Page 32: Computer/Local Transfer
3. SETTING FOR COMMUNICATION 3.2.3 Computer/Local transfer SR Mini HG SYSTEM has two communication modes: local mode and computer mode. The host computer can perform only monitoring (polling) in local mode. In computer mode, it can perform monitoring and setting (selecting).
Page 33: Communication Protocol
RKC communication uses the polling/selecting method to establish a data link. The basic procedure is followed ANSI X3.28-1976 subcategories 2.5 and B1 basic mode data transmission control procedure (Fast selecting is the selecting method used in SR Mini HG SYSTEM). • The polling/selecting procedures are a centralized control method where the host computer controls the entire process.
Page 34 4. COMMUNICATION PROTOCOL The above procedure is for SR Mini HG SYSTEM transmission control. However, the operation panel (OPC *) can correspond not only to SR Mini HG SYSTEM communication but also to programmable controller (PC) communication (option). The PC communication control procedure differs from the SR Mini HG SYSTEM communication control procedure and also from the procedure for communication between each programmable controller manufactured by the respective company.
Page 35: Polling Procedure
4. COMMUNICATION PROTOCOL 4.1.1 Polling procedure (1) Data link initialize In order to initialize the data link before sending the polling sequence, send [EOT] from the host computer. (2) Polling sequence send Send the polling sequence from the host computer in the following format. Address Identifier 1.
Page 36 4. COMMUNICATION PROTOCOL (3) Data send from this device This device sends data in the following format if it received the polling sequence correctly. Identifier Data Identifier Data If the length of send data (from [STX] to [BCC]) exceeds 128 bytes, it is divided into blocks by [ETB].
Page 37 4. COMMUNICATION PROTOCOL 4. ETB Transmission control character indicating the end of the block. 5. ETX Transmission control character indicating the end of the text. 6. BCC Block check character for error-detection, uses horizontal parity. [BCC] is calculated by horizontal parity (even number).
Page 38 4. COMMUNICATION PROTOCOL (6) ACK (Acknowledge) If the host computer receives data sent correctly from this device, send ACK. The device then sends data next to the identifier just sent . In order to stop sending data from this device, send EOT from the host computer to terminate the data link.

Page 40: Selecting
ID: Identifier The above procedure is for SR Mini HG SYSTEM transmission control. However, the operation panel (OPC *) can correspond not only to SR Mini HG SYSTEM communication but also to programmable controller (PC) communication (option). The PC communication control procedure differs from the SR Mini HG SYSTEM communication control procedure and also from the procedure for communication between each programmable controller manufactured by the respective company.
Page 41: Selecting Procedure
4. COMMUNICATION PROTOCOL 4.2.1 Selecting procedure (1) Data link initialize Send EOT from the host computer to initialize the data link before sending the selecting sequence. (2) Selecting sequence send Send the selecting address for the selecting sequence from the host computer. Address This is the unit address of this device to be selected.
Page 42 4. COMMUNICATION PROTOCOL (4) ACK (Acknowledge response) If this device receives data sent correctly from the host computer, it sends ACK to the host computer. Then, if there is data to be sent next from the host computer, send it to the device. After the data has been sent, send EOT to terminate the data link.

Page 97 5. COMMUNICATION IDENTIFIERS  Control loop break alarm (LBA) function The LBA function detects the abnormality in the control loop such as the break of load (heater), the abnormality of external operating unit (magnet relay etc.), the break of input (sensors), etc. When the output reaches 100 % or 0 % (or output limiter low limit) the LBA function starts to monitor periodically the change of measured value (PV) at previously set time and detects the break of heater and input.
