MODBUS COMMUNICATION ENABLER
4511
• Programming display for system 4000 and 9000 devices
• Modbus RTU protocol interface over RS-485
• Monitor process value from the built-in display
• High 2.5 kV isolation to host unit
• Shielded RJ45 Modbus connector on top
Applications:
• The 4511 detachable display adds Modbus RTU RS-485 serial communications
to all current and future 4000/9000 units.
• The unit converts a wide array of sensors and analog device signals measured
by the system 4000, like uni- and bipolar mA and voltage signals, potentiometer,
Lin. R, RTD and TC, to a Modbus communication line signal.
• When mounted on a system 9000 device any signal coming from or going to
I.S. classified area, like AI, AO, DI and DO signals, can be converted to a Modbus
network.
• All individual unit operating parameters can easily and quickly be configured by
using the Modbus communication or by using the front display menu.
• The easily readable 4511 display can be used to read the process signal,
simulate the output signal, indicate sensor errors and internal module errors.
Technical characteristics:
• 4511 has full 4501 functionality for unit programming, process signal monitoring
and diagnostics handling.
• Modbus RTU protocol is supported using a serial RS-485 communication wiring.
• Multidrop half-duplex connection via shielded RJ45 connector.
• High safe galvanic isolation of 2.5 kVAC between the serial wiring and the
connected system 4000/9000 units.
• Modbus parameters such as address, baud rate, stop bit(s), and parity bit are
configured from the 4511 display, which also stores parameters.
Mounting / installation / programming:
• Mounting in Zone 2 / Div 2.
• The 4511 can be moved from one device to another. The individual system
4000/9000 unit configuration of the first transmitter can be saved and
downloaded to subsequent transmitters.
• Programmed parameters can be protected by a user-defined password.
