Supported Devices
The Modbus Monitor supports three classes of power
management devices: tightly integrated devices, generic
devices, and hybrid devices.
Tightly integrated devices are those device types which
are predefined in the Monitor. The Monitor has a copy of
these devices’ register maps in its memory, and knows
precisely where to find any data it needs from such a
device. The register maps of tightly integrated devices
may not be changed in any way. The display screens of
tightly integrated device types are also pre-defined and
may not be changed (see hybrid devices, below, for more
information on customizing displays).
Generic devices are user-defined. The Modbus Monitor
supports any power management device with register-
based Modbus RTU communications via RS-485. To set
up a generic device, the user must manually enter the
register map (or those parts of interest) into the Modbus
Monitor via the Monitor Configuration Tool (see
Chapter 7, Advanced Configuration). In contrast to the
tightly integrated devices, whose register maps have
already been programmed into the Monitor, the Monitor
knows nothing about a generic device until the user
enters this data. Event recording and special handling
registers are not supported for generic device types.
The third type of device supported by the Monitor is the
hybrid device. This device type is derived from a tightly
integrated device, but is not as loosely defined as a
generic device. A hybrid device type’s register map and
display screens are copied from the register map of a
tightly integrated device, but they may be modified like a
generic device. This allows some flexibility to be
supported by the Monitor without giving up the
convenience of pre-defined tightly integrated devices.
The display screens of tightly integrated devices may be
customized by creating a new hybrid device type based
on the tightly integrated device type in question, and
then modifying the display portion of the device type.
Chapter 7, Advanced Configuration, discusses the
creation and configuration of generic and hybrid device
types.
The Monitor supports up to 31 device types, including
the 21 tightly-integrated devices shown in Table 1. All
tightly integrated devices are fully supported by PMCS
6.0; a sub-set (devices indicated by an asterisk) is
supported by PMCS 5.1.
