F_Block_ID not supported
ABB · AC500
What does 26 mean?
The safety PLC configuration specifies an F_Block_ID that is not recognized or supported by the system. This indicates an incompatibility or incorrect setting within the safety function block configuration, which can prevent safety functions from executing correctly.
Common Causes
- Attempting to use a safety function block (F_Block) with an F_Block_ID that is not compatible with the current firmware version of the safety PLC.
- Project migrated from an older PLC generation to a newer one without updating or re-generating the safety function blocks.
- Incorrect device description file (GSDML) imported into the PLC programming software for the safety device.
- Typographical error or incorrect selection of the F_Block_ID during configuration in the PLC programming software.
- Corrupted library for safety function blocks in the engineering station's software installation.
Repair Steps & Checklist
Click steps to track your progress.
- 1
Verify the F_Block_ID configured for the specific safety function block against the documentation for the safety PLC and its firmware version.
- 2
Update the firmware of the safety PLC to a version that supports the required F_Block_ID, if available.
- 3
Re-select or re-insert the specific safety function block from the standard library in the PLC programming software.
- 4
Check the installed GSDML files for safety devices and update them to the latest versions.
- 5
Recompile the entire safety PLC project and download it to the safety PLC.
