After you open the TIA Selection Tool, you can select a device series under “New device.” The “Power supply” device series offers you the 24 V DC power supplies for the SITOP compact, LOGO!Power, SITOP lite, SITOP smart, and SITOP modular product lines including SIPLUS variants and SITOP PSU8600 (with the system configuration via “Configure”).
You can select the suitable device either via the product catalog or based on technical properties input voltage, output current, or environmental conditions. Use the “Compare” function to compare selected products based on their technical properties. The tool displays properties that are the same and different. You can export the comparison as a PDF file.
Once you have selected a power supply, you can add suitable redundancy and/or selectivity modules from the product catalog via “Accessories.” This applies to all power supplies except for the PSU8600 power supply system.
You configure the SITOP PSU8600 power supply system when you select the basic PSU8600 device. To do so, click “Configure” to open the product range of add-on components for the respective basic device: The CNX8600 expansion modules and BUF8600 buffer modules are selected via the product catalog. The maximum possible combination of expansion and buffer modules is automatically taken into account in the system.
After starting the 24 V DC Power consumer view, you see an overview of all 24 V DC loads that you have already selected in the TIA Selection Tool for the project. The respective rated and peak currents for the consumer are shown in the “Details” field. For configurations such as the S7-1500, the “Details” information field provides a detailed view of the current calculation with intrinsic and load consumption. In addition, information messages remind you that a load power supply has not been connected yet. You can add further loads.
Click “New power supply” to create an unspecified power supply. You can quickly connect it with the desired 24 V DC loads individually by dragging or with all loads at once by right-clicking and selecting “Connect.” The total of the required output currents is automatically determined, displayed in the “Details” information field, and taken into account when another suitable power supply is selected. The “Edit” button opens the selection field for a suitable power supply.
Only devices that deliver the total required current for the loads to be supplied are displayed here. In addition, you can define parameters during the selection process: reserve for additional loads, coincidence factor, input voltage, product line, redundancy. Click “Copy” to copy the selected power supply and, if applicable, the suitable redundancy module to the total order list. You can make subsequent changes at any time.
The suitable power supply has been selected and added to the project and the product list. The tool indicates this with a green check mark.
In the “Details” information field under “Properties” of the power supply, the tool now displays a table with the parameters relevant to the selection including target and actual values and current reserves for additional loads in the “Difference” column. You can click “Edit” to change the selected power supply at any time. In addition, you can connect additional loads.
