Hi there, I have a Keyence bar code reader connected to my plc through Ethernet/IP. The Bar code is 20 digits long (like 30100790020493036016), the scanner reads it correctly (I can verify that through the keyence software) but when it sends it through ETH/IP, it doesn't fit into a 64 bit variable and it trunks the data.(I've tried ULINT and LWord without success). When I loaded the EDS file, the read variable was defined as a byte with 128 bits length, which is quite strange for me. (see attached picture) How do I manage this variable? Thanks!

My guess is that's a STRING, not an INT type. And it's 128 bytes, not bits

I think more information is needed to help solve the issue. Can you list the exact steps to reproduce the issue? What version of Codesys are you using? Did you add a persistentVars object to your project? I would recommend browsing all instances of the retain variable to see all possible writes to the variable in question.

Is there a variable indicating that a gearing or camming operation is pending? For instance MC_Gearin has beeen triggered, but starting point of master axis to start the sychronisation movement is not reached yet, so the slave axis is just waiting for this. I should be able to differ between a pending and active gearing or camming

So I think I've found a way to do what I want, but its a not as simple as I thought it would be. Essentially I've got to put my "logic" that decides what the GVL variable should be at the start of every task (rung 1). Then regardless of what the force is the variable will be set to what the logic decides.

I also thought that if I had logic writing a value to this variable, then it would override the force anyway, since I thought that the force request was only applied at the beginning and end of the PLC scan. But this doesn't seem to be the case, the force persists throughout the logic regardless of what I write to the variable with logic

It seems to only log the last usage at initialisation and that is it? how do i gain ongoing access to the time variable as the code is running? Thankyou.

Post by arundara on Variable Sync Issue In Soft Plc Redundancy
CODESYS Forge

(Post)
Hello, I was trying to create a redundancy POC for our application where we read data from few modbus tcp devices. As there is a limitaion that modbus tcp device support only for single master device, we wanted to test how the variable sync happens in redundancy mode. For that i have used the redundancy sample code added a variable "b" under a condition. What i observed was while active controller is running, if passive controller is powerup, passive controller is able to sync all the data configured for redundacny. But after that the variable data which resided under a condition is not synching from active to passive controller. I have attached the image where i have highlighter the variable. Can some help me to understand how redundacny work in codesys soft plc and if there is a solution to sync variable which are under condition, please explain the same or suggestion to achieve the same. Hardware - Raspberry Pi (2 qty) Redundancy licence used - yes in both controllers. Codesys runtime - 4.9.0.0 Codesys software version - V3.5 SP19 if i have posted this question in wrong section, please do let me know in whcih section i have to post this question.

Please see or Online Help on how to initialize variable before using them: https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_pragma_attribute_global_init_slot.html Regarding the Attribute global_init_slot: You can use this pragma to influence the order in which signatures are processed during global initialization. It can only be applied to signatures. By default, the initialization sequence for variables from global variable lists is undefined! However, if, for example, variables from one list depend on variables from another list, it is necessary to initialize one before the other. (Aee OLH and Syntax) The placeholder <slot> must be replaced by an integer value that defines the position in the initialization sequence.</slot> The default value is 50000. A lower value causes an earlier initialization! If several signatures have the same value for the 'global_init_slot' attribute, the order of their initialization remains undefined! Cautious application should therefore be considered! Example: The project contains f.e. two global variable lists GVL_1 and GVL_2. The global variable "A" is part of the global variable list GVL_1: {attribute 'global_init_slot' := '300'} VAR_GLOBAL A : INT:=1000; END_VAR The initialization values of the variables "B" and "C" of GVL_2 are dependent on the variable "A". {attribute 'global_init_slot' := '350'} VAR_GLOBAL B : INT:=A+1; C : INT:=A-1; END_VAR So if you set the 'global_init_slot' attribute of the global variable list GVL_1 to 300, i.e. to the lowest initialization value in the example, then it is ensured that the expression "A+1" is well-defined at the time of initialization of "B".

Regarding to your application: When clicking in the web visualization, the boolean variable will be tapped for both buttons. The LED in the web visualization lights up as long as the variable is true The used variables should come from the GVL, ad/or thePLC_Prg. We see no difference or problem in both projects: You have created a visuelement Push button a a tapper, that is supposed to control the variable in this way as expected. This is also reflected (switching Bool from false to true) in the program code, as well as in the (GVL declared) variables. Wherever the misunderstanding comes from: no, this is not memory or license related. Our best guess: it is probably more of an applicative/conceptual implementation.
