1. A monitoring system for monitoring the condition of a line guided by a line guide apparatus, the monitoring system comprising:
a displaceable line guide apparatus (1; 41) for guiding a line between a stationary connection point and a connection point mobile relative thereto, wherein the line guide apparatus (1; 41) forms at least one mobile run (2) with a first connection end (2A) and a further run (3) with a second connection end (3A);
at least one line (13; 13A; 13B), which is guided by the line guide apparatus (1; 41); and
a monitoring device (10; 20; 30) having an evaluation unit which detects information about the condition of the line to be monitored;
wherein
the monitoring device comprises a first device (11) with an interface for data communication and a second device (12; 12′) with an interface for data communication, which devices are configured for data communication according to a protocol for digital data transmission;
the at least one line (13; 13A; 13B) is guided by the line guide apparatus (1; 41) and includes an electrical data line (13), the interfaces of the first and second devices (11, 12) for data communication being connected via the electrical data line (13); and
the evaluation unit is configured to detect information about the condition of the line to be monitored on the basis of an information technological quality feature of the data link between the first device (11) and the second device (12; 12′).
