Is there a limit to the number of S-Cables which can be used when connecting additional rows of I/O modules?
SmartStruxure is being installed into an existing building and the current controllers are split into several rows.
A maximum of 5 cables can be used on an IO back plane. You can serially connect up to 2 S-cables in a row to extend the length.
