Installation Guidelines and Limitations

The Siemens 6ES7290-6AA20-0XA0 allows system expansion into a two-line configuration for improved cabinet layout flexibility . For electromagnetic compatibility reasons, users can employ only one I/O bus extension cable per CPU or expansion module chain . Proper installation requires securing the cable with cable ties to prevent connector loosening in vibration-prone environments. This cable serves as a spare part for maintaining existing S7-200 installations.
