  1. Axis Attribute Error

    hello,   did you get this issue resolved. I am seeing the exact same problem.
  2. hello I have been forced to replace a TWDLMDA20DRT with a Schneider TM221ME16R. the plc is a slave but I am having trouble getting the Modbus data exchange to work like it did with the old plc. I have setup the serial port to use Modbus etc etc and I played about with the read_var FB but this wasn't required in the old plc so im confused as to why I would need to use it on the replacement. I have come across another FB send receive message but again i'm not too sure if this is required.  the master plc uses the msg2 and exch2 command. I believe I am just missing something very simple here.   Lighting Panel - Old_PLC.twd Lighting Panel1 - Master -.twd Lighting Panel - Pillar5 -.smbp
  3. Trouble with schneider ATV320

    Im using a 1769-L33ER and im trying to add in 3 schneider ATV320 drives.I want to connect over Ethernet/IP and im using a VW3A3616 card on each drive. I set the drives to Ethernet/IP, set a static IP then try and add in a generic ethernet module, set it to assembly 101/100. But only one of the drives connect properly. The other 2 have a yellow warning sign and in the properties under module info, the information looks ok apart from Owned - No. this is the only difference from drive 1 which says Owned - Yes. Am i missing some other configuration?Im also having trouble controlling drive 1, I was given an example program from schneider with an addon instruction for an ATV32 (they said it will work). I then added that addon instruction into my project and linked the relevant tags and parameters. I am getting some data in the input in controller tags But the addon instruction isn't working im not seeing any data.  Im guessing im missing something... Any help or point in the right direction is appreciated Example_ATV32_EthernetIP_RSLogix5000.zip Example_ATV32_EthernetIP_RSLogix5000.ppt

    ,The '"System".Cycle.InCycle' parameter is not permitted. No access is allowed to static I-DB variables. Remove this access from the safety program.,,,10:27:41 AM   can anyone shed any light as to why this would appear all of a sudden, worked perfectly well the last time i was onsite. did someone connect with a newer version of step 7 safety? any ideas?
