Note The PLC cycle time when data link words exceed 12,000 using a CS/CJ-
There are three points shown in the diagram above where processing is
delayed, increasing the data link I/O response time.
1. The input arrives in the PLC just after I/O refreshing, causing a delay of up
2. Data exchange occurs just after the PLC at node #1 passes the token,
3. At node #7, data from the previous data exchange is still being transferred,
The equation for maximum data link I/O response time is as follows:
series Controller Link Unit with unit version 1.2 or later is calculated as fol-
lows.

to one cycle before the input is read into the PLC.
causing a processing delay of up to one communications cycle time until
the next token is received. There is a maximum delay of one communica-
tions cycle after the token is received.
causing a delay of up to one cycle before the input is read into the PLC. (If
the cycle time at node #7 is longer than the communications cycle time, the
processing will be delayed for two cycles.) Also, if the total number of data
link words exceeds the maximum number for a single exchange, the data
exchange will be divided up and there may be a delay of one to two addi-
tional cycles.
The maximum number of words that can be exchanged in a single data ex-
change is approx. 7,800 words for CS/CJ-series PLCs, approx. 3,700
words for CVM1 and CV-series PLCs, approx. 4,000 for C200HX/HG/HE
PLCs, and approx. 1,200 words for CQM1H-series PLCs.
