6. Restrictions on diverging sequence: Please refer to section 5.5 for examples
a) Max. 8 step points could be used for single divergence sequence.
b) Max. 16 step points could be used for the convergence of multiple diverted sequences.
c) Users can assign a step in the sequence to jump to any step in another sequence.
7. Reset step points and disable outputs
a) Use the ZRST instruction to reset (turn off) a specified step sequence..
b) Set ON the flag M1034 to disable Y outputs.
8. Latched step:
The ON/OFF status of the latched step will be memorized when the power of the PLC is
switched off. When the PLC is powered up again, PLC will resume the status before power-off
and executes from the interrupted point. Please be aware of the area for the latched steps.
9. Special auxiliary relays and special registers: For more details please refer to 5.6 IST
