Section 3 - Communication Enabler
• Programming display for system DRST devices
• Modbus RTU protocol interface over RS485
• Monitor process value from the built-in display
• High 2.5 kV isolation to host unit
• Shielded RJ45 Modbus connector on top
Section 4 - Applications
•The DRST-CM detachable display adds Modbus RTU RS-485 serial communications to all current and future
DRST units.
•The unit converts a wide array of sensors and analog device signals measured by the system DRST, 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 DRST 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 DRST-CM display can be used to read the process signal, simulate the output signal, indicate
sensor errors and internal module errors.
Section 5 - Technical Characteristics
•DRST-CM has full DRSL-DISPLAY 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 DRST units.
•Modbus parameters such as address, baud rate, stop bit(s), and parity bit are configured from the DRST-CM
display, which also stores parameters.
Section 6 - Mounting / Installation / Programming
•Mounting in Zone 2 / Div 2.
•The DRST-CM can be moved from one device to another. The individual system DRST unit configuration of the
first transmitter can be saved and downloaded to subsequent transmitters.
•Programmed parameters can be protected by a user-defined password.
•When mounted on devices that are installed upside down, a menu item allows the display on the DRST-CM to be
rotated 180o and the up/down buttons to switch function.

Modbus Basics

Section 10 - 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 DRST-CM.
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.

DRST-CM Supported Modbus Function Codes:
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.

are marked in bold)
Modbus RTU segment line termination:
A 120 Ohm resistor should be installed on both ends of a RS485 Modbus RTU segment loop to prevent
signal echoes from corrupting data on the line.

OMEGA ENGINEERING, INC. warrants this unit to be free of defects in materials and workmanship for a

Department will issue an Authorized Return (AR) number immediately upon phone or written request.
Upon examination by OMEGA, if the unit is found to be defective, it will be repaired or replaced at no
charge. OMEGA’s WARRANTY does not apply to defects resulting from any action of the purchaser,
including but not limited to mishandling, improper interfacing, operation outside of design limits,
improper repair, or unauthorized modification. This WARRANTY is VOID if the unit shows evidence of
