Remote I/O Communications Characteristics
Section 7-1
CS, CJ, C200HX/HG/HE (-Z), and C200HS PLCs
Minimum I/O Response
Time
The minimum I/O response time occurs when the DeviceNet Slave I/O
refreshing is executed just after the input signal is received by the master and
I/O is refreshed for the slave first in the next I/O refresh cycle.
T
IN
:
The Input Slave's ON (OFF) delay (Minimum value: 0)
T
OUT
:
The Output Slave's ON (OFF) delay (Minimum value: 0)
T
RT-IN
:
The Input Slave's communications time/slave
T
RT-OUT
: The Output Slave's communications time/slave
T
PLC
:
The PLC's cycle time
T
RF
:
The PLC's DeviceNet Unit refresh time
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 cycle time.
