Page 89: Data Logging
Fig 4-7 Basic settings 4.5 Data Logging meter provides data logging that records the data at a set Acuvim IIR/IIE/IIW interval.This meter has 8 MegaBytes of memory which gives it extensive data- logging capabilities. It has a real-time clock that allows logs to be time-stamped when log events are created.
Page 90 1. Data log settings meter has three sets of historical data logs. Each log can be Acuvim IIR/IIE/IIW independently programmed with individual settings, meaning that each can be used to monitor different parameters. You can program up to 117 parameters per log.
Page 91 Having three sets of historical logs provides you with the option of programming each log with unique parameters. For example, you can program Historical Log 1 to record measured values parameters (for example, Frequency, Voltage, Current), Log 2 to record energy values parameters, and Log 3 to record power quality parameters.
Page 92 • DI Counter (the DI numbers of the IO modules) • AO/AI Raw Value (the AO output register values and the AI sample register values) • AO/AI Value(the AO output values and the AI sample values) The following procedures show how to select and store parameters in historical log 1.

Page 240 6.1 Modbus Protocol Introduction Modbus RTU protocol is used for communication in Acuvim II series meters. Data format and error check methods are defined in Modbus protocol. The half duplex query and respond mode is adopted in Modbus protocol. There is only one master device in the communication network.
Page 241 addresses are in the range of 0~247 decimal. A master addresses a slave by placing the slave address in the address field of the message. When the slave sends its response, it places its own address in this address field of the response to let the master know which slave is responding.
Page 242 in the data field, and the data to be written into the registers. If no error occurs, the data field of a response from a slave to a master contains the data requested. If an error occurs, the field contains an exception code that the master application can use to determine the next action to be taken.
Page 243 bytes of the message have been applied,the final contents of the register, which should exchange the high-byte and the low-byte, is the CRC value. When the CRC is appended to the message, the low-order byte is appended first, followed by the high-order byte. 6.2 Communication Format Explanation of frame Table 6-3 Explanation of frame...

Page 284 parameters occupy two registers, to supplement this, the programmable settings for the historical logs contain a list of descriptors. Each descriptor lists the number of Modbus registers for the specified parameter. By combining these two lists, the historical log record can be interpreted. For example: Registers 4002H and 4003H are programmed to be recorded by the historical log.
Page 285 Registers: The number of registers to log in the record range from {0-117}. The size of the record in memory is [12 + (Registers x 2)]. Sectors: The number of memory sectors allocated to this log. Each sector is 64kb in size. 100 sectors are available for allocation among the three historical logs.
Page 286 Registers: 1177H– 11B1H Size: 1 byte per item, 117 bytes (59 registers) While the register list describes what to log, the Item descriptor list describes how to interpret that information. Each descriptor describes how many Modbus addresses are used to describe a parameter. Either 1 or 2 addresses will be used for each parameter.

Page 288 Log Retrieval Block The log retrieval block consists of 2 parts: the header and the window. The header is used to verify the data shown within the requested log window. The window is a sliding block of data that can be used to access any record in the specified log.
Page 289 Status: The status of the current window. Since the time to prepare a window may exceed an acceptable Modbus delay (1 second), this acts as a ready status flag to notify when the window is ready for retrieval. When this value indicates that the window is not ready, the data in the window should be ignored.
