Post by comingback4u on Memory Address Overlap
CODESYS Forge

(Post)
Hello, We use a controller that comes with a bunch of predefined faults. These faults are considered active and historic. They are a 32 byte array but only take up 26 bytes of data. Because of this the historic faults start at address 26 instead of 31. Active faults variable take up address location 0 to 31. Historic faults variable take up address location 26 to 57. Because of this overlap I get an error that these overlap and it wont allow me to download to my controller. This isn't an issue in 3.5.5.4 but becomes an issue in newer version. Is there a way to turn this off? If I change the address location, the historic faults then become broken without doing some manipulation in the code. The software will build just fine. Thank you for your time.

I'm currently reworking the controls on a cnc press brake and wanted to load various recipes as programs to run. I'm using a 2d array of REALs to store the X and Y coordinates as well as some other program parameters in a recipe. I'd like to store all of the recipes on a computer used as the HMI that way the text files can be edited and uploaded offline. I'm using Automation Directs P2CDS-622 Can this be done through webvisu? If not would a license for Codesys HMI SL on the computer allow me to accomplish this? I've attached the Project File Thanks, Spice

Post by garyl on Comments in arrays and assigning RST coil's to 600 outputs

Hello all, im working on a project that requires me to convert an old automation direct DirectSoft PLC d2-250-1. One of the problems im encountering is that all of the comments are attached to members of the different addresses. When i convert the addresses (1777 "C" registers, 777 X registers, and 20,0000 V registers) im running into difficulties keeping the inputs/outputs correct since they are missing documentation. Is there a good way to retain the comments of the indexes in the array? Secondly, initially i was declaring the "C" and "V" addresses individually and this worked to retain the comments as to which register did what, however i ran into a problem when one rung reset (or set to 0) approximately 600 C Addresses. Since each tag is separately declared this proved to be nearly impossible without a literal wall of code that attempted to crash the program. So i converted all of the registers (C,X,Y,V) into separate structs, declared them as arrays and pointed all of the original call outs in the program to the newly defined structs. However i have now lost comments and the program is very hard to follow. Thanks for any help with this issue.

Thanks! As far as I can see, the client can only send words. And on the server side there are an array for each of the functions: bool for coil and discrete, word for holding and input registers. I assume I can use holding register, then use bit mapping on the words instead of coils. But I really want to use the FC15/coils.

Hi everyone, I just created a very simple library without any code and, added it to my very simple project. after adding this library, I get an error when I try to open "Symbol Set" in "OPC UA Server" in "Communication Manager". Here is the code of my POU in the library: FUNCTION_BLOCK POU VAR eCommand : (CMD_NONE:=0, CMD_RESET:=-1) INT := CMD_NONE; END_VAR Attached is the error that I get. I also noticed that by removing the enumeration variable above (eCommand), I can open the "Symbol Set" again. Anybody has any idea why this error is raised and how could I use enumeration variables without error in "OPC UA Symbol Set"?

Hello, I have a simple TON timer. It is watching prime loss for a pump. The operator can set the delay via the HMI, it is an integer (seconds) As the TON uses milliseconds, we then multiply the entry by 1000 to get seconds. Seems simple, but... VAR PrimeTimer : TON; primetime : INT; END_VAR PrimeTimer(in:=State>0 AND FlowRate<MinimumFlow,pt:=INT_TO_TIME(primetime *1000)); For an entered 15 seconds (VAR primetime:=15;) the timer reads 49d17h2m26s760ms !!!! What am I doing wrong?

To search for an exact phrase, put it in quotes. Example: "getting started docs"
To exclude a word or phrase, put a dash in front of it. Example: docs -help
To search on specific fields, use these field names instead of a general text search. You can group with AND
or OR
