Does cs3000 sequence control only run in automatic mode?
When conditions are met, run in automatic (mode).
Your sequence control is done in ST16 or SFC. When your ST16 or_If the mode of the UTSW module is automatic, it will automatically run according to the program you programmed in advance. If the mode of both is manual, the programs involved cannot be executed.

Both H and L can set your internal switch to 1, but when your conditions are not met, H will keep the internal switch in the 1 state. If it is L, when the conditions change from satisfied to unsatisfied, the internal switch will be automatically set to 0. For example: A0 A1 A2 C01 %SW0001.PV ON YNN A01 %SW0002.PV HYN A02 %SW0003.PV LY A1 A2 A0 I simply wrote the above program. When the program reaches step A1, if 0001 is turned OFF, the switch status of H is still 1, but the switch status of L becomes 0. If you want to set 0002 to 0, you can only set it to 0 by adding the opposite action. To put it simply, one is a holding action and the other is a non-holding action.

Reply 6# qf2008 There are a lot of information on self-control sharing. You can search it. If you can speak English, you can learn it directly.* Just M information.
