  1 GENERAL This document specifies a subset of the Modbus serial communications protocol used to transfer data between a master computer station and the PM130. The document provides the complete information necessary to develop a third-party communications software capable of communication with the Series PM130 Powermeters.

  06 and 16). In this case all instruments receive the message and take action on the request, but do not issue a response. In the PM130, the broadcast mode is supported only for register addresses 287-294 and 301-302 (reset energies and maximum demands), 3404-3415 (reset/clear registers), and 4352-4358 (real-time clock registers).

  Section 4.2.1). 4.3 User Assignable Registers The PM130 contains the 120 user assignable registers in the address range of 0 to 119 (see Table 4-1), any of which you can map to either 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 setpoint alarm register stores the status of the operated setpoints by setting the appropriate bits to 1. The alarm status bits can be reset all together by writing zero to the setpoint alarm register. It is possible to reset each alarm status bit separately by writing back the contents of the alarm register with a corresponding alarm bit set to 0.

• Page 29: Min/Max Log

  The Min/Max log registers are supported only for compatibility with other models of instruments. Because the Min/Max log is not time stamped in the PM130, reading these registers returns you only values of the Min/Max log parameters which you can read directly via extended data registers (see Table 5-15).

PM130 PLUS Quick Start Manual

This Quick Start Manual is a short guide on how to mount, connect, configure and operate the

PM130 PLUS. It is not intended to replace reading the full User Manual – and particularly the

safety precautions. The manual is available on the Product Documentation CD.

Mounting, electrical connection and settings of the PM130 shall be made in

accordance with all applicable laws and/or regulations and be performed by

authorized personnel only.

MOUNTING

Position the PM130 meter in 92×92mm square or 4″ round cutout (Figure 1). If two PM130 are

positioned side by side, keep at least 150mm (5.9″) between their centers to allow installation

of add-on modules (140mm/5.5″ if only small form modules will be used).

Attach the PM130 unit using washers and nuts. Make sure that the unit is securely attached

into the wall or cabinet fixture.
