• 2952 Enable Default Communication Timeout. A “communication timeout" refers to the communication between anyModbus master host and the DXM baseboard. Set this register to 1 to enable the default condition when the hosthas not communicated with the DXM baseboard for the period of time defined by the Communication Default IOTimeout.• 2953 Communication Default I/O Timeout (100 ms/Count). This parameter defines the host timeout period in 100millisecond increments. If a host does not communicate within this timeout period, the device outputs are set to thedefault values.• 2954 Enable Default on Power Up. Setting this parameter to 1 sends the device outputs to their default conditionwhen the DXM baseboard is powered up. Set to 0 to disable this feature.Default Output State. The Default Output State parameter represents the default condition of the analog output. When anerror condition exists, the outputs are set to this 16-bit user-defined output state. To define the error conditions for deviceoutputs, refer to the MultiHop default output parameters 2950-2954.Enable Register Full Scale. Set to 1 to enable a linear range from 0 to 65535 for specified input range. For a 4 to 20 mAoutput, a value of 0 represents 4 mA and 65535 represents 20 mA. Set this parameter to 0 to store readings in unit-specificdata. For example, the register data representing a 15.53 mA reading is 15530. For units of current (0 to 20 mA outputs),values are stored as μA (micro Amps) and voltage values are stored as mV (millivolts).Hold Last State Enable. Set the Hold Last State to 1 to set the output to its last known value before the error occurred. Setthis parameter to 0 to disable the Hold Last State and use the Default Output State setting during an error condition.Maximum Analog Value. The Maximum Analog Value register stores the maximum allowed analog value. The specific unitsof measure apply to the register value. For example, the register may contain 20000, for 20 mA, or for a voltage output theregister may contain 8000, for 8 volts.Minimum Analog Value. The Minimum Analog Value register stores the minimum allowed analog value. The specific units ofmeasure apply to register value. For example, the register may contain 4000, for 4 mA, or for a voltage output the registermay contain 2000, for 2 volts.4.5.5 Universal InputsThe universal inputs can be programmed to accept different types of inputs: discrete NPN/PNP, 0 to 20 mA analog, 0 to 10V analog, 10k thermistor, potentiometer sense, bridge, and NPN raw fast. Use the DXM Configuration Tool tool to write tothe appropriate Modbus registers in the I/O board to configure the input type.The universal inputs are treated as analog inputs. When the universal inputs are defined as mA, V, or temperature, useModbus registers to configure the operational characteristics of the inputs. These parameters are temperature conversiontype, enable full scale, threshold and hysteresis. See the Modbus register section for the parameter definitions.When a universal input is configured as an NPN or PNP input type, it can be enabled to be a synchronous counter. Enablethe counter function by setting Modbus register 'Enable Rising' or 'Enable Falling' to 1. SeeModbus Registers for theuniversal input register definitions.Pin Univ. Input DescriptionPin 47 Universal Input 1 Program the universal inputs to accept input types NPN, PNP, 10k thermistor, 0 to 10 V, 0 to20 mA, or potentiometer. The default setting is 8: NPN raw fast. To set the input type, write thefollowing values to the Input Type Modbus registers.0 = NPN1 = PNP2 = 0 to 20 mA3 = 0 to 10 V dc4 = 10k Thermistor5 = Potentiometer Sense (DXM150 only)6 = Not used7 = Bridge8 = NPN Raw Fast (default)Pin 46 Universal Input 2Pin 43 Universal Input 3Pin 42 Universal Input 4Pin 40 Universal Input 5Pin 39 Universal Input 6Pin 38 Universal Input 7Pin 37 Universal Input 8Thermistor Input. A thermistor input must use a 10k thermistor between ground and the universal input. The thermistor mustbe a 10k NTC (Banner model number BWA-THERMISTOR-002) or equivalent. Select the temperature conversion of degreesC (default) or degrees F by writing to the Modbus registers defined inI/O Base Board.Potentiometer Sense (DXM150 only). A potentiometer input is created from two inputs: a voltage source (pin 45) thatsupplies a voltage to the potentiometer and an input sense (Potentiometer Sense) to read the resistance. FollowExample:Change Universal Input 8 to Read a Potentiometer Input on page 18 to configure the DXM150 Controller for apotentiometer input.Potentiometer Input (DXM100 only). A potentiometer input is created from three inputs: a voltage source (pin 30) thatsupplies 5 V to the potentiometer and two inputs set to voltage inputs to read the voltage across the potentiometer. See theDXM technical note for setting up a potentiometer.DXM150-Sx Wireless Modbus Slavewww.bannerengineering.com - Tel: +1.763.544.3164 17
