Hi, I realized that if I replug the power supply the persistent variables lost their value with the new software too. Cold reset do not affect the variables value but hardware reboot still reset the values. Application Composer can't be activated. What is the solution?

It's good that you've found a workaround. But it's bad that you need one. The array length auf my struct is 16. My struct also contains other arrays of structs. It contains a total of 1716 variables. I have tested saving and loading extensively under version 4.3.0.0. It looks good. I couldn’t find any problems. Maybe it helps to reinstall the update (see previous post). Otherwise you could try my test project (first post). This should work with version 4.3.0.0.

Hello, this seems to be a known issue, but persistent/retain variables don't seem to work properly on RevPi devices. Is there a workaround to this? All I need is for a few configuration variables to be remembered through power cycle.

CODESYS Forge

Why will it retain the sum value from the last call? This is how PLC work. Usually variables only get initialized after a download or a reset (i.e. power loss). RETAIN variables are saved in a special kind of RAM and keep their value after a power loss. To initialize variables on every call of your FB use the VAR TEMP block. VAR_TEMP sum : INT; END_VAR

Post by stuartjr on POU Private variables
CODESYS Forge
talk
(Post)
Pretty sure I know the answer, but thought I would ask just in case. Is there a way to set variables declared in a POU to private so that they can not be accessed from other POUs. I tried using the library pragma, but that just stops the variables being displayed in the selection tree. My compiler version is 2.3.9.62 if that's relevant, and I'm using an ABB AC500 V2 PLC. Cheers

Post by pernockham on Is there a pragma for init/instantiation of local variables in FB (like in Methods)
CODESYS Forge
talk
(Post)
Im using a pointer as input for a FB and for convenience I like to use 'referenced' variable internally. I use this setup in methods which works because internal variables are instantiated for each call. In a FB these variables are instantiated and initiated for the first call only. Is there a pragma/attribute available that changes this behaviour to mirror a 'method'-call?

You should ask IFM to provide you with the correct version of their controller packages. Then after you have installed this, you can select the correct version of the controller by right clicking on it in the device tree, update device, enable the option "Display all versions" and then select the version which matches your controller. Alternatively you can ask IFM to provide an update package which can update the runtime version on your controller to 3.2.0.0.

To search for an exact phrase, put it in quotes. Example: "getting started docs"
To exclude a word or phrase, put a dash in front of it. Example: docs -help
To search on specific fields, use these field names instead of a general text search. You can group with AND
or OR
.
