The maximum permitted field bus length depends on the
baud rate used. Fig. 1/12 shows the guideline values. De-
tailed information can be found in the manuals for your con-
trol system or bus interface.
The maximum permitted length of the branch line depends on
the total length of the branch lines and the baud rate.

terface for information on the T-adapter and the maxi-
mum branch line length which is permitted for your con-
