Switch LAMP latch
MarinusS posted a topic in MitsubishiHello I'm new with GT Designer 3, I'm writing code for a GOT2107 HMI. I have a few buttons that when you press it, the LED on the switch comes on, and when depressing the switch the LED goes off. That's good, but how do I create a latch, that when the switch is pressed and depressed, the LED will stay on. and only go off after the next press and depress? The attached image is my working switch button. Regards Marinus
MarinusS posted a topic in MitsubishiHello I'm quite new with GT Designer 3. I'm writing code for the GOT2107 HMI. I have a few push buttons that works fine when pressed the switch lights up as you touch the switch. But now I want a latching switch. Every time the switch is pressed the light on the switch should alternate. How do I get a switch's lamp to stay on after pressing it? Thank you Marinus

GX IEC Developer to GXWorks2
newbee posted a topic in MitsubishiHi all, I am a newbee with GX works2 and I got stuck in the change of developer software. Hope anyone can help me to find a easy way to solve this. I got a program in GX IEC Developer 7.04 where I have Latch(1) on all D register I am using. PARAMETER - PLC DEVICE - Data register is 0-13312 and SystemVariable are from 3000-13311. I have not find a way in GXWorks 2 to allow the same. I figure out I need to change variable type in FB to VAR_RETAIN but how do I solve this for Global variable? Do I have do give all the variable fix addresses?

Luigi802 posted a topic in Allen Bradley / Rockwell AutomationOK so this is driving me nuts, because I had this whole program just about finished and working fine, until I deleted it Now I don't remember how I did it, if could just get past step 2 in the attached "Scope" I'd be fine and could do the rest myself, I'm kindof a beginner to ladder logic and I'm using RSLogix 5000 SCOPE.docx
Modicon to Control Logix conversion
ScottyH posted a topic in Allen Bradley / Rockwell AutomationMy project is converting a Quatum Modicon to a Control Logix. We took the Modicon Logic ran it thru a Rockwell converter and created the Control Logix Logic. This was nothing complicated but a large file. In Modicon you have a Memory retentive bit -- (M). This converted to a Latch (OTL) in the Control Logix, we decided to place a coil OTE in Parallel with the Latch so we could unlatch on the rung going false. The memory retentive coil is there to hold memory on power cycle if it ever happened. So.... The question is Unlatch below The latch, or above Consider left a representive of converted logic in the AB. Logic a bit more complicated. A B C lL. U --||--|||--|/|--(OTL)--(OTE). L |. . --||-----|.
