Post by jeffgamsby on Accessing ModbusTCP addresses from python

Hi, I am new to modbusTCP and I am trying to access Input registers from codesys (3.5.SP13). The offset is 16#0000 and I am trying to access Channel 1[24] %IW24 to pull analog values. I am using pyModbusTCP and I need to supply a modbus address and the number of registers to read. What does 16#0000 mean in terms of the actual offset, how do I translate this number plus the channel to access this info via python? Any help would be appreciated, thank you.

I'm not really sure what you are trying to do, but maybe you are referring to using the CmpCharDevice library? When you "open" the connection to a device, you can pass flags. What helped me is to set the non-blocking flag. I'm not sure if this is what you are referring to, but maybe it helps: dFlags: DINT := CmpCharDevice.ACCESS_MODE.O_RDONLY + DINT#4000; // see details for flags: http://linux.die.net/man/2/open, + DINT#4000 is for non-blocking hDevice := CmpCharDevice.CDOpen(szFilename, dFlags, Result);

Thanks for your response! It seems like the VisuElems library has updated functions to the ones you used but apparently these older ones still work, even if I couldn't find them in the library documentation and they are also not suggested automatically by Codesys (when using Ctrl + Space). However, its precisely what I was looking for and it works. Thanks!

Post by manuknecht on Specify Input Configuration "OnDialogClosed" Action to only react to certain Dialogs
CODESYS Forge
talk
(Post)
I have a project with several buttons and dialogs. Most of the dialogs are opened using the Open Dialog action of the Input configuration of the buttons. Some dialogs are openend using the FbOpenDialogExtended FB of the Visu Utils library and the FbOpenDialogExtended FB is called in the Execute ST-Code action. I am also using the FileOpenSave dialog from Visu Dialogs which requires an OnDialogClosed action to read out. I realized that the OnDialogClosed action which is meant for the FileOpenSave dialog also triggers if a dialog is closed, which was previously openend using the FbOpenDialogExtended FB. Is there a way to detect which dialog was closed last and specify to which dialogs the OnDialogClosed action reacts?

Hi kdkwhite, for Word you still can use suggested code by using a union structure and crack down your Word to two byte as bellow: TYPE CrackWordToByte : UNION InWord : WORD; OutBytes : ARRAY [0..1] OF BYTE; END_UNION END_TYPE then define your variable as this type: udInput : CrackWordToByte; now assign your Word variable input to InWord and send OutBytes[x] to the mentioned method: udInput.InWord := WordVariableInput; Input := udInput.OutBytes[x]; Regarding your question about the code: actually 48 is ascii code of "0" and while 65 is the ascii code of "A" so in above code 55 + 10 would be 65.

CODESYS Forge

Hello everyone, I created a visualization with a lot of REAL, with one or two digits after the decimal point. This causes me problems in terms of rounding and memory... is it possible to display an integer with a comma, like with PROFACE or SIEMENS? It's just an "abuse" of display, the comma is just on the visualization. This limits the memory (16 versus 64 bytes) and rounding is easier to manage... See print screen on proface software THANKS

Post by dwpessoa on CNC Jumps G20 - SMC_NCInterpreter and long time to process
CODESYS Forge
talk
(Post)
I am studying and developing a Softmotion+CNC system for a machine that executes multiple pieces. The G code program is written by the machine operator and each cycle execute 1 piece. The programs are large, exceeding 1000 lines and using up to 8 axes (X, Y, Z, A, B, C, P and Q). The machine needs to run cyclically, executing N pieces (selected by the Operator)... so I tested it using Looping and counters (G36 G37 and G20) and it worked, but it takes a long time to process, and the more pieces I need, the longer the processing time and this is totally impracticable. I found this solution which was very good, and for a few cycles it works well, but for 99999 pieces of a program with 1000 lines, it doesn't work very well... Another solution I tested is to maintain the interpolator with an automatic restart, that is, I load the program without looping (without G20) and give it another start as soon as it finishes. This partially resolved it, but there is still a delay in processing SMC_NCInterpreter in each restart :(. Another solution I thought of is to manually create the SMC_GEOINFO structure and then reuse it, avoinding the Interpreter, but reading the documentation and checking the structure filled by standard blocks, I noticed that there doesn't seem to be a "JUMP" function in the structure! In other words, the SMC_NCInterpreter actually keeps copying and copying the program section for each jump (G20)... If I repeat a 10-line program 1000 times, I will have a structure with more than 10000 lines... possibly this is the cause of take so long to process. Has anyone ever had a problem like this? I believe the same thing happens with typical applications with manipulator robots using Codesys in continuous cycles, and I would like to know if there is any solution, or even if I am misinterpreting the G20 question in SMC_GEOINFO. Thanks!

I found that the MQTT had an error: MAX_RECEIVE_BUFFER_SIZE_EXCEEDED. And MQTT hadn't reconnect since then. I tried a cold and a warm reset but nothing helped. How can I solve this? Regards, Paul

CODESYS Forge

Hello, I would like to have, if possible, some clarification on this function. That is, I would like to understand if it is useful for managing, fom my development PC, the RTE runtime executed on a remote control. This is what the help says: Remote PLC: Opens the Remote Configuration dialog. By enabling or disabling the Control remote PC, not local option, you determine whether a PLC is used that is on a remote or local PC. Accordingly, the menu commands Start PLC, Stop PLC, and PLC Configuration refer to the local PC or a PC reached on the network. For the remote PC, specify the Target PC address, Port number, and a Timeout value (in ms) for the connection (Remote Timeout [ms]). But does this mean that I also need to install the RTE runtime on my development PC? Is it possible to have some more information? Best regards Roberto Caponi
