The ConsoliDator+ Multivariable Controller supports Modbus
RTU, Modbus ASCII, Enron Modbus, and Ethernet Modbus
TCP/IP. The Server mode is a standard ConsoliDator+ feature; it
responds to requests and accepts writes from a Modbus client.
The ConsoliDator+ is now available with Modbus Client,
Snooper, and Spoofer capabilities and has the ability to scan
and display up to 199 Modbus registers. This feature can be
“unlocked” on any ConsoliDator+ purchased after February 15,
2021 by purchasing the PDK9000-M1 Key for $500 and entering
the Key value into the ConsoliDator+.
MODBUS CLIENT, SNOOPER & SPOOFER ADD-ON FEATURES
Snooper Mode
The Snooper mode can listen and read the process variables
being transmitted on the RS-485 bus without causing any
disruptions to the network. The controller can read up to 199
Modbus values, as inputs from other Modbus devices being
polled by a Modbus Client. The inputs can be used as the
source for channels, math functions, alarms, relay control, etc.
Client Mode
The Client mode can request process variables from server
devices; the input variables can be scaled, combined with
other variables using math functions, and they can be written
to other server devices using the Modbus output functions. The
controller can request up to 199 Modbus values, as inputs from
other Modbus devices. The inputs can be used as the source for
channels, math functions, alarms, relay control, etc.
Spoofer Mode
The Spoofer mode is designed to replace existing Modbus
Servers without requiring changes to the Client conguration.
Each process value can be assigned a specic Device ID and
Register Number to mimic the original server conguration.

Relay Connections
Relay connections are made to three-terminal connectors
labeled individually. There are ve relays per card.
Switching Inductive Loads
The ConsoliDator+ has internal circuitry to protect the relays
from inductive loads, however, the use of suppressors
(snubbers) is strongly recommended when switching
inductive loads to prevent disrupting the microprocessor’s
operation. The suppressors also prolong the life of the
relay contacts. Suppression can be obtained with resistor-
capacitor (RC) networks assembled by the user or purchased
as complete assemblies. Refer to the following circuits for RC
network assembly and installation.

as large as the load current.
RC Networks Available from Precision Digital
RC networks are available from Precision Digital and should
be applied to each relay contact switching an inductive load.
Part number: PDX6901.
Serial Communication Connections
The RS-485 port for serial communication (using Modbus
protocol) has three terminals labeled D+, D-, and G. It is
strongly recommended to use three-wire shielded cable
and to always connect the ground terminal to the other
equipment’s ground to avoid di󰀨erential voltage between
the systems. Distances up to 4000 feet can be reached with
RS-485. Up to 32 Modbus devices may be connected to a
single RS-485 bus.

Ethernet Option
The Ethernet port is available on the RJ45 connector. This
allows the ConsoliDator+ to connect to a local area network.
The Ethernet port option is congured using the System menu.
See the PD9000 ConsoliDator+ manual for ethernet port setup
details.
External Keypad Connections
Normally open pushbuttons may be wired to the digital inputs
connector for use when the front panel of the controller is not
accessible. The external keys may be assigned to replicate
the Menu and F1-F4 function keys.
