F_Block_ID not supported

ABB · AC500

¿Qué significa 26 ?

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.

Causas comunes

  • 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.
