How to acquire the values of CFP 1800 use FP read via RS 232?

Hello

We have an application in which there is a provision of the redundancy of the system. By redundancy, I want to say that I have a CFP-2120 and a host PC. Both are accquiring real-time AI module using concept shared Variable values. Each of these variables is linked with a particular channel of the Module & will acquire the data automatically. Initially when the system is Ok, the PC acquires data from the PSC 1800 using ethernet. Now, suppose that the ethernet connection has been lost, now that the PC will not be able to acquire. At this point, I want my PC to acquire data from the PSC 1800 using RS 232. In this case the binding of the variable with channel won't be of such use. I think that in this case, what I can do is to accquire data .vi FP READ and update the variable by plugging the variable for each channel.

What else will be the solution. Can someone tell me if my colleague and I are on the right track or if the best solution is here, please share with us.

The move will be highly appreciated.

Thank you best regards &,.

Hello

You're going in the right direction for creating redundancy for you system controller PSC.

Here is the link for system redundancy with two components:

I hope that this should help.

    For example

    Is actual query-> Select * from employees where name like in("SCOTT", "JAMES", "ALBERT",...);

    I want to--> Select * from employees where name like(SCOTT, JAMES, ALBERT...); -without the use of single quotes.

    Why I need this application, I need to retrieve the records more than 200 employees in a select statement by using name in where clause.

    In short... you can't.  The channels are channels, and SQL and PL languages dictate that the string literals are provided within single quotes.

    I don't see how trying to retrieve more than 200 records of employees in the select statement means that you must get rid of the quotes.

  • urgent request: how to read the value of a register using VISA read?

    Hello world

    This is a very urgent investigation. can someone help me please? Thank you very much!!

    I wrote a few commands in several registers using VISA write. now, I want to read the value of a different register.

    But the bytes returned are just the commands, I wrote before and a few other commands that I don't know what they are for.

    This is the format of the command, and I enclose the sheet... I want to read the value of register (0 * 41)

    .

    Ravens, if you have something more than me, do not so much it at all =)

    The command you have posted has several components:

    The gray area of the transport layer uses for a checksum

    several bits set to 0.

    a single bit to define if it's a read/write operation

    a byte to identify the register of interests.

    two bytes for the data.

    With what you have provided, there are only three things we need to worry:

    (1) set the R/W bit to 0 to mean we're reading rather than write.

    (2) set the second byte 0 x 41 to focus on the register of interests.

    (3) with a reading, I can't imagine the last issue of two bytes.  They probably ignored.  The documentation you provided does nothing to explain this.  The most logical thing I can think is that these two bits contain the data, you go to the registry if you set the R/W bit to 1.

    There are two parts to this communication.  The first part is an entry VISA to send this control unit.  It is likely that you will need to complete the message.  You will need to know how to do this.

    The device must respond with the message that you mentioned in the original post.  Crows is right.  He's coming back as a string.  You can use the subset of string to separate the components defined by the standard.  You can use these components to determine if the data is legitimate and then do what you want with the data.

  • How to connect the value of the input string to numeric values

    Hello

    I'm trying to figure out how to connect the value of unique user input string to numeric values. Basically I want the user to enter the name of a gas that I have a list for (I think I put the list of gases in a table >). Then I want to match numeric values 2 'a' and 'b', according to which gas, name of the user has set. These 'a' and 'b' values will be automatically matched with the name of the gas in a list that I put. For example, hydrogen gas has the value 3 for "a" and 4 for "b. when the user puts the ' hydrogen' name in a string constant, automatically 'a' and 'b' must be issued.» I have connect a and b to a formula

  • Acquire the values only when the digital output is high.

    Hello

    I work with test of transistor, whose door is controlled by the digital release of USB6289, related to BNC2120.

    Test plan:

    Door 1.transistor is enabled for 5seconds, with P0.0 for example

    2. then, everything remains off for 1secondes.

    3.p0.1 is used as digital output to activate the circuit passing him curent through in the opposite direction, P0.1 goes high for 3 seconds, PS: Gate is off.

    4. the same cycle repeats again.

    My question is to store values to the output of the transistor when P0.0 and P0.1 goes high, and these values should not change until my digital outputs respective again go high.

    I can access transistor by continiously read out my power supply values.

    and in the State off I want to read AI0 because at that time, my power supply is off, so that I can activate the circuit to pass the current in the opposite direction.

    Again, my question is to gain the output through power value when P0.0 is high and store them until the transistor turns on.

    and even for P0.1, acquire the value of output through AI0, when P0.1 is high and store it until it goes high again.

    Hopefully, I'm able to explain my problem clearly.

    Please help me.

    Think about what States (object:statemachine and determine when to use sequence Structures) do you want from t0... t(n-1), IF DAQmx generates outputs and/or inputs are absorbed and what needs to happen (event timed out), before move you on to the next 'State '.

    type def 'enum' with your different States:

    • initialize
    • wait (the user initializes times (sec) set for States, or whatever and presses button 'Start')
    • T0 (generate DigOutputs, store acquired data AnalogOutput (string output number) the register shift, before moving to the next State > user 'set time' must elapse (Note: the wait function allows you to control the rate of execution of loop and allow the CPU to respond to external events and system tasks and avoid using wait functions at the same time an operation of software...))
    • ...
    • t(n-1) if ' end (made requirement) "> goto 'stop', ' another (not requirement not)" > goto regardless of 'State '.
    • stop
    • write a text file of data (string).
