Digital Output reading in LABVIEW

[omerdf]

Hi,

im using modbus fundumentals example in order to read and write into delta plc registers ( by using a matching ladder diagram)

i have succeeded to read input values from its register .

i would like to know how i could read digital output values.

thanks

omerdf,

So to clarify, you are able to read the inputs to your PLC by reading the delta registers, but you would also like to be able to read the digital outputs of the PLC with the same method (modbus)?  Or, are you instead interested in using a Digital I/O device, such as NI's multifunction DAQ devices, to read the digital output values of the PLC.  Also, what is the make and model of the PLC you are using?

hello ,

exactly , i would like to read the digital outputs with the same method (using modbus) if its possible ofcourse.

thanks
