dear sir please may i know about latching, how can i create the booster pump? latching by 1 duty and stand by , when the A pump cycle completed then motor should run B , this is working in every cut-off. for example: when pressure maintain by 1 duty A after cut-off motor B will run to maintain the pressure. i am facing to find the latching relay function in S7 1200 plc . thanks ------------------------------------------------------------------------------------------ |

-(S)- will SET a digital output until a RESET -(R)- is activated (or someone accidentally includes a -( )- for the same tag and messes everything up). Use F1-Help to find all the instructions available for your PLC. Or, expand the instruction pane and look through all the options.

There are a lot of possibilities: with SET operator over a internal boolean or output, but also SR, or RS for the same kind of tags. Attachment2023-07-11 20_54_24-C__Data_Sistemi_=1040_06872_dev_06872_06872_As01_1A1_06872_Plc01_1A1_SB_TiaPorta.png (322 Downloads) |
