Remote I/O Communications Characteristics
Section 7-1
Maximum I/O Response
Time
The maximum I/O response time occurs with the I/O timing shown in the fol-
lowing diagram.
T
IN
:
The Input Slave's ON (OFF) delay
T
OUT
:
The Output Slave's ON (OFF) delay
T
RM
:
The whole Network's communications cycle time (Refer to
page 131)
T
PLC0
:
The PLC's cycle time (instruction exe peripheral servicing)
Note
Refer to the information on each slave for details on Input and Output Slaves'
ON and OFF delay times. Refer to
7-1-2 CompoWay/F Communications
Cycle Time and Refresh Time
and the Operation Manual for the PLC being
used for details on the PLC's instruction execution and peripheral servicing
cycle times.
The maximum I/O response time (T
MAX
) is the total of the following terms:
T
