12 Connection and time scheduling with RS 485 operation In the RS 485 operation and depending on the number of leads, a time scheduling has to be carried out by means of load resistances at the two most remote bus terminals. Figure 4 below shows the wiring example for MDH 5xx in the 4-wire operation and figure 5 the 2-wire operation. Figure 4 Figure 5 Time scheduling in RS wire operation is not possible at the moment. Page 12 of 66

13 5.3 General description for devices with GSM connection This chapter describes the handling of devices with GSM connection. Data call has to be activated with the SIM card used. For data call, a separate telephone number is attributed by the network providers. The SIM card is only to be inserted or taken out if no voltage is applied to the device PIN Number If the SIM card is PIN protected, the PIN number has to be stored in the device. The PIN number is four-digit. Depending on the mode of operation and the type of device, there are different possibilities. The PIN number should be transferred to the device before inserting the SIM card. If the PIN number of the SIM card and the PIN number stored in the device are not the same, the SIM card is locked after three attempts (per reset or voltage reset 1 attempt). Now, the SIM card is PUK protected. You will normally get the PUK code together with your SIM card. The SIM card has then to be inserted into a mobile phone and the PUK code has to be entered Switch position 0 (Modem operation) In switch position 0, the devices are working in the standard modem operation. Here, the PIN number has to be transferred via the AT:20=PIN-Number command (Example: AT:20=1234) Switch position 1,2 (Control driver operation) In this mode, the PIN number entered in the Modcom software is transferred to the device by means of the initialisation process Switch position 4, 8, 9, A (MDH 513/543/553 TS-Modem operation) In this mode, the MDH 513/543 works as a TS-Modem adapter. Parameterisation of the device can be carried out via the Siemens Teleservice software. The PIN number has to be transferred via the initialisation command using the AT+CPIN= PIN-Number command. The PIN number has to be in quotation marks and be separated from the remaining commands by a semicolon Insertion of SIM card 45 The slide-in unit for the SIM card is located at the lower side of the housing. By pressing the embedded yellow button next to the card reader, the slide-in unit is forced out and can be taken out. The SIM card has to be inserted into the slide-in unit. The slide-in unit can then be reinserted into the card reader again. 120 SIM Ant. Page 13 of 66

14 5.3.3 Diagnosis The status of the GSM module can be identified using the flash code of the red error LED. 5x flash Error at SIM card -SIM card not plugged -SIM card is defective -PIN number not correct 6x flash No GSM network available or not yet booked in -PIN or PUK number is missing - No receive (check antenna) - Network not available in this area With a new start, the initialisation and booking-in processes into the GSM network can last for about 60 seconds. During this time, the flash code for a non-available GSM network is displayed (6-times flashing of the error LED). In the Modcom software, the GSM status of devices connected to a PC can be permanently called. With remote devices, the last status can be inquired after establishing the modem connection. If the GSM device is operated as standard modem, the GSM status can be inquired using the AT commands. Please see chapter for the required commands. Page 14 of 66

15 5.4 Ethernet (MDH 520, 522) Configuration of the IP-Address Configuration of the IP-address has to be made via a network connection. To do this, the Ethernet module and the configuration PC have to be linked to each other via a network or a crossed network cable (Cross Over Cable). Enter the command "telnet (IP-address) 9999" in the MS-DOS input window or at the Windows start menu Execute (the preset IP-address is: ) and confirm by return. Now, the Telnet window opens. Press the return key within 5 seconds. Then, the following window is displayed: Configuration of the Ethernet interface is made in this window. Enter "0" (zero) (server configuration) and confirm. Page 15 of 66

16 The following settings have to be made: Setting of IP-address (e.g ) Setting of Gateway IP-address: enter "N" Change telnet config password: enter "N" Then save the settings by entering "9" and end Telnet. When using the Ethernet interface in connection with the Modcom 32Bit, please see the description "Ethernet connection mbpoint" for further information on how to handle the device. Page 16 of 66

17 5.4.2 Interface X5 10Base-T This interface works with 10 MBit/s and is used for connection of devices with an Ethernet interface or the corresponding networks. 45 X3 SW3 LED6 LED5 LED3 LED1 LED2 LED4 SW1 9 8 X SW2 1 8 RJ45 Figure 6 Pin Description RJ 45 10Base-T 1 Tx+ 2 Tx- 3 Rx+ 4 n.c. 5 n.c. 6 Rx- 7 n.c. 8 n.c. n.c.= not connected Description X5 Network LED s LED Description 7 Lights up when network connection has been identified, Flashes when connection is active 8 Diagnosis (see LED 9) 9 LED 9 lights up and (LED8 flashes) 1x EPROM check sum error 2x RAM Error 3x Network controller error 4x EEPROM check sum error 5x Network address already allocated 6x Software and Hardware not compatible LED9 flashes and (LED8 lights up) 4x incorrect network connection 5x no DHCP log data communication 10 Lights up when network interface is active Page 17 of 66

18 5.5 Ethernet 2 (MDH 530, 532, 533, 550, 552, 553) Configuration of the Ethernet interface (X5) can be made via a network connection. To do this, the MDH53x has to be linked via the Ethernet interface and the configuration PC has to be linked via a network or a crossed network cable (Cross Over cable) Configuration of the IP-addresses Enter the command "telnet (IP-address) 10000" in the MS-DOS input window or at the Windows start menu Execute (the preset IP-address is: ). In the log-in menu, the standard access data login: system and the password: mbconnectline have to be entered. The inputs have to be confirmed by return. Page 18 of 66

19 Selection of the submenus is displayed in the main menu. By entering the respective digit before the menu items, access to the desired submenu is possible. Submenu IP Parameters allows to see and change the individual parameters. If the IP-address of the device has to be changed for example, 1 has to be entered. The new IP-address can then be entered. The IP-address, the PPP Client IP-address as well as the PPP Server IP-address have to be in the same address area. It would be preferable to allocate the addresses in block (e.g.150, 151, 152) in order to avoid confusion with other subscribers in the network connected. Page 19 of 66

20 5.5.2 Configuration of access data The access data of the Ethernet interface of the MDH 53x can be modified in the user/password menu. You will reach the desired menu by entering the respective digit. Changing of the password requires entering the existing password before. The password will be mbconnectline when the device is delivered.. After quitting the configuration menu using digit 9 (Quit), the settings are only taken over after new start of the device. New start is triggered by pressing the reset button or by applying supply voltage to the MDH53x again. Page 20 of 66 The configuration menu can also be called via an existing RDT-Online connection and the setting can be modified. Here, attention has to be paid to the fact that the MDH53x has to be started again Configuration of routing table If the MDH 53x, 55x is to be selected via a router, the following setting has to be entered in the routing menu.

21 In the submenu Routing, the route into another network has to be activated via the Routing active menu. The route for the remote network has to be entered in the Host IP-Address menu. The Subnet Mask (Standard ) of the remote network has also to be set. The Gateway setting needs to have the same IP-address as the PPP Server IP-Address Example for allocation of IP-addresses Page 21 of 66

Decision with which interface of the MDH5xx the PC is to be connected (COM1 or MPI /Profibus) is made via MODCOM. Page 29 of 66

30 Advantages: no Teleservice software required can also be used with standard modems in connection with MDS400 Selection can be made between two different drivers. The MPI_M5.stc driver supports the log of Simatic Step 7 up to version 5.1. The driver can, however, also be used for more recent versions of the Simatic Step 7. The MPI_M5H.stc driver supports the log of Simatic Step 7 from version 5.1 This driver is available from VRH Communication with this driver is about 25% faster. Please see chapter PC-Adapter Operation for the settings in the Simatic Manager Settings in MODCOM In the MODCOM software, the MPI_M5.stc driver is automatically selected at interface 2 and can be changed to the MPI_M5H.stc driver, if required. These drivers are automatically installed with MODCOM and do not have to be purchased. Depending on the kind of log of the application software, standard or fast have to be selected. Normally, the setting fast is to be preferred as a higher data throughput is supported here. Depending on the MPI/Profibus baud rate of the network connected, it has to be indicated how the MPI/Profibus interface of the MDH 51x, 54x, 55x is to be set after establishing the connection. Switch to interface 2 (MPI/Profibus) in the settings menu prior to selection. Page 30 of 66

31 5.8.2 PC-Adapter operation In these modes of operation, the device is exclusively used as a PC-Adapter. MODCOM or modem operation is NOT possible! Please see the table above for the respective switch position required. Make the following settings in your Simatic Manager: Select the PC Adapter (MPI) (with access to an MPI device or network) or the PC Adapter (Profibus) (with access to a Profibus device or network) as approach to the control. Page 31 of 66

32 Settings PG/PC interface local connection Set in the field Connection to: the COM interface to which the base station or, with function as a PC Adapter, the MDH5xx is connected to. Transmission speed has to be firmly set to Page 32 of 66

33 5.8.3 TS-Modem operation In this mode of operation, the device is used as a TS-Modem adapter. This means that a TS adapter and a modem are combined into one housing. MODCOM operation is NOT possible! Functionality of the Siemens TS adapter of version V5.0 is supported from firmware version VRH of the MDH 5xx. This includes call back as well as password protection. Make the following settings in your Simatic Manager: Select the TS adapter as approach to the control Page 33 of 66

34 Settings TS-Adapter local connection You can use the TS adapter as direct connection or as modem connection. Set the COM interface to which the MDH51x, 54x, 55x is connected in the field direct connection to:. The transmission speed has to be firmly set to In order to be able to carry out the adapter parameterisation in the Teleservice Software (direct!y), direct connection has to be activated. The following settings in the Siemens Teleservice software are accepted by the TS modem: Initialisation: Only change the parameter 1 (number of calls until the modem takes the call) of the ATS0= sequence. Further initialisation sequences are registered in the firmware of the devices. For adaptations to the country or the like, please see chapter Modem Operation for the commands. Page 34 of 66

35 Additional commands may disturb operation and may lead to undefined conditions of the device. If you would like to use any other command than our description, please contact the Support Centre. Indication for ISDN devices: The AT#Z=n command defines the MSN (multiple subscriber number) AT#Z=n sets MSN to the value n Indications for GSM devices: The AT+CPIN PIN-Nummer command determines the PIN number. The PIN number has to be in quotation marks and be separated from the remaining commands by a semicolon. Deselection: This parameter is not used nor taken into account. Transmission speed, data bits, parity, stop bits: This parameter is firmly set to in the firmware. Page 35 of 66

36 With devices MDH 510/512/513, an MPI connection with a maximum of 187,5 kbits is possible only. In the access protection menu, password protection as well as the call back number can be registered. For further information, please see the help of the Teleservice Software. Page 36 of 66

37 6 Modes of operation The different modes of operation are selected via the rotary switch SW2. The new mode of operation is taken over by pressing the reset key SW3. An exact description of the possible deviations from the mode of operation selection can be seen in the individual chapters. 6.1 Modem operation (switch position 0) In this mode, the device works as a standard modem and configuration to its proper settings can be made here. The MDH5xx has a presetting for the modem or the ISDN TA which generally do not have to be modified. If required, another configuration can be made, however, via the enlarged commands AT:993 and AT:994 with the respective modem(at) commands. The serial interface RS232/485 is also adjusted via the enlarged commands AT:01, AT:02, AT:03 and AT: Standard Commands Difference is basically made between 2 modes of operation: Command phase: in this mode of operation, interpretation of the AT commands sent is made via the modem and it also executes the corresponding command, ONLINE-Phase: as soon as a telephone connection has been established between 2 modems, this mode of operation is active AT:00 Init-Sequence before starting the modem operation Command AT:00=<Start- Sequence> [CR] AT:00?[CR] Function The text mentioned here (<Start sequence>) is transferred to the modem part every time before starting the modem operation. Enter the AT:00=ATS0=1 command for an automatic call acceptance for instance. The text is saved non volatile in the devices. You will get the saved start sequence back. Page 37 of 66

38 AT:01 Configuration of serial interface COM1 during command phase Command AT:01=<Typ>,<Baud rate>, <Format>, <Handshake>[CR] AT:01? [CR] Function Setting of the serial interface is activated every time after starting the modem operation. Example: Factory setting: 1,1,0,0; means that the modem has to be triggered as RS232 with an automatic baud rate identification, 8 data bits, no parity,1 stop bit. If another setting is chosen, communication of the device is only possible with this setting. Take over after reset You will get the saved interface setting back. Syntaxe: AT:01=<Typ>,<Baud rate>,<format>,<handshake> <Typ> Meaning 1 RS232 2 RS485 2 Line operation 3 RS485 4 Line operation <Handshake> Meaning 0 No handshake 1 XON/XOFF 2 RTS/CTS Table 1 Table 2 <Baud rate> Meaning 1 Automatic bit/s bit/s bit/s bit/s bit/s bit/s bit/s bit/s bit/s bit/s bit/s bit/s bit/s bit/s bit/s Table 3 <Format> Meaning 0 8 data bits, no parity, 1 stop bit 1 8 data bits, odd parity, 1 stop bit 2 8 data bits, even parity, 1 stop bit 3 8 data bits, no parity, 2 stop bits 4 8 data bits, odd parity, 2 stop bits 5 8 data bits, even parity, 2 stop bits 6 7 data bits, no parity, 1 stop bit 7 7 data bits, odd parity, 1 stop bit 8 7 data bits, even parity, 1 stop bit 9 7 data bits, no parity, 2 stop bits 10 7 data bits, odd parity, 2 stop bits 11 7 data bits, even parity, 2 stop bits Table 4 Page 38 of 66

39 AT:02 Configuration of serial interface COM2 during command phase Command AT:02=<Type>,<Baud rate>, <Format>, <Handshake>[CR] AT:02? [CR] Function Setting of the serial interface is activated every time after starting the modem operation. Example: Factory setting: 1,1,0,0; means that the modem has to be triggered as RS232 with an automatic baud rate identification, 8 data bits, no parity,1 stop bit. If another setting is chosen, communication of the device is only possible with this setting. You will get the saved interface setting back. Parameters such as <Type>, <Baud rate>, etc. are identical with command AT: AT:03 Configuration of serial interface COM1 during ONLINE phase Command AT:03=<Type>,<Baud rate>, <Format>, <Handshake>[CR] AT:03? [CR] Function Setting of the serial interface is activated every time after starting the modem operation. Example: Factory setting: 1,1,0,0; means that the modem is triggered as RS232 when the data are taken over by AT:01. This means that the parameters are taken over by AT:01 when the baud rate is set to automatic (type, baud rate, handshake, data format). You will get the saved interface setting back. Parameters such as <Type>, <Baud rate>, etc. are identical with command AT: AT:04 Configuration of serial interface COM2 during ONLINE phase Command AT:04=<Type>,<Baud rate>, <Format>, <Handshake>[CR] AT:04? [CR] Function Setting of the serial interface is activated every time after starting the modem operation. Example: Factory setting: 1,1,0,0; means that the modem is triggered as RS232 when the data are taken over by AT:02. This means that the parameters are taken over by AT:04 when the baud rate is set to automatic (type, baud rate, handshake, data format). You will get the saved interface setting back. Parameters such as <Type>, <Baud rate>, etc. are identical with command AT:01 Page 39 of 66

40 AT:05 Setting of mode of operation in the ONLINE phase Command AT:05=<Mode of operation>[cr] AT:05? [CR] Function This command decides on the fact with which interface (COM1 or COM2) the integrated modem communicates in the Online phase. This parameter is only relevant with devices with more than one interface (e.g. MDH504). Please see the table below for the possible modes of operation. You will get the saved setting back. <Mode of operation> Meaning 0 In the Online phase, the modem interface is connected to the default interface (also see AT:07) 1 Waiting for an input. 2 The modem interface is connected to COM1. 3 The modem interface is connected to COM2, MPI or the Ethernet interface. Mode of operation 1: After a CONNECT has been made, the MDH5xx sends COM?: to the remote station. the remote station has to respond with a valid interface number. e.g. 2 (without CR). The MDH5xx then gives an OK or an ERROR AT:06 Activate password protection Command AT:06=<Password protection>[cr] Syntaxe AT:06? [CR] Function This command decides whether a password has to be sent from the remote station after communication has been established. The password sent always needs to have a D or an R as first letter. This decides on the fact whether the MDH5xx calls back or not. 0 = deactivated; 1 = activated You will get the saved setting back. e.g: Process without call back: MDH5xx Remote station Password: > < Dmbconnectline[CR] OK or ERROR > Process with call back: MDH5xx Remote station Password: > < Rmbconnectline[CR] Call back number: > < [CR] Call back number: OK >? (Y/N) < Y[CR] or N[CR] MDH5xx disconnects and calls back Page 40 of 66

41 AT:07 Setting of default interface in command phase Command AT:07=<Number>[CR] AT:07? [CR] Function This command decides on the fact with which interface (COM1 or COM2) the integrated modem communicates in the command phase. This parameter is only relevant with devices with more than one serial interface (e.g. MDH504, MDH 506). You will get the saved setting back. <Number> Meaning 1 COM 1 2 COM AT:20 Setting of PIN number Command Function AT:20=<PIN- Number>[CR] This command sets the PIN number e.g. AT:20=1234 AT:20? [CR] You will get the saved setting back AT:990 Inquiry of type of device Command AT:990? [CR] Function This command allows you to inquire the type of device. - E.g.

[CR] Function This command allows you to inquire the ID of the device. - E.g This ID is only required for support purposes AT:992 Setting of password Command AT:992=<Password> [CR] AT:992? [CR] Function Use this command to enter the password. ATTENTION: This password is identical to the one in control driver operation You will get the saved setting back. E.g. AT:992=mbconnectline[CR] AT:993 Setting of the general init-sequence Command AT:993=<Init-sequence>[CR] AT:993? [CR] Function The text mentioned here (<Init -sequence>) is transferred to the modem part every time the device is booted. This sequence is only to be modified on consultation with the Support Centre of MB Connect Line GmbH. Factory setting depends on the modem Analog: AT&F^M ISDN: ~~~~~~~~~AT&F^M GSM: AT&F^M You will get the saved setting back. Page 41 of 66

42 AT:994 Setting of the general config-sequence Command AT:994=<Configsequence>[CR] AT:994? [CR] Function The text mentioned here (<Config-sequence>) is transferred to the modem part every time the device is booted. This sequence is only to be modified on consultation with the Support Centre of MB Connect Line GmbH.

46 6.1.2 General indications to AT commands The AT-Standard is a line-oriented command language. Every command basically consists of three elements: Prefix, Command and Confirmation. The Prefix always consists of the characters AT, the only exception is command A/. The command is composed of individual characters which are described as follows. The command consists of an abbreviation and the values belonging to it, if any. The Confirmation <CR> (Carriage return, Return, Enter) Use of small initial letters and capital letters is accepted. Several commands can be combined to one command line. The commands are acknowledged using OK or ERROR. A command in process is interrupted by every incoming signal. This is why the next command has to wait until being acknowledged as otherwise the current command will be deleted. The supported commands are described in the following. Standard values are written in bold letters. If necessary, additional descriptions on further commands can be obtained by MB Connect Line GmbH Commands of modem A/ The modem repeats the command sequence last entered. Please pay special attention to the fact that the prefix AT is not to be entered and command A/ is not to be terminated by >CR<. ATA ATB When the automatic call acceptance is deactivated (register ATS0=0), this command allows to accept an incoming call. Select communication standard ATB0 CCITT Modulation ATB1 Bell Modulation AT\B AT&C Handling of break signal AT\Bn Send break signal to remote station n= 0-9 in 100 ms units (standard AT\B3) Only possible with non error-corrected connection Setting of DTR signal AT&D DTR signal is ignored AT&D2 DTR signal is evaluated. Inactive signal disconnects connection. The incoming call is only accepted with the DTR signal active. AT%C Setting of data compression AT%C0 no data compression AT%C1 no data compression Page 46 of 66

47 ATD Examples Initialisation of selective process The modem responds and dials as per the dial string transferred by the ATD command. After dialling, the modem tries to establish a connection. The following characters may be entered as dial parameters: 0 bis 9 dial digits *, #, A- D with voice frequency dialling L repeat last call of the number last dialled P dial-up with pulse dialling method (not for EU) T W dial-up with voice frequency dialling method wait for dialling tone. The modem waits for a dialling tone before it starts dialling. If no dialling tone is identified within the time determined in register S6, the modem disconnects the set and displays an error message., Dialling pause (definition in register S8) ATD dials the telephone number ATDT dials the telephone number in the pulse dialling method ATDP dials the telephone number in the voice frequency dialling method ATX3DT dials the telephone number in the voice frequency dialling method and does not wait for a dialling tone (see command ATX3) AT&D Setting of DTR signal AT&D0 AT&D1 AT&D2 AT&D3 The DTR signal is ignored. Allows for operation at PCs which do not operate the DTR signal. With DTR ON/OFF change, an existing connection is interrupted. With DTR ON/OFF change, the existing connection is interrupted. Automatic response is not possible. With DTR ON/OFF change, a soft reset ia triggered (see ATZ). A previous AT&Y command decides whether presettings 1 or 2 are loaded. ATE Sets the local response in the command mode. ATE0 no local response ATE1 local response switched on during command input AT&F Loading of factory setting AT+GCI See chapter 6 AT&F0 Loading of factory setting 0 AT&F1 Loading of factory setting 1 ATH Terminate connection After putting in the escape sequence ( +++ ), the connection can be disconnected using the ATH command and the modem disconnects.

The MODCOM 32Bit software is required for transferring the new firmware. The current firmware can be obtained in the download area of our Websites. Insert the MDX500.HEX file in the DAT directory of the Modcom32Bit file. (e.g.: C:\Programme\MB Connect Line GmbH\MODCOM32Bit\DAT) For transferring the firmware, the device has to be started in positions 1 or 2. If the update process is interrupted via the telephone line with a device having a GSM connection, it is not allowed to separate the device from the supply voltage or to press the reset key as otherwise the PIN number will no longer be transferred to the GSM module. The MODCOM 32Bit shows in the info line which firmware version is available to Modcom. The info line also indicates the version status the triggered device has loaded. Page 59 of 66

60 The update process can be initiated via the Menu Options, -> Operating system ->, Update for Series,- > 500 Base station/system station. If a device directly connected to the PC is to be updated, Base station has to be selected. If the firmware is to be updated with a remote device, System station has to be selected. In this case, using the telephone number of the active station, a Modem connection is established and the firmware is transferred. The active boot loader or the listening watch for the firmware update is displayed at the mbpoint by simultaneous flashing of the LEDs ONLINE, READY and ERROR. POWER Figure 11 READY ERROR RxD TxD ONLINE Modcom 32Bit displays the following messages. Figure 12 Figure 13 Page 60 of 66
