Internet PLC Forum

I previously had asked about mouse wheel scrolling in TRI-PLC programming software. It is very convenient to scroll up and down in the source code with the mouse wheel.

I have discovered a solution in a small software package that lets you assign the mouse wheel control by application. The website is http://www.ardamax.com/mwc/ it is free to try for 30 days $14.95 to buy.

The control needs to be set to  the Javaw.exe file in your Java directory. I allows you to define control action and assignment. I'm sure there are other programs to do this, but this one worked for me.

One less development task for TRI-PLC.

Cheers !

Good information. I saw the smiulator showing the desired move and noticed the direction bit not changing. I wanted to make sure all was working correctly since it looked like it was not on the pin level.

if I print out my Custom functions I get printouts with many blank pages along with the custom functions. I would say about 75% blank pages having just a number at the top and the name of a custom function.
Any idea what is going on or is this normal ?

I have a need to load a stepmove distance and then during the execution of that move and prior to completion, to stop the motor and hold position.

I then will continue the move to the original completion point. I would call this a "feed hold" type of function. It looks like I can create this function with the stepcount function and some code. I would like to simply execute a STEPSPEED 1,0 to cause the stepper pulse stream to stop until I give a new STEPSPEED command to resume the move, but it faults out.

Any elegant solutions come to mind? Suggestions of best way to do this?

I have the MD420 HMI. In my application larger characters would be easier for operator to read. Is there a command which changes the font size for the LCD controller to double size? I would like 2 rows of larger characters.
Thanks

Ah you point out my poor use of words. I am using regular outputs as SINKING outputs. My mistake. The other side of the solenoid coil is tied to +24vdc on same PS as PLC. I will try to see if states are same with online monitor, but hard to catch.

Rare output means when the machine is coming to the end of the cycle it will infrequently  and without pattern (once in 40 times as an example with no setting changes) cause the output which have state changed through a toggleio in CuFunction to change state and stay in the changed state. The only pattern which seems more common is that the bit changes from low to high. It has done the opposite, but not often.

The only section of code to change solenoid bit state is as follows:

'Toggles i/o 9 to change clamp state. for supply spool clamp 1. A low output=clamped so if have bad solenoid or bad wire or loose power , part stays clamped.

'SOL_SU1_CLMP IS THE SOLENOID

TOGGLEIO SOLSU1_CLP         'CHANGE OUTPUT BIT FROM CURRENT SETTING EACH TIME FOOT SWITCH  IS PRESSED.

IF TESTIO (SOLSU1_CLP) = 0 THEN   'Check to see SOLSI1_CLP current state after toggle i/o bit

   setio Su1clamped      'i/o bit is OFF to SOLSU1_CLP, clamp flag relay set indicating SU1 clamped.
ELSE
   CLRIO Su1clamped      'i/o bit is ON to SOLSU1_CLP, clamp flag relay cleared indcating SU1 not clamped.
ENDIF

The only way the above section of code is executed is by the pressing of a manual foot switch. The machine has four of these clamps and all have the same problem. All are on adjacent outputs.

I swapped the output IC as a test, same results. Added static brushes to ground product same results.

Ideas?

Thanks. I am sure others will appreciate this also.
