Pico and Pico GFX-70 Programmable Controllers 13

DeviceNet Communications Module

The Pico DeviceNet module, 1760-DNET, allows you to have a Pico

controller operate as a slave device on the DeviceNet network.

The DeviceNet module connects to the Pico controller like an

expansion I/O module. It can be used with the Pico 18- and 20-point

controllers and the Pico GFX-70 controller. 24V dc power must be

provided to the device.

The DeviceNet module is equipped with Network and Module status

LEDs. It uses the following communication profile.

• Predefined master/slave communication settings

– The I/O polling connection is used for the transfer of 3 bytes

of input data (R1 to R16) and 3 bytes of output data (S1 to S8)

between the Pico controller and the DeviceNet master.

– The I/O Change of State/Cyclic connection (acknowledged,

unacknowledged) is used to transfer 2 bytes of diagnostic

data from the Pico controller to the DeviceNet master.

– The explicit connection set-up is used for read/write access to

function relay parameters in the Pico controller. This type of

connection set-up also supports the configuration, diagnostics

and management services.

• DeviceNet Communication adapter profile (device type 12)

• Group 2 server

• UCMM-capable device

• Dynamic set-up of explicit and I/O connections are possible

• Device Heartbeat Message

• Device Shutdown Message

• Offline communication settings
