DeviceNet Modules, Series 90-30, Manual, GFK-2196

2DeviceNet Cable for the Series 90-30 ModulesSeries 90-30 DeviceNet modules can be used with the either DeviceNet thick cable or thin cable.Thick cable permits greater cable lengths and higher current levels. Generally, thick cable is usedfor the trunk cable. Thin cable is normally used for shorter distances and is suitable for drop cablesand for installations where more cable flexibility is needed.Both thick cable and thin cable are 5-wire, multi-conductor copper cable. Two wires form atransmission line for network communications. A second pair transmits network power. The fifthconductor forms an electromagnetic shield. Most cables have color coded leads which correspondto the color coding on the terminals on the Series90-30 DeviceNet modules.Cable and Network SpecificationsThick Cable General SpecificationsThin Cable General SpecificationsTwo shielded pairs - Common axis with drain wire in centerOverall braid shield - 65% coverage; 36 AWG or 0.12mm tinned Cubraid minimum (individually tinned)Drain wire- #18 Copper min.; 19 strands minimum (individually tinned)Outside diameter - 0.410 inches (min) to 0.490 inches (max.) roundness- radius delta to be within 15% of 0.5 O.D.Two shielded pairs - Common axis with drain wire in centerOverall braid shield - 65% coverage; 36 AWG or 0.12mm tinned Cubraid minimum (individually tinned)Drain wire - #22 Copper; 19 strands minimum (individually tinned)Outside diameter - 0.240 inches (min.) to 0.280 inches (max.)roundness - radius delta to be within 20% of 0.5 O.D.Network TopologyBus with limited branching (trunkline/dropline)RedundancyNot SupportedNetwork Power for Node devices Nominal 24 VDC ±4%Allowed Nodes (Bridging excluded)Data Packet SizeDuplicate Address DetectionError Detection / Correction64 nodes0-8 bytes with allowance for message fragmentationAddresses verified at power-upCRC - retransmission of message if validity not acknowledged byrecipientBus Connector Pin AssignmentsThe DeviceNet connector on a Series 90-30 DeviceNet module has five color-coded screw-clampterminals. The connector provides bus continuity; it can be removed from the module withoutdisrupting bus operation.V+CAN_HSHIELDCAN_LV-Signal Pin Wire ColorV+ 5 RedCAN_H 4 WhiteShield 3 BareCAN_L 2 BlueV- 1 BlackGFK-2196 Chapter 2 Installation 2-3
