2 Modules 2.5 Description of connections to the AS interface module SK TU1- / TU3-AS1 By means of the AS interface cable and the AS interface master the sensors and actuators are connected to the automation device via the AS interface module. To connect an SK TU1 / TU3-AS1 module to an AS interface network, special connecting accessories must be used. An AS interface cable with an M12 connector and open cable ends is required in order to connect to the Phoenix terminals of the SK TU1 / TU3-AS1.
NORDAC AS-Interface Manual 2.5.2 Connection of the AS interface AUX power supply The black cable is used for the power supply to the sensors. The AS interface supply cable is connected to the AUX 24V and AUX GND terminals. The corresponding connection terminals on the particular AS interface module are illustrated in Sections 2.1.2 / 2.2.2 / 2.3.2. The AS interface modules have multiple supply terminals. These terminals are interconnected internally.
2 Modules c) 2 Sensors: Use of a 5-wire M12 cable with open cable ends and wiring of the sensors according to the assignment of connections. As there is no standard system connection technology, the wiring must be carried out accordingly.
NORDAC AS-Interface Manual 2.6 Recommended AS interface accessory and connection components NOTE The components listed below or in this section should only be regarded as recommendations. For further information please refer to the particular manufacturer's information and data sheets. Please observe the manufacturer's information regarding installation and the corresponding installation guidelines.

NORDAC AS-Interface Manual M12 round connector for connecting sensors/actuators and options/slaves to the AS interface cable M12 x 1 round plug connectors are supplied and distributed by many manufacturers of industrial applications. When selecting the components, special attention should be paid to application-specific requirements, e.g. Type of connection, number of pins (4 or 5-pin) Plug and socket coding, straight or angled design etc.
3 Bus structure and topology 3 Bus structure and topology The AS interface network can be set up in any desired form. Linear, star, ring and tree structures are possible. An existing network can be expanded by further slaves at any time. For the sake of simplicity the standard slave application will mainly be described in this manual. Up to 31 standard slaves (i.e. a maximum of 124 binary sensors and 124 binary actuators) or 62 A/B slaves (i.e.
NORDAC AS-Interface Manual The AS interface system replaces the expensive parallel wiring of decentralised sensors (inputs) and actuators (outputs) with a few bits (1-4 bits). The AS interface options from Getriebebau NORD, which need to be supplied with an additional +24V DC supply (AUX, black cable connection) for the electrical components, can also be used as I/O expansions for customer-specific applications.
3 Bus structure and topology An additional bit is required in order to address an A/B slave. This bit is inserted into the reference data area, so that the content of the 4 data bits must be divided over 2 protocols, i.e. 2 transmission cycles. On the other hand, the response telegrams contain all 4 data bits, so that the telegrams from the slave to the master are completely updated after each order. Also, due to the extended address range, A/B slaves can only be accessed every 2nd cycle.
NORDAC AS-Interface Manual Power on Initialisation OK Configuration Parameter call up received Reset outputs In the "configuration" status the slave waits to be identified by the master and ultimately to be activated. This is performed by means of a command "Exchange parameters" After this the slave reverts to normal operation and responds to calls for data. A timeout function "watchdog" monitors the current data communication.
3 Bus structure and topology AS interface properties Topology free structure, i.e. linear, tree, star, spur branches etc. Medium for data + energy unshielded 2-wire AS interface cable (= yellow standard AS interface cable) AUX connection (black cable) Insulation piercing technology as per IEC 60352-6 AUX voltage according to PELV (IEC 60364-4-41) Length of bus cable max. 100 m (without repeater), can be extended to 300 m with a maximum of 2 repeaters Number of slaves max.
NORDAC AS-Interface Manual 3.2 Cable type A simple 2-wire cable with a cross section of 2 x 1.5mm² should be used for networking. It is recommended that the yellow profile cable is used. Due to the mechanical profile of the cable, each slave can be simply connected without danger of incorrect polarity. As the geometrically coded position of the wires is fixed and there is no obstruction from shielding, the slaves can be connected to the AS interface bus using simple insulation piercing components.

NORDAC AS-Interface Manual 5 Data transfer / Parameter-string transfer NOTE The information in Section 5 does not apply to the AS interface Technology Unit SK TU2-AS3 (A/B slave). (only necessary for extended functionality) The Parameter string transfer is available for the modules SK TUx-AS1 (Standard slaves, slave profile S-7.4). This extended functionality is implemented in the AS interface master according to the Complete Specification 2.1.
5 Data transfer / Parameter-string transfer 5.1 Read ID string (read from slave) Via the AS interface module, specific data from the frequency inverter can be read out by means of the Read ID string command. The information and values in the ID string will first be shown when the AS interface has recognised the frequency inverter.
NORDAC AS-Interface Manual 5.3 Read / Write parameter string (read from slave / write to slave) The parameterisation of the frequency inverter can be carried out and checked with the commands Read parameter string and Write parameter string. Information parameters can also be read out in the same way. For both reading and writing, the first two bytes in the parameter string are used as an index. Then the data content is transferred. The number of data words is restricted to 8 words (16 Byte).

5 Data transfer / Parameter-string transfer 5.4 Process data (PZD) 5.4.1 Status word (ZSW) In the inverter response telegram, in the area of the process data the status word (ZSW) is transferred as the first word. For example, the status word "Ready for switch-on" corresponds to 0B31(hex).
NORDAC AS-Interface Manual Deviations in the status word (ZSW) for SK 300E and SK 700/750E series devices With the above device types, the meanings of the two bits 10 and 13 in the status word deviate from the status word of the SK 500 E.
5 Data transfer / Parameter-string transfer 5.4.3 Actual value 2 and actual value 3 (IW2/3) It is possible to forward two more actual values to the controller if PPO type 2 or 4 is used for transfer. The actual value 2 (IW2) is transmitted in PZD4. The value to be transferred can be selected in P544 (actual bus value 2). Actual value 3 (IW3) can be transmitted in PDZ3 if actual value 1 is not a 32 Bit value. The value to be transferred can be selected in P545 (actual bus value 3).

5 Data transfer / Parameter-string transfer 5.5 Data transfer with USS reference data / Parameter range (PKW) (only necessary for extended functionality) The reference data (without telegram framework) correspond to the USS protocol. Using the PKW mechanism, parameter processing can be carried out in the cyclical data traffic. For this the master formulates an order and the inverter formulates the response to this.
NORDAC AS-Interface Manual The following table lists all the orders which can be transferred from the master to the inverter. The right-hand column contains the response, which is normally sent (response label positive). Only certain response labels are possible, depending on the order label. In case of error (response label negative) the inverter will always supply the value 7 in the response label (AK) to the master.
5 Data transfer / Parameter-string transfer Error messages if the order cannot be executed In the response label "Order cannot be executed" (AK = 7), then an error message is added to the parameter value (PWE2) of the inverter response. For the meanings of the values transferred, please refer to the following table. No.
NORDAC AS-Interface Manual 5.5.3 Parameter value (PWE) For each parameter, the transfer of the parameter value (PWE) is always as a word (16 Bit) or double word (32 Bit). Only one parameter value can be transferred in a telegram. A 32 bit parameter value comprises PWE1 (high value word) and PWE2 (low value word, 4th word). A 16 Bit parameter value is transferred in PWE2. For negative values the high word must be set to FFFF hex. Note: 32- Bit parameter values are only used with the posicon option.
6 Examples 6 Examples For information about AS interface data, e.g. identification code (ID Code), extended ID Codes 1 and 2 and the I/O configuration (I/O Code), please refer to Section 8. NORD AS-Interface modules are Standard-Slaves (exception: SK TU2-AS3 = A/B Slave) and are set with the slave address 0 at the factory. 6.1 Example based on a Siemens Master CP343-2P This example supports the user in the design and implementation of the AS interface application.
NORDAC AS-Interface Manual For this, the following FI parameters must be set as follows: P480 [01] Bus IO In Bit 0 1 = Enable right P480 [02] Bus IO In Bit 1 2 = Enable left P480 [03] Bus IO In Bit 2 8 = Parameter switch-over P480 [04] Bus IO In Bit 3 12 = Error acknowledgement P481 [01] Bus IO Out Bit 0 2 = Inverter operating P481 [02] Bus IO Out Bit 1 7 = Error P509 interface 0 = Control terminals or keyboard control P543 Bus actual value 1 12 = Bus IO Out Bits 0-7 P546 Bus setpoint 1 17
6 Examples 6.1.4 Data transfer of the sensor signal statuses to the AS-I master alone It is often the case that the signal statuses from photoelectric beam detectors, buttons or other field components have to be communicated to the AS i master via the two-conductor AS interface network. In the parameterisation of the available BUS IO bits, there is the possibility of transferring the signal statuses of sensors connected to the AS interface module or the IO sockets 1/2 to the ASi master.
NORDAC AS-Interface Manual 6.2.1 Read ID string The command number 42hex is to be entered into DB13.DBB4 and the slave address 1 into DB13.DBB5 in the transmission buffer of the command interface. After the command or the order from the AS interface has been completed without error (DONE = 1), the response date is displayed in the reception buffer. For the allocation of the individual status Bits, please refer to the information in Section 5.1.
6 Examples Data Byte in DB13 Value in hex Meaning / Note DBB4 40 Write the command number for the parameter string DBB5 01 Slave address DBB6 04 Number of parameter Bytes, 04hex DBB7 00 Byte 0: Index DBB8 54 Byte 1: Index, start-up time P102, parameter set 1 DBB9 03 Byte 2: parameter value, taking the resolution 0.01 into account DBB10 E8 Byte 3: parameter value, taking the resolution 0.01 into account With this, the start-up time in P102 for parameter set 1 is changed to 10.00s.
NORDAC AS-Interface Manual Example of reading direct parameters: In order to check whether the direct parameter has been correctly transferred, a plausibility check should be performed. For this, the corresponding index must be sent with the function Write Parameter. For the start-up time P102 in parameter set 1, this would be the Index 0054hex. Only the Index needs to be transferred, i.e. the number of parameter Bytes is 2.
6 Examples Example for the writing of a parameter (PKW data via USS protocol / Parameter string): For example, in order to set the release time of the brake P114 (parameter number PNU = 114 / 72hex) of the FI to 1 sec for parameter set 1, proceed as follows: • Select parameter label PKE (AK =1 for change parameter value (word) and parameter number PNU = 72hex) • Taking the internal resolution of the frequency inverter into account (0.01sec) => for 1 sec there must be a parameter value PWE of 1 / 0.
NORDAC AS-Interface Manual Example for the reading of a parameter (PKW data via USS protocol / Parameter string): In order to check whether the order has been correctly carried out and the new value of 1sec has been entered in parameter P114 for parameter set 1 in the inverter, the corresponding response label must be read out using the command Read Parameter String Data Byte in DB13 Value hex in Meaning / Note DBB4 41 Read the command number for the parameter string DBB5 01 Slave address The foll
6 Examples 6.4 AS interface as I/O expansion of the frequency inverter control terminals By means of the AS interface module the number of digital inputs and outputs on the frequency inverters or made available by the use of a customer interface can be expanded by 4 further inputs and two outputs. Via the 4 sensor inputs (Sensor Dig In / Bus IO In Bits 4 to 7) all functionalities specific to the frequency inverter can be assigned or parameterised via the parameter arrays in parameter P480.
