Hi! I just started with PLC programming. I am trying to get the time between a output signal and a input signal. The problem is that the time is ~200 ms but when i measure it with this code: TONR(Timer1); IF PosFeedback <= PosFeedback_Min & not Timer1.Reset THEN Timer1.TimerEnable := 0; FullCloseDeltaTime[1] := Timer1.ACC; Timer1.Reset := 1; END_IF; IF (move & not Move_LastScan) THEN //Start timer Timer1.TimerEnable := 1; Timer1.Reset := 0; END_IF; Move_LastScan := move; i only get even values in intervalls of 50 ms like 150, 200 and 250 ms. I have changed the real time sample rate to 11 ms so i don't understand why i don't get a more exact result. And i can see in my trend that the time isn't exactly 150, 200 or 250 each time. I i tried and time my own click on a button and i see the problem is the timer, i only get values in an interval of 50 ms. Is there a way to make the timer more exact?

Hello all, I was asked to check if there is a PID real - time software which automatically calculates PID loops parameters and update the PLC registers or HMI ( by OPC server etc.) when the process is working and "breathing". REAL-TIME. Not PID simulator or PID tuner based on measured data, but a software that will calculate and update the PID parameters in real time while maintaning several PID loops simultaneously. Are there any suggestions? Thank you, Olesia

Have looked on this forum and found NO hint of a solution. I hope someone can provide me with a starting point. I have a Allen Bradley Micro830 & Connected Component Workbench that I use to SMS text message out the value of an Analog sensor. The value is a real number data type so it holds a number like this 123.32659+e. All I want to do is to "Truncate" so that the value ends up being like this 123.32 this would then be what sms receiver would see as the value. Thanks

In my present project, I have to interface an energy meter that has its kWh count in 64 bit Double format. Now that Vijeo citect hasn't a facility to create tags of the "double' type I am looking for a work-around to this problem. Thanks for any help/advise in this matter

Turning inches traveled per pulse (a real number) to inches per minute
487mcgill posted a topic in Allen Bradley / Rockwell Automation
I am currently trying to get my program to take distance traveled per pulse, which is based off of the diameter, and convert it into IPM. I am using RS Logic 5000 software. If anyone could help me get over this hump I would really appreciate it!
