9.6. Protocol macro data
Protocol macro data consists of sequence, step, send/receive message, and matrix. Its
composition is described as follows.
●
When there is only one receive message format for a step (send/receive once)
•
Set one send message and one receive message for the step
Sequence No.900
Step No.00
Send message 00
Receive message 00
•
•
Step No.yy
Send message yy
Receive message yy
Sequence No. xxx
xxx: 999 max. yy: 15 max
●
When there are several types of receive message formats for a step (send/receive once)
•
Set the send message and matrix for the step
•
Set several types of cases (receive messages) for the matrix
Sequence No.900
Step No.00
Send message 00
<Matrix>

•
yy: 15 max
zz: 14 max
Case No.zz

Case No.15 is automatically set
Case No.15

9.6.1. Composition of Protocol Macro Data
In this protocol macro data, there is only 1 type of receive message (SD_RDCODE) for the
send message (SD_RDCODE). Therefore, the following composition is used without using the
matrix. Refer to
9.6.6. Receive Message Settings
for details.
Sequence No.900
Step No.00
