Post by bitwitch on Einheiten umrechnen, Numpad und Eingabegrenzen ^{CODESYS Forge talk (Post)}
Das Codesys-Objekt 'Einheiten umrechnen' wirkt auf timeVar (TIME) z.B. innerhalb eines Visu-Rechtecks und funktionier in den Grundfunktionen einwadfrei. Die Ausgabe der Std. von timeVar läuft. Beispiel: Bei t#3d2h10m wird wunschgemäß 74h (volle Std-Anzahl). Die Grenzüberwachung Max= 10 funktioniert nicht, da die Angabe scheinbar ms erwartet (arbeitet mit 10ms). Irgend wie muss man jetzt codesys davon überzeugen, dass auch für Min und Max die Einheitenumrechnerei wirken soll, wobei die Eingabe der Grenzen in Std erfolen muß. Hat jemad einen TiPPPPPPPPP?

Post by paro on OPCUA array max length? ^{CODESYS Forge talk (Post)}
I think the amount of data is already relatively high and maybe it has something to do with that? Maybe also the CPU load of your device? an array with string(5000)? and have you tested with how many array elements it still works?

2000 works. When testing with UA Expert there is a timeout from the OPCUA Server when trying to subscribe to the variable CPU do not seems to be to affected. The memory(RAM) however is building up

Post by timvh on CAA SerialCOM - hCom Reset max value 1023 ^{CODESYS Forge talk (Post)}
You should only open de COM port once and then leave it open. This hCom should not keep on incrementing. (off course when you are done communicating, you need to close the COM port)

Hi TimH Thanks for the information, I thought that was the case so have stepped through the code and found an error that wasn't closing the port, therefore hCom was increasing. Thanks

Können Sie mir sagen, ob Sie wussten, wie Sie das Problem beheben können? Meiner Meinung nach müsste ich vielleicht die „Stackgröße“ ändern, die in früheren Versionen von CODESYS erlaubt war

Post by peterned on Array to String ^{CODESYS Forge talk (Post)}
max. string length in Codesys is 255 chars. It's not possible to cram 20,000 things in a string. If you need to send the data to another device, send the whole data[] array (as byte array, without doing anything to it) and extract the information on the other end. As each struct member has a fixed size (81 bytes, as per you declaration), this will be easy. To save some resources, consider declaring string lengths - e.g. if the max possible length for key is 10 chars, declare it key: STRING(10); and it will occupy 11 bytes instead of 81

Post by gurkan on OPCUA array max length? ^{CODESYS Forge talk (Post)}
We are using codesys 3.5.16.30 and we have a array with strings of length 5000. We are having issues subscribing to this variable from an OPCUA client. Is there any limit in the OPCUA Server in codesys for how long an array can be on the opcua server?

Post by martinlithlith on Relay board / relays for raspberry pi 3 b+ ^{CODESYS Forge talk (Post)}
hi! im planning a project on a raspberry with Codesys. For this I'll need a number of relays to control heating and fans, all a max of 24v and about 2a. How would i know if the board / relays i buy will be working with Codesys? Does every hat work or does it need a library/driver? is there a list of drivers/libraries created? as this is a hobby project all tips on a relay board or single boards that works with codesys and not to expensive are very welcome.

Post by rodberna on Library for arrays ^{CODESYS Forge talk (Post)}
Hi, I'm creating a program where I need to handle arrays, like: - Declare lenght variable arrays - [array(1..var) of "sometype"]. This is not possible in pure codesys, right? - Know array lenght, min, max, avg values in runtime - append/delete itens in an array - and so on Is there a library know for this in codesys. Is it possible to build our own libraries using some high level language like python or java script?

Post by dagsupport on CAA SerialCOM - hCom Reset max value 1023 ^{CODESYS Forge talk (Post)}
Hi everybody We are currently working on a project with an RS232 serial COM interface and using the CAA SerialCOM library. We have it working fine reading and writing data, although we have found an issue we cannot resolve and any suggestions would be helpful. We have noticed that after a while the RS232 stops working. We have tracked this down to the HANDLE hCom keeps increasing and when this reaches 1023 the COM returns an unknown error "5003". Is there a way to reset this hCom reference? Thanks Richard
