Pro PROFIBUS Line
(Line = Starts at DP Master and goes to last DP/PA Slave)
• Approximately 4 to 8 DP segments through the repeater
(see repeater data sheets)
• Recommended DP transfer rate 500 to 1500 kBit/s
• The slowest DP node determines the transfer rate of the DP
line
• Number of PROFIBUS DP and PA nodes ≤ 126
(addresses 0 to 125)
Per PROFIBUS DP segment
• Number of DP nodes ≤ 32
(Node = Devices with / without PROFIBUS address)
• Bus termination required at the beginning and end of each
DP segment!
• Trunk cable length (L
T
) see diagram (length dependent on
transfer rate)
• Cable length of at least 1 m between two DP nodes at
≥ 1500 kBit/s!
• Spur cable length (L
S
), at ≤ 1500 kBit/s: LS ≤ 0.25 m,
at > 1500 kBit/s: LS = 0.00 m!
• At 1500 kBit/s and ABB DP cable type A:
– Sum of all spur cable lengths (L
S
) ≤ 6.60 m, trunk cable
length (L
T
) > 6.60 m, total length = L
T
+ (Σ L
S
) ≤ 200 m,
maximum 22 DP nodes (= 6.60 m / (0.25 m + 0.05 m
spare))

Note
You will find detailed information regarding the “Ethernet” in the
interface description “COM/FCB400/FCH400/E/MB”.
