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.5.5.4 DC Latching OutputsPin DC Latching Outputs Modbus Register Description Wiring9 D1A507 Write a 1 to the output register to activate the DCLatching output from A to B.Write a 0 to the output register to deactivate the DCLatching output form B to A. DBDA 2-wireself-latchingsolenoid10 D1B11 D2A50812 D2BThe DXM Configuration Tool allows the user to adjust parameters that govern the operation of the DC latch outputs. Mostapplications will not require any changes for correct operation. DXM Configuration Tool parameters include:• Enable H-Bridge—Enable or disable the H-bridge output. Default Enabled.• Voltage—The voltage applied to the output when the output is activated. Default 13 V dc.• Cap Warmup Time—The amount of time given to charge the output capacitor. The more time given to charge theoutput capacitor the more energy will be available to turn on the output. Default 80 ms• Switch Time—The amount of time the output is turned on to be able to change the solenoid output. Default 40ms5.5.5 SDI-12 InterfaceThe SDI-12 interface on the DXM100-B2 Wireless Controllers can supportup to five devices with twelve 32-bit register values each. The DXM100-B2SDI-12 interface can be configured to increase the number of registers perdevice address for devices with large register sets. The factory defaultenables one SDI-12 device using device address 1 with up to nineregisters with a SDI-12 command of "M!".The DXM100-B2 controller is configured by writing non-volatile Modbusregisters with configuration parameters. Read or write the deviceconfiguration parameters using standard Modbus commands.powergroundserial D12GNDP12SDI-12deviceDXM100-B2ControllerBasic SDI-12 Interface ParametersUp to five devices/commands can be accessed using the SDI-12 interface. There are three parameters for each device/command: Enable, Device Address, Device Command. For more information, refer to the SDI-12 Technical Notes.Enable. Instructs the DXM Slave device to activate or deactivate the SDI-12 device. Write a 1 to enable, and write a 0 todisable. The factory default for device 1 is enabled; devices 2 through 5 are disabled.Device Address. Each SDI-12 device must have a unique device address. This parameter is the ASCII code for the deviceaddress. Valid device addresses are 0–9 and a–z that map to ASCII codes 48–57 and 97–122, respectively. The factorydefault addresses are:• SDI-12 Device 0 uses ASCII code 48• SDI-12 Device 1 uses ASCII code 49• SDI-12 Device 2 uses ASCII code 50• SDI-12 Device 3 uses ASCII code 51• SDI-12 Device 4 uses ASCII code 52DXM100-Sx Wireless Modbus Slave34 www.bannerengineering.com - Tel: +1.763.544.3164
