Page 5: Introduction
INTRODUCTION Your new modem is one of the most technologically advanced available. It combines high-speed data, fax, voice and ASVD (Automatic Simultaneous Voice and Data) functions in a single unit. The modem has been designed to complement the Mitsubishi FX and A ranges of PLC’s, and provides a number of unique telemetry features for handling data transfers between PLC’s. -
Page 6: Section 1 - Modem Standards And Compatibility
The modem has been designed to operate in all European Countries and complies with standard TBR21. 1.2 What you should have in your package A2S-MODEM One A2S-MODEM module One PC Utilities Software Diskette * One Telephone Cable (BT – UK only) One 24 Volt dc connector... -
Page 7: Section 2 - Getting Started
Secure the module with the retained mounting screw at the top. NOTE: Installing the A2S-MODEM on the backplane does not connect to the Bus or take power or occupy I/O addresses. To avoid loosing any I/O addresses, assign “S0”, under Parameters in the PLC software, for that slot. -

Page 10: Wiring
2.2.6 Wiring 24V dc Supply A2S and DIN Versions Wire 24 dc from a suitable supply, usually from terminals on a nearby module to the miniature screw terminal plug provided. Check the specification for the 24V supply before making connection. However, reversing the polarity of the dc will cause no harm. -
Page 11: Section 3 - Using The Enhanced Functions
Section 3 – Using the Enhanced Functions In order to configure your modem and use its enhanced functions it must be connected to the serial port of a PC running terminal software such as Terminal, HMI Tools \Modem, Hyper-Terminal or ProComm Plus. This section describes how this is done. 3.1 Setting the Modem with Terminal Software The modem is pre-set to communicate at 9600 Baud with 8 data bits, 1 stop bit and No parity. -
Page 12: Automatic Simultaneous Voice And Data
3.2 Automatic Simultaneous Voice and Data To use the ASVD function, simply plug a suitable handset or headset into the front panel socket marked with a handset symbol. Voice and data communication will be made automatically during the period that the modem is connected. 3.2.1 Using Simultaneous Voice and Data with Other Modems Not all modems available support simultaneous voice and data functions. -
Page 13: Online Maintenance Using Mitsubishi Plc Programming Software
3.3 Online Maintenance Using Mitsubishi PLC Programming Software One of the most commonly used features of the modem is to contact a remote PLC and then use programming software to interrogate operation. To do this requires a two-stage operation. Modem- A2S DATA RS232 VOIC E... -
Page 14: Communicating With Mitsubishi Plc's
3.3.3 Communicating with Mitsubishi PLC’s Using the A2S/DIN/DESK Modems you will be able to transfer data between a PC/Laptop and a PLC, seamlessly without making any changes to the default settings in the HMI or Programming software. The modem can be connected directly to the PLC via a suitable RS-232 interface or through an HMI port in the “Transparent”... -
Page 15: Transferring Files From/To The Hmi
Secondly, load the HMI programming software and adjust the speed ‘Settings’ to 2400 baud in the ‘Transfer \ Project’ window before starting the transfer. NOTE: After each successful transfer the call must be terminated and redialled at 9600 baud before normal transparent mode to the PLC can be resumed. CAUTIONARY NOTE: At the time of writing. -

Page 17: Security
3.4 Security Your modem has the powerful facility of a two level access code (password) facility we call “User” and “Administrator” levels. The codes will both protect your system from unauthorised connection/communication and allow the on-line configuration of the remote modem’s parameters. Once set, anyone dialling in must enter the correct User access code before data will be allowed to pass through to your system. -
Page 18: Installing The Access Codes
3.4.2 Installing the Access Codes To install or change an access code it will be necessary to connect a PC directly to the modem via the PC serial port and the RS232 data connector. Use the MODEM-PC9- CAB or suitable lead and run your terminal software. Installing for the first time The factory default setting is no user code set. -
Page 19: Dial On Demand
3.5 Dial On Demand The dial on demand facility enables an FX or AnS PLC to command the modem to dial pre-stored telephone numbers and automatically exchange data with a remote site. IMPORTANT NOTE: The facilities described in sections 3.5 and 3.6 will not operate from an An(S)/QAn(S) PLC when connected via an HMI. -
Page 20: Example 3-4 Command Block Address Setting
2) Locating the command registers The command registers may be located in any valid D-type register within the PLC. A contiguous block of 7 registers is required. The modem will need to know the start address of this block and this is done with the command: AT%ADR = xxxxxx Where xxxxxx is the address from 1 to 6 digits. -
Page 21: Contents Of The Command Block
3.5.3 Contents of the command block The contents of the command block within the PLC are shown in the following figures. For a sample program that uses the dial on demand facility see section 10 at the end of this manual. COMMAND BLOCK D(x) Status register... - Page 22 Dial Request Bit (bit 0) In order to trigger a dial on demand action, the PLC program needs only to set the Dial Request (RQ) bit in the first register of the command block. When the RQ bit is set the telephone and action data is retrieved by the modem in the same poll, so remember to set these values before the bit! Stopped Polling bit (bit 1) The Stopped Polling bit (STP) is set by the modem while it is performing a...
-
Page 23: Setting Telephone Numbers
3.5.5 Setting telephone numbers When dial on demand is required, the modem uses the first telephone number value from the command block to determine the number to dial. If this value is in the range of 1 to 9 a speed-dial number is selected. If the value is in the range A to D (hex) then the modem will read a block of registers from the PLC, then dial the returned value. -
Page 24: Setting Fixed Messages In The Modem
By either swapping the value of the address in the command block, or by swapping the value at the directory address before making a dial request; a huge directory of telephone numbers becomes available, limited only by the amount of free data registers within the PLC. 3.5.6 Setting fixed messages in the modem Fixed (text) messages are stored within the modem, so must be pre-set by connecting the modem to a PC terminal, and using the command:... -
Page 25: Wide Area Telemetry (Wat)
3.6 Wide Area Telemetry (WAT) One of the most exciting features of your modem is its ability is not just to automatically dial on demand, but also exchange information with another, remote PLC. We refer to this process as Wide Area Telemetry (WAT) as it gives you the possibility of setting up a wide area network of PLC’s. -
Page 26: Information In The Wat Header
3.6.2 Information in the WAT Header The instructions read by the modem from the WAT header are in the form shown in the two figures below. It is the responsibility of the PLC program to transfer the correct information into these registers before requesting the transaction. WAT REGISTERS D(y) Number of data words to... -
