The INTERBUS ID Code

Introduction	The ID cycle is part of the INTERBUS network’s initialization process. After
	determining the length of its own data during network initialization, every network
	device reports its functionality and byte length in the two-byte ID code. The
	INTERBUS ID code is a 16-bit word that describes the data type, data length and
	module type (digital/analog, input/output/mixed) of network devices.
The Low and
The Low and	Data type is transmitted in the ID code’s low byte; data length and message
High Bytes	information are reported in the high byte:

1data type (03h, 33h)

2data length (0 to 16 words)

3messages (for management functions)

Data Type	The INTERBUS NIM recognizes one of two possible data types:

	Data Type	Signal Direction	Signal Type

	03h	input/output	digital

	33h	input/output	analog or mixed
