CHAPTER 0PRODUCT OVERVIEW
IMPORTANT Basic configuration to install the hardware and connect the Protocol Converter to the network
is available from RLE. However, the Protocol Converter is an advanced product, and you must
have in-depth knowledge of the Modbus, BACnet, and SNMP protocols to complete the
configuration.
1.2. Product Description
TheProtocol Converter receives one or more protocol types and outputs up to three protocol
types. The Protocol Converter can receive data from slave devices using Modbus RTU,
Modbus TCP/IP, BACnet/IP, or SNMP (integer data). The Protocol Converter can then be
polled by a master unit via SNMP, Modbus RTU, Modbus TCP/IP, or BACnet/IP. In addition,
the Dual Port Protocol Converter can be configured as a slave (Note: only as a slave) and
polled by a master unit via BACnet MS/TP.
There are two versions of the Protocol Converter: the “standard” version, and the “dual port”
version, which contains two additional EIA-485 ports for expanded connectivity and
communication.

CHAPTER 0MODBUS COMMUNICATIONS
This chapter describes the Modbus communication protocol as supported by the Protocol
Converter Wireless System. The content includes details and information on how to configure
the Protocol Converter for communications via Modbus network.
4.1. Implementation Basics
C HAPTER
The Protocol Converter is capable of communicating via the half-duplex EIA-485 serial
communication standard. The Protocol Converter is configured to act as a slave device on a
common network. The EIA-485 medium allows for multiple devices on a multi-drop network.
The Protocol Converter is a slave only device and will never initiate a communications
sequence.
4.1.1 Modes of Transmission
The Modbus protocol uses ASCII and RTU modes of transmission. The Protocol Converter
supports only the RTU mode of transmission, with 8 data bits, no parity and one stop bit.
Every Modbus packet consists of four fields:
♦ Slave Address Field
♦ Function Field
♦ Data Field
♦ Error Check Field (Checksum)
4.1.1.1 Slave Address Field
The slave address field is one byte in length and identifies the slave device involved in the
transaction. A valid address range is between 1 and 254. The slave address is set on the
Modbus Device section of the Configuration page.
rletech.com Protocol Converter User Guide 53
Modbus Communications
4.1.1.2 Function Field
The function field is one byte in length and tells the Protocol Converter which function to
perform. The supported functions are 03 (Read 4xxxx output registers).
4.1.1.3 Data Field
The data field of the request is a variable length depending on the function. The data fields for
the Protocol Converter are 16-bit registers, transmitted high order byte first (big-endian)
4.1.1.4 Error Check (Checksum) Field
The checksum field lets the receiving device determine if the packet has transmission errors.
The Protocol Converter RTU mode uses a 16-bit cyclic redundancy check (CRC-16).
4.1.2 Exception Responses
If a Modbus master sends an invalid command to the Protocol Converter or attempts to read an
invalid register, an exception response is generated. The response packet will have the high
order bit of the function code set to one. The data field of the exception response contains the
exception error code.
Table 4.1
Code Name Description
01 Illegal Function The function code is not supported
02 Illegal Data Address Attempt to access an invalid address
03 Illegal Data Value Attempt to set a variable to an invalid value
Exception Codes
4.2. Packet Communications for the Protocol Converter
This section covers the registers with the name and a brief description of each.
4.2.1 Function 03: Read Output Registers
To read the Protocol Converter parameter values, the master must send a Read Output
Registers request packet.
The Read Output Registers request packet specifies a start register and the number of registers
to read. The start register is numbered from zero (40001 = zero, 40002 = one, etc).

CHAPTER 0LOAD FIRMWARE & CONFIGURATION
FILES
You can perform the following firmware and configuration operations for the Protocol
Converter:
♦ Load different firmware to the Protocol Converter. RLE occasionally updates the firmware
to add enhancement or fix errors. Firmware updates are available on the RLE website at
www.rletech.com. Download appropriate firmware to an accessible place to upload to the
Protocol Converter via MIME or TFTP through a LAN connection. Firmware files have a
.bin extension.
♦ Make a backup of your custom configuration or copy the same configuration to several
Protocol Converters rather than having to change the settings manually on each unit. The
configuration settings are contained in a .cfg file.
♦ Make a copy of the configuration for a device so you can copy that configuration to other,
identical devices. The configuration settings for a device are contained in an .xml file.
A.1. Load Flash Firmware Using MIME
To update the firmware for the Protocol Converter using the MIME (multipurpose Internet
mail extensions) standard:
1 Go to the RLE website at http://www.rletech.com.
2 Locate the firmware (a .bin file) for the Protocol Converter. Using the same filename, save
it to a local disk.
IMPORTANT Do not change the name of the firmware file when you save it. Otherwise, the Protocol
Converter will not recognize the file.

Troubleshooting the Protocol Converter
1 Check with a DVM (Digital Volt Meter) for AC or DC
input power on the lower left hand terminal block on the
Protocol Converter. If no voltage is present at terminal
block, check the circuit breaker or power supply that
powers the Protocol Converter.
2 If voltage is present contact RLE Technologies for
further troubleshooting.

B Troubleshooting
Problem Action
Unable to see the web page
Slave units are showing loss
of communication.
1 Verify that the Protocol Converter is powered up and
running. You will see lights on the RJ45 (Ethernet) port
illuminated and flashing. If no lights are illuminated on
the unit, check for power to the unit. If lights are
illuminated and flashing, go to step 2.
2 Connect a serial cable up to the Protocol Converter
console port. Once connect and your terminal emulation
program is running, type ip and then press enter, this will
display the current IP address set to the unit. Verify it is
the correct address. The same can be done for viewing
the Net Mask number by entering nm and then press
enter. For viewing the Default Gateway type dg and then
press enter. Correct any information that is wrong. If the
information is correct, go to step 3.
3 With the serial cable connected and your terminal
emulation program open, you can enter an address to
have the Protocol Converter ping to. Get a known good
address and the type ping <one space> ip address and
then press enter. Example: ping 192.168.1.1, if a ping
response is not established, get with the IT department
and make sure the patch cord being used is good, and
then have the network switch port checked to make sure
it is activated. If a ping response is established, call your
local sales representative or RLE Technologies
technical support department.
1 Check the Device Configuration in the Protocol
Converter and make sure the proper addressing is
assigned.
Table B.1
a Modbus-RTU/485: The device address is set to the
proper RTU address and the 485 communications
line is wired properly.
b Modbus TCP/IP: The Proper device address and IP
address has been assigned. Modbus TCP/IP
communications requires port 502 of that IP address
to be enabled/open. Check with IT to make sure there
is not a firewall or port blocking on port 502.
c SNMP: Check the IP address and community that
was configured on the Protocol Converter for
communication. Port 161 of the IP address is used for
SNMP get data. Check to make sure this port is open.
d BACnet: Check the IP address and device number
configured on the Protocol Converter. The default port
used for BACnet data is port 47808. Check with IT to
make sure this port is open for communication on the
network.
