Hello. The differential inputs and outputs (I/O) from the CPU1217 is handy for motion control applications. Connections with encoders, servo-drives and speciality motion controllers are what those I/O is meant for. Transmission of higher pulse rates is possible over longer distances with noise immunity which 'normal' I/O cannot provide. The I/O cannot be used for serial communication like Modbus RTU. The specifications of the CPU1217 can be found in the System Manual of the S7-1200. [https://support.industry.siemens.com/cs/ww/en/view/109772940] Regards. |
