  1. Hello. How can I get bit addressing of defined variable in function block? For example: - I define variable type DUINT with name Double_VarI_INT. - I want to get or set one bit out of it (its double word). - If I use Double_VarI_INT.0 I got error. Best regards.
  2. 505 workshop addressing

    Hi,  I'm attempting to convert some old Siemens workshop 505 code to control logix and i have basically no siemens experience at all and i'm confused as to how to tell what actual output card X1 or X2085 is referencing??   same with inputs.   
  3. Hello all, i'm looking at installing a completely new network for our PLC system, using a ring topology. at the same time i would like to incorporate the IP cameras and VOIP into the same network.  each system is on a different sub net, PLC = x.x.1.x, Cameras= x.x.2.x, VOIP= x.x.3.x estimated camera traffic will be 25 Mbps, PLC 10 Mbps, VOIP no more than 1 Mbps  switches would be capable of 100 Mbps  question: managed or un-managed switches? if it is possible to use un-managed without affecting operations then this would be a massive cost saving    please only comment if you have practical experience implementing this  many thanks Dan  
  4. Hello. I'm trying to use index addressing inside function block.  The command *D200 doesn't work. Is it necessary to use IR0, ID0,... inside function block? Thanks. Best regards

  6. I have a PLC that i just had to replace the old PLC was an Omron FA-350A the new PLC is a CMP1A-40CDR-A-V1. The programs are almost identical however there are some I/O changes that will need made. I am used to allen bradley PLC's and this is my first time using CX-Programmer. The PLC came preloaded with what was supposed to be the correct program although almost all of the I/O was programmed to the same addresses. I have no idea how the Addresses are structured. Would anyone be able to explain them or point me to a resource. There are also some 200.XX addresses are those bit storage locations? Thank you, Mike
  7. I have never worked with Point IO and wonder how the addressing for inputs and outputs are assigned? Is there a way to tell the PLC what addresses should be used for IO on the remote? I am planning to use the following: 1734-AENT 1734-OW4 1734-OW4 1734-IE4C
