Urgent help needed with a CS3000 issue.
Thread Content
Question 1. I saw that when others were programming, they used %sw0004 in a sequencer table to set the SIO instrument block to aut mode. I know it’s customized by the system, but I don’t know what it means. I hope experts can answer. Question two. I have created many sequential empty tables, but I have to manually switch to automatic mode every time I run a simulation. I would like to know how to enable automatic mode automatically. I saw a post before suggesting that another sequential empty table be created, but what I don’t understand now is that the sequential empty table created in this way is still in manual mode, right?
Reply 1# coolfires117 ST16 or LC64 is fixed: manual; set to AUT after creation is complete. This is to prevent unexpected jumps when you write out the sequence table and download it to FCS. The system’s built-in MAN gives you time to verify the system. Was it saved when you exited the simulation? If it is not stored, ST16 or LC64 will still be MAN; it must be manually set to AUT for the next simulation
There is another way to remain in automatic mode, which is to write a program using a computation block. It is not recommended in general; it can be used when there are few programs. It is still recommended to use sequential control for automation.
What does %sw0004 mean?

There are various ways in which the processing timing can be set for a sequential control table: “Choose either ‘Periodic Execution Type (T),’ ‘One-shot Processing Type (O),’ ‘Startup at Initial Cold Start/Restart (I),’ or ‘Restricted Initial Execution Type (B).” “...I saw a post earlier suggesting that another sequential control table should be created; that is, create such a table with a processing timing setting of I. In its Action settings, set those other sequential control tables that need to operate automatically to automatic mode as well. As for %SW0004, just check the IM manual – it’s just an ordinary switch. The manual describes it as follows: A4-10 ■ System Common Switches: The PFCS/SFCS common switches (element numbers: %SW0001 to %SW0200) are designed as system switches with fixed functions. Users can check the status of these common switches. The data related to the common switches %SW0004, %SW0005, and %SW0031 is entered by the users themselves. The common switches %SW0097 to %SW0200 are valid only when the extension common switch is set to 1 (valid).”
Reply to 5# jlshnlhj: Thank you for your help. I still have one question – I saw that in other projects, the pbs5c module is used to create a pop-up interface for controlling the motor’s automatic and manual mode as well as its start and stop functions. What does this module mean? I’ve tried hard for a long time but still can’t figure out how to use it.

Reply to 6# coolfires117: The PBS5C or PBS10C instruments that I understand are those that combine several internal switches in one panel; each button seems to be adjustable, allowing it to be pressed simultaneously with multiple switches or just one switch. In one project I worked on, product selection was involved, with a choice of 5 options out of 1, and this module was used for that purpose. Take a look at the M materials; what I said isn’t very detailed either.
