TI545/TI555 System Manual

7.5 Troubleshooting by Using Status Words

addition to auxiliary functions, the CPU provides operational information

in the form of 16-bit status words. Status words can be read with your

programming device. Status words can also be used within a RLL program

thus allowing the system to execute diagnostics during run-time conditions.

Status words supported by the CPU are described in detail in the

SIMATIC
