Product Manual Excerpt

IC693ALG442 Analog Combination I/O Module Analog Current/Voltage Combination Module 4 Input/2 Output Channels - IC693ALG442 The Analog Current/Voltage Combination Input/Output module provides up to 4 differential input current or voltage channels and 2 single-ended output channels with either current loop outputs or voltage outputs. Each channel can be individually configured for the current or voltage range, as applicable, required for your application. All module configuration is done through software, except for a jumper required for selecting the current input mode. All ranges can be configured using either the Logicmaster 90-30/20/Micro programming software configurator function or the Series 90-30 Hand-Held Programmer. Note that in this module s description, the module will be simply referred to as the Analog Combo Module. Each analog input is capable of providing five input ranges (two voltage and three current), which are: 0 to +10 volts (unipolar) - default range for both input and output channels. 10 to +10 volts (bipolar) 0 to 20 mA 4 to 20 mA 4 to 20 mA Enhanced The default input range is voltage mode 0 to +10 volts (unipolar) with user data scaled so that 0V corresponds to a count of 0 and 10V corresponds to a count of 32767. Each analog output is capable of providing four output ranges (two voltage and two current): 0 to +10 volts (unipolar) - default range for both input and output channels. 10 to +10 volts (bipolar) 0 to 20 milliamps 4 to 20 milliamps Each output channel is capable of converting 15 to 16 bits (depending on the range selected) of binary (digital) data to an analog output for use as required by your application. User data in 12 12-2 Series 90 30 PLC I/O Module Specifications July 2000 GFK 0898F the%AI and %AQ registers is in a 16-bit 2 s complement format. In current modes, an open-wire fault is reported to the CPU for each channel. The module can go to a known last state when system power is interrupted. As long as user power is applied to the module, each output will maintain its last value, or reset to the low end of the scale (range), as determined by how you have configured the module. Each output channel can be configured to operate in ramp mode using ladder logic. In ramp mode, changes in %AQ data cause the corresponding output channel to ramp to the new %AQ value. The ramp output consists of steps taken each millisecond until the final value is reached. High and low alarm limits can be set for all input channels and an open-wire fault (current output modes) is reported to the CPU for each output channel. All six analog channels may be updated on every scan, depending on the scan time. Table 12-1.

The other ranges are selected by changing the configuration parameters using the Logicmaster 90-30/20/Micro configurator software or the Hand-Held Programmer. In the 0 to 20 mA range user data is scaled so that 0 mA corresponds to a count of 0 and 20 mA corresponds to a count of 32000. Full 12-bit resolution is available over the 0 to 20 mA range. A 4 to 20 mA Enhanced range can also be selected. When this range is selected, 0 mA corresponds to a count of 8000, 4 mA corresponds to a count of 0 (zero) and 20 mA corresponds to a count of +32000. The Enhanced range uses the same hardware as the 0 to 20 mA range but automatically provides 4 to 20 mA range scaling with the exception that negative digital values are provided to the user for input current levels between 4 mA and 0 mA. This gives you the capability of selecting a low alarm limit that detects when the input current falls from 4 mA to 0 mA, which provides for open-wire fault detection in 4 to 20 mA applications. High and Low alarm limits are available on all ranges. Ranges can be configured on a per channel basis. User data in the %AI registers is in 16-bit 2 s complement format (0 to 20 mA range only). Resolution of the converted signal is 12 bits binary (1 part in 4096) on the 0 to 20 mA range. The placement of the 12 bits from the A/D converter in the %AI data word is shown below.

The relationship between the current input and the data from the A/D converter is show below. 4 A/D BITS (decimal) CURRENT (mA) a44647 0 20 0 4000 4 to 20mA RANGE Figure 12-1. A/D Bits vs. Current Input If the current source is reversed into the input, or is less than the low end of the current range, then the module will output a data word corresponding to the low end of the current range (0000H in %AI). If an input that is out of range is entered (that is, it is greater than 20 mA), the A/D converter will output up to full scale (corresponding to 7FFFH in %AI). Voltage Operation In the 0 to +10 V default range, user data is scaled so that 0 volts corresponds to a count of 0 and +10 volts corresponds to a count of 32000. The 10 to +10 volt range is selected by changing the A/D (decimal) CURRENT (mA) a44654 0 20 0 4000 0 to 20 mA RANGE 12 IC693ALG442 Analog Combination I/O Module GFK 0898F Chapter12 IC693ALG442 Analog Combination I/O Module 12-5 configuration parameters using the Logicmaster 90-30/20/Micro configurator software or the Hand-Held Programmer. In the 10 to +10 volt range user data is scaled so that 10 volts corresponds to a count of 32000 and +10 volts corresponds to a count of +32000. Full 12-bit resolution is available over either range. Since converters used in the analog input channels are 12-bit converters, not all of the 16 bits in the data tables contain data required for the conversion. A version of the 12 bits is placed within the 16-bit data word corresponding to the analog point (in the %AI table). The Series 90-30 PLC system handles the integration differently for the various analog modules. The CPU does not manipulate the data from the input channels before placing it within the word in the %AI data table. The bits in the %AI data table which were not used in the conversion by the input channel are forced to 0 (zero) by the analog input channel. Placement of the 12 data bits from the A/D converter for an analog current input data word for the 16-Channel Analog Voltage Input module in unipolar range is shown below. X D11 D10 D9 D8 D7 D6 D5 D4 D3 D2 D1 D0 X X X MSB LSB X=not converted bits Analog values are scaled over the range of the converter. Factory calibration adjusts the analog value per bit (resolution) to a multiple of full scale (that is, 2.5 mV/bit for unipolar; 5 mV/bit for bipolar). This calibration leaves a normal 12-bit converter with 4000 counts (normally 212 = 4096 counts). The data is then scaled with the 4000 counts over the analog range. For example, the data to the A/D converter for the Analog Voltage Input is scaled as shown below. A/D BITS (decimal) VOLTAGE; 0 to 10V RANGE a45717 0 10 0 4000 Figure 12-2.

In the 0 to 20 mA range, user data is scaled so that 0 mA corresponds to a count of 0 and 20 mA corresponds to 32000. Note that in the 0 to 20 mA mode, you can enter a value up to 32767 which provides a maximum output of approximately 20.5 mA. Scaling of the current output for both the 4 to 20 mA range and the 0 to 20 mA range is shown below. In current mode the module also provides an open loop fault detect which is reported to the PLC in the %I table. 4 %AQ (decimal) CURRENT (mA) a44683 0 20 0 32000 4 to 20 mA Range %AQ (decimal) CURRENT (mA) a44684 0 20 0 32000 0 to 20 mA Range Figure 12-3. Scaling for Current Output Voltage Operation For Voltage Operation in the default unipolar mode (0 to +10 volts), user data is scaled so that 0 volts corresponds to a count of 0 and +10 volts corresponds to a count of 32000. In this mode, you can enter up to 32767 for an overrange of approximately 10.24 volts output. In the 10 to +10 volt range user data is scaled so that 10 volts corresponds to a count of 32000 and +10 volts corresponds to a count of +32000. In this range, you can enter 32768 to +32767 for an overrange of approximately 10.24 volts to +10.24 volts. Scaling of the voltage output for both the 0 to +10 volt range and the 10 to +10 volt range is as shown below. %AQ (decimal) VOLTAGE (V) 0 a44658 10 10 32000 32000 0 Bipolar Mode %AQ (decimal) VOLTAGE (V) a45718 0 10 32000 Unipolar Mode 0 Figure 12-4.

For detailed information on the CPU interface to analog modules, refer to the Hardware Description of Analog Module section at the beginning of this chapter. Status Reporting The Analog Combo module module provides status information to the PLC. This status information is updated once each PLC sweep and consists of the following items: health of the module (all ranges) overload or open wire detect (current output mode only) alarm low and high status (input channels) status of the user-supplied power to the module (all ranges) Power Requirements and LEDs This module requires a maximum of 95 mA from the 5V bus on the PLC backplane for the logic side. The module s analog power must be supplied by a single, user supplied+24 VDC power source. This includes current loop output power and voltage output load power. This user supply requires a maximum current of 129 mA. There are two green LED indicators on the module which provide module and user supply status. The top LED, OK, provides module status information, and the bottom LED, USOK, indicates whether the user supply is present and is above a minimum designated level. Note that both LEDs are powered from the +5V backplane power bus. The LEDs have six possible status combinations, which are described below. LED Status Indications for IC693MDL442 Combination LED Status Description 1 OK USOK ON ON Module OK and configured User power is present 2 OK USOK FLASH OFF Module OK but not configured No user power 3 OK USOK FLASH ON Module OK but not configured User power is present 4 OK USOK ON OFF Module OK and configured No user power 5 OK USOK OFF OFF Module is defective or no +5V backplane power present User power may or may not be present 6 OK USOK OFF ON Module not OK User power is present Location in System The Analog Combo module is compatible with all Series 90 30 CPU models and may be installed in any I/O slot of any Series 90 30 baseplate. 12 12-8 Series 90 30 PLC I/O Module Specifications July 2000 GFK 0898F References Used and Maximum Modules per System Considerations The number of IC693ALG442 Analog Combo modules that can be installed in a system depends on the amount of %AQ, %AI, and %I references available. Each module uses 2 %AQ references and 4 %AI references (depending on status configuration) and 8, 16 or 24 %I references (depending on alarm status configuration). The number of these references is dependent on the type of CPU in your system. Please refer the the Maximum Number of Analog Modules per System table in Chapter 8 to determine how many Analog Combo modules can be installed for the various CPU models.
