IQ 250/260 Meter 4 Chapter 4: Electrical Installation Electrical Installation Considerations When Installing Meters Installation of the IQ 250/260 Meter must be performed only by qualified personnel who follow standard safety precautions during all procedures. Those personnel should have appropriate training and experience with high voltage devices. Appropriate safety gloves, safety glasses and protective clothing is recommended.
Chapter 4: Electrical Installation IQ 250/260 Meter CT Leads Terminated to Meter The IQ 250/260 is designed to have Current Inputs wired in one of three ways. Diagram 4.1 shows the most typical connection where CT Leads are terminated to the meter at the Current Gills. This connection uses Nickel-Plated Brass Studs (Current Gills) with screws at each end. This connection allows the CT wires to be terminated using either an “O” or a “U” lug. Tighten the screws with a #2 Phillips screwdriver.
Chapter 4: Electrical Installation IQ 250/260 Meter CT Leads Pass Through (No Meter Termination) The second method allows the CT wires to pass through the CT Inputs without terminating at the meter. In this case, remove the Current Gills and place the CT wire directly through the CT opening. The opening will accomodate up to 0.177” / 4.5mm maximum diameter CT wire. CT Wire passing through meter Current Gills removed Figure 4.2: Pass-Through Wire Electrical Connection www.eaton.

Hex Representation The representation shown in the table below is used by developers of Modbus drivers and libraries, SEL 2020/2030 programmers and Firmware Developers. The IQ 250/260 meter’s Modbus map also uses this representation.
Appendix B: Modbus Mapping for IQ 250/260 IQ 250/260 Meter Retrieving Logs Using the IQ 250/260 Meter with Option L’s Modbus Map This section describes the log interface system of the IQ 250/260 meters with the logging option from a programming point of view. It is intended for Programmers implementing independent drivers for Log Retrieval from the meter.
Appendix B: IQ 250/260 Modbus Map IQ 250/260 Meter Block Definitions This section describes the Modbus Registers involved in retrieving and interpreting an IQ 250/260 meter’s log. Other sections refer to certain ‘values’ contained in this section. See the corresponding value in this section for details. NOTES: Register is the Modbus Register Address in 0-based Hexadecimal notation. To convert it to 1based decimal notation, convert from hex16 to decimal10 and add 1. For example: 0x03E7 = 1000.

This is most commonly used in conjunction with the Digital I/O Option Cards. 0 NOTE: The interval between records will not be even (fixed), and thus should not be used with programs that expect a fixed interval. ii.

Unused Disabled: used as end list marker. 7-14 15 Size: The size in bytes of the item described. This number is used to determine the pairing of descriptors with register items.
Appendix B: Modbus Mapping for IQ 250/260 IQ 250/260 Meter NOTE: The first record in every log before it has rolled over is a “dummy” record, filled with all 0xFF’s. When the log is filled and rolls over, this record is overwritten. Record Size: The number of bytes in this record, including the timestamp. The data type is an unsigned integer in the range of 14 – 242. Log Availability: A flag indicating if the log is available for retrieval, or if it is in use by another port.
IQ 250/260 Meter Appendix B: IQ 250/260 Modbus Map To get the current Com Port, see the NOTE on querying the port, on the previous page. i. The Log Retrieval Header is used to program the log to be retrieved, the record(s) of that log to be accessed, and other settings concerning the log retrieval.
Appendix B: Modbus Mapping for IQ 250/260 IQ 250/260 Meter For example, with a record size of 30, the RecPerWindow = ((123 x 2) \ 30) = 8.2 ~= 8 Number of Repeats: Specifies the number of repeats to use for the Modbus Function Code 0x23 (35) (See next page for more information on this Function Code). Since the meter must pre-build the response to each log window request, this value must be set once, and each request must use the same repeat count.
IQ 250/260 Meter Appendix B: IQ 250/260 Modbus Map Log Retrieval Log Retrieval is accomplished in 3 basic steps: 1. 2. 3. Engage the log. Retrieve each of the records. Disengage the log. Auto-Increment In the traditional Modbus retrieval system, you write the index of the block of data to retrieve, then read that data from a buffer (window). To improve the speed of retrieval, the index can be automatically incremented each time the buffer is read.
Appendix B: Modbus Mapping for IQ 250/260 IQ 250/260 Meter Log Retrieval Procedure The following procedure documents how to retrieve a single log from the oldest record to the newest record, using the “normal” record type (see Scope). All logs are retrieved using the same method. See following section for a Log Retrieval example. NOTES: This example uses auto-increment. In this example, Function Code 0x23 is not used You will find referenced topics in the Block Definitions section.

The record index of the retrieved window is the index of the first record in the window. This value will increase by Records Per Window each time the window is read, so it should be 0, N, N x 2, N x 3 . . . for each window retrieved.

Since the window is 246 bytes, and the record is 18 bytes, 246\18 = 13.66, which means that 13 records evenly fit into a single window. This is 234 bytes, which means later on, we only need to read 234 bytes (117 registers) of the window to retrieve the records. 1.
Appendix B: Modbus Mapping for IQ 250/260 IQ 250/260 Meter If a record has all 0xFF for data, the timestamp is valid, and the index is NOT 0, then the record is legitimate. When the “filler” record is logged, its timestamp may not be “on the interval.” The next record taken will be on the next “proper interval,” adjusted to the hour. For example, if the interval is 1 minute, the first “real” record will be taken on the next minute (no seconds).

IQ 250/260 Meter App. B: Modbus Map Data Formats ASCII ASCII characters packed 2 per register in high, low order and without any termination characters. SINT16 / UINT16 16-bit signed / unsigned integer. SINT32 / UINT32 32-bit signed / unsigned integer spanning 2 registers. The lower-addressed register is the high order half. FLOAT 32-bit IEEE floating point number spanning 2 registers. The lower-addressed register is the high order half (i.e., contains the exponent).
IQ 250/260 Meter App. B: Modbus Map 19 Depending on the meter model, there are 15, 29, or 45 flash sectors available in a common pool for distribution among the historical and waveform logs. The pool size, number of sectors for each log, and the number of registers per record together determine the maximum number of records a log can hold.
Appendix C: IQ 250/260 Meter Using DNP Mapping for IQ 250/260 App.C Using DNP Mapping for IQ 250/260 Overview This Appendix describes the functionality of the IQ 250/260 meter's version of the DNP protocol. A DNP programmer needs this information to retrieve data from the meter. The DNP version used by the IQ 250/260 is a reduced set of the Distributed Network Protocol Version 3.0 subset 2; it gives enough functionality to get critical measurements from the meter.
Appendix C: Using DNP Mapping for IQ 250/260 IQ 250/260 Meter Application Layer The IQ 250/260 meter’s DNP version supports the Read function, Write Function, the Direct Operate function and the Direct Operate Unconfirmed function. The Read function (code 01) provides a means for reading the critical measurement data from the IQ 250/260 meter. This function should be posted to read object 60 variation 1, which will read all the available Class 0 objects from the DNP register map.
