I/O Mapping an I/OBus Network with Concept

Supporting an I/O Map for an I/OBus Network

Introduction	Three Processor Adapters have an I/OBus communication port that enables them
	to control and communicate with other network slave I/O:
	λ 171 CCS 760 00
	λ 171 CCC 760 10
	λ 171 CCC 960 20
	λ 171 CCC 960 30
	If you are using I/OBus to control network I/O, you need to write an I/O Map in your
	configuration. This section describes the configuration parameters required to
	support an I/O Map for I/OBus.
I/O Map
	Be sure that you have reserved enough words for I/O mapping to support your I/O
Reserved Words	Bus network. The default setting is 144 words. To estimate the number of words
	you require, allow:

λ16 words for overhead

λ10 words/module on the network (including both the local and the network I/O)

Allot sufficient memory to completely I/O Map your network, while preserving as much user memory as possible for your application program.

Number of	Be sure that the number of segments is set to 2. If you have changed this setting to
Segments	1, you will not be able to support an I/OBus network.
Next Step
	Once you are sure that your Configuration Overview parameters are set properly,
	you can access an I/O Map screen for an I/OBus network.
