Displaying The Status Of A Program In Statement List - Siemens SIMATIC S7-200 System Manual

Basic Concepts for Programming an S7-200 CPU
To choose the categories of values that you want to appear in the STL status
window, select Tools > Options and then select the STL Status tab. You can
choose to monitor three categories of values in the STL status window:
Operands (up to three operands per instruction)
Logic Stack (up to four of the most recent values from the logic stack)
Instruction Status Bits (up to twelve instruction status bits)
To obtain first scan information, place the PLC in STOP mode, enable STL status,
then select Debug > First Scan.
