Post by ben1 on How to write multiple coils (Modbus FC15) ^{CODESYS Forge talk (Post)}
If I am understanding what you are saying, then yes that would be your problem. I would create an array of bools on the client side for the transfer and try that. Or if client can't be changed then use words on server and unpack. But I am not sure if you or I are mis interpreting but it sounds a bit jumbled. I don't know what you have control of, but, if you are turning on BITS in the server, you should write to BITS in the client with a Function 15. If you are writing to WORDS in the server, you should write to WORDS in the client with a Function 16.

Post by climblinne on OPC UA Method - How to wait for result? ^{CODESYS Forge talk (Post)}
Hello, I am already able to run an OPC UA method in Codesys. Now my question, how can I interact with other tasks (e.g. read an SDO from EtherCAT and return it by the function)? The OPC UA method seems to be called only once (I tried to return BOOL or UINT values). Up to now I only found to do a while loop to wait for the result of the other task. Is there a better way to do it? Is this the way OPC UA functions should be used (for "not too long" function calls) or should I use another mechanism (method: Start, event: Finish, method: getResult)? Regards

Post by sawicpx on CANbus Remapping PDOs During Runtime ^{CODESYS Forge talk (Post)}
Hello, I am working on an application where I need to remap PDOs to a different CANopen object during runtime depending on what value is at a specific register. I have gotten to the point where I put the device into Preoperational State using the CIA405.NMT function. I then reconfigure the PDO 180x and 1a0x obejcts usings SDOs to point to a new canopen object on the device however when I go to restart the Device from PREOP to OP using the CIA405.NMT function the device is reset back to the original configuration as per the initial setup. I am wondering is there any way to change the PDOs at runtime is there some more functionaility I can access to do this. Any direction is appreciated!

Post by jdjennings1962 on Trouble accessing Math functions in OSCAT library ^{CODESYS Forge talk (Post)}
Hi all, I am trying to utilize the ARRAY_SDV standard deviation function, part of the Math group in the OSCAT library downloaded from the CODESYS store. My Codesys version is 3.5.19.10. When I add the OSCAT to my Library, it shows a subset of the library (Standard) as fully installed and signed (see pic). However, the Math functions are not in this Standard group. The Math functions I need can be viewed as source code in the full OSCAT_BASIC, though this the symbol next to this library suggests it is source only and not fully installed. When I try to declare an instance of the ARRAY_SDV function in a program, it is not known. I have tried reinstalling and Building . . . Any help would be greatly appreciated. Jeff

Post by jeroen on Ramp function ^{CODESYS Forge talk (Post)}
Hi, Found a nice ramp function in the OSCAT lib (FT_RMP), but is there a nice way to 'set' the output to the current input as form of a reset. The reason for this, is that I want to set up a ramp for a pressure control input that should have x Bar/sec linear rise input. The only option (or code it by hand) I found is this OSCAT FB. Any other options? Just need to increase a value by x Bar/sec from let's say 250Bar (as start) to end 1500Bar. The Oscat ramp will always start at 0 when enable is off (FT_RMP.Rmp := FALSE)

Post by toby on Ethercat Servo Setup ^{CODESYS Forge talk (Post)}
Hi everyone, so a little update to this, I've come back to this project in the new year, and got it working. Yeah!, However, now with the new licensing setup, I need a new SoftMotion license, but it doesn't seem to be compatible with the previous Raspberry Pi SL license. Has anyone had any luck with Raspberry Pi and SoftMotion_Lite? Specifically the licensing of such? My customers new installation needs to be rebooted every 30min which is causing headaches! Another option is to not use the SoftMotion function blocks, and control the EtherCat amplifier directly, but I'm not sure how to do so. Does anyone have a specific example project of how to control a servo without the use of the SoftMotion function blocks? Thanks everyone for any assistance rendered. It's very much appreciated! Toby

Post by timothyzalusky on Strange Behavior on Raspberry Pi ^{CODESYS Forge talk (Post)}
Hello, I am seeing some weird runtime behavior related to the EQ function on a rapsberry pi based system. I have attached a screenshot showing the strange latching I am seeing on the EQ function, and I have not seen this behavior before. I tried freshly restarting the runtime and it has this same behavior. Anyone seen this? I am on 3.5.20 with the latest runtime installed. Basically, as soon as it hits one of those EQ's in the program, it latches effectively locking the output on. Any input from the Codesys team would be appreciated as well as anyone that might know what I am seeing.

Hi, Softmotion Robotics does not support tracking in/out to dynamic coordinate systems with relative movements. Is MC_MoveLinearAbsolute an option? See SMC_RELATIVE_MOVEMENT_TRACKING_CS in https://content.helpme-codesys.com/en/libs/SM3_Error/Current/SM3_Error/SMC_ERROR.html Concerning the other error: Do you use any motion function blocks of SM3_Basic to move a single axis of the robot in your application?

Post by timvh on Array to String ^{CODESYS Forge talk (Post)}
The string_Util_Intern is not the library I referred to. With a CONCAT function (also with the string util library) a search is done for the NULL character. If you concatenate 20000 characters to one string, then the longer the string, the longer it takes to find this NULL character.

Hi, you could calculate the position/dynamics of the slave axis yourself and use one of the function blocks SMC_FollowPosition/SMC_FollowSetValues to move the slave axis. https://content.helpme-codesys.com/en/libs/SM3_Basic/Current/SM3_Basic/POUs/Movement/Direct/SMC_FollowPosition.html https://content.helpme-codesys.com/en/libs/SM3_Basic/Current/SM3_Basic/POUs/Movement/Direct/SMC_FollowSetValues.html

Hello jacobwago, I believe that the limit is fixed in the editor, but not in the driver package. There seems to be no link between the driver setting and the editor. Otherwise, I don't know why the input (>10) is blocked, but the function is available. Unfortunately, I cannot offer you any other solution apart from the one mentioned above. Kind regards

I found some structured text code which contained this statement: bHidden:= TRUE(*NOT _somevariable*) I haven't seen TRUE() used like a function before, and I also haven't seen the enclosing asterisks * * before. What do they do? (sorry if this is a duplicate question, I don't know what words to use to search for this syntax)

Post by trusty-squire on Strange problem with the ‘MC_SetPosition’ function ^{CODESYS Forge talk (Post)}
Just a stab in the dark, but you might want to check the Dynamic Limits (accel, decel, velocity, jerk) in the Codesys SoftMotion device configuration, as well as checking similar limits on your servo drive? Are you seeing any errors, or does the MC_SetPosition FB get marked as complete?

Hi Gustavo, can you reduce the problem to a project that reproduces the issue without the real servo drives? (You could set the servo drives to virtual and strip away as much as possible from the application.) If you can attach a project, we will have a look. Best regards, Georg
