  1. ML1400 Solid LED Fault & Power, Blank Display

    AB Tech Support, Confirmed PLC Dead Possible Internal Short, Steve Stated PLC w/Current LED Status, Should Still have a Operating LCD Display, Due To Voltage Drop On DMM When ML1400 Pwr-Up Might Explain Blank LCD. PLC Has Seen Its Better Days/ Repair or Trash.   We Did Try Disconnecting Battery, Then Shorted Out Both Battery Leads On PLC To Drain Internal [Memory/Program] Capacitor, 5seconds, Can Leave Battery Disconnected, Try PLC Again. ML1400 Will Retain Program For Aprox 2 Weeks w/BAT-LO Condition. AB Tech Support 440 646-3223...end
  2. ML1400 Solid LED Fault & Power, Blank Display

    Evaluation:  The Acopian Pwr Supply, Power-On/Inrush DMM VDC MAX= 23.90, Normal=23.90Vdc                       2nd 24VDC Power Supply, SKYNET Electronics M# SNP-A129, [Parker Automation] Pwr-On/Inrush Max=23.87, Normal=23.84Vdc                      Same PLC Fault Condition, Going To Contact Allen Bradley Tech Support Today
  3. 1766-L32BXB Ser B FW 13 In Service 100% 1yr. w/Parker Automation Touchscreen/Ethernet Comm. Note: All Rockwell Software For ML1400 Ser B and ML1400 (Default) CH-0 (8-Pin Din) DF1 RS232, PC-COM1 Cable & Settings Are Same           When Working, Did Revisit RSLink/DF1/Auto-Config, STILL FAILS. PC Has True 9-DB Com-1, PC Device Mgr, COM-1 Set To           ML1400 Default Baud, ect, PC No Conflicts.  In All AB Software & Comm Is Not My Problem. Rockwell Software Registered To Me. AB Manual Ref: Hardware Failure  ( I Would Assume PLC Death/Brick) Discovered a Micrologix 1400 Backlight Life Is 50K Hrs Verses a EL Backlight Installed Is 2K Hrs. I Can Temp/Do w/o a Display For Now, RSLink, No Comm The PLC Power Supply Is a ACOPIAN VA24MT210, 24Vdc Regulated, DMM=23.75vdc, When Power Applied To ML1400 DMM=4.63vdc ML1400 POWER Solid Green, FAULT Solid Red, LCD Display Remains Blank. Can Anyone Else Confirm This PLC Current Status? FYI, AB Knowledge Base, Answer 37814/898272 Not Public, ML1400 Red Fault, Only Related Item Not View When Searched Thank You         Sempter-Fi
  4. PV800 HMI multiple position switch

  5. Hi, I Think I Might Have 1 Problem(s) w/MSG Logic, Never Used MSG's Before.  This Is a Home Training Project, To Get This Far Took Some Learning Curve.  HMI Requires w/Ethernet-ABEN (Allen Bradley Driver) MSG's, Bootp Not Supported w/ABEN Seach For ABEN Nothing/Maybe w/a Tech Connect Acct, Which Work No Longer Supports. Thanks To All For Viewing & Helping Already Established a DF1 RS232 Network w/ML1400 & HMI Works Perfect  Also a WiFi Only w/PC & ML1400-Working   Wanted To Attempt The Ethernet Network w/HMI-Ethernet/Uncharted Waters!

    Ken,              Thanks, Going For The 1747-UIC,  During My Internet Searching Never Ran Across a UIC & AIC+ Combo  Used For DH485 Multi-Nodes, Was Not Sure   If It Could Be Done, Thanks Again Ken,  Sempter-Fi     1973 Hollywood Marine 0351 1stMarDiv FMF, GITMO. Later & Thanks Again.  
  7. Forgot What Round This is, Still Have a Bleeding Nose, Going In, Trying To Establish DH485 Network, Please See Enclosed Attachment For Better Details, Seeking Guidance & Knowledge, Already Got a *** Beatin.    Senior Citizen In The Neighborhood,  Thank's.
