User’s Manual
1. Introduction
FBs-CMGSM (CMGSM for short) is communication module for FATEK PLC systems
FBs-xxMC. CMGSM uses the GSM network to transfer the data. CMGSM is based
on the quad band GSM module (850/900/1800/1900 MHz). CMGSM is backed
up by Li-Ion accumulator.
CMGSM offer three different ways of communication with connected PLC.
The first one is monitoring and remote control of PLC via SMS. CMGSM reads
periodically PLC registers containing a flag to send SMS, if the flag is set, CMGSM
reads destination phone number and string of characters (text), sends SMS and
clears the flag. If there is a SMS received by CMGSM, it is written into PLC registers
including another flag “SMS received” to be processed by PLC program. At the end
the PLC program clears this flag. So these operational SMS must be processed by
PLC program both on SMS reception and SMS sending. Some status and event SMS
are predefined in CMGSM (e.g. “Connection to PLC failure”) and only the destination
phone number have to be set in PLC registers.
The second way of communication with PLC via CMGSM is dial up data transfer
via GSM network (CSD). The connection can be only incoming for CMGSM, that
may be initiated from a control center for the purpose of remote system analysis
and PLC software tuning and modification by WinProladder SW.
The third way of CMGSM communication over the GSM network is GPRS data
connection using TCP/IP protocol. CMGSM opens the connection in TCP client
mode. Any SIM card, that can provide internet connection over the GSM network,
can be used. CMGSM connects to IP address and port specified in from PLC. It is
important to notice, that the connection can be opened in direction from CMGSM to
PC (server) only. PC cannot open a connection to CMGSM because CMGSM has no
server implemented and usually does not have public IP address. GPRS has special
data transfer properties (data grouping, data transfer delay 1 ... 10 seconds), which
are not suitable for WinProladder SW. WinProladder must use dial up data
transfer (so called CSD) only.

4. Function of the device
4.1 SMS
One of the primary functions of the CMGSM is to send and receive SMS messages.
There are 2 kinds of SMS, which have different functions and purposes:
SMS for and from PLC FATEK, see chapters 4.1.1. and 4.1.2
Service SMS commands processed by CMGSM, see chapter 4.3
Outgoing SMS from PLC FATEK are sent by PLC program, that writes the text and
destination phone number into PLC registers and orders CMGSM to send the
message by write special value to another register ( SendFlag ). CMGSM sends SMS
and writes result of the sending to PLC register ( SendFlag ). Incoming messages for
PLC FATEK are received by CMGSM and the text and origin phone number are
written into PLC registers. Subsequently in another register ( RecvFlag ) is written
value, that signalizes new received SMS. PLC program analyzes the registers and
deactivates flag RecvFlag . All the SMS structure and security features must be done
by PLC program, including confirmation, that SMS was received, if required.
SMS messages, which contains characters “#!” (hash and exclamation) followed by
access code, are sent and received by CMGSM itself and their function, structure
and security features cannot be changed by user or PLC program. Incoming SMS of
this kind are described in chapter 4.3 Service SMS Commands and are used to get
information about CMGSM status, to reset CMGSM or to get current CMGSM
configuration. Outgoing SMS of this kind are described in chapter 4.5 Events . Events,
it is information about emergency status of CMGSM module like lost communication
with PLC. These events are sent to a predefined phone number ( Master in
configuration).
4.1.1 Sending a SMS
CMGSM periodically tests the first register of the Send Record , standard base is
D3800. The Send Record is an area in PLC registers which must be filled by program
in PLC in order to send a SMS message. For structure of the record see the following
table.

If length of phone number is exactly 20 characters (or 160 characters of text) the
character 0x00 at the end is omitted!
CMGSM contains a queue of up to 100 SMS messages. After the queue is full all
other SMS messages are discarded. If a power failure occurs all received messages
in the queue are lost. Base of Recv Record (D3700) may be changed to another D
or R register via configuration key REGRECV. No other registers are changed than
the necessary ones.

4.2 GSM Data Connection (Data Call, CSD)
Data connection can be established anytime, even if GPRS communication is in
progress.
Warning
There is no security mechanism against unauthorized data connection to
PLC. So it is highly recommended to set security in PLC (password).
4.3 Service SMS Commands
Received SMS message with string ‘#!’ and password at the beginning are
considered to be service SMS commands . These messages are not forwarded to PLC,
but they are processed in CMGSM. Device will check for a valid access code (ACODE
parameter in configuration) and if the access code is valid, the message is searched
for keywords. Only one keyword in every SMS is executed.
Example of this SMS:
#!1234 INFO
#!998877 CONFIG
Table of all keywords:
Keyword
Description

IN1=off
OUT2=off
CSD=no connection
GPRS=no connection
PLC=connected
CMGSM v8.2
RESET
Device will respond with confirmation SMS and restart itself. PLC is
not affected.
This command is used after change of configuration in PLC register
to accept the changes by CMGSM.
CONFIG
Device will respond with current configuration. (Current
configuration is a default configuration with some values changed by
configuration string in PLC, see Chapter 5 –Configuration.)
FACTORY
CMGSM will respond with confirmation SMS. CMGSM will write
default configuration to attached PLC and restart itself.
ON
Activate digital output OUT2
OFF
Deactivate digital output OUT2
4.4 TCP over GPRS
One of the primary functions of this device is to establish and maintain TCP
connection from PLC to a server. In order to achieve this goal FBs-CMGSM has to
make following steps after power up:
Establish connection to PLC via serial port. Parameters of the serial port are: 9600
baud, 7 data bits, EVEN parity, 1 stop bit, no hw handshake (it is default FATEK
settings for all serial ports), address 01h.
After power on the FBs-CMGSM will proceed steps:
Read configuration from PLC register D3900 –D3999.
Login to the GSM network, using PIN from configuration.
Attach to GPRS, using APN, USER and PASSWD from configuration.
Establish and maintain TCP connection to SERVER on port PORT.
CMGSM will try indefinitely to read configuration from PLC at the beginning. If there
is no serial communication between CMGSM and PLC device will not login into the
GSM network! If there is no configuration in PLC or the configuration is damaged or
other problem occurs CMGSM writes default configuration into the PLC.
GPRS can be controlled and monitored via set of registers in PLC and via
configuration:

5. Configuration
5.1 How to
Configuration for CMGSM is located inside PLC Fatek. Range of internal PLC registers
D3900 –D3999 is used. Configuration itself is a string of characters. This string is
created via WinProladder (software from PLC FATEK manufacturer), see following
images. This range of registers cannot be used for any other purposes!
Step 1 –Right click on Table edit - ASCII Table
and select “New ASCII Table”
Step 2 –Enter Table Name „cfg“ and Table starting address „D3900“.
Then click “OK”.
Step 3 –Enter configuration string
“CMGSM3;PIN=7608;ACODE=998877;$”into field “ASCII Editor”and
click on button “Output Preview”. !!! Warning: Change PIN according your
real SIM card !!!
Step 3 (GPRS) –Enter configuration string
“CMGSM3;PIN=7608;APN=internet;SERVER=test.server.com;PORT=5700
;ACODE=998877;$” into field “ASCII Editor” and click on button “Output
Preview”. !!! Warning: Change PIN according to your real SIM card !!!
PLC1.ir

140903 FBs-CMGSM User's Manual EN v3-04 Page #5 of 7
Step 4 –Select “Non Output Format” and click “OK”.
Step 5 –Configuration string is now black. Click “OK”.
Step 5 (GPRS) –Configuration string is now black. Click “OK”.
Step 6 –Result
Configuration is read after power up and only once. If you change configuration (for
example by WinProladder and second serial port), it is not read automatically. You
have to restart CMGSM. CMGSM will try to log in the GSM network without PIN if no
configuration in PLC is found. (In this case SIM card without PIN authorization is
requested.)
Configuration string is very simple. For example:
CMGSM3;PIN=7608;ACODE=998877;MASTER=[phone];$
For easy understanding this string says:
CMGSM3 –It is a configuration for CMGSM.
PIN=7608 –PIN code of the SIM card in order to register into the GSM
network.
ACODE=998877 –Access code for Service SMS Commands is 998877
MASTER=[phone] –Warning SMS is sent to this phone number
in case of any event. For example “Connection to PLC failure.”when
communication between CMGSM and PLC is lost or “IN1 activated (L-
>H).”when digital input IN (IN1) is activated respectively “IN1 released
(H->L).”when digital input IN (IN1) is deactivated.
Example of configuration string for GPRS:
CMGSM3;PIN=7608;APN=internet;
SERVER=test.server.com;PORT=5700;ACODE=998877;$
This string means:
CMGSM3 –It is configuration for CMGSM.
PIN=7608 –User PIN code of ‘7608’ for SIM card in order to register
into the network.
APN=internet –Access Point (APN) is needed in order to use GPRS
service in GSM network. In this example APN is ‘internet’.
SERVER=test.server.com –It is a name of a server, to which CMGSM
will connect. (Using TCP connection.)
PORT=5700 –Use TCP connection to port 5700
ACODE=998877 –Access code for SMS control is 998877
General format of these messages is following:
CMGSM3;KEY1=VALUE1;KEY2=VALUE2;...[;]$
Part ‘CMGSM3’ at the beginning of the string is mandatory. It is a stamp of validity.
Acceptable keys are shown in table below. Unknown keys are ignored, no spaces
are allowed inside keys or values. Order of pairs is not important. Keys are not case
sensitive, values are case sensitive. Maximum length of configuration string is 200
characters. At the end of each part MUST be character ‘;’ (semicolon), after last pair
MAY be character ‘;’ (semicolon) and MUST be character ‘$’ (dollar).

7. Usage Scenarios for GPRS
7.1 Explanation of Important Terms
Term
Description
GPRS
The way how to transfer data through the GSM network. It is
charged according to transferred bytes (and not per minutes) and is
much more suitable for remote monitoring than data connection
(CSD).
TCP/IP
It is protocol which is used while communicating through GPRS.
(Like Fatek protocol is used to communicate between computer and
Fatek PLC).
TCP
It is one of protocols in TCP/IP family used with CMGSM. It may be
imagine as a bidirectional stream of bytes through the Internet and
the GSM network from your computer to a Fatek PLC
Firewall
It is a security device. It located between you LAN and Internet.
Main purpose of the Firewall is to protect your LAN against an attack
from Internet.
Port
It is a number of a service in your computer. Complete address
needed to connect your computer is composed from IP address and
Port number and may be seen as 11.22.33.44:5700 (IP-
ADDRESS:PORT).
7.2 Simple Use
We recommend this scenario for your first step with CMGSM.
Internet
Firewall
Your computer in LAN
of your company
GSM Network
LAN
FBs-
CMGSM FATEK PLC
PWR
COMM
You need to prepare following items in this scenario:
External (WAN) IP address of your firewall. Rest of the Internet sees you
with this IP. Warning: it is NOT your IP address in LAN (i.e. 10.0.0.25).
Your external IP address may be obtained from various WEB sites, i.e.
http://www.whatismyip.com/.
A redirection of port 5700 from external side of your firewall to your
computer.
Cooperation of your IT department will be necessary for all of these items.
We offer simple program that acts like a server. CMGSM connects to this server.
This program is only a demonstration for one connection and elements X0-X3 and
Y0-Y3. It may be obtained from our WEB site (www.seapraha.cz).
Details: Program listens on TCP port 5700 for incoming connection. Port 5700 is
default port where CMGSM connects to. Program periodically queries status of
inputs X0-X3 from remote station. You can change any of output Y0-Y3 by click on a
check box Y0-Y1.

9. FAQ
CSD (GSM data) connection cannot be established –1) check
power supply, 2) check indication LED on device, 3) are CSD connections
available on your SIM card? Ask provider, 4) check GSM signal quality on
your mobile phone near the device. At least 50% signal is recommended.
No reply to Service SMS Commands –1) check power supply, 2)
check indication LED on device, 3) check configuration (is access code
correct?), 4) try to send SMS from your mobile with SIM card in the
device. (Note: LED RCV and SND are not used for Command SMS)
Some special characters are not correctly transported by SMS –
Try to use so called 7 bit SMS (160 characters) and only basic ASCII
characters (0-127)
No communication with PLC –1) check power supply for PLC, 2)
check COM port settings in WinProladder. It MUST be 9600 7E1, address
01h.
GPRS connection cannot be established –1) check power supply, 2)
check communication with PLC Fatek, 3) check configuration, 4) check if
it is possible from another computer connected to the Internet to
connect to your server (may be firewall is wrong configured).
GPRS connection is not working during CSD connection –This is
the feature of GSM module. GPRS connection is restored automatically
after CSD connection is finished.
Communication is OK but real outputs Y0-Y3 do not reflect
commands –1) PLC FATEK must be in Run mode. Use WinProladder to
run PLC.
Communication is OK but inputs X1-X3 do not show correct
value –1) PLC FATEK must be in Run mode. Use WinProladder to run
the PLC.
Some parameters in the FATEK configuration are not
functioning –Please check if there is no “$” character before these
parameters (e.g. “CMGSM3;$PIN=7608; ACODE=998877;$”) because
CMGSM reads the configuration until the first “$” character.
