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
