7 1.4.2 Optional Network Interface With Optional Isolated Digital Pulse Input (Di3) The D-100-P1 Display can be provided with an auxiliary input pulse for totalizing pulse outputs from external devices such as water or gas meters. Pulses are accumulated in an internal register, and the totalized value is available on the network. This register can be zeroed via the network. If the auxiliary pulse input option was ordered at the same time the display was ordered, it will arrive fully configured and ready to use. If it was ordered after the display was delivered and is being installed as a field upgrade, it may be necessary to configure the pulse input. The information is provided below and on the following pages: The input pulse must meet the following criteria: 1. Frequency input range, 50 Hz maximum millisecond minimum pulse duration Input Pulse Definition: In order to configure the communications card for an auxiliary input pulse, you must first determine which type of pulse your meter produces. The allowable types of input pulses are described on the following pages. Based on the type of pulse, set the selector switch (S1) on the communications circuit board (Fig. 1) to the correct setting.

15 SECTION 2.0: NETWORK IMPLEMENTATION STRATEGIES 2.1 IMPLEMENTATION STRATEGIES Monitoring Several D-100 parameters are available for monitoring purposes. These include Volume Rate (Point 4), Ai3 - Generic Analog Input 1 (Point 5), and Ai4 - Generic Analog Input 2 (Ppoint 6). These points can be unbundled for use in trending the performance of the hydronic system or used in various global control strategies. Totalization Three D-100-P1 Display parameters are available for accumulating totalized data. These are Mode 1 Volume Total (Points 11 & 12), Mode 2 Volume Total (Points 15 & 16) and (optional) auxiliary input (Points 17 & 18). Typically the Mode 1 and Mode 2 Volume Total points of the D-100-P1 Display are used to quantify the amount of water consumed in custody transfer applications. They may also be used to accumulate total consumption for use in ongoing plant or system efficiency measurements. D-100-P1 Display totalization registers are 7 digit registers. User defined units and multipliers are then applied to these values. This is required to allow for the accumulation of totals over a reasonable time period without exceeding the capacity of the reigster. P1 variables are limited in range to 32,767. In order to properly convey the D-100 information, each totalization register is represented by two separate type 3 LAI points. The first point represents digits from 0-9,999. The second point represents the digits from 10,000 to 9,999,999. The user-selected multiplier is applied to the units for the first word. For the second point, the multiplier is adjusted by a factor of 10,000, then applied to the units. Multipliers ONICON D-100 Volume Rate and Accumulation Points have multipliers. Multipliers are 1, 10, 100, 1,000, 10,000, 100,000 or 1,000,000. For points 11, 12, 15, 16, 17, and 18 the point descriptor will contain the multiplier. The 11 multipliers are as follows: Characters Multiplier 1 1 X 10 C 100 K 1,000 XK 10,000 CK 100,000 M 1,000,000 XM 10,000,000 CM 100,000,000 KM 1,000,000,000 XKM 10,000,000, Belcher Road South, Largo, FL USA Tel +1 (727) Fax +1 (727) sales@onicon.com D-100-P1 Flow Display Manual 10/ / Page 15

16 Example The D-100-P1 Display is running Application xxxx. The display shows the Volume Total as GAL x 100. The associated P1 variables would be as follows: Point CGAL Point MGAL To bring this value into the APOGEE Automation System, assign a Virtual Point for Volume Total: Volume Total = (Point 11 x 100) GAL+ (Point 12 x 1,000,000) GAL Volume Total = (2604 x 100) GAL+ (12 x 1,000,000) GAL Volume Total = GAL GAL Volume Total = GAL NOTE: Volume Total to equal ONICON display you must divide the number above by 100 to get GAL x / 100 = GAL x OTHER FUNCTIONALITY Each of the following functions of the D-100-P1 Display are also available and may be required, depending on the application. Mode Status Mode Status (Point 8) provides a separate indication of flow direction in bi-directional flow applications. For bi-directional flow applications, Mode 1 represents flow in the direction of the arrow on the flow meter enclosure. Resetting Totals Separate type 1 LDO points are provided to reset each totalizing register. These are Mode 1 Volume Total Reset (Point 22) Mode 2 volume Total Reset (Point 24, and Auxiliary Input Total Reset (Point 25).
