Post by davelewis104 on J1939 SA ^{CODESYS Forge talk (Post)}
I am curious if there is a function block or function that will allow me to monitor the J1939 CANBus and pull out all of the SAs that are on a particular bus, without having to have them loaded in the J1939 manager?

Post by k2saki on CNC Override speed. SMC_Interpolator.dOverride is working ? ^{CODESYS Forge talk (Post)}
Hello. I have a question about override of moving speed. I am testing G-Code in Simulation mode. I set SMC_Interpolator.dOverride <--- 0.5, 1.0, 2.0 when Interpolator is working But SMC_Interpolator.dVel(speed) did not changed at all. Am I missing something to take effect ?

Post by mxj262 on FB having single input but initialized with Array ^{CODESYS Forge talk (Post)}
I am adding elements of an ARRAY using pointer to access each element inside a FOR loop and the FOR loop does not stop! What is the right way to use pointers in such case?? I have another loop that is not using pointer and it stops but the loop using pointer keep on adding. METHOD FB_Init: BOOL VAR_INPUT bInitRetains: BOOL; // TRUE: the retain variables are initialized (reset warm / reset cold) bInCopyCode: BOOL; // TRUE: the instance will be copied to the copy code afterward (online change) END_VAR VAR_IN_OUT // basically REFERENCE TO window_buffer: ARRAY [*] OF INT; // array of any size END_VAR THIS^.windowPtr := ADR(window_buffer[0]); THIS^.windowSize := UPPER_BOUND(window_buffer, 1) - LOWER_BOUND(window_buffer, 1) + 1; FUNCTION_BLOCK FB500 VAR_INPUT END_VAR VAR_OUTPUT END_VAR VAR windowPtr: POINTER TO INT; windowSize: DINT; currentIndex: UINT; element1:INT; element2:INT; i:INT; j:INT; sum:DINT:=0; END_VAR element1:=windowPtr[0]; // read the first element of the Array dynamic memorry element2:=windowPtr[1]; FOR i:=0 TO (TO_INT(windowSize-1)) BY 1 DO // this loop does not stop Sum:=sum + windowPtr[i]; END_FOR FOR j:=0 TO 5 BY 1 DO // this loop stops j:=j+1; END_FOR https://ibb.co/k3DhkZT

This worked for me. I had four identical PLC's. Three of them worked just fine with 255.255.255.255 as the broadcasting address but the 4th would not update the variables. Changed it to 192.168.x.255 and everything worked.

Post by hwopereis on SFC Action problems ^{CODESYS Forge talk (Post)}
Only logged in to agree with the above. So counter intuitive. Why does an associated action force the variable when the step it is associated to is not active? Makes no sense at all, is terrible to debug and costs a lot of time. Such as shame.

Hey Guys, could you give a explaination of how to change the g_udiMaxPacketSize from 6000 to 100000 and g_udiMaxPayloadSize from 4096 to 80000 ? When I go to the library the parameter is not editable. I would really appreciate it :) Kind Regards

Post by andrea199403 on Assigning Modbus addresses to a structure in a dynamic way ^{CODESYS Forge talk (Post)}
Hello everyone, I am new to this forum and I am also new to Codesys programming. My problem is this: I have a STRUCT of 64 bool and 30 real, this STRUCT is assigned in the programme 9 times. Now I need to communicate with an HMI via Modbus and I have defined the slave device and created the holding registers for communication. I would like to declare the first call of the STRUCT on the Modbus registers %QX2000.0 to %QX2007.7 for the booleans and on the registers %QW1004 to %QW1034 for the real registers. That said, I would like to change an index and set an offset of 100 bytes for the calls of the other 8 assignments, so that the result is: %QX2100.0 to %QX2107.7 for the booleans and on the %QW1104 to %QW1134 registers for the Real registers, etc. Is there a way to declare this? Thank you very much.

sorry I missed to say how to do this just update the runtime. (extract latest debian package out of the CODESYS package) but 8n this case an update all to the latest version including CODESYS is probably the easiest option now.
