FBs-CMGSM, B1-CMGSM
User’s Manual
1. Introduction
FBs-CMGSM and B1-CMGSM (CMGSM for short) are communication modules for
FATEK PLC systems FBs-xxMC and B1-xxM. 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 ( and writes result of the sending to PLC register (
SendFlag
SendFlag
). CMGSM sends SMS
). 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 ( value, that signalizes new received SMS. PLC program analyzes the registers and deactivates flag
Master
RecvFlag
in configuration).
. 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

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
FBs-CMGSM User's Manual EN v3-07.doc
Table of all keywords:

CMGSM: NETWORK=Vodafone CZ 77%
IN1=off
OUT2=off
CSD=no connection
GPRS=no connection
PLC=connected
CMGSM v8.2
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.
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.)
CMGSM will respond with confirmation SMS. CMGSM will write default configuration to attached PLC and restart itself.
Activate digital output OUT2
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 FBsCMGSM 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 FBsCMGSM 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:

*2) ModemTime is available in CMGSM with sw. version 2.03 and higher.
*3) CMGSM reads out the local Time and date (NITZ) from the GSM network (if NITZ is available depends on the GMS operator) and approx. 1 per 10 seconds sends this information do PLC registers. The format of ModemTime is similar to PLC registers in
RTC (Calendar).
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;$” into field “ASCII Editor” and click on button “Output Preview”. !!! Warning: Change PIN according your real SIM card !!!
FBs-CMGSM User's Manual EN v3-07.doc Page #4 of 7
Step 3 (GPRS) – Enter configuration string
“CMGSM3;PIN=7608;APN=internet;SERVER=test.server.com;PORT=5700
;ACODE=998877;$” into field “ASCII Editor” and click on button “Output
Preview”. !!! Warning: Change PIN according to your real SIM card !!!
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=+420777777497;$
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=+420777777497 – 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 ‘$’ (dolar).

7. Usage Scenarios for GPRS
7.1 Explanation of Important Terms
Term Description
GPRS
TCP/IP
TCP
Firewall
Port
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).
It is protocol which is used while communicating through GPRS.
(Like Fatek protocol is used to communicate between computer and
Fatek PLC).
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
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.
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.

CMGSM3 – It is configuration for CMGSM.
PIN=7608 – PIN code 7608 for SIM card in order to register into network.
REGSEND=D1000 – Begin of the
Send Record
.
[default Access code for SMS control is 1234]
5.5.3 Only CSD (without GPRS)
Configuration string:
CMGSM3;PIN=7608;$
Translated for human this string says:
CMGSM3 – It is configuration for CMGSM.
[default Access code for SMS control is 1234]
5.5.4 SIM without PIN, GPRS connection
Configuration string:
CMGSM3;APN=internet;SERVER=test.server.com;PORT=5700;AC
ODE=998877;$
Translated for human this string says:
CMGSM3 – It is configuration for CMGSM.
APN=internet – Access Point (APN) is ‘internet’.
SERVER=test.server.com – Connect to ‘test.server.com’
PORT=5700 – Use TCP connection to port 5700
ACODE=998877 – Access code for SMS control is 998877

Firewall
LAN
PWR
FBsFATEK
Your computer in LAN
CMGSM
COMM
PLC of your company
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
It’s not possible to reset CMGSM using FUNC button – it’s necessary to hold the button FUNC pressed at least 2 seconds.
CSD (GSM data) connection cannot be established – 1) check power supply, 2) check antenna, 3) check indication LED on device and compare it with the manual, 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 the power supply, 2) check antenna, 3) check indication LED on CMGSM and compare to the manual (Note: LED RCV and SND are not used for Command SMS), 4) check configuration - is the access code ACODE correct? 5) Insert the
SIM card from CMGSM to you mobile phone and try to send SMS and receive SMS and voice call.
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 PLC power supply, 2) check
Port3 (FBs-xxM) or Port1 (B1-xxM) settings using WinProladder. It MUST be 9600 7E1, address 01h. 3) Check that no Analog or Communication module is added to WinProladder project.
Is it possible to use B1-CMGSM simultaneously with Analog or
Communication module? – Not at the moment, but we prepare
“Autodetection”. In the future B1-CMGSM will connect to PLC through
Port1 or Port2 depending on usage of Analog or Communication module.
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 PLC.

Communication is OK but inputs X1-X3 do not show correct
value – 1) PLC FATEK must be in the PLC.
Run
mode. Use WinProladder to run
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;$”) because
CMGSM reads the configuration till the first “$” character.
