Hello, I am using a Variable: Range of Images to display the output status of a heat controller. The output status is determined by the LEDs of the heat controller display.The heat controller provides the LED statuses in a byte which I convert to bits using the Vector Number to Bits to view the bit status of the 2 relay outputs and the alarm. Then I convert those three bits back to a number using Vector Bits to Number. The first bit is the Alarm the second bit is Output 2 and the third bit is Output 1. So for the Variable: Range of Images I have the alarm image set for the constant value from 1 to 1. From 2 to 2 I have an image to represent cooling. From 3 to 3 I have an image to represent an over-temp state (alarm and cooling). From 4 to 4 I have an image to represent heating. From 5 to 5 I have an image to represent under-temp (alarm and heating). The MI output from the Vector Bits to Number is exactly as I would expect it to be and the Variable: Range of Images displays the correct image but instead of replacing the image previously displayed, the new status image is superimposed on top of the other image. How can I address this superimposition?
Volume is simple to calculate. I will likely include the flow rate on the HMI some place for the operator, but until I have it worked out just right I don't want to bother.
OK. Ausman UniGuru.
But my problem is from 2014, still waiting reply from Unitronics and there are many people with the same problem.
We have more than 50 of your PLC's working well but you need to work on your tech support.
Firstly thank you for your valuable inputs and replies to posts on the Form. Much appreciated.
So I’m using the linearize block but am not sure which values should go where.
And also not sure with what you mean by “time base”?
To be specific I need to increase temperature from ambient to 1000C over 3hours.
So the double image issue with a binary image is kind of solved by using -p- and -n- to refresh HMI when that output is on/off. For now I just use a binary image/switch to to show red off and green on instead of the rotating fan. I know I am a quitter, but I have another fish to fry and I don't want to stop the machine during production time.
thank you for all the help!
