Cyclic Transmission Time; Startup Procedure - Toshiba V Series User Manual

4.2 Cyclic Transmission Time

The cyclic transmission time depends on the transmission speed, number of slaves, and
the number of transmitted words.
The time required to read from the PF311 output area, transmit to slave, receive from
slave, and write to PF311 input area is shown in the following table. (Excluding controller
I/O time and slave side I/O time.)
