Indirect DM/EM BCD Error

What does A295.09 mean?

An indirect DM/EM BCD error has occurred, causing the AER Flag to turn ON, and the PLC Setup is set to stop operation for an instruction error. This means an indirect address or the word holding it is not in BCD format when BCD mode is specified for DM/EM access, contributing to a fatal program error (0x80F0). The error address is output to A298/A299.

• An indirect DM/EM address or the word holding the indirect address is not in BCD format while BCD mode is specified for addressing.

Click steps to track your progress.

1. 1

   Find the program address where the error occurred using A298 and A299.

2. 2

   Correct the indirect addressing (either the indirect address itself or the word holding it).

3. 3

   Alternatively, change the system to binary mode if BCD is not strictly required.
