Modbus

From July 15th, 2019, Modbus TCP protocol will be added to all PRECISE-LOG series of data loggers. A Modbus master/client can read one or more Input Registers and Holding Registers available in a PRECISE-LOG data logger through Modbus TCP communications.

The below specifications list all supported commands and available registers PL-TW data logger supports:

Input Registers:

An Input Register stores a 16-bit integer for a channel’s real-time reading. To read one or more 16-bit Input register data, use function code 4.

Register Description Type Range
0 CH0 Value Unsigned Integer 0 - 65535
1 CH1 Value Unsigned Integer 0 - 65535
2 CH2 Value Unsigned Integer 0 - 65535
3 CH3 Value Unsigned Integer 0 - 65535
4 CH4 Value Unsigned Integer 0 - 65535
5 CH5 Value Unsigned Integer 0 - 65535
6 CH6 Value Unsigned Integer 0 - 65535
7 CH7 Value Unsigned Integer 0 - 65535
8 CH8 Value Unsigned Integer 0 - 65535

Example:

To read CH2, CH3 and CH4's real-time values, a Modbus master device sends in the following command:

Data(HEX) Description Note
0001 Transaction identifier Fixed 2-byte value
0000 Protocol identifier Fixed 2-byte value
0006 Length(6 bytes are followed) 2-byte value

0003 The number of required registers (read 3 registers 0002 to 0004) 2-byte value

Holding Registers:

A Holding Register stores a 16-bit integer indicating a setting for the data logger. To read one or more 16-bit Holding Register data, use function code 3.

Note:

  1. Modbus feature was added to firmware version 2.05 or above.To upgrade a data logger's firmware please refer to this link: How can I upgrade logger firmware?
  2. The age of an Input Register data is based the data logger's sample interval.If the logger has stopped logging or the logger's sampling interval is slower than five seconds, a request of Input Register data will initiate the sampling process and the new data will be available upon the next request.
