Important: ` - Backtick - ASCII 96 ' - Apostrophe or Single Quote - ASCII 39 In the online help for some reason it renders ’ ...

Post by serwis on Dynamic target position tracking ^{CODESYS Forge talk (Post)}
Hello, I am trying to control a servo drive and dynamically set its position. I control the drive via EtherCAT with a cycle time of 500us. I use the MC_MoveAbsolute block for this. The problem is that when using a PID controller, I generate the positions I want the drive to move to on an ongoing basis, and I would like the position to be set immediately. The MC_MoveAbsolute block must receive a rising edge to execute, and I would like the movement to be performed without waiting for this edge. I have created a function that generates a rising edge every 1 ms, but I am unable to change this time to 500 µs because the TON function does not support times shorter than 1 ms. Below is the code to call the rising edge: IF Exe = TRUE THEN delay1(IN:=TRUE, PT:=T#1MS); IF delay1.Q = TRUE THEN Exe := FALSE; delay1(IN:=FALSE); END_IF END_IF IF Exe = FALSE THEN delay(IN:=TRUE, PT:=T#1MS); IF delay.Q = TRUE THEN Exe := TRUE; delay(IN:=FALSE); END_IF END_IF END_IF Here is the code for calling the MC_MoveAbsolute function: MoveDegree( Axis:= Tilt, Execute:= Exe, Position:= position_target - (base_angle_real * feedforward_turn), Velocity:= vel, Acceleration:= acc, Deceleration:= dec, Jerk:= jerk, Direction:= MC_DIRECTION.shortest, BufferMode:= MC_BUFFER_MODE.Aborting, Done=> , Busy=> , Active=> , CommandAborted=> , Error=> , ErrorID=> ); I realize that there are probably better methods for performing this type of task. How can I implement motion with a dynamically changing setpoint? THANKS

Post by rmarco on Generic Variables and FDB ^{CODESYS Forge talk (Post)}
Hello everyone, I am running into a highly frustrating issue in the FBD editor regarding a Function Block with generic constants (VAR_GENERIC CONSTANT). I created a FB using ST, with a generic var, useful for having a variable sized array, as follows: FUNCTION_BLOCK Coil VAR_GENERIC CONSTANT maxEvents: USINT := 5; END_VAR VAR events: ARRAY[0..maxEvents-1] OF IEvent; END_VAR These FBs have also several methods. I declare them as follows in code: VAR coil1: CDL.Coil<(maxEvents:=1)>; END_VAR and when using them in ST, I have no problems. However, when trying to use them in FDB, I do not know how to do that, as some strange misalignment happens. Here's what happens: When I add the block to my FBD canvas and assign coil1 as the instance name, the compiler throws this error: 'coil1' is not an instance of 'CDL.Coil<(maxEvents:=1)>'. Same occurs when I try to instantiate blocks such as 'coil1.turnOn' or similar. Here is what I have already tried, none of which worked: - Deleting the <(maxEvents:=1)> parameter from the text inside the FBD box. - Deleting the block entirely, dropping an "Empty Box", and typing coil1 above it to let the IDE auto-complete and format the block. - Running a full "Clean All" and rebuilding the code. I am aware that I could bypass the graphical editor by calling it in Structured Text. However, I need to keep this logic compatible to FBD. Has anyone encountered this specific FBD parsing bug with generic variables? Thanks in advance for any insights. Best regards, Marco
