Bulk Set Output
Sets all outputs in one go.
If all output logic status are managed by an external application (for example, by a computer application), this instruction allows freedom, speed of execution and a significant time saving. Differently from setting one output at a time, the bulk set output is simplier and faster by passing this work to MBx24 it self. It is bit oriented by clustering 8 outputs in a byte where ones ('1') mean an ON state and zeros ('0') the OFF state.

Remarks
First output bank (S1) -> Outputs from 1 to 8.
Second output bank (S2) -> Outputs from 9 to 16
Third output bank (S3) -> Outputs from 17 to 24.
Fourth output bank (S4) -> Outputs from 25 to 32.

| MSB 7 | 6 | 5 | 4 | 3 | 2 | 1 | LSB 0 |
|---|---|---|---|---|---|---|---|
| O1 | O2 | O3 | O4 | O5 | O6 | O7 | O8 |
- MSB (Most Significant Bit): The first output of the bank (O1).
- LSB (Least Significant Bit): The last output of the bank (O8).
Each bit corresponds to an output:
- O1: 1st output
- O2: 2nd output
- And so on...
Example
Turn ON all the first and last outputs for all banks (1 and 8,9 and 16,17 and 24, 25 and 32) of the MBx24 with ID address of 55:
| 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13 | 14 | 15 | 16 | 17 | 18 | 19 | 20 | 21 | 22 | 23 | 24 | 25 | 26 | 27 | 28 | 29 | 30 | 31 |
