2 Simple Application Controllers Communication Capabilities 1

1. Communication Capabilities The 2 Simple Application Controller has a wide range of communication capabilities that include remote programming, sending SMS messages to mobile telephones or e-mail accounts, and reading/writing data using a dedicated protocol. These powerful features bring a new era of information transfer possibilities to the simple application controllers.

The 2 can be used to monitor and control machines in remote stations and notify maintenance personnel in case of machine error or emergency situations. Remote monitoring through the AL-PCS/WIN-E software (version 2.00 onwards), hereafter referred to as VLS, can provide machine production and status updates as well as enable programming or parameter updates without the necessity of local access.

The Dedicated Protocol option gives the user the ability to transfer and monitor data from a peripheral device without the use of VLS software. Programmers familiar with C, C++, Visual Basic, or similar packages can write specialized communication programs.

Both standard and GSM modems can connect to the 2 controller.

The most powerful function is the ability to send SMS packets to e-mail accounts or mobile phones. The new functional block which strengthens the communication from external equipment was added to 2 Controller (version 2.20 or later). The new functional blocks is "Short Message Receiving(SMR) "and" Call Detect (CD)." "Short Message Receiving (SMR)" changes an output by the character string of a mail account. And "Call Detect (CD)" By GSM modem or an analog modem that supports"Calling Line Identification Presentation(CLIP)", an output is changed by call RING of a telephone. This functionality enables messages to be sent from remote locations to maintenance person- nel or the appropriate staff thus reducing downtime for machines and the necessity for on site personnel at each location. The 2 Series Controller can connect to a GSM modem or stan- dard modem to provide remote program upload/download, to monitor devices, set Function Block parameters, or change the I/O status. Program upload/download can be performed remotely by a PC that is using VLS software.

The procedure for Dedicated Protocol, which can remotely monitor or set parameters without using the VLS software, is discussed in Chapters 5 - 9.

Error messages can be prepared and placed on the 2 display to be sent as the SMS packet. Please refer to section 2.3 to view the available character set for SMS/GSM communication. The 2 Series Controllers communicates with a GSM or Standard modem from the connection port on the right side.

Note: The controller communicates to a modem via the left side port and cannot connect to a GSM modem.

2 Simple Application Controllers SMS/SMR/CD Functions and the Modem Setting 2

2. SMS/SMR/CD Functions and the Modem Setting SMS messages can be sent to mobile phones and e-mail accounts via a GSM modem if certain parameters in the 2 controller are correctly configured. The output of SMR changes, when the command text is exactly included in Short Message. The output of CD changes, when called from the modem that supports Calling Line Identifica- tion Presentation (CLIP). These parameters can be set quickly and easily in the VLS software or from the front panel keys. Refer to section 1.1 for the system configuration.

2.1 Set the parameters of the GSM modem from VLS software. The Visual Logic Software (VLS) provides the easiest method to set the parameters and download them to the controller. The communication method is the first setting necessary in the VLS software. When use a standard modem by CD Funcion Block, see section 3.3.

Open or start a new program and then choose Option on the menu bar. Click GSM and Serial Communication to open the dialog box necessary to begin parameterisation.

2.1.1 GSM & Serial Communication Dialog Box The GSM and Serial Communication Dialog Box is used to set the equipment and communication type for the controller. Refer to the AL-PCS/WIN-E Software Manual for further information concerning VLS. Click the GSM option to enable GSM telemetric functionality.

A) Not Use This default setting is for situations in which no communication will be used. The AT command is not activated. B) Modem This setting is used when a standard modem will be connected to the 2 for use in Remote Access. C) GSM This setting is used when a GSM modem will be connected either to send an SMS message or for Remote Access. D) Other This setting is used for Dedicated Protocol communication. E) Pin Code The GSM PIN (Personal Identification Numbers for use of GSM) F) Pin Code with the quotation mark GSM SIM PIN is sent to the modem in quotation marks (necessary for Sony Ericsson GSM modem) G) Remote Access Setting to allow GSM modems to have Remote Access. H) Data Format Settings for Com ports and message protocol. I) Initialize Modem AT Command used to initialize a modem. See section 2.1.2 for more details.

2.1.2 The Initialize Modem... Setting When the Initialize Modem... button is clicked, the Initialize Controller Modem dialog box is displayed. This box is used to enter the AT command for the modem and the Power On Delay time.

A) Initialize Command Enter the AT command for the modem. This setting will be automatically entered if one of the preconfigured modems is chosen, see section 2.1.3.

B) Power On Delay The Power On Delay will set the time in seconds that the 2 will wait on power-up before sending the Modem Initialization command. The delay can help to ensure that the modem is ready to receive the signal from the 2 in case there is a difference in the time necessary to power-up each item.

2.1.3 Pre-Configured GSM Modem Initialization Setting If using the Modem or GSM option, a preconfigured modem can be used. Choose the down arrow to view the modem options.

Choose one of the listed modems and the AT command will be automatically entered into the software parameter settings in Initialize Modem... The frame above shows a preconfigured setting for a GSM modem. The option for the GSM modems is listed below.
