  1. Limit

    Looking to set a limit in my logic that returns a bit if my process value falls between the lower and upper limit values. Looking at LMT(680) but it does not appear that it switches a bit just passes the value through. Any ideas?

  3. ZCP Instruction

    Hi group! I am struggling to figure out what I am doing with the Limit instruction (ZCP 088).  I want to turn on a permissive if the compared word is between 1 and 12.  Rockwell makes this so much easier!!! It looks like my "=" instruction is not correct but this is how they show it in the manual???????    
  4. Hi, I was wondering if there is a way to limit the number of allowed on-line connections at a time to a PLC? Like can you somehow set in the PLC parameters that only 1 'connection' can be on-line in the device at a time? Thanks Edit: I'm referring to connections from the TIA portal - not HMI / ethernet connections and so forth
  5. Hi, Iam new to schneider electric PLC drive programming and also to canOpen communication. I have an LMC058 PLC and there are three Lexium 32A drives connected via canOpen which inturn controls three servomotors. My question is how to find/ read hardware limit status of the axis in which limit is connected to a digital input pin of the drive. Even though the axis is properly working by configuring the digital input pins we are unable to get the digital input status of the drive. In the drive manual its given that the digital input status can be read from canOpen address 3008:F(hex) we dont know how to read the status during run time in the program . Can any one advise me how to read that address. I tried SDO_read function but its giving me error(canOpen network id Unknown). Thanks in advance.
