I'm working on developing a DeviceNet product, and I've afeeling I'm in deep trouble when reading the DeviceNet spec. In one section the authors refer to "8-bit octets", "16-bitoctets", and "N*8-bit octets".WTF?The word "octet" was introduced to mean a chunk of _exactly_ 8bits so that the word "byte" could denote a architecturedependant chunk containing a quantity of bits other t...

Hello ,i am developing an application on the Digital IO control, and i amimplementing a DiscreteInputPoint and DiscreteOutputPoint objects inthe devicenet stack .i have a confusion, that is what will be thecommands sent by a master to a specific DiscreteInputPoint .To put it neatly have a DiscreteinputPoint object which shallimplements GetAttibuteSingle function .if the master wants to...

Dear sir(Note to Mr Kevin Kramb:-sir i have followed your previous replies andi didnot get chance to thank you. thanks for you previous replies theyhelped me a lot ) I have been working on IO control application. i have a doubtregarding POLL IO messages .i have a 4 in and 4 out Devicenet IOmodule . I wanted to implement the Poll support. i am not able todecide what will be the da...

Are there any recommendations for 8051 DeviceNet driver source codefor a slave device? We are presently using Silicon Labs 8051 and theKeil compiler and tools. Silicon labs had a link to a supplier butthey are no longer support the Silicon Labs 8051 for some reason. Idon't mind paying for quality.Thanks,Peter Nachtwey

Dear allI am implementing Devicenet slave device, in which I want to use aPOLL command but I am stuck with the expected_packet_rate in POLL.what should be the default value of it .why should I configure expected_packet_rate in POLL because in POLLthe slave will respond to master command and there is no specificchance that master will request every time after a specific interval.mas...

Does anybody know if there is a demo board available for thePIC18F458? Any specific one that you might want to recommend? I sawa couple on Microchips website, and they didn't look like exactly whatI'm looking for. I need to implement a group 2 slave for DeviceNet,using CAN.Thanks,Chris

Hello I am trying to retrive a revision number of a Prism (positionsensor)(CutlerHammer make), and i am using netview to see the networkon SST master Card (CutlerHammer) .i am sending a 0E(getattribsingle)05(connection)00(instance) 01(attributeId)this gives me an error as Arrrtibute not supported .why this is so i think i am doing right since revision is a class attribute i should...

no doubt this is a FAQ oft beat to death, but, assuming one wanted to control a network of about 10 i/o modules each with maybe 100 i/o digital/analog points, at maybe a 100Hzmaximum rate (e.g. an automatic industrial processing machine of some kind) ...which control network would be, ahem, for lack of a better word, 'best'?(i.e. in terms of price/node, support, ease of development...
