M1650, M655 and M1600 PLC
The M1650 and M655 are sixth-generation Micro-Comm controllers similar to the M1550/M555 PLCs,
but with the additional of a built-in Ethernet coprocessor (uLynx) in place of the COM5 Ethernet found
in the older PLCs. The new uLynx Ethernet module provides simultaneous master connections to other
controllers as well as multiple slave connections utilitizing Micro-Comm CTU32, Modbus/TCP and
Ethernet/IP protocols. It also includes a built-in web server for diagnostics.
The M1600 is identical to the M1650 except the Ethernet connection and coprocessor is not included.

Expansion I/O Module Setup
(EAI8 Module)
The EDI16, EDO16, EDO6R, EAI8 and EAO4 modules allow an
RTU to have additional discrete or analog inputs/outputs. These
modules are normally connected to the RTU using the COM3
terminal block or 9-pin port. Both power and communication lines
are provided by the RTU.

Dip switches set both the address of the module and the baud rate
used by the RS-485 connection to the RTU.
ON
1 2 3 4 5 6 7 8
Switches 1-7 set the address:
Module #1 = switches 1-7 off
Module #2 = switch 1 on, 2-7 off
etc.
The baud rate is set using switch 8:
9600 baud = switch 8 off
19200 baud = switch 8 on
The default baud rate used by the RTU is 9600 baud. This can be changed in the RTU Configuration 32
program if necessary. The normal COM3 Mirco-Comm I/O polling loop will take around 2.6 seconds to
update all modules at 9600 or around 0.7 seconds at 19200 baud. Micro-Comm I/O protocol on COM3
currently supports (4) EDI16, (4) EDO16, (4) EAO4 and (2) EAI8 modules.
All modules use Modbus RTU protocol and will be communicated with automatically using the “MicroComm I/O” protocol or can be communicated with manually using the MESSAGE() or MIOMSG()
functions in script.
Note:
The Micro-Comm I/O polling loop was originally designed to extend the on-board physical I/O of an
S4500. It starts with locations that are outside the range of the S4500 on-board I/O: writing DO17-DO80,
AO1-AO16 and reading DI17-DI80, AI17-AI32.

Display Module Operation
The Micro-Comm display module allows the operator to view up to 32 analog levels, 32 discrete input
conditions, 32 discrete output conditions, change up to 32 stop/start setpoints, change all 8 output timer
settings (both on and off delays) , view/change the user variables (X1-X32) and view/change user
memory with up to 128 screens. In addition to these options there is a debug mode available that will let
the operator turn on and off outputs, check inputs and view communications.

General Instructions:
• Use the Up/Down arrows to move between categories (analog level displays, discrete inputs and
outputs, timer settings, stop/start setpoints, user variables and user memory screens)
• Use the Right/Left arrows to move between items (which analog screen, timer output etc.)
• Press ENTER to start entering a value for timers or setpoints.
• Use the number keys to enter values. Use BKSP if you need to backspace.
• Press ENTER when done with each entry.
Special Modes:
• Type .123 to get into the debug mode. Then hit the ENTER key to see a menu of choices.
• Type .456 to get into the view communications screen. All radio communication data will then appear
on the display. Press the up arrow to get out of this mode.
• Type .741 to temporarily go from CTU32 mode to display mode. Note: This will only work if
“hankshake” is disabled ahead of time since the RTS line will normally be off - see setup below.
NOTE: The display communicates with the RTU using a serial cable (9 pin to RJ-11). The protocol
options should be set to 9600 baud, 8 data bits, none parity, echo disabled. These are the factory
defaults. To set a display back to factory defaults, hold down the PERIOD, ZERO and F1 keys during
power up and then press the F1 key to load the defaults. The default for “handshake” is “enabled”
(this will need to be disabled if you plan to use the temporary display mode described above).
To change these parameters, press the PERIOD, ZERO and F1 keys any time after power up. If the
handshake was enabled you will need to temporary provide that (CTS input pin high) in order to get
into the setup menu.

RTU32 Protocol I/O Mapping
The new RTU32 protocol is currently available only by using Message() commands from another RTU32
PLC. When being polled from a C2000 or Card Rack CTU, the older “Enhanced Control Card” protocol
will be used. The table below shows how the physical I/O in the S4500 is mapped for both protocols:

RTU Configuration 32
Program Installation
A new version of RTU Configuration is required for programming the S4500 and later 32 bit PLCs. For
lack of a better name, this new program is called “RTU Configuration 32”. Throughout this manual the
program will be called “RTU Configuration 32” or “RTU Config”.
RTU Configuration 32 currently runs on Windows 7 Pro and later, Linux and Mac OS X 10.7 and later.
To Install the Windows version, follow the steps below:
When upgrading to a new version of the program, go to the Control Panels in Windows and double-click
on Add/Remove Programs. Look through the list and remove any old versions of RTU Configuration.
1) Insert the CD into the CD-ROM Drive or download the setup program.
2) RUN the SETUP program located on the CD-ROM.
3) Follow the prompts and do a typical install.
4) After installation, the program icon will appear in the Start menu’s Program list.
When running the configuration program for the first time you will need to look at the serial port setup
screen to make sure you have the correct COM port number selected. The port setup is located in the
program’s “Edit - Preferences...” menu. Connection to the PLC is by means of a Null-modem cable from
the computer’s RS-232 port to the PLC’s COM2 port (display port).
- 35 -
RTU Information Screen
The RTU Information screen contains version, date, checksums, user information, address switch settings
as well as a picture of the RTU. This information about the RTU will be available after the user has read
the Personality Module. The Job Name and Site Name fields can be changed if necessary and the User
Name and Last Programmed will reflect who made the most recent change. All the “User” information is
sent to the RTU whenever the personality data is programmed.
- 36 -
Configuration Parameters
The screen below shows a sample RTU Configuration dialog box. This screen is where all the operational
parameters stored in the Personality Module can be changed (radio communications parameters, output
timer settings, automote control settings and stop/start setpoints).
To retrieve the personality data from an RTU, click on the blue down arrow icon or select Read
Personality Data from the Transfer menu. After making changes, click the blue up arrow icon or select
Program Personality Data from the Transfer menu.
- 37 -
RTU Configuration Parameters
Model Number
The model of the RTU being configured is selected and shown here.
Protocol
The protocol selection for the radio communications port (COM1). Options include Micro-Comm
RTU32, DF1 Half-Duplex Slave, DF1 Half-Duplex Master, DF1 Full-Duplex, DF1 Radio Modem,
Modbus RTU Slave, Modbus RTU Master or Modbus/TCP.
Baud Rate
This selects the speed for the radio communications port (COM1). 110, 300, 600, 1200, 2400, 4800,
9600, 19200, 38400, 57600 and 115200 bps are supported.
Parity
Parity checking mode (Even, Odd or None).
Data Bits
The number of data bits used by the radio port (5, 6, 7 or 8).
Stop Bits
The number of stop bits used by the radio port (1 or 2).
PTT
Time in milliseconds that will occur after the radio is keyed and before the data is sent out the radio port.
This should normally be set to 250 msec or more for Micro-Comm RTU communications using conventional radios. Data radios will allow for much lower PTT times (50 msec or less).
Enable Modem
When this option is checked, the RTU will turn on the internal 600 (or 110) baud radio modem. Leave
this box un-checked when using an external radio modem. Note: The S4500 and M1500 RTUs do not
have hardware support for this option. Only M550 and later RTUs.
Ant. Outputs
The range of 8 discrete outputs to use when a remote is doing Antenna/Radio switching. RTU32 protocol can only specify an 8 bit mask so this selection allows it to be applied to outputs 1-8 or 9-16.
Ant. Default
Discrete ouput number to leave on for Radio #1 when doing Antenna/Radio switching at a remote.
Station #
For use with Modbus or DF1 protocols ONLY. This sets the station # for this RTU as used by the protocol on all of the communication ports.
SCode
For use with Micro-Comm RTU32 protocols ONLY. This sets the “System Code” for this RTU that the
central must use in order to communicate with us. The central system code is selected in the message
function (MSB of station address = 1-8). This can help to isolate systems on the same frequency from
each other. Usually this will be set to “None”.
COM2 Protocol
Communication protocol used on COM2. This can be Micro-Comm Display, Micro-Comm RTU32,
Micro-Comm CTU32, DF1 Half-Duplex Slave or Master, DF1 Full-Duplex, DF1 Radio Modem,
Modbus RTU Slave or Master, Modbus/TCP or Web Server.
COM2 Baud
This selects the speed for the COM2 port.
The default is 9600 baud for compatibility with the Micro-Comm Display Module.
COM2 PTT
Time in msecs that will pass after RTS is turned on and before data is sent out COM2.
The default is 0 which will leave the RTS turned on all the time.
COM3 Protocol
Communication protocol used on COM3. This can be Micro-Comm I/O, DF1 Half-Duplex Slave or
Master, DF1 Full-Duplex, DF1 Radio Modem, Modbus RTU Slave or Master, Modbus/TCP, MicroComm Display, Micro-Comm RTU32 or Micro-Comm CTU32.
COM3 Baud
Communications speed for the Micro-Comm I/O modules or for Modbus RTU / DF1 communication.
The default is 9600 baud.

COM4 Settings
The options for the M555 and M1550 COM4 port are similar to that of COM1 with the additional “Mode” option. There is also
an additional protocol option for use with the uLynx Ethernet coprocessor.
Other Tabs
Timer Settings
The timer settings control how long the RTU will wait to energize or de-energize a relay output when it has been told to come
on or go off. These timers will always be used regardless of the mode of operation - Micro-Comm CTU control, Script Language, Modbus or DF1.
Stop/Start Setpoints 1-32
These setpoints can be labeled and accessed from the Micro-Comm Display module and then used in script for control.
Stop and Start setpoints are scaled using the analog selected in the Stop/Start Labels screen.
Use 8-bit Remote Setpoints
This option will force the remote setpoint protocol (used by SCADAview) to use 8-bit (LSB) values. This may be required if
the central is a C2000 or earlier.
Misc.
Pulse Dividers
These sets the number of pulses that must occur before the pulse input counter is incremented.
Normally this will be set to 1.
Expanded Data Station
When this is checked, the primary address will respond with local expanded data when using CTU32 protocol.

Ethernet (COM5) Settings
The options for the M555 and M1550 ethernet port are configured with the screen shown below:
Protocol
The protocol selection for the Ethernet Port (COM5). Options include Micro-Comm RTU32, DF1 HalfDuplex Slave, DF1 Half-Duplex Master, DF1 Full-Duplex, DF1 Radio Modem, Modbus RTU Slave,
Modbus RTU Master, Modbus/TCP, Micro-Comm CTU32, Web Server, EtherNet/IP SLC and EtherNet/
IP CLX (compact logix).
Mode
This selects whether COM5 will be a TCP Server, TCP Client or UDP Mode (client/server). Changing
this selection will change what other options are visible.
IP Address
TCP/IP Address of the M1550 PLC on the network.
Subnet Mask
Selects the class of the local network (usually either 255.255.255.0 or 255.255.0.0)
Gateway
The address of the local network router (if any).
Reverse-Poll
Enabling reverse-poll when using CTU32 protocol will allow multiple computers (up to 4 using client
mode) to receive status updates.
Local TCP Port
Port number used when we are a TCP Server. Our default is 4001. It will be forced to 44818 when
using EtherNet/IP. It should also be changed to 502 when using Modbus/TCP protocol.
Max. Connect
The maximum number of clients that can connect to us when we are a TCP Server (1 - 4).
Destination IPs
If the mode is a TCP Client, these are the addresses and port numbers that the PLC will connect to.
Local Listen Port
Port number on which we will receive data from the other PLCs when using UDP Mode. This can be
the same port as used for transmitting data. (4001 is our default).
UDP Ranges
When using UDP Mode, these ranges of IP addresses and port numbers will all be sent data when the
PLC transmits. Note: Do not include the PLC’s own IP Address in these ranges.
The “Network Search” button will scan the local network for Micro-Comm PLCs.

Analog Labels and Scaling Factors
To change analog labels and scaling factors, click on the blue water tower icon or select “Display Labels”
from the View menu. The labels and scales are retrieved/sent to the RTU during reading/writing of the
personality module configuation data.
Up to 32 analog levels can be displayed and they will always appear in the order entered in the setup
screen. If an analog label is left blank it will not show up on the display.
When analog levels are displayed, the offset is first added to the raw analog value and the result is then
multiplied by the range value. (This matches the Micro-Comm SCADAview program). A Range/Preset
calculator (shown below) can be displayed by right-clicking and selecting the menu option.
- 41 -
Output Timer Labels
To change the 20 character output timer display labels, click on the toolbar clock icon or select “Display
Labels” from the View menu. The labels are retrieved/sent to the RTU during reading/writing of the
configuration data. These labels are normally used for pumps and provide both ON and OFF delays
entered on the Micro-Comm Display Module.
Note: Lines where the label is left blank will not be accessible from the Display Module.
- 42 -
Stop/Start Setpoint Labels
Stop/Start labels are used on the Display Module to allow the operator to change operational parameters
such as Pump Stop/Start setpoints, High/Low alarms and Pump Restore/Cutoffs. Along with the 20
character label is a selection for what type of setpoint (Stop/Start, High/Low etc.) and which analog input
# will be used for scaling and units.
Note: Lines where the label is left blank will not be accessible from the Display Module.
- 43 -
X Variable Labels
User variables are the 16-bit unsigned integer X1-X32 script language variables that can be used for any
purpose. By entering a label in the User Variable Labels setup screen, the current value will be shown and
can be changed on the Display Module.
- 44 -
Discrete I/O Labels
Labels for both 32 discrete inputs and 32 discrete outputs are user defined. These labels may be used to
display pump calls, pump runs, valve positions, alarms etc. A 12-character label is used to name the input
or output along with a 6-character ON label and a 6-character OFF label to describe the on or off state. If
the input or output name is left blank it will not appear on the display and if no discretes are labeled the
display will just skip over the entire section (inputs or outputs).
Note: Two special ON labels are reserved for the discrete outputs: “CRF” or “CRFD” will display the
current state of a pump output as “CALL”,”RUN”,”FAIL” or “CALL”,”RUN”,”FAIL”,”DSBL”.
- 45 -
User Memory Screens
User memory screens allow for display and entry of data stored in user memory (locations 0-8999). The
raw data type can be a 16-bit unsigned integer (1 user memory location), a 32-bit unsigned integer (2
consecutive user memory locations) or a 32-bit floating point number. This data can then be displayed as
numeric values, discrete labels or binary numbers given various parameters.
The user memory screens are accessed by arrowing all the way down to the bottom row of the MicroComm display. The left and right arrows will then select the desired user memory screen.
- 46 -
User Memory Table
The User Memory Table screen provides the capability of reading and updating all user memory locations
as well as saving and loading a comma seperated (.CSV) database file. This file could then be used for
data logging/trending or saving a backup copy of important data such as flow totals, runtimes etc. The
screen shown below is accessed from either the Utilities menu or by clicking on spreadsheet looking icon
on the toolbar. Data is updated “live” unless the Pause button is depressed. An panel located on the right
side of this window shows all information about the selected memory location.
Special color coding and help text is used to show stations, groups, other message types and user memory
variables. (green=groups, blue=stations, purple=user memory variables and yellow=other messages)
Right-clicking on this screen will bring up a menu with options to “Find...”, “Read User Memory”,
“Program User Memory”, “Save CSV File...” and “Load CSV File...” etc. Double-clicking on a cell will
put it into edit mode and a new values can be entered (press Enter to send).
NVRAM Database
In addition to the User Memory Table, there is also a very similar NVRAM Table window which can
be used to download and save data from the RTU’s personality module. This could be used for longterm data logging since it currently supports 65000 words of data. The script commands NVREAD(),
NVWRITE() and NVCOPY() are used to manage this data.
- 47 -
RTU Script Language Editor
To enter or edit the Script Language Code, click on the script icon in the tool palette or select “Script
Editor” from the View menu.
Script language can be retrieved from the RTU by clicking the Read button shown at the bottom of the
editor window or by selecting Read RTU Script from the Transfer menu.
Lines starting with a single quote character are comments and do not get sent to the RTU when
programming. Comments are only saved in the .S5C configuration file.
After entering lines of code the user can click the Check button to make sure the syntax looks ok and to
see how many bytes of code have been used. Currently the main script code can’t be larger than 16895
bytes.
The code is then programmed into the RTU’s personality module by clicking the Program button or by
selecting “Program Script” in the Transfer menu.
Script subroutines are edited by selecting the subroutine number from the list in the lower-left corner of
the screen. Each subroutine can be read, programmed and checked separately using this editor. Currently
each subroutine can be up to 2110 bytes.
- 48 -
Commented Script / Revision Editor
If the option “Use Commented Script for Revision Notes” is turned on in the preferences, this screen will
be filled in with the current commented script including all subroutines. It can then be programmed into
the personality module with the “Program” button. The user will also then be asked if the commented
script should be programmed whenever the configuration or compiled script is programmed. Commented
scripts can be read back from an RTU and imported into the actual script by right-clicking and selecting
the “Import Commented Script” menu option.
If the option “Use Commented Script for Revision Notes” is not turned on in the preferences, this screen
can be used to edit general purpose Revision Notes for the RTU. The Read and Program buttons are
used to retreive or store the notes into the personality module. Revision notes are also saved in the .S5C
configuration file.
- 49 -
Data Table Viewer
The Data Table Viewer screen allows the operator to see and change I/O variables, User variables and
the Stop/Start setpoints in real-time when connected to an RTU. This screen can be very useful when
debugging script language code. The User Memory data table can display all user memory (a range of 64
locations at a time) and will allow for changing these values.
Analog inputs and Stop/Start setpoints are displayed as raw 12-bit numbers (0-4095) or can optionally be
scaled based on the range/offset values entered in the analog setup screen. Pressing the “S” key on this
display will toggle scaling on and off. Discrete inputs and outputs are shown as either 1 or 0 (on or off).
When the “Force I/O” option is selected, the I/O variables shown in red may be changed to the desired
value by clicking on the readout box, typing a new value and pressing enter. When the “Disable Script”
option is also checked, the script will stop running and any I/O that it was controlling can then be forced.
- 50 -
Display Module Emulator
The display module is an optional hardware component to a Micro-Comm RTU which allows an operator
to see levels and change setpoints. While programming with RTU Configuration 32 software, the operator
can use the Display Module Emulator screen to see what the display module would show. This can be
very useful since both the display module and the programming software may be using the same com port
on the RTU.
- 51 -
Debug Terminal
The Debug Terminal screen allows the user to interact directly with the RTU over the programming port
(COM2-COM5) or with other third-party serial equipment. It will display incoming data using ASCII,
Modbus or DF1 mode based on the “Display Mode” selection in the lower-left hand corner of the screen.
Protocol analysis of master messages (requests) can be done by selecting “RTU32-Decode”, “ModbusDecode” or “DF1-Decode”.
Data logging can also be done by clicking on the “Log Data...” button and typing in a file name.
Communications on COM 1-5 can be monitored by clicking the appropriate button.
The “Debug” button will enter a hardware debugging mode where outputs can be turned on and off,
inputs can be read, the clock can be set etc. Press the Enter key when in this mode to get a help menu.
