Which modules can the PR 4511 be used with?

Omni Instruments Expert Response: The PR 4511 supports compatible PR 4000 and 9000 series devices and selected PR 3000 series modules. Compatible models include the PR 4114, 4116 and 4131. Available measurements, settings and diagnostics depend on the connected module.

Can the PR 4511 connect to a data logger?

Omni Instruments Expert Response: Yes, provided the logger supports RS485 Modbus RTU master operation. The logger must be configured to read the appropriate registers and data formats for the connected PR module.

Does the PR 4511 store historical measurements?

Omni Instruments Expert Response: Measurements can be read through the PR 4511 and recorded by an external logger or monitoring system. For an interface with built-in data logging and Bluetooth access, consider the PR 4512.

Can several PR 4511 interfaces share one network?

Omni Instruments Expert Response: Yes. Multiple interfaces can share an RS485 Modbus RTU network. Each requires a unique device address and compatible communication settings. Network wiring, loading and termination must follow the installation requirements.

What is the difference between the PR 8510 and PR 8511 cables?

Omni Instruments Expert Response: The PR 8510 provides daisy-chain connections for up to eight PR 4511 interfaces. The PR 8511 is a Y-splitter cable for connecting one interface into a daisy chain and continuing the wiring to other devices.

Is the RJ45 connector an Ethernet connection?

Omni Instruments Expert Response: No. It carries RS485 Modbus RTU communication. Connecting to a Modbus TCP Ethernet network requires a suitable protocol gateway.

Can settings still be changed from the front display?

Omni Instruments Expert Response: Yes. The PR 4511 retains local programming, process display and supported diagnostic functions alongside Modbus communication. Programming access can be password protected.

PR 4511 Programming display and Modbus RTU protocol interface for systems 4000 and 9000 devices. Each 4511 display can be used on several different units to allow for modification/transfer of operation parameters or on an individual unit as a fixed display for readout of process data and status, plus as an RS485 Modbus RTU connection to a local network. The 4511 display clicks onto the front of the device and an RJ45 connector on top of the unit allows for connection to a Modbus network.

Description

PR 4511 Modbus Communications Interface

The PR 4511 combines local programming and process display with an RS485 Modbus RTU interface. It allows a compatible PLC, SCADA system or other Modbus master to read process information and access device parameters. The isolated serial connection supports integration into a monitoring network while retaining front-panel configuration and diagnostics.

Application

The 4511 detachable display adds Modbus RTU RS485 serial communications to all current and future 4000/9000 series units
All individual unit operating parameters can easily and quickly be configured by using the Modbus communication or by using the front display menu
The 4511 display can be used to read the process signal, simulate the output signal, indicate sensor errors and internal device errors

Technical Characteristics

4511 has full 4501 functionality for programming and display
RS485 Modbus RTU protocol
Multi-drop half-duplex connection via shielded RJ45 connector on top of module
Modbus parameters such as address, baud rate, stop bit(s) and parity bits are configured from, and stored on, the 4511 interface
2.5kVAC galvanic isolation between serial wiring and 4000/9000 units
