Technical support / RS485 Output

« on: January 10, 2007, 10:27:18 PM »

Is there any way to use the RS485 as a simple output. All I need to do is to turn a 50mA LED on with 1.85V across it whenever a counter = 0.

I have all other 16 inputs on my T44H-npn in use and I'm hoping that I wont have to either upgrade to a bigger board or add more hardware.

I'm assuming that this can be done and should be easy, considering this is a communication port, but I'm having trouble understanding how to go about this.

Thank you, it worked!

But now why would it have worked as a .PE3 file and not as a .PC3 file? Should the original file not have worked in the first place? I guess I dont really need to know, now that i know how to avoid the error.

Thanks again,
Dario

Technical support / Duplicate Coil?

I'm trying to run this logic on an H-Series PLC (T22H-npn). I've simplified my logic to just 2 components: 2 inputs and 1 output. I'm getting a message that says:
_______________________________
Failed at Circuit#3
Duplicate Coil:Output"MOut1"
is already energized
_______________________________

Here's what my circuit looks like:
______________________________________________________________
| Contact MOut1
|-------i||------------------------------[Latch]
|
| MSW MOut1
|-------i||------------------------------[Clear]
|
| Reset MOut1
|-------i||------------------------------[Latch]
|_____________________________________________________________

The same logic worked on an E10-npn+ PLC, so I'm not sure why I'm getting this problem. Am I missing something?

Thanks in advance for your help,
Dario
