The table below shows typical delay times that have been determined under laboratory con-
ditions for frequency bands without any interference. The delay times may be higher or
lower in practice. The delay time is roughly doubled with each repeater in the network.

I/O data mode: the telegram length depends on the number of I/O extension modules.
Serial data mode: the telegram length depends on the protocol used and the terminal devices that are connected to the serial interface.
