Moving from Mervis 2.0 to 2.1
When moving from Mervis 2.0 you might be facing some issues:
I have HMI created in the external HMI editor and want to move it to the new IDE
Importing project created in the external HMI editor is not possible. You have to either stick with the external HMI editor and use the new IDE to upload the HMI as you were used to or design the web interface from scratch in the HMI editor integrated into the Mervis IDE.
Cannot control relays and digital outputs of your Extensions (the variables are red)
This is caused by using different registers in prototypes v2.0 that are not implemented in the Firmware of your extensions. To fix it, you can either update the firmware of the extension or use prototypes <2.0 (but Mervis will complain about using obsolete device).
Mervis warns about a used obsolete device
Mervis reports message “Warning Obsolete HW device “Neuron S103” is used. This device should be manually replaced by a suitable device from the current HW library.” warning users about using obsolete device prototype. This is caused because the IDE, in which the project is currently opened, contains a newer version of devices so the older version is marked as obsolete.
You can ignore the message if you do not mind or you can move to newer prototypes which are part of the IDE. However, this does require some work depending on the complexity of your project.
Upgrading firmware in Extensions
When using device prototypes v2.0 (older prototypes are marked as obsolete) a firmware v5.14 or greater must be used. The firware can be updated by the Extension FW tool via USB-RS485 converter.
Moving your devices to the current version
how to do that properly? Have you used Autogen on the whole device or not?
