PeerĆtoĆPeer Master Configuration
When you configure a channel as a master on a peer-to-peer
communication channel, you must enter the following parameters:
Parameter Description
Master number identifies the master for communication with the slaves. Each peerĆtoĆpeer
communication channel can have one master only. The master number and all
slave numbers must be unique and selected from numbers 81 through 89.
Slave numbers identify the slaves that communicate with the master. Each master can
communicate with up to 6 slaves. The slave number must be unique and
selected from numbers 81 through 89.
Input files identify the files that receive data from each slave. You must specify an input
file for each slave in the input image section of the data table. If you do not
make a selection, the file defaults to input file 1. The files also must be large
enough to store the data from each slave's output file. If the file is not large
enough, the processor declares a minor fault.
Output files identify the files that send data to each slave. You must specify an output file
for each slave in the output image section of the data table. If you do not make
a selection, the file defaults to output file 1.
LIST displays the size of the input and output files. For example,
I1:0
→
19 shows that input file 1 contains 20 octal words. You can create
a larger file by entering the last word desired in the file when prompted for
the file number in LIST. By entering I1:50 for the input file, the system
will automatically increase input file 1 to 50 octal words.

PeerĆtoĆPeer Slave Configuration
When you configure a channel as a slave on a peer-to-peer communication
channel, you must enter the following parameters:
Parameter Description
Slave number identifies the slave that communicates with the master. The slave number must
be unique and selected from numbers 81 through 89.
Master number identifies the master on the channel. The master number and all slave
numbers must be unique and selected from numbers 81 through 89.
Input file identifies the file that receives data from the master. This file must be in the
input image section of the data table. If you do not make a selection, the file
defaults to input file 1. This file must be large enough to store the data from the
master's output file. Otherwise the processor sets the peerĆtoĆpeer minor fault
bit.
Output file identifies the file that sends data to the master. This file must be in the output
image section of the data table. If you do not make a selection, the file defaults
to output file 1.
