Problems found in the Centum VP chain
Thread Content
In the logical chain, the output terminal is HV-109.CSV.0; HV109 is the valve. What does CSV refer to, and what do the values 0, 1, and 2 represent respectively?； What does L stand for in SW-412.PV.L, and what other properties does SW-412.PV have?
CSV corresponds to the SIO function block; for valves, 0 usually means closed and 1 means open. Correspondingly, pump 0 stops and pump 2 starts. There are also some special forward/reverse/stop functions, etc. PV corresponds to the SW shared switch.
CSV is used for interconnection within a chain; it is generally applied to values of 0 and 2. For valves, 0 denotes closed while 2 denotes open. PV.L is also used for assigning values in the context of interconnection
SW-412 is a switch variable; what does L in SW-412.PV.L represent?
The meaning of L is determined by the previous assignment
