Analog inputs and outputs use the values and equations listed in Table 4-13 to define the voltage ranges and the corresponding digital values (assuming N is the number of bits of resolution available at the DeviceNet interface). Unsigned binary is used to represent the 0 to +10 V range.

Note: The conversion is assumed to be linear across the range (a one-bit change always corresponds to the same voltage change in the AI/AO within the hardware capabilities of the device).

DEVICENET INTERFACE CHARACTERISTICS

The device uses rotary switches to set the MAC ID. This allows you to visually verify the MAC ID setting, and simplifies the configuration of replacement parts in field repair situations.

The device is delivered with the baud rate set to 500 KBd which does not change if the device is power-cycled.

The device supports the DeviceNet Duplicate MAC ID Check protocol.

The device uses DeviceNet’s Group 2 I/O Poll Command message (and the associated Group 1 I/O Poll Response message) to transfer low-level I/O data between the device (slave) and the master.
