3.2.2. Connecting
The encoder provides three M12 flange connectors.
Two M12 flange connectors (D-coding, according IEC 61076-2-101) serve for PROFINET connection.
For voltage supply use A-coded M12 connector only.
For the bus lines both D-coded M12 connectors may be used at will. However, together with a planned
topology it may be necessary to observe the correct assignment (P1/P2).
Seal up the unused cable gland using a sealing bolt (transport and dust protection).
No settings have to be done inside the encoder. In contrast to Profibus, there is no need for setting a node
ID or a terminating resistor. All settings required for encoder access are made in the engineering tool (e. g.
Siemens
®
Step7
®
or TIA
®
Portal).
