Siemens PLC Guides

Older PLC's were always shipped with a default IP address. However, the modern PLC such as Siemens S7-1500 PLC does not have default IP adress. Instead, the PLC TAI Portal software includes "online" tools for assigning the IP address.

Connecting to PLC steps

Open TIA Portal

• Use TIA Portal to connect to the S7-1500 PLC

Configure Hardware

• In TIA Portal, you'll configure the PLC's hardware.

Assign IP Address

• In the hardware configuration, you'll specify the IP address you want to use for the PLC, along with the subnet mask and gateway address.

Download and Start

• After configuring the IP address, you'll download the hardware configuration to the PLC and start it.

Factory Settings

• If you need to reset the PLC to factory settings, you can use TIA Portal to do so, which will also reset the IP address to 0.0.0.0.

IP Address Conflicts

• Be aware of potential IP address conflicts on your network. It is always best to power up one device at a time and configure the IP adress. Duplicate IP address have unpredictable results that does not immediately indicate the fault.
