2 Simple Application Controllers

1. Communication Capabilities

The α2 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.

Communication Capabilities 1

The 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

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 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 personnel or the appropriate staff thus reducing downtime for machines and the necessity for on site

personnel at each location. The 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.

I Bit input pin for GSM/SMS function block operation

1) Detects the high status of an input and subsequently sends the SMS message to the predefined user destination.

2) The SMS message will continue to send regardless of the input switching to a low state.

3) The incoming high input will be ignored: a) During a SMS message transmission b) During the waiting period.

4) Communication failure (e.g. busy line) will tell the SMS function block to retry on two further occasions in a period of two minutes.

5)On the third retry the output status will switch to ON and an error message generated through the word pin of the function block.

6) The user may experience incorrect validity period timings. Please check with your Service Provider.

7) If both the Mobile (SMSC1) and Gateway (SMSC2) numbers are entered the number for the SMS in conjunction with the destination chosen. The

destination being either to a mobile phone or an email address.

1) The output status will set ON: a) In succeeding in sending a SMS message b) In failing to send a SMS message after three retries.

2 controller will automatically choose the correct path

Description

Output

2) If more than one SMS function block exists on the program, a FIFO (First In First Out) sequence is performed. *1

3) The following items are available for other function blocks: a) SMS message sent/SMS failed to be sent after 3 attempts b) Current Status

Note: *1 If a number of SMS Function Blocks have been used in one program the user must take

care when calculating the message sending order. The first message to be sent depends on the first input signal turning ON. Thus, if other messages are waiting to be sent they are then placed in a waiting queue. However, since the waiting queue is scan dependant, if after one scan the controller has failed to send the first message due to a busy line, thus, the following message order is no longer dependant on input signals turning ON but is solely dependant on the Function Block order.

7. The Command String

The following chapter explains the structure of both types of dedicated protocol format for the

2 Series Controller. The 8-bit binary protocol is available in two different formats:

1 ) Format A 2 ) Format B

The Command String 7

The Dedicated Protocol is based on a PC or Peripheral device sending messages to the controller and in return receiving replies to those commands. The string of data that

accomplishes these tasks is called the Command String. The Command String can be used to check the communication line, read/write from/to internal bit/word data, perform remote Run/ Stop operation with the controller, and to edit Time Switch data. The data contained in the Command String varies with the type of action to be accomplished.

Two formats have been designed to carry the data - Format “A” for simple Communication line checks and Format “B” for the more involved data processing instructions. The information to construct and read Command Strings is explained in this chapter.

Communication between the computer and the interrupts. The Transmit/Receive process is completed after the last operation has been

completed in the Function block sequence order. Refer to the Communication Timing section for further information concerning response delay time.

Note: 1 ) Format B WRITE/(RUN/STOP) operation can produce an error code even though a

standard complete flag has been sent. If the Transmit message contains the correct syntax then a complete flag will be sent, however, if the reply data is corrupt then a NAK message will be generated.

2 ) The write message string is intended for BIT data accessing, therefore, only one byte has

been allocated to the Device Status setting. To write to WORD data, 2 bytes must be allocated to the Device setting. Thus, caution in setting the No. of communication bytes and the sum code check must be taken.

Read/Write operation for Format B follows a different structure to Format A. Format B uses a more complex string to access internal devices. However, the write operation contains the Device Status parameter used to indicate the ON/OFF state of the intended device.

Time Switch settings follow Format B protocol, however, the structure and content of the string differs from the standard READ/WRITE mode operation. Refer to section 7.6.5 for further detailed information concerning Time Switch settings for Format B. Format B READ Mode Format B WRITE mode (BIT)

The maximum number of BIT devices that can be read at any one time is restricted by the maximum number of communication bytes (250 bytes) contained in a single message. Each device is represented by the Device code, Device No, (LB) and Device No. (HB).

(Max No. of Comm. bytes - (Format No. + Stat No. + Command + No. of Devices)) / (Device code + Device No(LB) + Device No. (HB)) = (250 - 4) / 3 = 246 / 3 = 82

Therefore, the user can read 1 - 82 BIT devices at any one time.

2 ) READ Message - WORD data

The maximum number of WORD devices that can be read at any one time is restricted by the maximum number of communication bytes (250 bytes) contained in a single message. Each device is represented by the Device code, Device No, (LB) and Device No. (HB).

(Max No. of Comm. bytes - (Format No. + Stat No. + Command + No. of Devices)) / (Device code + Device No(LB) + Device No. (HB)) = (250 - 4) / 3 = 246 / 3 = 82

Therefore, the user can read 1 - 82 WORD devices at any one time.

2 Simple Application Controllers

3 ) WRITE Message - BIT data

The maximum number of BIT devices that can be written at any one time is restricted by the maximum number of communication bytes (250 bytes) contained in a single message. Each device is represented by the Device code, Device No, (LB), Device No. (HB) and Device Status (1byte).

(Max No. of Comm. bytes - (Format No. + Stat No. + Command + No. of Devices)) / (Device code + Device No(LB) + Device No. (HB) + Device Status) = (250 - 4) / 4 = 246 / 4 = 61

Therefore, the user can write 1 - 61 BIT devices at any one time.

4 ) WRITE Message - WORD data

The maximum number of WORD devices that can be written at any one time is restricted by the maximum number of communication bytes (250 bytes) contained in a single message. Each device is represented by the Device code, Device No, (LB), Device No. (HB), Device Status (LB) (1byte) and Device Status (HB) (1byte).

(Max No. of Comm. bytes - (Format No. + Stat No. + Command + No. of Devices)) / (Device code + Device No(LB) + Device No. (HB) + Device Status(LB) + Device Status(HB)) = (250 - 4) / 5 = 246 / 5 = 49

Therefore, the user can write 1 - 49 WORD devices at any one time.

5 ) Time Switch READ Message.

The READ operation of a Time Switch settings follows the identical structure to reading a Communication Word device in Format B. The maximum number of Time Switch devices that can be read at any one time is restricted by the maximum number of communication bytes (250 bytes) contained in the reply message.

(Max No. of Comm. bytes - (Format No. + Stat No. + Command + No. of Devices)) / (RTC0 + RTC1 + RTC2 + RTC3) = (250 - 4) / 4 = 246 / 4 = 61

Therefore, the user can read 1 - 61 Time Switch settings at any one time. Refer to section 7.6.5 for further infromation concerning Time Switch settings.

The Command String 7

6 ) Time Switch WRITE Message

The maximum number of Time Switch devices that can be read at any one time is restricted by the maximum number of communication bytes (250 bytes) contained in a single message. Each device is represented by the Device code, Device No, (LB), Device No. (HB), RTC+0, RtTC+1, RTC+2 and RTC+3.

(Max No. of Comm. bytes - (Format No. + Stat No. + Command + No. of Devices)) / (Device code + Device No(LB) + Device No. (HB) + RTC0 + RTC1 + RTC2 + RTC3) = (250 - 4) / 7 = 246 / 7 = 35

Therefore, the user can write 1 - 35 Time Switch settings devices at any one time. Refer to section 7.6.5 for further infromation concerning Time Switch settings.

A mixture of Time Switch, BIT and WORD data can be sent via one Transmit message.

7.3.8 Device Number

The Device Number is used in conjunction with the Device Code. Once the Device has specified what the internal device represents, then the Device Number is used to select the appropriate device from the range mentioned above. Each Device Number is comprised of 2 bytes: Lower byte (LB) Higher byte (HB) Example - The user wants to check the status of Input 11. Converting input 11 to a four digit Hexadecimal number 00 0B. The Higher Byte (HB) = 00. The Lower Byte (LB) = 0B. Thus, the user will enter the Device Code followed by 0B 00 to read/write data from/to Input 11.

7.3.9 Device Status

1 ) BIT Device - A single byte is allocated to the Device Status when used for both READ and

WRITE operations.
