Post by pethun on Upgrade from codesys 3.5.19 to 3.5.20 ^{CODESYS Forge} ^talk ^(Post)
Hi We upgraded our ptoject from 3.5.19 to 3.5.20 but we get an error message in the latest version. We made our own trend function and its related to this we get error message: Trend_Menu Device: PLC Logic: Application: C0032: Cannot convert type 'RTS_SYSTIMEDATE(systimertc, 3.5.20.0 (system))' to type 'RTS_SYSTIMEDATE(systimertc, 3.5.17.0 (system))' The variables are defined as follow: start : SysTimeRtc.SYSTIMEDATE; end : SysTimeRtc.SYSTIMEDATE; The code that creates the error is the variable start and end IF xAssign THEN xAssign := FALSE; xPanEnable := FALSE; xZoomEnable := FALSE; drs.liFrom := VisuTrendStorageAccess.TrendStorageConvertToTimestamp(start, 0 (us)); drs.liTo := VisuTrendStorageAccess.TrendStorageConvertToTimestamp(end, 0 (us)); drs.m_itfDateRangeSelectorClient.SetCurrentRange(drs.liFrom, drs.liTo); END_IF I cant understand really what the error message means and what can be the cause of the error? It compiles fine in dthe older codesys 3.5.19. If anyone has some experience of this please help us out? We must upgrade due to the new licenses. Thanks

Post by mubeta on STRUCT AT %MW1000 ^{CODESYS Forge} ^talk ^(Post)
This is normal and correct since in CoDeSys static addressing of variables uses the IEC method. A LONG tag has the size of 8 bytes, so %ML0 coincides with %MB0 ... %MB7; %ML1000 with %MB8000 ... %MB8007. (Similar reason for word and other formats). Also the reason the compiler won't let you map the structure to a %MW depends on the fact that the individual base elements are manipulated to 64 bits regardless of the smaller size. That said, it makes me strange that you cannot write a parser without making use of static memory allocation.

Post by garrian on How to write multiple coils (Modbus FC15) ^{CODESYS Forge} ^talk ^(Post)
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.

Post by esave on Softmotion Axis Controll ^{CODESYS Forge} ^talk ^(Post)
Hello everybody I have two of these EtherCat CiA402 stepper driver from Leadshine: https://www.leadshine.com/product-detail/EM3E-556E.html I want to controll them. I already have implemented them in Codesys with Softmotion. I see the position, the velocity and the status word so I can read everything. See picture 1. But when I want to write something like MC_Power or MC_MoveAbsolut with the SM3_Basic library it wont work and with the MC_Reset POU it shows: "SMC_R_DRIVE_DOESNT_ANSWER". See picture 2. Can somebody help me? Thanks a lot esave

Post by uluking on CodeSys2.3 Modbus 64-Bit Double Read Problem ^{CODESYS Forge} ^talk ^(Post)
Hi everyone, I would appreciate your help with a problem I've been working on for a few days but haven't been able to resolve. I am reading data from a Siemens PAC3220 energy analyzer using Modbus with Wago-8202. However, the device's energy indices are given as doubles. Since a double variable is 64-bit, it is not possible to read it directly. I have been struggling for days, I have written many conversion functions but I have not been able to get results. I would appreciate your help. I read 4 word variables and processed them. I am converting them according to IEEE-754, but I can't seem to read the correct data. I would appreciate your help.

Post by macros8 on Alarm Management - latched variable represented as Text list ^{CODESYS Forge} ^talk ^(Post)
Hi, I haven´t noticed you put the comment here. I thing it´s a bit different. What I want is to have detail errors of technology in data type e.g. INT. This variable I would latch to the corresponding error msg but I would like to get it convert to text from the text list and not keep it in INT form. Example. Main error Valve Error: SubErrors 1 - Both sensors 2 - Not retracted in time 3 - Not pulled out in time In HMI Main error + latch SubErrors => "Valve Error: Both sensors" The benefit is that text lists are part of translation and can be easily manipulated. I know I can create whole string msg in PLC but then, it lose advantage of Alarm management. Thanks. M.

Post by hanoues on setting date and time on CPX-E ^{CODESYS Forge} ^talk ^(Post)
Hello, Can anybody here tell me how to modify the time and date on my CPX-E? I used the code I found on CODESYS online help, but it doesn't work. What am I missing? FUNCTION current_date_time : STRING VAR stUTC_Timestamp : SysTime; //utc time // ULINT#1528280694913 stLocal_TimeStamp : SysTime; //local time but is in general equal // ULINT#1528280694913 stdNow : SysTimeDate; //local time in an object to access each number (day, month...) dtNow : DATE_AND_TIME;//DT#2018-6-6-10:24:54 todNow : TIME_OF_DAY; // TOD#10:24:54.913 datNow : DATE; // D#2018-6-6 END_VAR SysTimeRtcHighResGet(stUTC_Timestamp); // ULINT#1528273494913 SysTimeRtcConvertHighResToLocal(stUTC_Timestamp, stdNow); //convert UTC ULINT to Local SysTime // stdNow.wYear = UINT#2018 // stdNow.wMonth = UINT#6 // stdNowy.wDay = UINT#6 // stdNow.wHour = UINT#10 // stdNow.wMinute = UINT#24 // stdNow.wSecond = UINT#54 // stdNow.wMilliseconds = UINT#913 // stdNow.wDayOfWeek = UINT#3 // stdNow.wYday = UINT#157 SysTimeRtcConvertDateToHighRes(stdNow, stLocal_TimeStamp); // ULINT#1528280694913 dtNow := TO_DT(stLocal_TimeStamp / 1000 ( ms )); // DT#2018-6-6-10:24:54 todNow := TO_TOD(stLocal_TimeStamp MOD TO_ULINT(T#1D)); // TOD#10:24:54.913 datNow := TO_DATE(dtNow); // D#2018-6-6 (convert to appropriate string) current_date_time := concat('$N[', TO_STRING(dtNow)); current_date_time:= concat(current_date_time,'.'); current_date_time:= concat(current_date_time, TO_STRING(stdNow.wMilliseconds)); current_date_time:= concat(current_date_time,'] - '); RETURN;
