Error codes are added to application log only when device description includes SafeErrorLog library. In SC52 device description 3.5.10.6 or later is required.
See also How to use application error log.
Supported platforms: CODESYS 3.5 SAFETY
This section describes how to review generated code for safety project diagnostics.
This guide focuses mainly on safety related implementation.
S_Safety_Status (PRG)
This program contains conditions for safety related diagnostic conditions.
Verify that the program checks the hardware specific diagnostic status OK flag
Verify that the program checks the SRDO signature valid condition
Verify that program checks the safety parameters valid condition
Verify that the program checks the GFC status

G_CONSTANTS (GVL)
The limits used in hardware diagnostic initialization are defined in the G_CONSTANTS global variable list.
In MultiTool 6.3 or later, or MultiTool Creator it is possible to adjust some of the limits in MultiTool Creator's diagnostic tab. In previous versions, the constant values are hardcoded.
Verify that the generated constant values are within range.
