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+.

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.

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.

Spoofer Mode

The Spoofer mode is designed to replace existing Modbus Servers without requiring changes to the Client configuration. Each process value can be assigned a specific Device ID and Register Number to mimic the original Client configurations.
