Electrical connection Proline Promag P 100
22 Endress+Hauser
Cable type Twisted pairs
Loop resistance ≤110 Ω/km
Signal damping Max. 9 dB over the entire length of the cable cross-section
Shielding Copper braided shielding or braided shielding with foil shield. When grounding
the cable shield, observe the grounding concept of the plant.
Modbus RS485
The EIA/TIA-485 standard specifies two types of cable (A and B) for the bus line which can be
used for every transmission rate. Cable type A is recommended.
Cable type A
Characteristic impedance 135 to 165 Ωat a measuring frequency of 3 to 20 MHz
Cable capacitance <30 pF/m
Wire cross-section
>0.34 mm

Shielding Copper braided shielding or braided shielding with foil shield. When grounding
the cable shield, observe the grounding concept of the plant.
EtherNet/IP
The standard ANSI/TIA/EIA-568-B.2 Annex specifies CAT 5 as the minimum category for a
cable used for EtherNet/IP. CAT 5e and CAT 6 are recommended.
For more information on planning and installing EtherNet/IP networks, please refer to
the "Media Planning and Installation Manual. EtherNet/IP" of the ODVA Organization.
