Post by transmin01 on CANbus issue ^{CODESYS Forge talk (Post)}
Hi, I have been trying to get a CANbus device working with Codesys 3.5SP19 patch1 via a Beckhoff EL6751 gateway without success. I have the CANOpen_Manager and CANopen device configured but this will not run. Is there any code required to kickstart the CANbus comms into action? Regards Trevor

In the example project, you can see that a CAN.CANAreaReceiver is used which has an VAR_IN_OUT reference to a RECEIVER_AREA structure. This structure has a dwIdStart and dwIdEnd to filter a range of ID's and process them through the referenced msgProcessor.

You need to create a function around this function to check the dialogs you use in your program. That's the way i have done it.

Well. One can do that, I have found a python script which can modify /etc/dhcpcd.conf and I suppose there is a way I can execute it from CODESYS and it seems to be the only way

anyone found any sample code for this library? I'm trying to work with AsyncManager but the documentation is not helping? Surly, codesys when they coded this library they had a sample project to test and simulate the functionality for this library. can you share it please ?

I'm worried that the Core SE (which I was originally going to go with) will not be straight foward in terms of setting up the HMI visualization. This is for an offline application, if that matters.

Post by arundara on Variable Sync Issue In Soft Plc Redundancy ^{CODESYS Forge talk (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.

Post by ofey on Testing of Codesys program ^{CODESYS Forge talk (Post)}
Hi! I thought to hear what you guys think is the best way to test the program in my scenario. I have some PLC programs that have been made and deployed on different PLC's. The program has added the specific devices and IO that is applicable. I have made a test environment for everything outside of the PLC, ie. the same SCADA system that is talking to the PLC, and a program running locally is simulating the plant (level regulation of different tanks). Pr. now I have had to manually change the variables that are reading/writing values from the IO so they read/write via OPC instead. I also have to change the device tree from the specific PLC rack, to the soft PLC. So I kind of end up with two different programs that I have to maintain. I was just wondering if you believe there is an easier way to do this. So I can have the exactly same program and kind of switch between the soft mode, and the "real" mode.
