I am trying to program an AUTO-MANUAL switch on a c more micro touch screen. When i build the switch in the tag name database it only allows me to put one discrete (GX0) for the AUTO. I need to close GX1 when i switch to manual. ??? i.e. AUTO-off-MANUAL motor control. Thanks in advance David

    So instead of only two states - Auto and Manual - you need three states - Auto, Off and Manual. I don't see a three state switch. Unless others come up with more involved objects you may have to graduate to the C-More.

    Why don't you just use the two states of GX0 to differentiate between the two modes of operation. I.E...in manual mode, GX0=OFF, and in auto mode GX0=ON?

    The radio button will work for H-O-A stuff. Not as pretty but works.

    I didn't see a selection for radio button in the CMore Micro. How is that done?

    One thing I have done in the past is use an integer register in the PLC to hold the Auto-Off-Manual state. You would have to edit the PLC program to include a truth table or edit your existing logic to directly use the integer register. In the HMI, you setup three buttons that simply write a pre-programmed value to the register. Usually in my setups, 0=Off, 1=Manual, 2=Auto. The three buttons on the HMI would mimic a radio button type setup. The main benefit is being able to program almost any HMI with this method (i.e. the HMI doesn't have to have a special three-position or radio button object.)

    I don't know if this will help you, but once or twice I 've created a radio button with recipe buttons. Your recipe just sets one bit as ON, and the other bit as OFF. The Manual would be opposite of Auto, and the Off Button would set them both OFF. The only problem is indicating which is the active state, so you would need to have indicator lights sitting on top of the recipe buttons. Kind of a long way around, but it will work.
