accQcomm Interface Module Section 2 Installation and Operation 2.1 Programming 2.1.1 Configuration Software The accQcomm’s configuration software is a simple program for managing your site files. Install the program by inserting the CD-ROM in the appropriate drive on your PC. Run the application accQcomConfigSetupV1.00.exe. Connect your PC to the accQcomm’s serial configuration port on the front of the unit, or connect to the Ethernet port on the back, and open the accQcomm configuration software.
accQcomm Interface Module Section 2 Installation and Operation 2.2 Site Setup Begin creating a site file for the flow meter(s) connected to the accQcomm by clicking the Site tab (Figure 2-1) and enter the desired Site Name. Figure 2-1 Site tab 2.2.1 LCD Display 2-2 The accQcomm’s LCD can be configured to display several different types of information.
accQcomm Interface Module Section 2 Installation and Operation 2.2.2 Display Units In the Display Units box (Figure 2-2), click the pull-down menus to select the units of measure the accQcomm will use for displaying measured Flow, Velocity, Depth, Temperature, and Volume. Figure 2-2 Select units of measure 2.2.3 Totalizers Flow volume can be totalized separately for each connected instrument. Each totalizer will roll over when an ensemble is received, or when volumetric units of measure are changed.
accQcomm Interface Module Section 2 Installation and Operation Totalizer Mode There are three selectable totalizer modes: Net – Total flow includes both positive and negative (forward and reverse) flows. Positive – Total positive (forward) flow; negative (reverse) flow not included. Negative – Total negative (reverse) flow; positive (forward) flow not included. The selected totalizer mode applies to all connected instruments. When the mode is changed, all totalizers are reset to zero.
accQcomm Interface Module Section 2 Installation and Operation Instruments 2 and 3, when first made active, will have the default name of INACTIVE, which can be deleted and replaced with new names. Figure 2-4 Instrument settings and error counter 2.2.5 Error Handling and Timeouts A timeout (Figure 2-4) signifies that the accQcomm is not receiving readings in the proper format from the configured instrument within the specified time period (default setting 90 seconds).
accQcomm Interface Module Section 2 Installation and Operation 2.3 Communication Click the Communication tab to select the appropriate communication settings for the PC connection and each flow meter. Figure 2-5 Communication tab Note Record your Port and Network settings for future use.
accQcomm Interface Module Section 2 Installation and Operation Flow Control can be used when the accQcomm is communicating through a modem, to regulate data transmission so that when the buffer is full, data flow will halt until enough data has been read to continue transmitting. To activate this function, check the box next to Flow Control. 2.3.2 Network Settings In the Address box, enter the IP address you will use to access your flow data via the Internet, as well as the Subnet mask.
accQcomm Interface Module Section 2 Installation and Operation 2.4 Alarms The accQcomm has eight programmable relays for triggering alarms based on one or two user-defined conditions (i.e., flow rate, level, velocity, etc.). To program alarms, click the Alarms tab. Define the conditions by using the pull-down menus to select the instrument (flow meter), parameter (level, flow, etc.), comparator (>, <, ==, >=,<=), and value (Figure 2-7).
accQcomm Interface Module Section 2 Installation and Operation When you highlight the desired alarm number in the Current Alarms window and click Set Alarm Condition, the alarm appears beside its number. To remove an alarm condition, highlight the alarm and click Clear Selected. Note For the accQmin flow meter, the accQcomm displays and transmits secondary level data at 10X the actual value when using Standard Data format. This should be considered when setting up alarm conditions and analog outputs.
accQcomm Interface Module Section 2 Installation and Operation Alternate MODBUS Port Although ordinarily only MODBUS or Analog output (see next section) can be selected as the Output Type (refer to Figure 2-8 on the following page), an alternate MODBUS port can be used at the same time as Analog Output. To activate and configure this port while the Output Type is set for Analog, check the box next to “Use alternate MODBUS port.” Note that enabling this alternate port will disable instrument #2.
accQcomm Interface Module Section 2 Installation and Operation Ranges are user-defined using the 4mA and 20mA boxes. Parameter values will be displayed using the units entered in the Display Units box on the Site tab (see Section 2.2.2). Only the analog outputs installed at the factory will be operational when shipped. If additional outputs are required, call Teledyne Isco.
accQcomm Interface Module Section 2 Installation and Operation Note For the accQmin flow meter, the accQcomm displays and transmits secondary level data at 10X the actual value when using Standard Data format. This should be considered when setting up alarm conditions and analog outputs. This will not occur with an accQmin using Reduced Data format. Testing Analog Outputs To verify that the analog outputs are functioning properly. 1. Attach the leads of a current meter to the output circuit to be tested.
accQcomm Interface Module Section 2 Installation and Operation 2.6 Smoothing The smoothing function stabilizes data outputs by disregarding brief spikes in the condition being monitored. The Smoothing tab allows you to control several aspects of your data output, including the degree of smoothing, the smoothing cutoff point, minimum smoothed flow value, and smoothing on output display. Figure 2-11 Smoothing tab 2.6.
accQcomm Interface Module Section 2 Installation and Operation When selecting the TCF, keep in mind that the system’s response to any change within the specified range (see sections 2.6.2 and 2.6.3) is affected by smoothing. The data output becomes more uniform with smaller TCF settings, but this also lengthens the system’s response time to changes in conditions. If you have questions regarding the smoothing function and selection of the Time Constant Factor, contact Teledyne Isco at (866) 298-6174. 2.6.
accQcomm Interface Module Section 2 Installation and Operation 2.7 Alarm and Output Parameters Table 2-2 contains the parameters shown in the pull-down menus for selecting alarm and output functions. Table 2-2 Alarm and Output Parameters Alarm 4-20 Output Flow rate calculated from cross-sectional velocities Q Manning Flow rate calculated with Manning formula, for flow depths that fall below the velocity profiling range Smoothed flow Flow data with smoothing applied.
accQcomm Interface Module Section 2 Installation and Operation 2.8 Viewing Data Via Ethernet To view your flow data via LAN or Internet connection, or in TELNET using terminal emulation software such as HyperTerminal, the flow system must be connected online through the accQcomm’s Ethernet port. Open your browser and go to the URL shown in the Address box on the Communication tab in the accQcomm configuration software.
