Bus cable length
) Note!
ƒ The permissible cable lengths must be observed.
ƒ Please observe the reduction of the total cable length due to the signal delay
of the repeater, see example below (¶ 210).
ƒ During mixed operation, multiple nodes are operated on one mains.
ƒ If the respective total cable lengths of the nodes differ at the same baud
rate, the lower value must be used for the determination of the max. cable
length.
Total cable length
1. Check whether the total cable length is complied with.
The total cable lenth is determined by the baud rate:
Baud rate [kbps] Max. bus length [m]
