1. COMMUNICATIONS SETUP

The Setup of the communications on the I500 or M2x3 is achieved using the QDSP configuration software. QDSP can communicate with the iSTAT products via RS232, RS485, USB and Ethernet. The option used will depend on which communication port is fitted to the product.

The QDSP software always uses Modbus protocol to communicate with the product.

1.1 Setup communications on the M2x3 and I500

The setup of the communication ports is done using the QDSP software and is detailed in a separate manual.

It is suggested that the communications channel for the product required by the application is initially set up using QDSP running on a PC. Then when that is working correctly the product can be connected to the required intelligent device.

1.2 Ethernet

When using the QDSP over Ethernet the set-up will depend on how the PC and the product are connected. The Communication interface must have a unique IP address in the Ethernet network. Two modes for assigning IP are available:

Fixed IP address: In most installations a fixed IP address is required. A system provider usually defines IP addresses. An IP address should be within a valid IP range, unique for your network and in the same Subnet mask as your PC.

DHCP: Automatic method of assigning IP addressed (DHCP) is used in most networks. If you are not sure if DHPC is used in your network, check it with your system provider.

1.2.1 Using Fixed IP address

When the PC is directly connected to the Instrument a Fixed IP address will have to be used with the PC configured in the local area connection. If the connection is made without a Hub or Switch, the connection has to be made with a Crossover Ethernet cable.

There are 2 types of Ethernet interfaces used on the M2x3 and i500.

Standard Ethernet interface, which is usually supplied along with a USB port which can be used to set the IP address.

An older XPORT interface (only early M2x3) which requires Lantronix software to be able to set the IP address. See section 1.3.

The IP address for both interfaces can also be set using the keypad/display on the M2x3.

1.3 Ethernet (XPort) communication

QDSP does not allow the setting of Local Port etc. on Ethernet (XPORT) devices (only early M2x3). If required these can be accessed using an internet browser.

Any internet browser available can be used to access the interface in the product, type in the IP address of the product as the required internet address.

The browser will communicate with the instrument and then display a request for password; press OK without entering a password and the ‘XPORT’ screen will be displayed.

2. MODBUS INFORMATION

2.1 introduction

The Modbus protocol is a widely supported open interconnect protocol originally designed by Modicon that can be enabled on the M2x3 and I500 via RS232, RS485, USB or Ethernet communication.

There are two Modbus protocol types: Modbus RTU for serial communication (and USB) and Modbus TCP for Ethernet communication. It is also possible to pass Modbus RTU communications over Ethernet.

On Serial Communication, Modbus is a single master multiple slave protocol suitable for a multi-drop configuration as provided by the RS485 connection. Up to 32 devices can be connected in this way. Single - drop RS232 or USB connection is also possible.

2.2 Transactions

Communication operates on a master-slave basis where only one device (the master) can initiate transactions called 'Requests'. The other devices (slaves) respond by supplying the requested data to the master. This is called the 'Request - Response Cycle'.

Master to slave request:

Device address Function Code nx8 bit data bytes Error check

Slave to master response:

Device address Function Code nx8 bit data bytes Error check

2.3 Request

This Master to Slave transaction takes the form:

Device address: Master addressing a slave (Address 0 is used for the broadcast address, which all slave devices recognise.).

Function code: E.g. 04 ask the slave to read its Input Registers and respond with their contents.

Data bytes: Tells the slave which register to start at and how many registers to read.

2.4 Response

This Slave to Master transaction takes the form:

Device address: To let the master know which slave is responding.

Function code: This is an echo of the request function code.

Data bytes: Contains the data collected from the slave.

2.5 Request - response cycle example

Ia 160.00 A = 16000* 10-2 A

Data type “T3” 32 bit unsigned

FE 00 3E 80(16)

Data held in Modbus addresses

30036(10) & 30037(10) 30036(10) - 30000(10) = 36(10) � 00 24(16)

2.6 Framing

There are two types of message framing for the serial communications, ASCII or RTU. iSTAT products supports RTU framing.

2.7 RTU framing

In RTU mode, messages start and end with a silent interval of at least 3.5 character times (t1-t2-t3-t4 as shown below).

The advantage of this mode of framing is that it enables a greater character density and a better data throughput. However, each message must be transmitted in a continuous stream. If a silent interval of more than 1.5 character times occurs before completion of the frame, the device flushes the incomplete message and assumes that the next byte will be the address field of a new message.

Start Address Function Data CRC Check End

t1-t2-t3-t4 8 bits 8 bits n x 8 bits 16 bits t1-t2-t3-t4

The Cyclic Redundancy Check (CRC) field is two bytes, containing a 16 bit binary value. The CRC value is calculated by the transmitting device, which appends the CRC to the message. The receiving device recalculates a CRC during receipt of the message, and compares the calculated value to the actual value it received in the CRC field. If the two values are not equal an error results. The CRC-16 calculation is an industry standard method used for error detection.

One frame is transmitted as 1 start bit, 8 data bits and 2 stop bit. If parity is selected then the frame is transmitted as 1 start bit, 8 data bits, and 1 stop bit.

Where n > 1 data is transmitted most significant byte first.

The CRC check is transmitted least significant byte first.

4. MODBUS ERROR RESPONSES

When a slave detects an error other than a CRC error, a response will be sent to the master. The most significant bit of the function code byte will be set to 1 (i.e. the function code sent from the slave will be equal to the function code sent from the master plus 128). The following byte will be an exception code indicating the type of error that occurred.

The slave will ignore transmissions received from the master with CRC errors.

An example of an illegal request and the corresponding exception response is shown below. The request in this example is to read registers 0201H to 0209H. If these addresses are not supported in the slave then the following occurs:

01 ILLEGAL FUNCTION The function code transmitted is not one of the functions supported by the slave.

02 ILLEGAL DATA ADDRESSES The data address received in the request is not an allowable value for the slave. Write to password protected registers.

03 ILLEGAL DATA VALUE The value referenced in the data field transmitted by the master is not within family for the selected data address. The register count is greater than 28 (functions 03 and 04).

06 SLAVE DEVICE BUSY The slave is engaged in processing a long duration program command. The master should re-transmit the message later when the slave is free.

5. MODBUS REGISTER MAPS

The Modbus register map consists of the following columns:

Code Function codes as described in Section 3.

Address 16 bit register address starting from zero.

Please Note:

Most Modbus master devices assume that 30001 or 40001 are subtracted from the defined address for the registers. The M2x3 and i500 subtract 30000 and 40000, meaning that the addresses may have to be offset by 1.

Contents Description of parameters assigned to registers.

MODBUS data types T1 etc. are described in section 6.6.

UNSIGNED INTEGER

family 0 ... 65535

one 16-bit register

SIGNED INTEGER family 32768 ... 32767

one 16-bit register

ASCII Family 32…159

16 bit registers (two ASCII codes per register)

Data type

BINARY FLAGS Each bit of a 16 bit register can be used as a binary flag

Indicator Each bit of a 16-bit register can be either assigned as flags or filled with binary data.

Values Definitions of settings, data values and any dependencies that exist between settings.

Register type Declares whether a register is to be read/write register (setting) or a read register (data).

Min, max step The minimum and maximum numerical family and the incremental step size.

Password There is a numerical password that allows save/abort settings and a factory accessible password constructed from the serial number that allows entry/exit to and from the calibration and configuration settings.
