I/O Response Time between CompoBus/S Slaves
The I/O response time between CompoBus/S Slaves depends on the cycle
time and I/O timing.
Minimum I/O Response
Time
The minimum I/O response time is the CPM2C-S program execution time plus
the cycle time calculation time.
Maximum I/O Response
Time
The maximum I/O response time is as follows:
(2
×
CPM2C-S cycle time) + CompoBus/S communications time + Compo-
Bus/S Slave input delay + CompoBus/S Slave output delay
Note
The Slave input is not read for almost one PC cycle because it goes ON just
after the start of CompoBus/S communications processing (*1). The input is
read during the next CompoBus/S communications processing cycle (*2).
