I/O Mapping an I/OBus Network with Concept

870 USE 101 00 V.2.2
Supporting an I/O Map for an I/OBus Network
Introduction
The 171 CCS 760 00 Processor Adapter has an I/OBus communication port that
enables it to control and communicate with other network slave I/O.
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.
Note:
Concept 2.1 does not support the 171 CCC 760 10 Processor Adapter.
This Processor Adapter will be supported in Concept 2.2.
I/O Map
Reserved Words
Make sure that you have reserved enough words for I/O mapping to support your
I/OBus network. The default setting is 144 words. To estimate the number of
words you require, allow:
16 words for overhead
10 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
Segments
Make sure that the number of segments is set to 2, the default setting. If you have
changed this setting to 1, you will not be able to support an I/OBus network.
Next Step
Once you have made sure that your Configuration Overview parameters are set
properly, you can access an I/O Map screen for an I/OBus network.
