FnIO S-Series MODBUS Programmable I/O NA-9379 A.2 MODBUS Transmission Mode Two different serial transmission modes are defined: The RTU mode and the ASCII mode. It defines the bit contents of message fields transmitted serially on the line. It determines how information is packed into the message fields and decoded. A.2.1.
PAGE 60
MODBUS Programmable I/O NA-9379 FnIO S-Series A.3.1. 1 (0x01) Read Coils This function code is used to read from 1 to 2000 contiguous status of coils in a remote device. The Request PDU specifies the starting address, i.e. the address of the first coil specified, and the number of coils. In the PDU Coils are addressed starting at zero. Therefore coils numbered 1-16 are addressed as 0-15. The coils in the response message are packed as one coil per bit of the data field.
PAGE 61
MODBUS Programmable I/O NA-9379 FnIO S-Series A.3.2. 2 (0x02) Read Discrete Inputs This function code is used to read from 1 to 2000 contiguous status of discrete inputs in a remote device. The Request PDU specifies the starting address, i.e. the address of the first input specified, and the number of inputs. In the PDU Discrete Inputs are addressed starting at zero. Therefore Discrete inputs numbered 1-16 are addressed as 0-15.
PAGE 62
MODBUS Programmable I/O NA-9379 FnIO S-Series A.3.3. 3 (0x03) Read Holding Registers This function code is used to read the contents of a contiguous block of holding registers in a remote device. The Request PDU specifies the starting register address and the number of registers. The register data in the response message are packed as two bytes per register, with the binary contents right justified within each byte.
PAGE 63
MODBUS Programmable I/O NA-9379 FnIO S-Series A.3.4. 4 (0x04) Read Input Registers This function code is used to read from 1 to approx. 125 contiguous input registers in a remote device. The Request PDU specifies the starting register address and the number of registers. The register data in the response message are packed as two bytes per register, with the binary contents right justified within each byte.
PAGE 64
MODBUS Programmable I/O NA-9379 FnIO S-Series A.3.5. 5 (0x05) Write Single Coil This function code is used to write a single output to either ON or OFF in a remote device. The requested ON/OFF state is specified by a constant in the request data field. A value of FF 00 hex requests the output to be ON. A value of 00 00 requests it to be OFF. All other values are illegal and will not affect the output.
PAGE 65
MODBUS Programmable I/O NA-9379 FnIO S-Series A.3.6. 6 (0x06) Write Single Register This function code is used to write a single holding register in a remote device. Therefore register numbered 1 is addressed as 0. The normal response is an echo of the request, returned after the register contents have been written.
PAGE 66
MODBUS Programmable I/O NA-9379 FnIO S-Series A.3.7. 8 (0x08) Diagnostics MODBUS function code 08 provides a series of tests for checking the communication system between a client (Master) device and a server (Slave), or for checking various internal error conditions within a server. The function uses a two–byte sub-function code field in the query to define the type of test to be performed. The server echoes both the function code and sub-function code in a normal response.
PAGE 67
MODBUS Programmable I/O NA-9379 FnIO S-Series  Sub-function 0x0000(0) Return Query Data The data passed in the request data field is to be returned (looped back) in the response. The entire response message should be identical to the request.
PAGE 68
MODBUS Programmable I/O NA-9379 FnIO S-Series  Sub-function 0x000F(15) Return Slave No Response Count The response data field returns the quantity of messages addressed to the remote device for which it has returned no response (neither a normal response nor an exception response), since its last restart, clear counters operation, or power–up.
PAGE 69
MODBUS Programmable I/O NA-9379 FnIO S-Series A.3.8. 15 (0x0F) Write Multiple Coils This function code is used to force each coil in a sequence of coils to either ON or OFF in a remote device. The Request PDU specifies the coil references to be forced. Coils are addressed starting at zero. A logical '1' in a bit position of the field requests the corresponding output to be ON. A logical '0' requests it to be OFF.
PAGE 70
MODBUS Programmable I/O NA-9379 FnIO S-Series A.3.9. 16 (0x10) Write Multiple Registers This function code is used to write a block of contiguous registers (1 to approx. 120 registers) in a remote device. The requested written values are specified in the request data field. Data is packed as two bytes per register. The normal response returns the function code, starting address, and quantity of registers written.
PAGE 71
MODBUS Programmable I/O NA-9379 FnIO S-Series A.3.10. 23 (0x17) Read/Write Multiple Registers This function code performs a combination of one read operation and one write operation in a single MODBUS transaction. The write operation is performed before the read. The request specifies the starting address and number of holding registers to be read as well as the starting address, number of holding registers, and the data to be written.

A.4 MODBUS Programmable I/O NA-9379 FnIO S-Series MODBUS Special Register Map The special register map can be accessed by function code 3, 4, 6 and 16. Also the special register map must be accessed by read/write of every each address (one address). A.4.1.

MODBUS Programmable I/O NA-9379 FnIO S-Series A.4.3. Adapter Watchdog Time, other Time Special Register (0x1020, 4128) A watchdog timer can be configured for timeout periods up to 65535(1unit=100msec). The Watchdog timer will timeout (timer decreased, reached 0) if MODBUS operation to the slave node does not occur over the configured watchdog value, then the slave adapter forces that slot output value is automatically set to user-configured fault actions and values.

FnIO S-Series MODBUS Programmable I/O NA-9379 A.5 Example A.5.1. Example of Input Process Image(Input Register) Map Input image data depends on slot position and expansion slot data type. Input process image data is only ordered by expansion slot position when input image mode is uncompressed (mode 0, 2). But, when input image mode is compressed (mode 1, 3), input process image data is ordered by expansion slot position and slot data type.
