GE Fanuc 90-70's

GE Fanuc 90-70's

(OP)
I am trying to map a discrete input into a 16 bit register so I can pass the information off to EGD (8bit minimum registers). EGD does not work with bits (discrete inputs) and I don't want to convert it to an array because then my receiving device will have to use a whole register to store one bit of data.

Is there a way to map my I/O's into a register? From what I see, I can't unless I am using one of GE's PACSystems (which 90-70 is not). I am fairly new to these and what I am asking seems simple enough but can't seem to figure out how to do it or if it is possible.

Thanks in advance.

RE: GE Fanuc 90-70's

You can map any BOOL into any WORD with a 90-70. The easy way is to use the MOVE_BOOL function block. IN=%I3, Q=%R2, Length=4 will copy %I3,4,5&6 into the first 4 bits of %R2
For more versatility learn the Array_MOV Functions to put any bit anywhere.
To learn these functions select the one you are interested in, either within the 'Toolchest' or in Logic and Press F1 for detailed online help.

Thanks for the info. Believe this is exactly what I was looking for.
