Sequence generator Function Code FC 161 Harmony
Customer has configured Function Code 161 , it is sequence generator , it has configured trigger pin to a specific block number , reset connected to another block number and jump pin to another block number , if jump condition is true it jumps to step4 it is only one sequence generartor block but there are some in whole system.
The questions :
We have seen in Step1 timer 15 secs , in step 4 timer is 15 secs also , step 5 10 secs, others steps the step timers are 0 sec.
when the trigger condition is true ( transition from 0 to 1) , sequence generator goes to step 1 keeps for 15 secs output 1 to open a specific valve then because step2 , step3 are step timer 0 secs , it goes to STEP4 to open the valve related to this STEP4 , then goes to step 5 10 secs( output 1), for steps (6, 7, 8) it does not any action because the step timer is 0 secs , when it reaches the last step , it finishes the batch . Is that correct?
Timer step for 2, 3, 6, 7, 8 is 0 but they keep the mask for each one.
If the sequence is at step1 which it keeps for 15 secs and for example at 7 sec , the jump condition changes to true ( step jump number is 4 ) , what happen with step1 , does it wait until finish 15 sec then jump to step 4 ?
if the reset condition is true while Sequence step is at step1 opening the specific valve , does it change the output to 0 ( default mask is 0000) and close the valve? Is that correct?
I am curious about the following , because FC161 could be stepped through event or time basis
In this same configuration that I have sent , if the step 4 is being executed and for any reason trigger ( TAG1 OR TAG2 OR TAG3) change from 0 to 1 transition , what does happen in this case ? Does it jump to next step inmediately, step 5 ? or if the step 5 is being executed and trigger condition changes from 0 to 1 transition and as I have mentioned above step 6, 7, 8 step time is 0 secs , what happen in this case ?
