  1. Connectors • on CIP and • on DeviceNet Buscoupler 24V, GND - twisted pair CAN Low , CAN High - twisted pair DeviceNet Hardware WAGO - Connectors CIP shield CAN high (wh) CAN low (bl) GND (bk) Microstyle Connector, 5 Pin (refer to MV-Controller User‘s Guide for pinout) 24V (rd) Plastiknose for allingning the connector is very sensitiv !! The DeviceNet can have a maximum of 64 Nodes in total (AWC is node 0 and Master by default) On DeviceNet nodes adjust MACID, BAUDRATE by DIP switches 120 Ohm resistor between CAN high and CAN low I/O 120Ohm Connect 24V and Ground to Buscoupler and CIP ! (see overview on next page) I/O On AWC adjust LOCAL_ID statement using "config_c": MACID 0..63, BAUDRATE 125kBaud, 250kBaud, or 500kBaud I/O AWC / CIP Master (MACID:default 0)

  2. DeviceNet Hardware WAGO - Overview Buscoupler 2 Input- Modules 2 Output- Modules End module 24V and Ground supply for DeviceNet-Master (AWC / CIP) 24V and Ground available on all modules DIP-switches for MACID and BAUDrate * 120 Ohm resistor between CANHigh und CAN Low 24V and Ground supply for DeviceNet-Bus and Bridge to 24V and GND trails (going through all modules) * There are modules for galvanic separation, that allow to apply different voltages for switching.

  3. DeviceNet Software (Monitor-Commands) Monitorcommand : .devicenet check the Devicenet-Status, (compare to Net-Command for TCP/IP) OK: D13 Siemens (Infineon) Germany „new system“- no DeviceNet configured, yet. faulty: E12 from Taiwan Powerup problem: The DeviceNet Chip on the AWC (s.o.) isn‘t initialized in a controlled manner during system bootup. The DeviceNet Buscoupler may go into error condition for that reason (red BUS OFF LED on buscoupler is going on). Recommendation: Not all DeviceNet components supply an automatic Error-Reset that re-initialize communication after 20 sec. Switch on 24V-voltage for DeviceNet logic by relais after bootup of the AWC. Monitorcommand / V+Instruction : (undocumented) .dn.restart Reset of DeviceNet communication (takes around 20 sec) New since V+ 13.0 G3, 13.1 J6, 13.1 S2, 13.1 D3 and 14.0 G2 a counter for „Missed packets“. Accessable from V+ with: FCMND(lun,761)““,$input can.lost = INTB($input, 11)

  4. DeviceNet configuration - SCAN THE DEVICENET Scan the DeviceNet: Input size, Output size: In general those two values represent the numbers of Input or Output BYTES available on a DN node with a certain MAC ID. Each Input or Output module of the WAGO hardware (see overview) contains four Inputs / Outputs (= 4 Bit). Values for Input and Output size are rounded to the next full Byte. Attention: The scan result for Input size is missleading, as the buscoupler is marked as one additional Input-byte. Memorize these informations, as they are needed for subsequent DeviceNet configurations. Set by DIP switches on Buscoupler Example: Wago Node with 3 Input- and 5 Output-modules: (In total 12 Inputs and 20 Outputs) Input size = 2 Bytes (rounded) + 1 Byte (coupler) = 3 Output size = 3 Bytes (rounded) If problems occur during scan, check if 24V/GND is connected to the DeviceNet logic (connector on Buscoupler) AND to the DNMaster on the AWC (connector on CIP)

  5. DeviceNet configuration - LOCAL, MACID In case of this error, the V+ errorhandling could execute the DN.RESTART instruction (only for DN components w/ automatic error reset), or switch off and on the 24V suply for the DeviceNet logic. Address (MACID) of DeviceNet Master (AWC) default=0 DeviceNet scanner speed. MUST meet the DIP switch settings of all DeviceNet nodes. If a DeviceNet Node has Inputs that are relevant for the system safety, it can be told to force a High Power Disable with this statement.. Insert results from previous DN scan here

  6. DeviceNet configuration - I/OMapping Output-Mapping (mapping nr. 1 ): 2 x 4 Outputs 2 x 4 Inputs On DeviceNet node #1 (MACID 1), starting from Byte#1, first bit, define the next eight outputs (33 ... 40)** ** the IO mapping can be split (even within a single module). 1070 1069 1066 1065 33 34 37 Input-Mapping (mapping nr. 2 ): 38 On DeviceNet node #1 (MACID 1), starting from Data-Byte#1 *, first bit, define the next eight inputs (1065...1072)** 24V GND 1072 1071 1068 1067 35 36 *the /BYTE part of an input-mapping statement only refers to the Data-Bytes (the additional Inputbyte of the Buscoupler, shown during the scan, is disregarded here !) 39 40
