Direct Data Exchange with Pico/GFX (Polled
I/O Connection)
The DeviceNet master can exchange the following data with the
Pico/GFX via the direct cyclic data exchange:
• Write operation
– Setting or /resetting of the Pico/GFX inputs (R1 to R16)
– Determination of the RUN/STOP mode.
• Read operation
– Scanning the output states of the Pico/GFX (S1 to S8)
– Scanning the mode of the Pico/GFX.
In order to transfer data between the slave 1760-DNET and a
DeviceNet master control, you must map the respective cyclic data to
the respective slave configuration.
TIP
The terms “input data” and “output data” are used
relative to the point of view of the DeviceNet master.
TIP
The interconnection to the DeviceNet controls from
Allen Bradley is implemented using an assignment
table in the RSNetWorx software tool.
