Post by user3000 on Can't find an Extended Pulse Timer (TP and LTP) ^{CODESYS Forge talk (Post)}
I came up with an FBD that seems to be working, although it may not be a true Retriggerable Pulse timer. There may be some delay associated with the two MOVE functions and ADD function I incorporated. I'd be interested if anyone is able to come up with something cleaner. I am surprised that this is not a built-in function block of the CodeSYS library. This is a common feature of multi-function timer relays. I also attached a page from the cut sheet of a Schneider relay that shows 10 timing functions. Looks like the CodeSYS library has built-in function blocks for only 3 of the 10.

Post by aniket-b on Multiple function blocks are not executing at the same time in ladder logic ^{CODESYS Forge talk (Post)}
I have two ethernet Ip drives and created Function Blocks for different motions tasks. I am using same FB for both the drives. When I try to execute the relative move start command on FB for both the drives it is not working. However, if I add 1ms second delay between the execution of each drive it is working. Also when I change the rung order it is working for the first drive in the rung. what could be the wrong here?

Post by tk096 on Motion FB Error ^{CODESYS Forge talk (Post)}
Hi, Softmotion Robotics does not support tracking in/out to dynamic coordinate systems with relative movements. Is MC_MoveLinearAbsolute an option? See SMC_RELATIVE_MOVEMENT_TRACKING_CS in https://content.helpme-codesys.com/en/libs/SM3_Error/Current/SM3_Error/SMC_ERROR.html Concerning the other error: Do you use any motion function blocks of SM3_Basic to move a single axis of the robot in your application?

Post by tk096 on gear over gear (2 masters,1 slave) - how to do it? ^{CODESYS Forge talk (Post)}
Hi, you could calculate the position/dynamics of the slave axis yourself and use one of the function blocks SMC_FollowPosition/SMC_FollowSetValues to move the slave axis. https://content.helpme-codesys.com/en/libs/SM3_Basic/Current/SM3_Basic/POUs/Movement/Direct/SMC_FollowPosition.html https://content.helpme-codesys.com/en/libs/SM3_Basic/Current/SM3_Basic/POUs/Movement/Direct/SMC_FollowSetValues.html

Post by timvh on Stack overflow with really simple function ^{CODESYS Forge talk (Post)}
You have declared the function block in a function and call the instance also from a function. This is not correct, because a function is initialised with every call. The http client function block should be declared as Global Variable if you want to cal it from a Function, but probably it is better to declare it in a Program and also call the instance of the http function block from the same Program.... The variables of a Program are not initialised with each call.
