Computing the Cycle Time
Section 2-7
Here,
2-7-10 Pulse Output Start Time
The pulse output start time is the time required from executing a pulse output
instruction until pulses are output externally. This time depends on the pulse
output instruction that is used and operation that is performed.
2-7-11 Pulse Output Change Response Time
The pulse output change response time is the time for any change made by
executing an instruction during pulse output to actually affect the pulse output
operation.
Number of partici-
pating slave nodes
The number of slaves to which links have been established
within the maximum unit number set in the master.
Number of non-par-
ticipating slave
nodes
The number of slaves not participating in the links within the
maximum unit number set in the master
