The program needs to pass different values from UDF to another UDF depending on the settings that have been chosen with the knob. The parameters that I'm passing between the UDF's are time values in seconds and count values in positive numbers ranging from 5 to 10. The time values are passed with no problems what so ever, but the count values are generated in the first UDF but no read by the second UDF. I have mapped the values to differen VM addresses without any succsess. I'm not getting the problem. I was thinking, maybe the target UDF cannot accept values generated from two different UDF's? With a hope of help, Ingvar! ------------------------------------------------------------------------------------------ Split from Input counter value Dword to Function Block with word type parameter.

UDFs called Chooser and another called Counter should pass their values to all of the UDF's on the right, but I have only for testing purpose connected one of the UDF on the right, called 551.

ingostar Posts: 12 Rating: (0)	Yes, I probably should have been more specific, the values are transferred but not picked up by the up counter. But the timer seemes to pick up it's value. But the up counter doesn't read it's value.

If you simulate it, you will see that changing between program 1 and 2 really changes the time it takes for the 551 UDF to turn on it's outputs. From 120 sec in program 1 to 5 sec in program 2. But here is the thing, both of these programs don't count up to its value but stop after 1 round. The UDF should count how many times it should turn on and of it's outputs but it only turns both outputs on 1 times. This is highly inconsistant to the simulation of the 551 UDF. And in my previous tests, if I hardcode the values into the 551 UDF it works perfectly.

That happens. You have not written that the following UDF (551) does not work as you imagine. And the fast times to control your UDFs, I can not. For this I had to know what you thought when creating. There is nothing documented in the UDF's.

This program is a work in progress and I haven't made many comment into the UDF's and blocks. But here is an explaination of the UDF's on the right. All UDF's on the right work the same. 551 UDF: This UDF accepts a start and a stop value coming in from the left. It has three timers and two counters.The first timer turns on an output called ON Cycle, the second timer turns on the output called OFF Cycle. When both timers have flipped back and forth the required amount of counts which is a value stored in ON Counter and OFF Counter counter blocks, it passes the signal to a pause timer which only runs once. After that, the signal is passed to the Cycle finished output and this UDF has finished it's purpose. In my effort to be able to control the timers values and the counters values, I made an external UDF that passes it's values from an analog MUX block depending on the state of the input. In order to simplify my design, I chose to have two UDF's. One sends the time value and the other sends the counter value. It turns out that these values need to be in two UDF since there is a restriction on how many parameters one can have in one UDF. So the UDFs with the time and counter value work and the values are passed to the work UDF, but here is where the program starts to fail. The time value is picked up by the timer block inside the UDF but the up counter block inside the receiving UDF doesn't pick up it's value. No matter how I try to tweak all values and processes, the 551 UDF just doesn't pick up it's ON/OFF count value.

But for my better understanding: You have the circuit of the UDF first created as a normal program and then tested this. Then you have copied all the necessary blocks and inserted into the UDF. Right? If so, then this may be the problem. Already happened to me with several UDF, that these did not work then as they should. It has in my case then only a proper function, if I rebuilt the circuit in the UDF after the template and did not simply copied the blocks.

ingostar Posts: 12 Rating: (0)	Hi, thank you for the suggestion. I will try to rebuild the UDF without copying it. I will let you know what comes out of it.
