Hi

I would like some assistance on the total cable length of spurs allowed on a segment running at 1.5 Mbps. The existing network has a daisy chain configuration between motor control starter cubicles with the final connection to each starter as a Spur into a Simocode pro V unit. 

Hello,

Have a look in the following manual:

SIMATIC NET PROFIBUS Network Manual System Manual

See page 42

Best regards,

Wizard
