_GS_ Posted January 12, 2012 Report Share Posted January 12, 2012 Hello, I'm new on this forum and I haven't to much experiences with V350 programming. My first little program doesn't works :-(. After buliding project I receive information: Error type 705: The defined hardware configuration does not support immediate input 6 Error type 705: The defined hardware configuration does not support immediate input 7 Error type 705: The defined hardware configuration does not support immediate input 8 Error type 705: The defined hardware configuration does not support immediate input 9 Data sheet of V350-35-R2 describes: - 12pnp/npn Digital inputs (including: 2 Analog and 3HSC/Shaft encoder), - 6 Relay Outputs. I want to use 10 pnp digital, 2 analog inputs and all outputs. Is anyone who may help me? Best Regards for all Grzegorz Link to comment Share on other sites More sharing options...
AlexUT Posted January 12, 2012 Report Share Posted January 12, 2012 Hi, About how Ladder and PLC program works: PLC contineously scan ladder code from up to down and from left to right. All Inputs are read before the start of the first net processing. All Outputs are updated after the last net processing. So at the time you wants to use some Input result - it is already known. Immediate Read operation allowed only for High Speed Inputs. In your case these inputs are 0 to 5. So there are right messages for inputs 6 and up. Now question - why you use Immediate Read? Do you really need this in your first project? Link to comment Share on other sites More sharing options...
_GS_ Posted January 12, 2012 Author Report Share Posted January 12, 2012 Hi, .... snip Now question - why you use Immediate Read? Do you really need this in your first project? I try build simple application with some external signals. User via little keyboard controls few relays. All may to work with differents mode of operations. The modes control V350. Keyboard is connected to I0 - I109. To I10/an0 and I11/an1 I've connected analog siglals from pressure sensors. I build slow time changing system. I've used Immediate Read/Write to receive or send signals between V350 and world. Is this wrong? It will correct to use Direct Contact or Coil?

AlexUT Posted January 12, 2012 Report Share Posted January 12, 2012 Hi Grzegorz, In such a slow working system you really do not need to use Immediate Read/Write. Use direct Contacts and Coils to simplify program. Scan time of V350 is 3-7 mS, dependent of application size and other time consuming operations. B.R.
