I’m seeking help from those with more experience – I’d like to understand the meaning of the logical statements in the Bentley 3500 channel relay module
Thread Content
I have two questions and would like to seek advice from the seniors. 1. In the Bentley 3500 logic statements shown in the figure above, taking the second statement S07C01P01A2 as an example, S07 represents Slot7, C01 represents Channel1, and A2 represents Danger. So what does P01 represent? 2. In the instructions in the help manual shown above, there are two types of “AND” operations: Normal AND and True AND. Among them, (1) Normal AND refers to the logic output when two or more channels are combined using the AND operation; once one of these channels enters a non-OK state (such as a fault in the sensor circuit), that channel is removed from this logical combination. The remaining channels serve as the output of the logic (2): True AND – the logic result that is obtained when two or more channels are combined using the AND operation; even if one of these channels enters a non-OK state, it will still remain part of the overall logic. These two sentences are not difficult to understand, but I would like to ask the more experienced colleagues: how are \"normal and\" and \"true and\" set up during configuration, and where can they be found in the software? I haven’t been able to find it; I hope experts can offer some guidance. I am extremely grateful.
I found some information stating that P stands for proportional value, which translates to a value that is proportional or balanced. How should this be understood?
1. Choose between true AND or normal AND mode in the 33 card configuration; when Channel 1 is set to active, there is an And Voting Setup option where you can select true AND or normal AND. 2. The difference between true AND and normal AND is that one considers only the status, while the other takes into account both the value and the status. 3. PXX represents the value you choose; in the 42M card, various values are available for selection, including the pass frequency value, 1x frequency value, 2x frequency value, etc. Of course, you need to select the corresponding parameters in the Setpoint settings for them to be displayed in the 33 card configuration
The logic of AND is the logic resulting from the AND operation of two or more channels; when one of these channels is in a Not OK state, that channel is excluded from this logic, and the remaining channels produce the logical output. The logic of AND gate is such that even if one channel is in a Not OK state, it is still included in the overall logic
