Remove the I/O connectors and wiring from the SM. If there is another SM to the right, repeat this. The S7-1200 expansion cable provides additional flexibility in configuring the layout of your S7-1200 system. You install the expansion cable either between the CPU and the first SM, or between any two SMs. Ensure that the CPU and all S7-1200. This device is designed for use with WinPM™, Siemens' Microsoft Windows™-based power monitoring and control software. The device communicates with a supervisory computer running WinPM by way of the SEAbus communications protocol. Plug the expansion module's bus connector into the bus connector. It must withstand temperature difference stress, resist short-circuit shocks, and ensure no insulation breakdown—can your solution achieve absolute safety? For the power industry, zero accidents is the bottom line. They are not used when replacing a previously installe. Memory and peripheral devices ar e connected to the processor through a group of lines called buses. They are also referer red as bus slo ts o r expansion slots.
