STEP 7-Micro/WIN SMART makes it easy for you to program your CPU. In just a few short
steps using a simple example, you can learn how to create a user program that you can
download and run on your CPU.
All you need for this example is an Ethernet cable, a CPU, and a programming device
running the STEP 7-Micro/WIN SMART programming software.
2.1
Connecting to the CPU
Connecting your CPU is easy. For this example, you only need to connect power to your
CPU and then connect the Ethernet communication cable between your programming device
and the CPU.
Connecting power to the CPU
WARNING
Ensure power is off prior to installing, wiring or removing devices
Before you install or remove any electrical device, ensure that the power to that equipment
has been turned off.
Attempts to install or connect the wiring for the CPU or related equipment with power
applied could cause electric shock or faulty operation of equipment. Failure to disable all
power to the CPU and related equipment during installation or removal procedures could
result in death or serious injury to personnel, and/or damage to equipment.
Always follow appropriate safety precautions and ensure that power to the CPU is disabled
before attempting to install or remove the CPU or related equipment.
