[?]: S7-200+TD-200 problem

Post by MABPIK »

Have problem with 224XP connected to TD200 - "No parameter block", while in status chart I see that all VB and VW responsible for configuration match original (TD DATA 0) before download, it starts from VB0 and parameter block adress at panel is also set to 0. What else can be done. URGENT

Smells like it is an TD problem. Check the TD settings (MPI address, V memory, etc...)
Otherwise, check your cabling. Do you use Profibus cable? Maybe PLC & TD are far away and you have EM interference. Try to ground the cable properly.
Usually it's a communication problem, it is rare to have faulty hardware, but you should also check your hardware.

Or maybe you have uncheked sending of datablock in communication options.
