1 General This document specifies a subset of the Modbus serial communications protocol used to transfer data between a master computer station and the PM174. The document provides the complete information necessary to develop third-party communications software capable of communication with the PM174.
Modbus protocol in the PM174. 2.1 Transmission Modes The PM174 can be set up to communicate on a serial Modbus network using either RTU, or ASCII serial transmission mode, and via the Internet using Modbus/TCP mode. Refer to the PM174 Installation and Operation Manual for information on selecting the transmission mode in your meter.
To map the PM174 register address to the range of the Modbus holding registers, add a value of 40001 to the PM174 register address. When a register address exceeds 9999, use a 6-digit addressing scheme by adding 400001 to the PM174 register address.
If the raw data reading is 250 then the current reading in engineering units will be as follows: Amps reading = 250 × (400.00 - 0)/(9999 - 0) + 0 = 10.00A 3. Power readings a) Assume device settings (direct wiring): Wiring 4LL3; PT = 1; CT primary current = 200A; Voltage scale = 828V.
2.7 User Assignable Registers The PM174 contains 120 user assignable registers in the address range of 0 to 119, any of which you can map to any register address accessible in the instrument. Registers that reside in different locations may be accessed by a single request by re-mapping them to adjacent addresses in the user assignable registers area.
The PM174 keeps a separate read pointer for each communication port so that access to the same file through a different port will not affect current active sessions for other ports.
Moreover, the PM174 takes all channel data for the currently accessed record to a separate buffer, so that even when the record is overwritten at the time of reading, you are still prevented from receiving partially updated data.
which sequence number is known, you can change the pointer position by issuing the Set- File-Position request with the desired sequence number. If you want to read a file from the beginning, send the Reset-File-Position request that moves the pointer to the oldest file record.
2. Write the Read-File request with the section number and channel ID as shown in the previous step. 3. Read the record data from the file response block. 4. Write an acknowledgment for the file. The file section pointer will be moved to the next record.

In case of triggering notifications with events generated by the PQ and Fault recorders, like the PQ EVENT or FAULT EVENT triggers, the recorded power quality or/and corresponding fault events are reported instead of setpoint-triggered notifications. Notification messages contain the fault event start and end time, a critical phase and the maximum fault magnitude on the reported phase.

NOTES: File sections for partitioned (multi-section) files, like Billing/TOU profile log files, can be requested either by a section number, or by a section channel ID. If a section number is set to 0xFFFF, the section channel ID will be used to identify the section. The section number will be returned in the response block. If a section number is written, then the corresponding channel ID will be returned in the file response block.

1) For bi-directional analog output (±1 mA), the zero scale setup corresponds to the center (0 mA) of the scale range, and the direction of the current matches the sign of the output parameter. Unsigned parameters are output within the current range 0 to +1 mA and can be scaled as in the case of single-ended analog output (0-1 mA).
