  1. STAHL HMI outpur error: DB NOT AVAILABLE

    Hi, We have a MT-40-TTY/232 PROVICOM TYPE connected to our Siemens S5-95U. Recently we have been encountering an error message all the time: KOMMUNIKATION*** F E H L E R ***DB NICHT VORHANDEN     Apparently, in google translate it means DB NOT AVAILABLE. What does DB mean? Datablock? What could be the cause of this? Ever since this has happened, the HMI cannot output the real time sensor values and all of the keys we press on the HMI will not do anything at all. I am currently checking the output in the S5-95U using PG2000 and I've filtered the DB and they exist.  
  2. Hi, I've recently bought a generic RS232/TTY cable for Siemens S5 PLC. I also bought a RS232 -> USB converter to connect the cable to my laptop. My problem is that when I connect from S5 to Laptop and run PG2000, I cannot load anything from the PLC as the program gets stuck. I think nothing is being read from the converter. Please help.   Here is my setup: S5 Siemens PLC  http://i.imgur.com/kk3X7OU.jpg?1   RS232/TTY CABLE FOR S5 PLC  http://i.imgur.com/SbkD2g9.jpg?1   RS232 TO USB CONVERTER  http://i.imgur.com/Sy3C7hP.jpg?1   Thanks,
