(see also switch set- tings) 1x16 position rotary-switch for selecting number of dupline ? channels in the range 8..128 (in steps of 8). the selected letter indicates the last channel group available on dupline ? . if e.g. h is selected, the 64 channels in groups a..h will be available. dip-switch (1) for selection of dupline ? operation mode. in "normal" mode, dupline ? oper- ates as a peer-to-peer system where the channel generator automatically establishes a connection between dupline ? inputs and dupline ? outputs which are coded to the same dupline ? address. if e.g. an input coded for b5 is activated, the output(s) coded for b5 will also be activated. consequent- ly a dupline ? output can either be activated through the out- put-data received on ethernet or by an active dupline ? input coded for the same dupline ? address. in "split i/o" mode, the dupline ? inputs and dupline ? outputs are created independently by the channel generator. if e.g. and input cod- ed for b5 is activated, the gateway will make the informa- tion available on ethernet (like in normal mode), but it will not automatically activate the dupline ? output(s) coded to b5. the dupline ? outputs are con- trolled exclusively through the output data received on ether- net. note: analink output as well as bcd multiplex data only work in split i/o mode. dip-switch (2) for selection of analog data. in off position only digital in/out data are transferred. to enable analog data-i/o handling this dip- switch must be on. dip-switch (3) for selection of analog input operation mode. when off the analog input data are read as analink. each channel from c1 to p8 is read as 8 bit analog data. when on the analog input data are con- sidered as 3 _ digit bcd multi- plexed data. the multiplex-con- trol (synchronization) are auto- matically set to operate on channels a1..a4, which then cannot be used for other pur- poses. wiring diagrams power supply 230 vac power supply 115 vac supply spec i fi ca tions power supply overvoltage cat. iii (iec 60664) rated operational voltage through term. 21, 22, 23 & 24 see wir ing diagram 230 230 vac 15% (iec 60038) 115 115 vac 15% (iec 60038) frequency 45 to 65 hz rated operational power 11 va rated impulse withstand voltage 230 4 kv 115 2.5 kv dielectric voltage supply - dupline ? 4 kvac (rms) supply - rs 485 4 kvac (rms) 21 19 210 1 2 3 4 311 412 513 614 715 816 29 22 30 23 31 24 32 25 33 26 34 27 35 28 36 dupline supply 115v p nn p 115v dupline settings 1234 on no. channels ethernet connector ip address leds status + d d
du line fieldbus installationbus specifications are subject to change without notice (21.08.2006) 3 dupline ? is a registered trademark. a product of the carlo gavazzi group g 3891 0052 dip-switch (4) for selection of analog output operation mode. when off the analog outputs are emitted as analink. when on the analog output-data are emitted as 3 _ digit multiplexed data, and channels a1..a4 will control the multiplex address- ing. note: change of dip-switch settings during operation, may cause reset of the gateway. dupline ? input data a part of the gateway input processor reads all the 128 dupline ? -channels as digital inputs (16 bytes) and another part reads the 112 channels (c1 to p8) as analog inputs. each analog value is represented as a 16 bit word with mbs as sign and 15 bits of magnitude. this results in a total of 224 bytes containing all analog input- data. since the sign of a valid dupline analog value is always positive, the range is 0..32767, where 32767 corresponds to the max analog input. it is up to the user to read the data in the correct area (digital or analog) according to the type of mod- ule (digital or analog) he has installed on a dupline address. all data are mapped with digital input bytes starting at relative address 00 followed by the analog data. see in/out data mapping. dupline ? output data a memory area of 16 bytes is available for control of the out- puts of the 128 dupline chan- nels. if normal mode is select- ed, the outputs can also be controlled from dupline trans- mitters (or-function). a memo- ry area of 224 bytes is available for control of the 112 analog output values. the data must be entered in the range 0..32767. the gateway will convert them to the right dupline format in accordance with the selected analog out- put operation mode. however ,analink output works only in split i/o mode. when analog transmission is selected it is important to write the value ffff hex (-32767 decimal) to all those of the 112 output addresses where no analog output is desired. otherwise the digital transmission will be dis- turbed. also, in case 3 _ digit bcd is selected, it should be noted that sending out analog values on one or more multiplex addresses on a double-group (e.g. c-d) will disable the use of this entire double-group for dig- ital transmission. however, bcd multiplex data also works only in split i/o mode. ip address information ip address the ip address is used to iden- tify each node on the tcp/ip network. therefore, each node on the network must have a unique ip address. ip address- es are written as four decimal integers (0-255) separated by periods, where each integer represents the binary value of one byte in the ip address. this is called dotted-decimal nota- tion. example: address 10000000 00001010 00000010 00011110 is written as 128.10.2.30 subnet mask the ip address is divided into three parts - net id, subnet id and host id. to separate the net id and the subnet id from the host id, a subnet mask is used. the subnet mask is a 32- bit binary pattern, where a set bit allocates a bit for network/subnet id, and a cleared bit allocates a bit for the host id. like the ip address, the subnet mask is commonly written in dotted-decimal nota- tion. example: to make the ip address 128.10.2.30 belong to subnet 128.10.2, the subnet mask shall be set to 255.255.255.0. subnet mask: 11111111 11111111 1111111 00000000 (255.255.255.0) net id /subnet id/host id important note: to be able to establish communication between two devices both devices must belong to the same subnet. if not, the com- munication must be done through a gateway. it is there- fore recommended to configure the module to the same subnet as your pc (if e.g. the pc has ip address 192.168.2.21, then the ip address of the dupline ethernet gateway must have an ip address 192.168.2.n , where n is a number in the range 1..255). ip address selection the module offers two ways to configure the ip-address: ? by using the dip switches in the front ? by using the arp-command from a pc using the configuration switch for selection of ip address the configuration switch pro- vides an easy way to configure the module for intranet use. the switch represents the binary value of the last byte in the ip address. if the switch is set to a value between 1-255 the mod- ule will use the settings described below. (if the switch- es are all in the off-position, corresponding to the value 0, then the gateway is set up to be configured using the arp- command from a pc.) ip address: 192.168.0.n subnet mask: 255.255.255.0 gateway address: 0.0.0.0 (no gateway set) the last byte (n) represents the binary value of the switches. subnet mask and gateway address settings are fixed to the above values when using the configuration switches. example: the switches are set to 00010100 (20 decimal) the ip address of the module will be set to 192.168.0.20 note: these settings can only be used on an intranet. this is because the ip address that is being set belongs to the private address set. using the address resolution protocol (arp) for selection of ip address the ip address can be config- ured (or changed during run- time) using the arp command from a pc. below is an exam- ple on how to change the ip address from a ms dos? win- dow (which is normally avail- able under "accessories" as "command prompt" in the win- dows programs menu). arp -s ping arp -d example: to set the ip address to 192.168.2.21 on a dupline eth- ernet gateway with mac address 00-30-11-02-10-da the following commands should be issued in the "command prompt" window: arp ?s 192.168.2.21 00-30-11- 02-10-da ping 192.168.2.21 arp ?d 192.168.2.21 the arp -s command will store the ip and mac addresses in the pc?s arp table. when the ping command is executed, the pc sends this information to the module using the mac address. the module detects that it was addressed with the correct mac address and adopts the ip address sent by the pc. (the arp -d com- mand is optional, but it removes the static route from the pc arp table). this method can be used to reconfigure modules that already has been configured, or even to reconfigure modules outside the host?s subnet. important note: the mac address is printed on a label on the bottom side of the module. important note: as the arp command automatically config- ures the subnet mask to 255.255.255.0, the first three bytes of the ip address must be the same as for the pc execut- ing the command. example: pc ? 192.168.2.67 module- 192.168.2.n (where n is a value between 1 and 254) mode of operation (cont.)
