A power tool system includes a portable power tool ( 10 ), a stationary control unit ( 11 ), and a cable assembly ( 12 ), which includes a multi-core cable 15 and connection pieces ( 13, 14 ), for communicating power and/or signals between the power tool ( 10 ) and the control unit ( 11 ). The cable assembly ( 12 ) is provided with an electronic memory module in the form a data chip ( 16 ) for storing data relating to the identity and operation characteristics of the cable assembly ( 12 ) as well as data concerning the compatibility of the power tool ( 10 ), the control unit ( 11 ) and the cable assembly ( 12 ). The data chip is arranged to register and accumulate the number power tool operations performed via the cable assembly ( 12 ) and to indicate when a predetermined limit for power tool operations as regards mechanical wear of the cable assembly ( 12 ) is reached. |
