Page 52 O units, communication port connections and programming port connection. Power supply wiring Although the ADAM-5511 systems are designed for a standard industrial unregulated 24 V power supply, they accept any power unit that supplies within the range of +10 to +30 V .
Page 53 I/O modules wiring The system uses a plug-in screw terminal block for the interface between I/O modules and field devices. The following information must be considered when connecting electrical devices to I/O mod- ules. 1. The terminal block accepts wires from 0.5 mm to 2.5 mm. 2.
Page 54 Port connection The ADAM-5511 has three communications ports. These ports allow you to program, configure, monitor, and integrate ADAM-4000 modules as remote I/O. COM1: This is an RS-232 interface and only uses TX, RX, and GND signals. The pin assignment of the cross over cable is as follows:...
Page 55 COM2: The COM2 port is dedicated as an RS-485 interface. Screw terminals DATA- and DATA+ are used for making the COM2 RS-485 connections. Users have to prepare an ADAM-4520 RS232/485 converter for the linkage with PC. COM3: This is a spare RS-232 port for advanced users which require more than two ports in the system.
Page 56 There are four LEDs on the ADAM-5511 front panel. The LED’s indicate ADAM-5511’s operating status, as explained below: (1) PWR: power indicator. This LED is on when the ADAM-5511 is powered on. (2) RUN: program execution indicator. This LED is regularly blinks whenever the ADAM-5511 is executing a program.
Page 58 Analog input modules use an A/D converter to convert sensor voltage, current, thermocouple or RTD signals into digital data. The digital data is then translated into engineering units. When prompted by the host computer, the data is sent through a standard RS-485 interface.

The module protects your equipment from ground loops and power surges by providing opto- isolation of the D/A output and transformer based isolation up to 500 The slew rate is defined as the slope indicated the ascending or descending rate per second of the analog output from the present to...
Page 75 Analog input/output modules are calibrated when you receive them. However, calibration is sometimes required. No screwdriver is neces- sary because calibration is done in software with calibration parame- ters stored in the ADAM-5000 analog I/O module‘s onboard EEPROM. The ADAM-5510 system comes with the ADAM utility software that supports calibration of analog input and analog output.
Page 76 4. Execute the Zero Calibration command (also called the Offset Calibration command). This is also done with the ADAM utility software. (See the “Zero Calibration” option in the Calibration sub- menu of the ADAM utility software.) 5. Execute the Span Calibration command. This can be done with the ADAM utility software.

Page 79 (1) Note: You can substitute 2.5 V for 20 mA if you remove the current conversion resistor for that channel. Howev- er, the calibration accuracy will be limited to 0.1% due to the resistor's tolerance.
Page 80 The output current of analog output modules can be calibrated by using a low calibration value and a high calibration value. The analog output modules can be configured for one of two ranges: 0-20 mA and 4-20 mA. Since the low limit of the 0-20 mA range (0 mA) is internally an absolute reference (no power or immeasurably small power), just two levels are needed for calibration: 4 mA and 20 mA.
Page 81 5. Check the actual output value at the modules terminals. If this does not equal 4 mA, use the "Trim" option in the "Calibrate"sub- menu to change the actual output. Trim the module until the mA meter indicates exactly 4 mA, or in case of a voltage meter with shunt resistor, the meter indicates exactly 1 V.
Page 84 The ADAM-5051 provides sixteen digital input channels. The ADAM- 5510 can use the module’s digital inputs to determine the state of limit or safety switches or to receive remote digital signals.
Page 85 Ω...
Page 86 The ADAM-5052 provides eight fully independent isolated channels. All have 5000 V isolation to prevent ground loop effects and to prevent damage from power surges on the input lines.
Page 87 Ω The ADAM-5056 features sixteen digital output channels. The digital outputs are open-collector transistor switches that you can control from the ADAM-5510. You also can use the switches to control solid-state relays.

Page 92 ADAM-5080 is a 4-channel counter/frequency module designed to be implemented within the following Advantech ADAM-5000 series main units: ADAM-5000/485 (with firmware Version A2.3 or above) ADAM-5510 (with library Version V1.00 or above) ADAM-5510/P31 (with I/O driver Version V1.00 or above) Please make sure that the ADAM-5080 counter/frequency module is properly inserted into the compatible main units.
Page 93 selected, it means the Alarm status will be "latched" whenever the alarm being triggered. Once the alarm status being "latched," it will thereafter stay in that triggered state. Users will have to issue a "Clear Alarm Status" command to return the "latched" alarm status back to normal.
Page 94 Users can select Bi-direction, Up/Down Counter or Frequency option as shown in Figure 4. Note: All four channels of ADAM-5080 will operate simulta- neously in the mode you have selected. i.e. If you switch the ADAM-5080 to Counter Mode, all four channels will operate in Counter Mode.
Page 95 The Up/Down Counter Function offers two types of counting: Up Couting (increasingly) and Down Counting (decreasingly). Up Counting : when C0A+ and C0A- sense any input signals, the counter counts up. Down Counting : when C0B+ and C0B- sense any input signals, the counter counts down.
Page 96 Up Counting : when the input signal is within logic level "1", the counter value increases. Down Counting : when the input signal is within logic level "0", the counter value decreases. Note: If users select TTL mode and don't connect C0B+ C0B-, the counter value will increase.
Page 97 According to your application purposes, you can run the utility program to set different limit values for High/Low Alarm. In oder to utilize the alarm function, users have to set a high-alarm limit value and/or a low alarm limit value, and a initial value to fulfill the requirements for a basic alarm setting.
Page 99 Overflow value is the number of times the counter value exceeds the Max/Min values you specified. When the counter value exceeds Maximum value, the overflow value increases; When the counter value goes under Minimum value, the overflow value decreases. Besides, when the counter value runs beyond the range of Max/Min value, it will continue counting from the initial value.
Page 100 If users want to use Digital Output function, ADAM utility is available for setting specifically which module, channel or slot to receive the alarm signals. 1: High Alarm State--Set Alarm state to "Latch" or "Disable". 2: High Alarm Limt--Set Alarm limit from 0 to 4,294,967,295. 3: High Alarm Output Mode--Enable or Disable D.O.
Page 101 According to your need, you can select either TTL or Isolated Input Level by setting the configuration for the jumpers. Select the proper jumper settings for either TTL or Isolated Input according to Figure 4-47. Please note that you must configure all six jumpers to the correct configuration for proper function.

Page 137 Step 3. System Organization and Program Download Set up the system as figure 5-27 When remote I/O function applied in the application, there must be two ADAM-4520 in addition. One for PC monitoring and one for remote I/O network.
Page 138 Run ADAM-5511 Windows Utility and download the executive program with remote I/O function. Run the executive program, then click the specific 5511 again for search ADAM-4000 module.
Page 139 ADAM-5511 Utility will not detect ADAM-4000 module automatically before download the program with remote I/O and restart ADAM-5511. ADAM-5511 designed as a standard Modbus product and could be integrated with HMI via simple method. Here is an integration example for ADAM-5511 and Fix 6.0 HMI software.
Page 140 Step 2. I/O Module Address Setting Before integrating ADAM I/O Module into the database of HMI software, please refer the table as below to map ADAM-4000/5000 I/O address. Analog type of ADAM-5000 I/O module: Slot Position Address 40001-40008 40009-40016 40017-40024 40025-40032 For example, if there is a ADAM-5024 (4-channel AO Module) in slot 2, the address of this module should be 40017~40020.
Page 141 Analog type of ADAM-4000 I/O module: Node Number Address 41001-41008 41009-41016 41017-41024 41025-41032 41249-41256 Digital type of ADAM-4000 I/O module: Node Number Address 01001-01016 01017-01032 01033-01048 01049-01060 01497-01512 Note: There is a limitation when you apply ADAM-4000 as remote I/O. The maximum of any mixed ADAM-4000 module is 32 nodes.
Page 142 Step 3. Database Development This is the last step to link ADAM-5511 and HMI software. Just fill the table to develop the database for ADAM-5511. HMI software will create a database table automatically. After completed the database development, it can be applied to...
Page 144 User-designed ADAM-5511 application programs make use of ADAM-5511 library functions. To make the most efficient use of ADAM-5511’s memory space, the ADAM-5511 function library has been separated into five smaller libraries. Therefore, a user can link only those libraries needed to run his application, and only those libraries will be included in the compiled executable.

Page 316 EIA RS-485 is the industry’s most widely used bidirectional, balanced transmission line standard. It is specifically developed for industrial multi-drop systems that should be able to transmit and receive data at high rates or over long distances. The specifications of the EIA RS-485 protocol are as follows: •...
Page 317 Multi-drop RS-485 implies that there are two main wires in a segment. The connected systems tap from these two lines with so called drop cables. Thus all connections are parallel and connecting or discon- necting of a node doesn’t affect the network as a whole. Since ADAM-5510/P31 systems use the RS-485 standard, they can connect and communicate with the host PC.
Page 318 In this scheme the repeaters are connected to drop-down cables from the main wires of the first segment. A tree structure is the result. This scheme is not recommended when using long lines since it will cause a serious amount of signal distortion due to signal reflections in several line-endings.
Page 319 This is a combination of daisychain and hierarchical structure.
Page 320 Each discontinuity in impedance causes reflections and distortion. When a impedance discontinuity occurs in the transmission line the immediate effect is signal reflection. This will lead to signal distortion. Specially at line ends this mismatch causes problems. To eliminate this discontinuity, terminate the line with a resistor.
Page 321 Because each input is biased to 2.4 V, the nominal common mode voltage of balanced RS-485 systems, the 18 kΩ on the input can be taken as being in series across the input of each individual receiver. If thirty of these receivers are put closely together at the end of the transmission line, they will tend to react as thirty 36kΩ...
Page 322 Thus as already stated above the line termination resistor R will normally equal the characteristic impedance Z The star connection causes a multitude of these discontinuities since there are several transmission lines and is therefore not recommend. Note: The recommend method wiring method, that causes a minimum amount of reflection, is daisy chaining where all receivers tapped from one transmission line needs only to be terminated twice.
Page 324 Unfortunately, it’s impossible to finish a system integration task at one time. We always meet some trouble in the field. A communication network or system isn’t stable, induced noise or equipment is damaged or there are storms. However, the most usual issue is just simply improper wiring, ie, grounding and shielding.
Page 325 As you know, the EARTH cannot be conductive. However, all build- ings lie on, or in, the EARTH. Steel, concrete and associated cables (such as lighting arresters) and power system were connected to EARTH. Think of them as resistors. All of those infinite parallel resistors make the EARTH as a single reference point.
Page 326 Single Phase, Three Line 110V 220V 110V Neutral is the physical cable from Generator. Ground is the local physical cable that connected to Ground Bar . Grounding is one of the most important issues for our system. Just like Frame Ground of the computer, this signal offers a reference point of the electronic circuit inside the computer.
Page 327 Have you ever tried to measure the voltage between a live circuit and a concrete floor? How about the voltage between neutral and a concrete floor? You will get nonsense values. ‘Hot’ and ‘Neutral’ are just relational signals: you will get 110VAC or 220VAC by measuring these signals.
Page 328 • Ground-pin is longer than others, for first contact to power system and noise bypass. • Neutral-pin is broader than Live-pin, for reducing contact imped- ance.
Page 329 • What’s the purpose of high voltage transmission? We have all seen high voltage transmission towers. The power plant raises the voltage while generating the power, then a local power station steps down the voltage. What is the purpose of high voltage transmission wires ? According to the energy formula, P = V * I, the current is reduced when the voltage is raised.

The above diagram shows you that a single point grounding system will be a more stable system. If you use thin cable for powering these devices, the end device will actually get lower power.
Page 333 • Single isolated cable The diagram shows the structure of an isolated cable. You see the isolated layer which is spiraled Aluminum foil to cover the wires. This spiraled structure makes a layer for shielding the cables from external noise.
Page 334 • Double isolated cable Figure 10 is an example of a double isolated cable. The first isolating layer of spiraled aluminum foil covers the conductors. The second isolation layer is several bare conductors that spiral and cross over the first shield layer. This spiraled structure makes an isolated layer for reducing external noise.

Power * Cascade those shields together by Soldering Supply Connect the shield to Frame-Ground of DC Power Supply. • Never stripping too much of the plastic cable cover. This is improper and can destroy the characteristics of the Shielded-Twisted-Pair cable.
Page 336 • The characteristic of the cable Don’t strip off too much insulation for soldering. This could change the effectiveness of the Shielded-Twisted-Pair cable and open a path to introduce unwanted noise.
Page 337 • Shield connection (1) If you break into a cable, you might get in a hurry to achieve your goal. As in all electronic circuits, a signal will use the path of least resis- tance. If we make a poor connection between these two cables we will make a poor path for the signal.
Page 338 • Shield connection (2) The previous diagram shows you that the fill soldering just makes an easier way for the signal.
Page 339 • Isolate noise sources in shielded enclosures. • Place sensitive equipment in shielded enclosure and away from computer equipment. • Use separate grounds between noise sources and signals. • Keep ground/signal leads as short as possible. • Use Twisted and Shielded signal leads. •...
