6 SEQUENCE PROGRAM USED FOR POSITIONING CONTROL
Intelligent device station access
request signal (RY(n+7)E)
Intelligent device station access
complete signal (RX(n+7)E)
(d) Using the FROM command
This is used to read the D75P2-designated buffer memory.
When the FROM command is used, the transmission buffer (master
module buffer memory) for the control data size, and the reception buffer
(master module buffer memory) for the read data size are used.
The data designated with the transmission buffer is read from the D75P2
buffer memory using the intelligent device station access request signal
and complete signal (RY(n+7)E and RX(n+7)E).
