24 C. COMMUNICAIONS & GEING SARED C.. Serial interface Communicating with the DAS 7. digitizer is carried out via the RS4/RS485 port. he data format is the familiar 8/N/ structure (8 data bits, no parity, stop bit). Available baud rates via the RS4/RS485 port are as follows: 9.600, 9.00, , or 5.00 baud. RS4 Connection using a 4 wire technique. Point-to-Point connection, i.e. no bus communication possible. Half duplex setup (DX=0). RS485 Connection using - or 4-wire techniques. Multi-drop connection possible, up to 3 DAS 7.. Half or Full Duplex (DX=0 or DX=) possible. (RS3) Select a RS485/RS3 converter. C.. Command Language he command set of the DAS 7. series is based on a simple ASCII format ( capital letters). his enables the user to setup the device, get results or check parameters. Example: DAS 7. with the address or channel number is connected via the RS 485 port to a bus system. You want to get the net weight. In this manual _ means space & means enter (CR/LF) Master (PC / PLC) sends Slave (DAS 7.) responds Status OP_ open device # OK device # ready GN N+3.45 get Net weigh Net weight with algebraic sign / comma he command OP_ opens the communication channel to DAS 7. device #. Now device # acknowledges that it is active and responds to any commands on the bus. Communication with device # will be closed by another OP command (for another device on the bus e.g. OP_5) or by the command CL_. Each OP_X command implies a CL command to all other devices on the bus except device #X. his makes the address structures easier and the system performance improves. Page 4 Manual DAS 7.

40 C.4.6 Set Zero/are and Reset Zero/are Commands SZ, RZ, S, R he following commands allow you to set and reset zero and tare values. he zero set during calibration remains the true zero but new current zero can be set using the SZ command. If the SZ command is issued and accepted then all weight values will then be based on the new current zero. Please remember that zero value will be subject to the Zero tracking function if enabled. If the weight signal is not stable (as defined by the No motion range NR and the No motion time N) then both the set zero SZ and set tare S commands will be disabled. Also the Set Zero SZ command is not allowed if the new zero value required and the calibration zero differ by more than %ofthecmvalue (maximum allowable value). See chapter 8 Legal for trade applications. SZ Set Zero his command sets a new current zero which is then the basis of all weight values until further updated by the zero tracking function, another SZ command or the reset zero command RZ. he SZ command will fail (DAS 7. responds with ERR) if the new current zero is more than % (of the CM value) higher or lower than the true zero set during calibration. he SZ command will also fail if the weight signal is not stable as defined by the No motion range (NR) and the No motion time (N). If the weight signal is stable, the response to the IS command (Device Status) will show the signal stable bit active and the SZ command will be accepted (OK). If the signal stable bit is not active, the SZ command will be rejected and the DAS 7. will respond with ERR (error). SZ OK Set zero performed he SZ command is issued without any parameters and will return either the OK or ERR response. If the SZ command is accepted the DAS 7. responds with OK and the zero action performed bit of the device status (IS) response will be active. If the command is acknowledged by the DAS 7. with OK, the status bit for Zero (request IS) is set to. A renewed SZ command or the reset zero command [ RZ ] changes the current zero point. he command is not implemented, if the current measured value is more than ±% of the maximum display value [ CM ] of calibrated zero point [ CZ ]. DAS 7. response is ERR (error). RZ Reset Zero Point his command cancels the SZ command and the zero reading reverts to that set by the CZ command during calibration. RZ OK Zero point CZ active again he DAS 7. responds to the RZ command with either OK or ERR. If OK is returned then the zero action performed bit in the Device Status (IS) response will be set to 0. Page 40 Manual DAS 7.

41 S Set are his command will activate the net weighing function by storing the current weight value as a tare. he weight signal must be stable within the limits set by NR (No Motion Range) and N (No Motion ime) commands for the signal stable bit to be active and set tare command to be accepted. S OK are performed If the weight signal is stable, the response to the IS command (Device Status) will show the signal stable bit active and the S command will be accepted (OK). If the signal stable bit is not active, the S command will be rejected and the DAS 7. will respond with ERR (error) R Reset are he weighing signal returns to gross mode. R OK are deactivated he DAS 7. responds to the R command with either OK or ERR. If OK is returned then the tare active bit in the Device Status (IS) response will be set to 0. Manual DAS 7. Page 4

46 C.4.9 Commands for external I/O control IN, IO, OM, AI he DAS 7. has 3 independent logic inputs and 3 independent logic outputs. hese inputs and outputs can be configured and controlled completely. he logic inputs can be read directly by the host application and the logic outputs can be fully controlled via the setpoint commands. he use of the setpoint commands (Sn, Hn, Pn, An) are explained in the following chapter 4.0. IN Read the status of the logic inputs his command reads the status of the logic inputs. IN IN:000 Input active IN IN:000 Input active IN IN:00 Input and active IN IN:000 Input 3 active he status response is in the form of a four digit code where 0 = false and = true (inputs are active high ), the least significant bit corresponding to Input etc. IO Read/Modify the status of the output channels his command reads and can modify the status of the logic outputs (if enabled by the OM command). he status response is in the form of a four digit code where 0 = false and = true (outputs are normally open, open drain MOSFEs), the least significant bit corresponding to Output etc. Request IO IO:000 Output active IO IO:000 Output active IO IO:00 Output and active IO IO:000 Output 3 active he status of the outputs can be changed by issuing the IO command with the appropriate 4 digit code e.g. IO 000 where in this example output will be activated (FE conducting). Please note that the status of the logic outputs is normally determined by the internal setpoints (see section 4.0) and therefore setting the logic output status using the IO commands is not allowed. Setting IO_000 OK Output active IO_000 OK Output active IO_00 OK Output and active IO_000 OK Output 3 active However, the OM command can be used to allow the status of the logic outputs to be set via the IO command or set their status directly by the host application. Factory default: IO=0 000 Page 46 Manual DAS 7.

47 OM Control of the logic outputs by the host application he logic outputs can be controlled by the host application (as opposed to the normal internal setpoints) if they are enabled by the IM command and the appropriate 4 digit code. Request OM OM:000 Enable Output OM OM:000 Enable Output OM OM:00 Enable Output and OM OM:000 Enable Output 3 A bit in the code enables the corresponding logic output to be controlled by the host application using the IO command. A 0 in the code leaves the corresponding logic output controlled by the internal setpoint. Logic output is again the least significant bit. Setting OM_000 OK Enable Output OM_000 OK Enable Output OM_00 OK Enable Output and OM_000 OK Enable Output 3 Note: When reading the status of the logic outputs using the IO command, the setpoint status will be returned regardless of the OM setting. Sending OM_0000 disables the external logic output control. Factory default: OM=0 000 AI Function of Logic Input, or 3 he DAS 7. has 3 independent logic inputs. hese inputs can be configured as follows: 0o: no function 0: acts as Zero button 0: acts as are button 03: acts as UP Arrow button 04: acts as DOWN Arrow button 05: starts the trigger function 06: displays the Average value 07: displays the Peak value 08: deletes the Peak value 09: displays the Hold value 0: displays the Peak to Peak value : displays the Valley value : disables the keyboard 3: stores the actual weight 4: tares display and deletes all other values like 08 AI_ I: no function AI 6 OK set display GA value AI_ I: display GA value Similarly to read or set the logic input or 3, use AI_ or AI_3 instead of AI_. Factory default: 0 Manual DAS 7. Page 47

48 C.4.0 Setpoint Commands - Sn, Hn, Pn, An he DAS 7. has 3 logic outputs where the status is dependent on the weight value (setpoint). Each logic output can be assigned an independent setpoint value (Sn) with a corresponding hysteresis (Hn), switch action (Pn) and base (An switch on the gross or the net weight). Sn Setpoint value for logic output, or 3 Request / Setting S S:+0500 setpoint S = 500 d S_03000 OK setpoint S= d Similarly to read or set the logic output or 3 setpoint, use S or S3 instead of S. H Hysteresis for logic output, or 3 Using the H command, the hysteresis on the setpoint value is set by the numeric value. Permitted values are H H:+0000 Hysteresis H = 00 d H_03000 OK Hysteresis H = d Pn Switch Logic for output, or 3 Using the P command, the switch characteristic setpoint S ON or OFF will be setup. Permitted values are0or. Example P P: switch logic P = 0 P_0000 OK switch logic P = Setpoint Hysteresis Switch logic Load Output open Output closed S = 000 kg H = 00 kg P = increasing 0 kg kg S = 000 kg H = 00 kg P = decreasing 000 kg kg S = 000 kg H = 00 kg P = 0 increasing kg 000 kg S = 000 kg H = 00 kg P = 0 decreasing kg 90 kg Example switch logic P= for setpoint (S) of 000 kg (lines &oftable above): When the weight is increasing between 0 kg and 00 kg the logic output is ON. Once the weight increases above 00 kg then the logic output is OFF. he logic output will come ON again when the weight value drops below 000 kg. Example switch logic P=0 for setpoint (S) of 000 kg (lines 3 & 4 of table above): When the weight is increasing between 0 kg and 999 kg the logic output is OFF. Once the weight increases above 999 kg then the logic output is ON. he logic output will switch OFF again when the weight value drops below 900 kg. Page 48 Manual DAS 7.

49 A Request / Set the Base for logic output, or 3 he A command defines the Base on which the setpoint value acts. If A is set to 0 then setpoint acts on the unfiltered gross weight. If A is set to then setpoint acts on the unfiltered net weight. A = 0 A = A = A = 3 A = 4 A = 5 A = 6 Not filtered gross weight Not filtered net weight Peak value Average value Hold value Peak to Peak value Valley value A = 7 Error message for ERROR 4/5 A = 8 Request / Set Base for logic output Output diabled A Allocation gross weight A_ OK Allocation net weight Similarly to read or set the logic output /3 Base, use A/A3 instead of A.

55 C.6 USE IN APPROVED APPLICAIONS (only as information) he term approved applies whenever the weighing application is intended to be used for legal-for-trade weighing - that is, money will change hands according to the weight result. Such applications are bound by the legal metrology regulations of the relevant governments around the World, but most countries will comply with either the relevant EN s (Euro Norms) or the relevant OIML (Organisation Internationale de Metrologie Legale) recommendations. he LDU 78. (e.g.) has been approved as a component for use in weighing systems according to OIML recommendation R76, the highest performance level approved being Class III, 5000 division. he approval Authority was the Danish Electronics, Light & Acoustics (DELA), and the approval certificate number was DK099-R Revision, dated his approval will allow the use in approved weighing systems throughout Europe, and in many other countries of the World. o achieve approval on a particular application, it will be necessary to satisfy the relevant Governmental rading Standards Authority that the requirements of the various rules and regulations have been satisfied. his task is greatly simplified if the key components of the weighing system, namely the load cells and the weighing indicator or digitizer, are already approved as components. Usually, a discussion with the Weighing Equipment Approvals Officers at the relevant National Weights & Measures Office will then reveal the extent of any pattern testing that may be necessary to ensure compliance. Restrictions upon usage when in Approved applications A number of performance restrictions must come into force. hese restrictions are the number of display divisions, which become limited to 5000 divisions, and the sensitivity per display division, which becomes 0.7 V per division. Once installed in the application, an approved application will require stamping by an Officer of the relevant Governmental rading Standards Department. his certifies the equipment or system as being in accordance to the relevant regulations and within calibration limits. he raceable Access Code (AC) he user software must then provide a guard against improper access of the calibration commands (see the Calibration Commands section). he DAS 7. digitizer features the raceable Access Code or AC method of controlling the access to the calibration commands group. his means that a code is maintained within the device, and is incremented whenever any change to any of the calibration commands is saved. When performing the stamping test, the rading Standards Officer will make a note of the AC, and advise the user that any change to this code which occurs prior to the regular re-inspection by the rading Standards Office, will result in legal prosecution of the user. he user software is required as a condition of approval, to make the AC available to the weight display indicator or console, on demand.
