Entering the Local and Remote TSAP for a Siemens S7-200 PLC

Last Update: 11/7/2018

The TSAP is displayed in MicroWin's Ethernet Wizard. When accessed from V memory, the value may be in decimal form. For example, if the TSAP is 10.00, the V memory value will be 1000 hexadecimal or 4096 decimal. The values entered for Local TSAP must be in hexadecimal notation; in this example, the value "1000" would be entered. Users can simply drop the decimal point from the TSAP displayed in the MicroWin Ethernet Wizard.

Note: After the PLC's program is changed, it must be power cycled.
