Encoder Interface (Htl/Ttl/Ssi) - Siemens SIMOTION D410 PN Manual

Connectable devices
The following devices can be connected to the PROFINET interface:
● PG/PC programming devices (communication with SIMOTION SCOUT / STEP 7 and
● SIMATIC HMI devices
● Distributed I/O
● Other SINAMICS drive units (e.g., CU310 PN or CU320 with CBE20)
