Converting Bool to Float in Studio5000

mahmoud shahien · Apr 1, 2018

Dear Experts,

I need to send Boolean array from PLC (1769-L19ER) to device which recieve only float data.
So, How can I convert Bool array to Float array in Studio5000.
Thanks.

Use a For/Next loop with each itiration being:

Float_Array[x] = Boolean_Array[x]

If it doesn't like the math then just use two rungs:

XIC Boolean_Array[x] MOV 1.0 Float_Array[x]

XIO Boolean_Array[x]. MOV 0.0 Float_Array[x]

Thanks Bernie for your reply.
I checked MOV & COP before but not accepted.

Why?

You could try moving a hard coded number when the bit is on and then another move when the bit is off.

That's a correct response because MOV and COP don't accept booleans as parameters.

As Bernie pointed, you can move 1.0 or 0.0 to the float array according to the boolean value you are evaluating.

XIO Boolean_Array[x]. MOV 0.0 Float_Array[x]

Code:

 Boolean_Array[x]   |-----MOV----------|
------| |-----------|             1.0  |
                    |   Float_Array[x] |
                    |------------------|

If the float array is reset before entering to the FOR loop, you'd not need to evaluate the false condition of the boolean value.
