Post by alexgooi on Function Blocks and arrays of function blocks ^{CODESYS Forge talk (Post)}
Hi Jack, I think you have to look at a FB in a different way. A Function block (Class) can contain its own data. In other words don't define loose data in your GVL, but define a instance of a FB (Object) in your GVL: Example: Function_Block Basic_Class VAR_INPUT Open_Command: BOOL; END_VAR VAR_OUTPUT Opened: BOOL; END_VAR if Open_Command then Opened := TRUE; ELSE Opened := FALSE; END_IF Global Variables Objects: ARRAY[1..100] OF Basic_Class; //Here you ar defining you objects END_VAR In your code you can directly acces the data and couple it to the IO: GVL.Objects[1].Open_Command := %IX0.0; %QX0.0 := GVL.Objects[1].Opened; //To call the code itself use: GVL.Objects[1](); If you want to take this a step further you are also able to add methods and properties to the FB/Class end thereby creating a OOIP program

You have to update the device in your IDE to 3.5.14 or you can contact your Codesys runtime supplier to know how to set the connected system to 3.5.19

Post by riccardo on VisuElems.CurrentUserGroupId is not stable ^{CODESYS Forge talk (Post)}
GoodMorning everyone. I have a system that, in case of alarm, have to block. When the operator logs in must have to acknoledge the alarm and should operate in the system freely. To perform this I detect the logged User by (VisuElems.CurrentUserGroupID <> 0) with a similar code to the the following: PROGRAM AlarmMngt VAR alarm : BOOL:= FALSE; Ack : BOOL:= TRUE; PushBottonOpening : BOOL:= FALSE; Valve : BOOL := FALSE; Flag: BOOL := FALSE; END_VAR IF alarm AND Ack AND (NOT Flag) THEN valve := FALSE; PushBottonOpening := FALSE; Ack := FALSE flag := TRUE; ELSIF (NOT alarm) AND Ack THEN flag := FALSE; END_IF (* if the system is in alarm but there is a logged operator that acknowledge the alarm the system allows the valve opening.*) IF (VisuElems.CurrentUserGroupID <> 0) AND Ack AND Alarm AND PushBottonOpening THEN Valve := TRUE; ELSIF (VisuElems.CurrentUserGroupID = 0) AND Alarm THEN valve := FALSE; END_IF The problem I have is in the last 5 lines of the code: Even if there is a logged in user, the GroupID variable is subjected to a refresh that cyclically set for an instant it to 0 and this close the valve making difficult to the user to work Now I solved it creating a time hysteresys cycle but it is not a good solution. Someone is able to explane me why the GroupID variable is sobjected to this refresh and how to stabilize to avoiding it? Thank you in advance, Riccardo

Goodmorning TimvH, Thanks for the reply. I don't know if your solution solve my trouble yet, I am going to see the link you sent me. In the mean time I try to explane better what I need to do. I have a turbine system that get in alarm under some condition (E.g low speed of turbine) and block the itself. When the system is stoped there is no speed turbine and the system cannot start. To give to the operetor the possibility to bypass the alarms, there is an acknoledgement alarm pushbutton. This bypass must not work for everyone but only for those client that perform the login by (User Management). Furthermore, if the user perform the (manual or automatic) logout in alarm conditions, the acknowlegment must be annulled and block the system again. To do this, I need to know if an operator is logged in the page and is working to fix the problem; otherwise the syste must autoturn off again. Now I go to study your solution, if I have explaned better and you have another idea tell me please.

From bash I usually see codesyscontrol.service as the runtime service. Taking a step back, I guess you used Tool > Update RaspberryPi SL interface to install the runtime: what does the info popup window tells you about your destination system?

is your pointer set to the correct visu client? set a breakpoint in your client iteration and step through the active visu clients like programming system, targetvisu, webvisu,... and check the last usage value of each client

Post by rossanoparis on Clarifications regarding the appropriate runtime system to use ^{CODESYS Forge talk (Post)}
Hallo all I would appreciate some clarifications regarding the appropriate runtime system to use. I've been using 'KUNBUS CPUs' and 'CODESYS Control for Raspberry Pi MC SL' for the last 4 years. Recently, there have been some changes in the CODESYS licensing policy. [ https://store.codesys.com/en/howto_applicationbasedlicenses ] My questions are mainly two: 1) If I need to start a new project using 'KUNBUS CPUs', which is the correct runtime system to use. 2) Old projects built using 'CODESYS Control for Raspberry Pi MC SL' should be updated to another RT system? Current RT systems ... a)CODESYS Control for Raspberry Pi MC SL b)CODESYS Control for Linux ARM SL c)CODESYS Virtual Control SL May I count on receiving an explanation to understand the differences among the runtime systems listed above? A detailed and well-organized answer would be greatly appreciated. Kind regards Rossano

Post by rossanoparis on Clarifications regarding the appropriate runtime system to use ^{CODESYS Forge talk (Post)}
Thank you @TimvH It is clear that licences are application based and now thanks to your reply I could understand the meaning of RT systems. The RT called "CODESYS Control for Linux ARM SL" can be deployed on a generic debian based ARM system. The RT called "CODESYS Control for Raspberry Pi MC SL" is more specific for Rasberry HW. Did I understand correctly? Regarding the RT called "CODESYS Virtual Control SL" despite its description it is not clear to me when to use it. It seems that a project created using such RT system can be deployed on any HW. It sound good obviously, as it means that it is possible to realize a completely abstract project from its hardware. The only limit could be represented by the need of using a specific HW or OS feature, in that case a more specific RT system should be chosen. Is my last consideration correct? Regards Rossano

This is the operating system and has nothing to do with the runtime. Unless you use 64bit commands. You can see for yourself that you have errors with 64bit compilers

I haven't actually found an answer yet. It happens quite rarely, so testing and diagnostics are complicated. I've updated the software with every SP and add-on updates released, but it's probably a Kernel driver issue.

Arrays with variable lengths are a bad idea. This makes your system unstable and can lead to crashes. Declare your array large enough to reserve enough memory

A task in CODESYS normally is a task of the underlying operating system. If your os is preemptive and the sheduler is configured accordingly a CODESYS task will be preemptive too.
