Post by paulorb on STRUCT AT %MW1000 ^{CODESYS Forge talk (Post)}
Hi I am trying to use STRUCT to parse commands from Modbus/TCP, Modbus client will fill the bytes related to a specific command (type, parameters), then PLC (Codesys) will access the command parameters. A STRUCT will simplify a lot the process of parsing the data, so I don't need to parse byte per byte, address will be mapped to a struct and I can use it for parsing the data. From what I understood, the compiler does not allow me to specify the location of the struct for a %MW register. VAR_COMMAND AT %MW1002: structGenericModbusCommand; This will throw: Bad declaration, use '%ML' for 'structGenericModbusCommand' variable But If I change it to %ML, when you go online you see that it is actually allocating the struct in another memory address. When we go online, on GVL we can see: VAR_COMMAND. structGenericModbusCommand %ML1002 commandType COMMANDTYPE %MB8016 ... %MB8020 I am not specifying a pointer or a reference it is a struct type, why is it mapping to a %MW location (random one). How can I control where it is mapping to? I need a consistent way to map STRUCT to specific modbus address. Is it possible? Thanks, Paulo Note I am using a Codesys OEM: Schneider Machine Expert Logic Builder (M241)

Post by riccardo on Codesys SP19 patch 4 ^{CODESYS Forge talk (Post)}
Hallo everyone, I am working on new PLC of Weidmueller that uses Codesys SP19. I made the upgrade at the Patch 4 coming from patch 0. Unce made the upgrade everything is working well in the progect except the web visu user menagent. In the new version, when I perfom the login, I cannot use the keyboard of the device; the window where to digit the user name and password opens, the buttons "OK" and "Cancel" work but the system doesn't allow to put input from the device keybord, the mouse behaves as it is an image. If I active the virtual keypad or numpad it works otherwise nothing. I am wondering if it is a bug of the new package or if I must set something else. Thanks in advance, Riccardo.

Post by ton on How to create a stopwatch? ^{CODESYS Forge talk (Post)}
One i wrote this to measure elepse time When xMeasure is true is starts en when false it stops and time is messured. FUNCTION_BLOCK FB_ElapseTime VAR_INPUT xMeasure: BOOL; END_VAR VAR_OUTPUT xRisingEdge: BOOL; xFallingEdge: BOOL; tElapsed: TIME; ltElapsed: LTIME; ltPrev_Elapsed: LTIME; ltElapsedMax: LTIME; END_VAR VAR xLastValue: BOOL; LTIMEStart: LTIME; LTIMEEnd: LTIME; tonReset: TON:= (IN:= TRUE, PT:= TIME#30S0MS); END_VAR ------------------------------------------- xRisingEdge:= (xLastValue XOR xMeasure) AND xMeasure; xFallingEdge:= (xLastValue XOR xMeasure) AND NOT xMeasure; IF xRisingEdge THEN ltPrev_Elapsed:= ltElapsed; LTIMEStart:= LTIME(); END_IF IF xMeasure OR xFallingEdge THEN LTIMEEnd:= LTIME(); END_IF ltElapsed:= LTIMEEnd - LTIMEStart; ltElapsedMax:= MAX(ltElapsedMax, ltElapsed); tElapsed:= LTIME_TO_TIME(ltElapsed); xLastValue:= xMeasure; tonReset(); IF tonReset.Q THEN tonReset.IN:= FALSE; ltElapsedMax:= LTIME#0NS; END_IF Meaby this will help.
