4.4 Logging
4.4.1 Max Demand Log
The PMC-509 provides an extensive list of Maximum Demand parameters with timestamp since the
last reset. Please refer to Section 3.5.1 for more details.
The Maximum Demand can be reset manually from the front panel or via communications. Please
refer to Section 3.5.3 for more details on how to reset the Maximum Demand from the Front Panel.
4.4.2 Data Recorder (DR) Log
The PMC-509 comes equipped with 8MB of memory and provides up to 8 Data Recorders (DR)
capable of recording 16 parameters each. The recorded data is stored in the device’s non-volatile
memory and will not suffer any loss in the event of a power failure.
The programming of the Data Recorder is only supported over communications. Each Data Recorder
provides the following setup parameters:
1) Triggered Mode: 0=Disabled / 1=Triggered by Timer / 2=Triggered by Setpoint
2) Recording Depth: 0 to 65535 (entry)
3) Recording Interval: 1 to 3456000 seconds
4) Recording Offset: 0 to 43200 seconds
5) Number of Parameters: 0 to 16
6) Parameter 1 to 16: 0 to 115 (Please see Appendix A DR Parameters)
The Data Recorder Log is only operational when the values of Triggered Mode, Recording Depth,
Recording Interval, and Number of Parameters are all non-zero.
The Recording Offset parameter can be used to delay the recording by a fixed time from the
Recording Interval. For example, if the Recording Interval parameter is set to 3600 (hourly) and the
Recording Offset parameter is set to 300 (5 minutes), the recording will take place at 5 minutes after
the hour every hour, i.e. 00:05, 01:05, 02:05, …etc. The programmed value of the Recording Offset
parameter should be less than that of the Recording Interval parameter.

Chapter 5 Modbus Register Map
This chapter provides a complete description of the Modbus register mapping (Protocol Version V1.0)
for the PMC-509 MDI (Maximum Demand Indicator) to facilitate the development of 3rd
party
communications driver for accessing information on the PMC-509. The PMC-509 supports the
following Modbus functions:
1) Read Holding Registers (Function Code 0x03) 2) Force Single Coil (Function Code 0x05) 3) Preset Multiple Registers (Function Code 0x10) 4) Read General Reference (Function Code 0x14)
The register addresses are listed as Offset addresses without the Modbus Address Prefix, 4 for

Table 5-10 DR Setup Parameters Data Structure
Notes: 1) The Data Recorder can be triggered by Setpoints (Triggered by Setpoint), or on a time basis
using the meter clock (Triggered by Timer). For Triggered by Setpoint, the Data Recorder starts recording when the setpoint becomes active and stops when the Setpoint becomes inactive.
2) If the “Recording Depth” is set to “0”, the Data Recorder will be disabled. 3) The Recording Offset parameter can be used to delay the recording by a fixed time from the
Recording Interval. For example, if the Recording Interval parameter is set to 3600 (hourly) and the Recording Offset parameter is set to 300 (5 minutes), the recording will take place at 5 minutes after the hour every hour, i.e. 00:05, 01:05, 02:05…etc. The programmed value of the Recording Offset parameter should be less than that of the Recording Interval parameter.
4) If the “Number of parameters” is set to “0”, the Data Recorder will be disabled. 5) The Data Recorder can record any one of the 116 parameters documented in Appendix A
Data Recorder Parameters.
28
Ceiec Electric Technology
6) Modifying “Recording Mode”, “Recording Depth”, “Recording Interval”, “Recording Offset”, “Number of Parameters” and “Parameters 1 to 16” will clear the DRx Log.
7) The number of Data Recorder is a dynamic variable, but the sum of all space can’t exceed 8M.
5.6 Time
There are two sets of Time registers supported by the PMC-509 -
Year/Month/Day/Hour/Minute/Second (Registers # 60000 to 60002 for 6-digit addressing and
Registers # 9000 to 9002 for 5-digit addressing) and UNIX Time (Registers # 60004 to 600005 for
6-digit addressing and Registers # 9004 to 9005 for 5-digit addressing). When sending time to the
PMC-509 over Modbus communications, care should be taken to only write one of the two Time
register sets. All registers within a Time register set must be written in a single transaction. If
registers 60000 to 60004 (9000 to 9004 for 5-digit addressing) are being written to at the same time,
both Time register sets will be updated to reflect the new time specified in the UNIX Time register set
60004 (9004) where the time specified in registers 60000 to 60003 (9000-9003 for 5-digit addressing)
will be ignored. Writing to the Millisecond register 60003 (9003 for 5-digit addressing) is optional
during a Time Set operation. When broadcasting time, the function code must be set to 0x10
(Pre-set Multiple Registers). Incorrect date or time values will be rejected by the meter.
