10.1 Cable Information
General This section includes information on cables which should be used for the
installation.
Signal Classes Power Supplies external motors and brakes.
Control signals Digital operating and data signals (digital I/O, safety stop, etc.).
Measuring signals Analog measuring and control signals (resolver and analog
I/O).
Data communication signals Gateway (field bus) connection, computer link.
Different rules apply to the different classes when selecting and laying cable.
Signals from different classes must not be mixed.
Selecting Cables All cables laid in the controller must be capable of withstanding 70°C. In addition,
the following rules apply to the cables of certain signal classes:
Power Signals Shielded cable with an area of at least 0.75 mm² or AWG 18. Note
that any local standards and regulations concerning insulation and area must always
be complied with.
Control Signals Shielded cable.
Measuring Signals Shielded cable with twisted pair conductors.
Data Communication Signals Shielded cable with twisted pair conductors. A
specific cable should be used for Gateway (field bus) connections and Ethernet.
CAN bus with DeviceNet for Distributed I/O units Thin cable according to
DeviceNet specification release 1.2, must be used. The cable is shielded and has
four conductors, two for electronic supply and two for signal transmission. Note that
a separate cable for supply of I/O loads is required.
Allen Bradley Remote I/O Cables according to Allen Bradley specification, e.g.
so called ‘Blue hose’ should be used for connection between DSQC 350 and Allen
Bradley PLC bus.
Interbus-S Cable according to Phönix specification, e.g. so called ‘Green type’
should be used between the I/O unit, DSQC 351 and external Interbus-S units.
Profibus DP Cables according to Profibus DP specification should be used for
connections between the I/O unit DSQC 352 and the external Profibus DP bus.
Ethernet Shielded twisted pair conductors (10 Base T STP).
CCLink Cables according to Mitsubishi specification should be used for
connections between the I/O unit DSQC 378 and the external CCLink bus.
