Modbus basics
Modbus is a “master-slave” system..., where the “master” communicates with one or multiple “slaves”.
The master typically is a PLC (Programmable Logic Controller), DCS (Distributed Control System), HMI (Human Machine
Interface), RTU (Remote Terminal Unit) or PC.
The three most common Modbus versions used are: MODBUS ASCII, MODBUS RTU and MODBUS/TCP.
In Modbus RTU, data is coded in binary, and requires only one communication byte per data byte. This is ideal for use over
multi-drop RS485 networks, at speeds up to 115,200 bps.
The most common speeds are 9,600 bps and 19,200 bps.
Modbus RTU is the most widely used industrial protocol and is supported by the 4511.
Modbus RTU:
To communicate with a slave device, the master sends a message containing:
Device Address - Function Code - Data - Error Check
The Device Address is a number from 0 to 247.
Messages sent to address 0 (broadcast messages) will be accepted by all slaves, but numbers 1-247 are addresses of specific
devices.
With the exception of broadcast messages, a slave device always responds to a Modbus message so the master knows the
message was received.
4511 Supported Modbus Function Codes:
Command Function code
Read Holding Registers* 03
Read Input Registers* 04
Write Single Register 06
Diagnostics 08
Write Multiple Registers 16
*Holding Registers and Input Registers contain identical data in PR 4511.
The Function Code defines the command that the slave device is to execute, such as read data, accept data, report status.
Some function codes have subfunction codes.
The Data defines addresses in the device’s memory map for read functions, contains data values to be written into the
device’s memory, or contains other information needed to carry out the function requested.
The Error Check is a 16-bit numeric value representing the Cyclic Redundancy Check (CRC).
Maximum number of registers which can be read or written at once:
For a read command, the limit is 8 registers at a baud rate up to 38,400 bps, 16 registers @ 57,800 bps and 32 registers @
115,200 bps.
For a write command, the limit is 123 registers at baud rates up to 115,200 bps.

Operating the function keys / display
In general
When using the PR 4511 for configuration of a PR 4000 or PR 9000 device, you will be guided through all parameters and can
choose the settings which fit the application. For each menu there is a scrolling help text which is automatically shown in line
3 on the display.
Configuration is carried out by use of the 3 function keys:
1will increase the numerical value or choose the next parameter
2will decrease the numerical value or choose the previous parameter
3will save the chosen value and proceed to the next menu
When configuration is completed, the display will return to the default state (monitor). Pressing and holding 3will return to
the previous menu or return to the default state without saving the changed values or parameters.
If no key is activated for 1 minute, the display will return to the default state without saving the changed values or
parameters.
For device-specific programming menus, please refer to the user manual for each device, e.g. PR 4116.

General installation instructions
Year of manufacture can be taken from the first two digits in the serial number.
For safe Ex installation the following must be observed: The device must be installed
by qualified personnel who are familiar with the national and international laws,
directives and standards that apply to this area.
To prevent ignition of the explosive atmospheres do not separate connectors when
energized and an explosive gas mixture is present.
To avoid the risk of explosion due to electrostatic charging of the enclosure, do not
handle the units unless the area is known to be safe, or appropriate safety measures
are taken to avoid electrostatic discharge.
Mounting of PR 4500 communications interface:
1. Insert the tabs of the PR 4500 into the slots at the top of the device.
2. Hinge the PR 4500 down until it snaps into place.
Demounting of the PR 4500 communication interfaces:
3. Push the release button on the bottom of the PR 4500 and hinge the PR 4500
out and up.
4. With the PR 4500 hinged up, remove from the slots at the top of the device.
