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 base unit with gateway interconnection and the

DeviceNet programmable controller.

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

unacknowledged) is used to transfer 2 bytes of diagnostic

data from the control relay to the DeviceNet programmable

controller.

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

to function relay parameters in the control relay. This type of

connection set-up also supports the configuration, diagnostics

and management services of the control relay.

• DeviceNet Communication adapter profile (device type 12),

which has been expanded by requests

• 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
