This section explains how I/O communication is performed with the master node.
(a) When starting I/O communication by I/O Communication Request (Y11)
1) Set the following:
•
Set parameters in Parameters for Slave Function (address: 060E
H
,
060F
H
).
• Set whether to enable or disable Data consistency dedicated
instruction in Data consistency dedicated instruction setting for
slave function (address: bit 1 of 0633
H
).
2) In Slave Function Transmit Data (address: 0C00
H
to 0C3F
H
), set initial
values of on/off information to be sent to the master node.
3) Set Auto Configuration Request (Y15) and Request for Saving
Parameters to Flash ROM (Y17) to off.
4) When I/O Communication Request (Y11) is set to on, the parameters
are checked.
5) When the parameter check is succeeded, I/O communication with the
master node is started and I/O Communicating (X01) is set to on.
Note that, until receiving an I/O communication request from the
master node, the module waits for connection establishment.
•
Data sent from the master node are stored in Slave Function
Receive Data (address: 0B00
H
to 0B3F
H
).
•
The on/off information to be sent to the master node is set in Slave
Function Transmit Data (address: 0C00
H
to 0C3F
H
).
