  1. Hello, I am trying to flash an indicator light (Banner  K70LBGYRPQ ) every .5 seconds.  The PLC manual says 2.5A per channel.  The light uses roughly 113mA max current @ 24vdc.  I am using output 0 to do this (O:0/0).  I think I may have ruined the output by flashing the indicator light.  Has anyone ever experienced this before?  Is there a minimum pulse time for this PLC?  What do people normally do when wanting to flash an indicator light such as this?  This is not the first time I have seen this happen.   Thanks in advance!
  2. S7-200 failure?

    I'm new to this forum, and hope for help. We have a woodworking edgebanding machine (Cehisa, made in Spain) that stopped resetting (starting), a tech diagnosed a bad PLC because all its led's were flashing. Cehisa owns the software, so they are only source to upload the project. They quoted us $7500.00 + $100 shipping for a replacement (!!!). Problem is, even if we paid this , the replacement could also fail if it's an internal or external component problem. Siemens tech suggested a power supply issue possibly.  ( I put PLC in Stop, disconnected all outputs and lights stopped flashing. Can anyone suggest steps to meter test & "possibly" save the one we have? Spain, our US distributor, and our tech stopped communicating (they all say buying the new one is the answer). I have some electronics background, have and understand our machine's schematics but not versed on PLC's. Sorry for long-winded text.
