  1. Introduction à

  2. Qu’est-ce queDeviceNet?? En terme de réseautique, il s’agit d’une structure qui présente des avantages indéniables sur la structure traditionnelle Source-Destination. Il s’agit du modèle Producteur-Consommateur

  3. Exemple Source/Destination Une personne (“source”) dit a chaque personne (“destinations”) dans une salle l’heure du jour (data) • Les gens peuvent choisir d’ignorer l’information, mais il y a du temps et des efforts de perdu. • Le temps s’écoule au fur et a mesure que la “source” informe les “destinations”. • Le temps nécessaire pour informer tout le monde, varie selon le nombre de personnes présentes

  4. Exemple Producteur/Consommateur Une personne (“producteur”) dit a tout le monde (“consommateur”)en meme temps, l’heure du jour (“data”) • Tout le monde recoit l’information simultanément • Certaines personnes peuvent choisir de “consommer” l’information. (ex. en ajustant leur montres) • d’autres choisiront d’ignorer l’information • Tres efficace: cela prends le meme temps si 10 ou 100 personnes sont présentes dans la salle !

  5. Producteur/Consommateur Controller 2 Controller 1 HMI #1 #2 • message #1 • Position de référence du senseur vers Controller 1, Controller 2, et HMI • message #2 • Commande de vitesse du Controller 1 est émis vers les Drives 1, 2, & 3, et HMI • Moins efficace que le modele source/destination • requiet 7 messages vs. 2 Sensor Drive1 Drive2 Drive3

  31. Producer/Consumer Networks can support ALL three Connection Relationships • One-to-One • Multicast (One-to-Many) • Broadcast (One-to-All) • Mix and Match on the same network

  32. Producer/Consumer Networks can support ALL three Hierarchies • Master/Slave • Multimaster • Peer-to-Peer • Mix and Match on same network • Explicit and Implicit Message types

  33. Producer/Consumer Networks can support ALL three I/O Data Exchange Methods • Polling • Cyclic • Change-of-State (COS) • Mix and Match • Master/Slave, Multimaster, Peer-to-Peer • One-to-One, Multicast, or Broadcast

  34. Replacing Devices • Set node address, data rate (or Autobaud) • Configure device parameters • Connect device to system • Slave devices must pass electronic “key” • device type • manufacturer • part number • NEW! Auto Device-Replace ( ADR )

  35. Replacement Device Replacement Device Replacement Device #63 #63 #55 Auto Device Replace ( ADR ) • RSNetworx for DeviceNet software must be used to configure ADR feature. • ADR consists of two parts which are Node Recovery and Configuration Recovery. Node Recovery causes the node number of the replacement device to be automatically changed to the node number of the original device. This feature requires that the replacement device’s node number to modified over the DeviceNet network and its node number must be 63 to begin with. • Configuration Recovery will cause the replacement devices configuration to be made identical to the original device. The replacement device must be able to have its configuration written over the DeviceNet network. Configuration Recovery files are stored in the master scanner that is communicating with the original device by RSNetworx. • Electronic key of replacement device MUST match the original device exactly.

  39. 1770-KFD DETAILS

  40. 1770-KFD Fun Facts • The 1770-KFD is not a true RS232 to DeviceNet converter. The KFD is actually a buffering interface between the two networks. The RS232 device connected to the KFD is actually running a DeviceNet driver to communicate through the KFD. • 1770-KFD can NOT be put on-line unless at least one other node is also on the network. At least one other node must Ack the 1770-KFD Dup Mac Check. • The RS232 led on the KFD must blink when there is correct RS232 communication to the KFD. If not, then there is some configuration conflict in the computer that keeps the COM port on the computer from being used for the KFD. • 1770-KFD firmware is NVS Flash Tool upgradable. • If the KFD is connected to a network that has a 24VDC power supply attached, the use of an AC adapter connected to the jack on the KFD is NOT necessary. • An AC adapter, connected to the KFD, can source 60 ma of DC current for point-to-point connections to devices. • 1770-KFD contains a built in terminating resistor for point to point use.

  41. 1784-PCD PCMCIA DeviceNet Interface Card

  42. DeviceNet PCMCIA Interface(1784-PCD or 1784-PCDS) • PCMCIA card for PC connectivity to DeviceNet • Use PC to configure devices, monitor data, or perform simple maintenance functions • Type II compatible • Autobaud capable • Cabling scheme makes use of 1770-KFD cable options • Operating system drivers for Windows 3.x, Windows 95/98 and NT • Works with DeviceNet Manager and RSNetworx for DeviceNet software

  43. FlexI/O DETAILS

  44. 1794-ADN FlexI/O Fun Facts • Node Number is set via pushwheels on the 1794-ADN adapter. • Baud rate is handled via autobaud automatically by the 1794-ADN. • Current firmware revision is V2.01 as of 3/25/97. This also handles Change of State and Cyclic messaging. • Firmware is flash upgrade-able over the DeviceNet network using the NVS update tool on a PC. • When fresh out of the box a 1794-ADN will actively read what modules are in its rack on every powerup. It will use the default sizes shown in the following slides for each module contained in its rack to determine its Rx and Tx size. However, as soon as a specific configuration is stored to the 1794-ADN using the FlexI/O tool in RSNetworx or DeviceNet Manager, the 1794-ADN will lock in that configuration. The 1794-ADN will not automatically scan the rack anymore and will error if the rack configuration doesn’t match what it expects. The configuration is stored in the 1794-ADN and if the ADN goes bad. Someone will have to download the configuration to the replacement ADN before it will work the same as the original one. This complicates module replacement a lot. To clear out a configuration in an ADN and go back to “Fresh Out of the Box Mode” select the Clear Memory feature in the FlexI/O configuration tool in the RSNetworx or DeviceNet Manager. Note: Clear Memory will not operate if a network master is scanning the 1794-ADN at the same time. Disconnect the master from the network or disable scan list entry for the FlexI/O in the master before attempting a Clear Memory.

  45. 1794-ADN FlexI/O Fun Facts ( Continued ) • Do NOT supply power to the 1794-ADN adapter from the network 24 VDC power, as tempting as it looks. The 1794-ADN and other FlexI/O modules draw a lot of power ( up to 400ma ) and you could run out of current quickly or get bitten by Common Mode Voltage at longer distances. • 1794-ADN User Manual is Publication 1794-6.5.5. This manual shows how to configure the ADN and shows data sizes for most FlexI/O modules. • Be careful when assembling the 1794 Terminal Bases to the 1794-ADN adapter, as the pins in the side of the ADN and Terminal Bases are fragile and bend over easily causing erratic operation in the FlexI/O rack. A good way to determine if a pin is bent over is to remove each module from the FlexI/O rack and note if the network led blinks red until the module is replaced. This is desirable behavior and if the led does not blink upon module removal, then a pin is bent over. • Series B hardware is electrically identical to Series A except for a few cosmetic differences. Series B Phoenix connector has jack screws and there is a 3rd led to show power on the module. • UCMM Capable Device
