Cyclic Transmission Time; Startup Procedure - Toshiba 2000 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 PF611 output area, transmit to slave, receive from slave,
and write to PF611 input area is shown in the following table. (Excluding controller I/O time
and slave side I/O time.)
