Dear All,   Hello everyone! Been a few years since posting on this forum but I have a question and though that one of you might be able to help. We have a Siemens 1200 on a ship and every now and again the PLC goes into STOP mode. I'm not sure the reason why it does this but I believe it may be due to a power outage or power surge, maybe it think that a card is not present or something. In any case, it means I have to go and visit the ship, plug in my TIA Portal V12, go to online and click RUN CPU. My question, is, is there a way to program the PLC so that under no circumstance the CPU will go into STOP mode? Can I maybe use a OB to force it to always stay in RUN mode even if it sees hardware errors? Thanks for any input. Cheers, Ben  

Thanks Bryll, will do!   Thanks for the advice.   Cheers,   Ben

Hi, thanks for the comments. This was all I saved when I was on site last week. Does this help? (attached)

Hi all. This is my first post here. I am trying to display a number in a register with at least 10 decimal places as a floating point number. The maximum dp's I can get is 8 (eg: 0.12345679 - as shown in the picture). The plc I am using is a Logix5572. I think I may need a 64 bit register to do this but not sure. I don't know if ths is a very trival task, or if it is even possible. Any advice on how to do this would be very useful. Many thanks in advance. Ben
