 50 to 20 ms. The recommendation to use locate machine control functions on MC4 controllers remain.
Always send firmware before application
If an update is interrupted while sending firmware, the module is now able to restart with the old application, matching the old firmware. This reduces the risk of not having a working application if a version update is interrupted. As before the firmware is double stored, an IQAN module will always have a working firmware.

Customer support service by UserEcho
It says that after updating MD5 to 7.06, downgrade is not possible. Does this apply to other modules as well? If a program saved in 7.06 is sent to a machine with an MD4 and an MC43, or an MD4 and an MC43-M24, can they be downgraded after?
It applies to MD5.
Other modules you currently have at hand can be downgraded.
Just updated, and now we have an issue with the startup images. Anything set to transparent is now white.
7.05 this was not and issues, and if the same image is on any other display page on 7.06 it is good, Just on the splash screen it is an issue.
