Handling of the Objects
16.1.5 Sequence of Communication
A request from the master is always
answered with a reply from the slave. Each PPO can only accept
one request or one reply at a time. In this way, a defined hand-
shake procedure between master and
slave must be complied with.
In the initial situation, the request
and reply identification must = 0. The master sets its request
identification and waits for the slave to change the reply identification from 0 to ≠
0. Now, the reply
from the slave is available and can be evaluated. Thereupon, the master sets its requ
est identification
= 0 and waits for the slave to change the reply identification from ≠ 0 to 0. With this, the
communication cycle is completed and a new one can start.
Attention!
The slave only replies to new requests if it has reacted to the request
identification = 0
with the reply identification = 0.
