PLC Link Communication Time
This section describes the communication time of the DV-90.
„ The communication time required for data transmission (when writing one data item
in the normal verification mode)
The time required for data transmission from the DV-90 to the PLC is shown below.
Note that this time may vary depending on the scanning time and the PLC model.
When the baud rate is 9600 bits/s
„ The communication time required for starting reading in the Read Trigger Communi-
cation Area “X+06”
When the reading of the connected BL Series is controlled by using the Read Trigger Notice Area,
the communication time before starting reading by feeding the ON trigger is shown below.
When the baud rate is 9600 bits/s
„ Communication time required for active record number change
The communication time when the active record number in the active verification mode is changed
on the PLC link is shown below.
When the baud rate is 9600 bits/s
