2. INTRODUCTION, MODBUS PROTOCOL
The Modbus Protocol is an industry-standard communications protocol that is selectable with all
our serial communications signal options: Ethernet, USB, RS485 and RS232. It is implemented by
the microcomputer on the main board and is compliant with Modbus RTU or ASCII transmission
modes (software selectable), as specified in Modbus over Serial Line Specification V1.0 (2002).
Digital panel meters, counters and timers require a plug-in option board for Modbus communications. This board can be any of the following:
• RS232 board
• RS485 board with dual RJ11 jacks.
• RS485 Modbus board with dual RJ45 jacks
• USB board
• USB-to-RS485 converter board
• Ethernet board
• Ethernet-to-RS485 converter board
Our RS485 and Modbus RS485 boards are both Modbus compliant, but the RS485 board uses
RJ11 jacks while the Modbus board uses RJ45 jacks as recommended in the Modbus Specification. With either board, the two jacks are wired in parallel to allow daisy chaining of meters with
no need for a hub.
Our USB-to-RS485 and Ethernet-to-RS485 converter boards allow the host meter to function as a
normal meter, be connected to a host computer or Ethernet local area network (LAN), and also act
as the device server for an RS485 network with up to 31 other meters equipped with an RS485
board. These meters can then be daisy-chained using readily available, straight-through 6-wire
data cables (not 4-wire telephone cables or crossover cables). Use repeaters to increase the
number of addressable meters.
Our DIN-rail transmitters come with a user-selectable Ethernet or RS232/RS485 I/O port in addition to a scalable 4-20 mA output, which is standard.
Our DIN-rail Ethernet-to-RS485 device server provides an RJ45 jack for connection to the
Ethernet, an RJ11 jack to support an RS485 network of meters, plus screw terminals to support
an RS485 network of DIN-rail transmitters via a set of 3 or 5 parallel wires (half- or full-duplex).
The Modbus TCP protocol is seamlessly converted by our Ethernet Nodes to Modbus RTU or
Modbus ASCII for communication with meters and transmitters on an RS485 bus. Please see our
Ethernet Manual for more information.
The Custom ASCII Protocol is a software-selectable alternative to the Modbus Protocol. It also
allows device addressing of up to 31 devices. It is less complex than the Modbus protocol, but is
limited to use with our devices. Please see our Custom ASCII Protocol Communications Manual.

4. JUMPER SETTINGS & FIELD WIRING
1. SAFETY WARNINGS
Digital panel meters, counters, timers and transmitters may be powered with AC (mains) from
85-264 Vac or 95-300 Vdc with standard high voltage power, or 12-34V ac or 10-48 Vdc with the
low voltage power supply option. To avoid the possibility of electrical shock or damaging short
circuits, always unplug the device before opening the case. Please refer to the respective device
manuals for full safety information and instruction on how to open the case. Signal wiring changes
external to the case can be made safely while the units are under power.

5. PROGRAMMING YOUR MODBUS DEVICE
OVERVIEW
Modbus digital panel meters, counters, timers and transmitters are easily programmed via their
serial port using Windows-based Instrument Setup (IS) software, which provides a graphical
user interface and is available at no charge. This software allows uploading, editing, downloading and saving of setup data, execution of commands under computer control, listing,
plotting and graphing of data, and computer prompted calibration. Digital panel meters,
counters and timers can also be programmed via their 4-key front panel as explained in their
respective manuals; however, online programming is easier. For Ethernet, please see our
separate Ethernet Manual.
GETTING STARTED WITH INSTRUMENT SETUP SOFTWARE
To install IS software, download the file

The best way to learn IS software is to experiment with it. From the Main Menu, click on
to retrieve (or get) the existing setup data from your device. Click on
Setup
bring up screens which allow you to edit the setup file using pull-down menus and other
selection tools. You can save your file to disk by clicking on
download (or put) your edited file into the device by clicking on
items will only be displayed if the appropriate hardware has been detected, such as the dual
relay option for meters. Pressing the F1 key at any time will bring up detailed help information.
An analog output is defined in two steps. The input to the device is first scaled to a digital
reading in engineering units, and this reading is then scaled to the analog output. The digital
reading is also used for setpoint control and can be transmitted as serial data.

6. MODBUS PROTOCOL IMPLEMENTATION
1. GENERAL
The Modbus capability conforms to the Modbus over Serial Line Specification & Implementation guide, V1.0. Both the Modbus RTU and Modbus ASCII protocols are implemented:
Modbus RTU
Baud Rate........... .............................................. 300, 600, 1200, 2400, 4800, 9600 or 19200
Data Format ....... ........................1 start bit, 8 data bits, 1 parity bit, 1 stop bit (11 bits total)
Parity.................. ............................. None, Odd, Even (if None, then 2 Stop bits for 11 total)
Address.............. ...............................................0 for broadcast, 1-247 for individual meters
Modbus ASCII
Baud Rate........... .............................................. 300, 600, 1200, 2400, 4800, 9600 or 19200
Data Format ....... ...................... 1 Start bit, 7 Data bits, 1 Parity bit, 1 Stop bit (10 bits total)
Parity.................. ............................. None, Odd, Even (if None, then 2 Stop bits for 10 total)
Address.............. ...............................................0 for broadcast, 1-247 for individual meters
2. FRAMING
Modbus RTU
Message frames are separated by a silent interval of at least 3.5 character times. If a silent
interval of more than 1.5 character times occurs between two characters of the message frame,
the message frame is considered incomplete and is discarded. Frame Check = 16 bit CRC of the
complete message excluding CRC characters.
Modbus ASCII
The message begins immediately following a colon (:) and ends just before a Carriage Return/
Line Feed (CRLF). All message characters are hexadecimal 0-9, A-F (ASCII coded). The system
allowable time interval between characters may be set to 1, 3, 5 or 10 seconds. Frame Check =
1 byte (2 hexadecimal characters) LRC of the message excluding the initial colon (:) and trailing
LRC and CRLF characters.
3. ELECTRICAL INTERFACE
Four-wire (plus common) full-duplex or two-wire (plus common) half-duplex RS485 signal
levels are jumper selectable for digital panel meters, counters and timers. A polarization
resistor and termination resistor are also jumper selectable. In case of a long line (greater then
500 ft) to the first device, a termination resistor should be selected for the first device. In case
of a long line length (greater then 500 ft) between the first and last devices, a termination
resistor should be selected for the first and last devices. Never add termination resistors to
more than two devices on the same line. A two-wire, half-duplex RS485 signal level is jumper
selectable for transmitters.

Because the Counter/Timer can provide up to 3 display items during normal operation, it can
Note:
be used to provide additional features when used as a Remote Display. It is possible to send
Remote Data to Item 3 using addresses 006B,C or 006D,E. If the Counter/Timer is set up with
the "Source" menu item set to Item 3, it will make alarm comparisons to its Setpoints using the
Remote Data. Likewise, the Analog Output will respond to the Remote Data if "AnSEt" selects
Item 3 for the Analog Output source and the Display mode (Config Dig 3 = 7).
Address 0069,A sends Remote Data to the display only (any Display mode).
Address 006B,C sends Remote Data to Item 3 only for Alarms and/or Analog Out.
Address 006D,E sends Remote Data to both the display and Item 3.
