Example A
Example B
I = Input Module (8 or 16Ćpoint)
O = Output Module (8 or 16Ćpoint)
BT = Block Transfer Module
1 Output modules use the same output image table bits
2 Can be input or output module (8 or 16Ćpoint) singleĆslot block transfer module
3 Must be empty if corresponding primary slot is block transfer module
