These must be observed accordingly. For the integration of shielded I/O cables in an equipotential bonding concept for the automation system, the following applies in principle: Shielded analog I/O cables may only be connected directly to functional earth ground potential at a single point. This results in the prevention of voltage equalization currents via the analog cable. Additional information is available on request. Other: In order to observe the tolerance of RTD inputs, make allowance for the effects of the connecting cable and connection method (2, 3, and 4-wire technology). The data contains the offset error, gain error, and linearity error. All percentage tolerance values refer to the relevant measuring range final value. Unless otherwise stated, nominal operation (nominal voltage US = UL = 24 V, preferred mounting position, default format "IB IL", default filter setting (4.5 ms), identical measuring range setting for channels, etc.) is used as the basis. For RTD inputs, the tolerances are specified in 4-wire connection method, the installation instructions should be implemented accordingly. Please also observe the values for temperature drift and the tolerances influenced by electromagnetic interference. The maximum tolerance values represent the worst-case measurement inaccuracy. They contain the theoretical maximum possible tolerances in the measuring ranges. Moreover, the theoretical maximum possible tolerances of the calibration and test equipment have been taken into consideration.

8 Connection Notes

9 Connection Examples

Figure 6 General connection example Always connect the analog sensors using shielded, twisted pair cables. Connect the shielding to the module using the shield connection clamp. The clamp connects the shield to FE on the module side. Avoid connection to FE from both sides. The module is supplied with a shield connector and a standard connector for each input channel. The shield connection can be used for the standard signal (current/voltage) as well as for the RTD signal. The module has an FE spring (metal clip) on the bottom of the electronics base. This spring establishes an electrical connection to the DIN rail. Use grounding terminals to connect the DIN rail to protective earth ground. The module is grounded when it is snapped onto the DIN rail. To ensure reliable functional earth grounding of the module even when the DIN rail is dirty or the metal clip is damaged, always ground the module via the FE terminal point (see Figure 6). 7280B005 AI AI AI AI AORTD RTD RTD RTD OUT2 U + -+-USUL + -INTERBUS IN OUT 12 3 4 56 7 89 1 0 11 12 Ideal current source Application: Passive 2-wire transmitter Variable resistor General actuator + - OUT2 The numbers above the module illustration indicate the connector slots.

15 Configuration

Module configuration is only required if the channels are not to be operated with the default values (see "Parameters for Configuration" on page 32). You can either configure the module via process data or via PCP and transmit analog values accordingly. If the module has been configured via PCP, subsequent configuration via process data is only possible if configuration via process data is permitted with the "Config Table" PCP object. To do this, in the "AO format, AI format, system bits" element set "Conf" bit = 1. As long as "Conf" = 0, the error bit is set in the status word when an attempt is made to configure via process data.

16 Configuration via Process Data

Five OUT process data words are available. The first output word represents the control word, the following words each refer to an analog channel. As confirmation for a control word action, the first input word contains a partial copy of the control word. For the device configuration, channel-specific parameter data is set in the relevant channel output words. Once configuration has been completed, and depending on the format set, the measured values in the corresponding input words are either transmitted to the controller board or to the computer.

16.2 Output Words OUT2 to OUT5 (Configuration)

Each channel can be configured independently of the other channels. The first channel is configured via the second output word, the second channel via the third output word, etc. If the format "IB IL" is set, the error code "measured value invalid" is output during configuration. If the configuration is invalid, a corresponding error message is output in the status word. The configuration is stored in a volatile memory. For command 40xxhex, specify the parameters for the appropriate channels 1 to 4 in OUT2 to OUT5. The parameter words are only evaluated by this command. Configuration words for analog inputs and outputs: – "Wire" indicates the number of wires for a resistance measurement. It is only relevant for the "Linear R ...", hex to Ehex). – "AO reset behavior" indicates the status of the analog outputs in the event of an INTERBUS reset and following power up. The failsafe value must be specified retentively via the Config Table PCP object. – "AO output range" indicates the range for the analog outputs. – "AI filter" indicates the time for the digital filter. – "AI measuring range" indicates the range for the analog inputs. An error message is generated during configuration due to the following reasons: – A reserved value was used. – Current or voltage is configured for "AI measuring range" AND 3 or 4-wire is configured for "Wire". – Configuration has already been carried out via PCP.

"PF" If bit 2 = 1, a peripheral fault is generated in the event of a sensor problem (overrange, underrange, open circuit). "AOV" If bit 1 = 1, the "Analog Out Values" object may be written. This specifies that analog values for AO1 and AO2 are specified via PCP and not via process data. "Conf" If bit 0 = 1, configuration via process data is permitted (command code 40xxhex). The format of the failsafe value must be the Inline format. If an invalid configuration is specified, a negative confirmation is generated with error message 08hex, 00hex or xx30hex. The low byte of the additional error code is 30hex (value is out of range), the high byte contains the number of the affected element. Example: Config Table is completely written with data (subindex 00) and the entry for channel 2 is invalid. In this case, the additional error code is equal to 0230hex.

20 Channel Conversion Times a nd Process Data Update Time

The process data update time is determined from the sum of the channel conversion times for all four channels. The analog outputs must be maintained within these times. The conversion time of a channel is determined from the channel parameterization and combines the filter time plus special additional times. Channel conversion time = (Filter time + Time for resistance measurement + Measuring time for 4-wire connection) x 3-wire factor Example: Channel 1: Measuring range 0 V to 10 V, filter time = 4.5 ms Channel 2: Measuring range 0 mA to 20 mA, filter time = 1.1 ms Channel 3: Measuring range Pt 100, filter time = 4.5 ms, 4-wire Channel 4: Measuring range Pt 1000, filter time = 4.5 ms, 2-wire with connector compensation * 4-wire measuring time also applies for 2-wire with connector compensation Analog Conversion Time According to the Example Above: Figure 18 Analog conversion time according to the example above Filter Time Time for Resistance Measurement 4-Wire Measuring Time 3-Wire Factor Filter 1: 4.5 ms Filter 2: 1.1 ms 0.2 ms for all resistance measurements 1 ms, if resistor is connected in 4-wire technology 2 ms, if resistor is connected in 3-wire technology; otherwise 1 ms Channel Configuration [hex] Filter Time Time for Resistance Measurement 4-Wire Measuring Time* 3-Wire Factor Channel Conversion Time 1 0000 4.5 ms 0 ms 0 ms 1 4.5 ms 2 0044 1.1 ms 0 ms 0 ms 1 1.1 ms 3 8009 4.5 ms 0.2 ms 1 ms 1 5.7 ms 4 800B 4.5 ms 0.2 ms 1 ms 1 5.7 ms Process data update time = total of all channel conversion times 17 ms 2 4 68 10 12 14 16 7285B0210 Channel 2 Channel 1 Channel 3 Channel 4 ...Channel 1 18 20

21 Behavior of the Analog Outputs in

the Event of INTERBUS Reset and Power Up Both analog outputs behave independently of each other.

22 Notes on Systematic and Random

Errors During Resistance and Temperature Measurement The extent of systematic and random errors (signal/noise ratio) is greatly influenced by the connection method and filter time selected. The lowest level of systematic and random deviations can be achieved by selecting 4-wire technology and a filter time of 4.5 ms.

22.1 Measures to Optimize Tolerances

– Set the filter time to 4.5 ms (default setting). – Reduce random errors through additional application filtering. – Minimize a large part of systematic errors through user-specific system calibration. – Short circuit unused RTD channels. – Increase the sensor grou nd (connect sensor ground, e.g., to a metal block). Attention: Connect only one end of the shielding. – For 2-wire connection, use the version with connector compensation. Event AO Reset Behavior Response INTERBUS reset Hold Analog value is held Reset If AO output range 4 mA to 20 mA is configured, 4 mA is output, otherwise 0 mA or 0 V is output Failsafe The failsafe value for the corresponding channel that is specified in the "Config Table" object is output Power up Hold Output of 0 V Reset 0 V or 0 mA Failsafe 0 V or 0 mA

22.2 Connection Method

The contact resistance of the connections and the cable resistances have virtually no effect due to the 4-wire connection technology. Figure 19 RTD 4-wire connection

22.3 RTD 3-Wire Connection

With 3-wire technology, the effect of the cable resistance on the measured result in the terminal is minimized by multiple measuring of the temperature-related voltage and corresponding calculations. With this connection method, one cable can be eliminated. Figure 20 RTD 3-wire connection RTD 2-Wire Connection With Connector Compensation 2-wire technology is a more cost-effective connection method. The long U+ and U- cables to the sensor are no longer needed here. They are jumpered directly at the connector. The temperature-related voltage is not directly measured at the sensor and therefore not falsified by the two cable resistances RL. This connection method is ideal for sensors with high R0 (e.g., Pt 1000, Ni 1000). With 2-wire connection with connector compensation, minimized tolerances can be achieved through: – Parameterization of t he terminal on a 4-wire connection – Direct jumpering of the U+ and U- connections at the live measuring cables A larger conductor cross section and sensors with higher R0 further improve the tolerances of these connection versions.

22.4 Systematic Errors Duri ng Temperature Measurement With 2-Wire Technology

With 2-wire connection method, the cable resistances are in series for the sensor resistance and result in systematic measuring errors. This is described in greater detail below. Figure 22 Systematic temperature measuring error ΔT depending on the cable length l Curves depending on the cable cross section A (Measuring error valid for: copper cable χ = 57 m/Ωmm TA = 25°C and Pt 100 sensor) Figure 23 Systematic temperature measuring error ΔT depending on the cable cross section A (Measuring error valid for: copper cable χ = 57 m/Ωmm2, TA = 25°C, l = 5 m, and Pt 100 sensor) Figure 24 Systematic tem perature measuring error ΔT depending on the cable temperature TA (Measuring error valid for: copper cable χ =5 7m /Ωmm2, l = 5 m, A = 0.25 mm2, and Pt 100 sensor) All diagrams show that the increase in cable resistance causes the measuring error. A considerable improvement is made through the use of Pt 1000 sensors. Due to the 10-fold higher temperature coefficient α (α = 0.385 Ω/K for Pt 100 to α=3 . 8 5Ω/K for Pt 1000) the effect of the cable resistance on the measurement is decreased by factor 10. All errors in the diagrams above would be reduced by factor 10. Figure 22 clearly shows the effect of the cable length on the cable resistance and therefore on the measuring error. The solution is to use the shortest possible sensor cables. Figure 23 shows the effect of the cable cross section on the cable resistance. Cables with a cross section of less than 0.5 mm2 cause errors to increase exponentially. Figure 24 shows the effect of the ambient temperature on the cable resistance. This parameter does not play a great role and can hardly be influenced but it is mentioned here for the sake of completeness.
