In embodiments of the disclosure, the control elements or subsystems 202 (e.g., the I/O modules 204, the control modules 206, the power supplies 212, and so forth) are connected together by one or more backplanes 214. For example, as shown in FIG. 7, control modules 206 can be connected to I/O modules 204 by a communications backplane 216. Further, power supplies 212 can be connected to I/O modules 204 and/or to control modules 206 by a power backplane 218. In embodiments of the disclosure, cables 100 are used to connect to the I/O modules 204, the control modules 206, the power supplies 212, and possibly other process control system equipment. For example, a cable 100 is used to connect a control module 206 to a network 220, another cable 100 is used to connect a power supply 212 to a power grid 208, another cable 100 is used to connect a power supply 212 to a local power generator 210, and so forth.
