- 4. 1 1.0 SCOPE This document is a User Interface Specification for the WebMaster® Modbus/TCP product feature. This is a mapping of the various dynamic variables to their Modbus/TCP register locations. This document supports the Modbus feature in the following controller software versions: S825v022, s826v022, s827v022, s829v022 2.0 INTRODUCTION The WebMaster® product supports TCP/IP communications on 3 different network interfaces (USB, modem, and Ethernet). All configurations of set points are accomplished with a computer running a browser (such as Microsoft Internet Explorer) connected to the WebMaster® over one of these interfaces. The Modbus/TCP option allows the WebMaster® to communicate with PC-based applications such as WonderWare and Intellution HMI/SCADA programs, Building Energy Management systems, Distributed Control Systems (DCS), as well as stand-alone HMI devices. The WebMaster® is a Modbus Server, meaning that it is capable of responding to requests from the HMI device. The WebMaster® cannot initiate the flow of information, for example, it will not immediately send a new alarm message. It will wait until the HMI device requests the current data contained in specific register locations. In version 10 or higher, the HMI software can be used to change WebMaster® set points. This manual is divided into two sections, Modbus Read and Modbus Writes. If the HMI device does not directly support Modbus/TCP protocol, then a protocol translation gateway may be required to convert from Modbus/TCP to a protocol that the device supports. Please note that Modbus/RTU requires a serial interface, not Ethernet, and therefore is not directly compatible with the WebMaster®.
- 5. 2 3.0 OVERVIEW Modbus/TCP is a form of Modbus that uses the TCP/IP layers as a base layer for controlling the communications between different devices. The Modbus/TCP protocol supports multiple types of data transactions, from reading single bits per transaction, to advanced object-oriented operations. However, to ensure the most compatible system available, the simplest function set is to be made available. The Modbus/TCP protocol has each transaction type classified in to conformance classes, to ensure consistency and interoperability. Class 0 is the simplest, and allows for reading and writing of multiple 16-bit registers. The Modbus/TCP feature of the WebMaster® will support reading and writing of these 16-bit registers, which allows the WebMaster® to establish a block of data which contains all the process variables, set points, alarms and input/output statuses that are to be made public to a Modbus/TCP client. This block of data is packaged so that it can be read in 16-bit chunks (or registers) at a time, regardless of the type of data within it. In the following sections, the formatting, storing, and reading of this data are described. 4.0 MODBUS/TCP DRIVER 4.1 MODBUS PROTOCOL The Modbus protocol, as well as the TCP extension, is well documented in the specifications which are available at http://www.modbus.org, a website established by the Modbus Organization for supporting and organizing the Modbus protocol. Only the use of the protocol is documented here. 4.1.1 TCP The Modbus/TCP extension includes 7 additional bytes to the original Modbus protocol, which allows for transport over the TCP/IP layers. MBAP Header Function Code Data The MBAP Header (Modbus Application Protocol Header) consists of 7 bytes of information:
- 6. 3 Transaction Identifier 2 bytes identification of Request/Response transaction – copied from request to response Protocol Identifier 2 bytes 0 = Modbus protocol Length 2 bytes number of following bytes – includes the unit identifier Unit Identifier 1 byte identification of remote slave, can be used for broadcasting (not supported) The Unit Identifier has a special consideration in the WebMaster® implementation. If the value is 0, then the request is considered to be a broadcast message; therefore the packet will be processed, and no response will be generated. If the value is anything else, the packet will be processed and a response will be generated. Normally the Slave ID will be set in the HMI client software to 1. The broadcast Unit Identifier address is not supported as of this release, as the only function code supported is Read Holding Registers; therefore, a response is required at all times. 4.1.2 Function Codes The Modbus/TCP Server feature supports the following function codes: Function Code 3 (FC3), Read Multiple Registers, which allows the reading of up to 125 16-bit registers, or quantities, within a single request/response cycle. Function Code 16 (FC16), Write Multiple Registers, which allows the writing of up to 125 16-bit registers, or quantities, within a single request/response cycle. Function Code 6 (FC6), Write Single Registers, which allows the writing of a single 16-bit register within a single request/response cycle. FC3 and FC16 have a 125-register limitation, which was established for the Modbus/TCP standard to maintain consistency with the original Modbus protocol standard, even though a TCP/IP packet can support more data. Request Function Code 1 byte 0x03 Starting Address 2 bytes 0x0000 to 0xFFFF Quantity of Registers 2 bytes 1 to 125 (0x01 to 0x7D) Response Function Code 1 byte 0x03 Byte Count 1 byte 2 x N* Register Values N* x 2 bytes
- 7. 4 *N = quantity of registers Error Function Code 1 byte 0x03 Exception Code 1 byte Any unsupported Function Code request will be returned with an error response. The error response is also applied to a request for too much data, or data at a register address that is not present. 4.2 TCP/IP INTERFACE The Modbus/TCP interface is attached to the TCP/IP stack that is implemented within the WebMaster® product, and will listen to all communications that come in on Modbus/TCP registered port 502. Up to 10 connections/sockets are possible at one time. If there are 10 active connections, any attempt at any more connections is ignored. Once a connection has been established, it will be closed after 1 minute of inactivity. 4.3 DATA REFRESH To ensure that the Modbus/TCP client has the most recent data available to it, the Modbus/TCP periodically refreshes the data by reading the selected data and storing it in the specific locations within the tables. The refresh is performed every four seconds, so the client application should not request data more frequently than once every 4000 msec. 4.4 DATA ENCODING Modbus uses a ‘big-endian’ representation for addresses and data items. This means that when a numerical quantity larger than a single byte is transmitted, the MOST significant byte is sent first. The following sub-topics describe the different types of encoding and show how the data is encoded as it is within the Modbus/TCP packet. Most client drivers will extract the data from the packet in the correct format for use/display within the client environment. 4.4.1 Binary Binary data is used for digital input or alarm states that can be represented as a 1 or a 0. A binary item is represented as a single bit within a data word. All binary data is packed in to 16-bit data words, therefore a single register contains 16 bits of binary data, each having a specific meaning.
- 8. 5 value 1st 2nd 0xAA55 (101010100101) 0xAA (10101010) 0x55 (01010101) 4.4.2 16-Bit Word (short) A 16-bit word item is transmitted with the MOST significant byte first. FC3 reads 16-bit items at a time; therefore, each of these data items will fit within one register that is read. value 1st 2nd 0x1234 0x12 0x34 4.4.3 32-Bit Word (Integer) Integer data is used for encoding the status message, input or output state, relay control mode, and relay output mode. A 32-bit word item is transmitted with the MOST significant byte first, then the next MOST significant, until all bytes are transmitted. FC3 reads 16-bit items at a time; therefore, two registers are required to read each 32-bit data item. 1st register 2nd register Value 1st 2nd 1st 2nd 0x12345678 0x12 0x34 0x56 0x78 4.4.4 Float Inverse Float Inverse data is used to represent sensor input and control output dynamic data. A float is 32-bits within the WebMaster product; therefore is transmitted just as a 32-bit word item is. FC3 reads 16-bit items at a time; therefore, two registers are required to read each float data item. Hexadecimal Representation of a 32-bit Floating Point Number 1st Word 2nd Word 1st Byte 2nd Byte 1st Byte 2nd Byte 0x12 0x34 0x56 0x78 Since the “Float Inverse” convention is used in MODBUS, this means that the high and low order "words" are actually swapped. Therefore, the HMI must perform the word swap of the register contents in order to convert and express the floating point number properly in normal decimal notation.
- 9. 6 32-bit Float Inverse Hexadecimal Representation of a Floating Point Number 1st Word 2nd Word 1st Byte 2nd Byte 1st Byte 2nd Byte 0x56 0x78 0x12 0x34 Example: 5,000.00 decimal is 0x459C4000 hexadecimal float and 0x4000459C hexadecimal inverse float. 4.4.5 Strings Strings are used for the System Summary page header data, custom names, and units of measure. A string is a group of 8-bit data items having a fixed length. The first character of a string is transmitted first, followed by the remaining characters. Modbus reads 16-bit items at a time; therefore, a single register contains two characters of the string. To simplify string storage/transfer, each string should be of an even-byte length. 1st register 2nd register 3rd register 4th register value 1st 2nd 1st 2nd 1st 2nd 1st 2nd ‘Walchem’ ‘W’ ‘a’ ‘l’ ‘c’ ‘h’ ‘e’ ‘m’ ? Strings are read by the client application as Hex and decoded into ASCII. Example: Address Hex value ASCII "Level 2" 6001 0x4C65 "LE" 6003 0x7665 "VE" 6005 0x6c20 "L " 6007 0x3200 "2 " 4.5 DATA DICTIONARY - READS The following tables detail the Modbus addresses required to access each item of the public data.
- 10. 7 4.5.1 Addressing (0- or 1-Based) The addressing within the Modbus/TCP protocol (that is, the data within the physical packet) is 0-based, meaning the first element/item to be accessed is referenced by address 0. The Modbus standard for handling and displaying the data is 1-based, meaning the first element/data item to be access is referenced by address 1. Most client applications handle this by having the user enter the 1-based number, and then subtract 1 to revert to the 0-based addressing required at the protocol level. Some client applications allow the user to enter the 0-based number, or a combination, depending on how it is configured. The addresses defined within the following table are 1-based, as the majority of the client applications work with this method. 4.5.2 Header Data, Custom Names and Units of Measure Header data consists of strings to display the name and location programmed in the product. Custom names of inputs and outputs describe the purpose of the device connected. Units of measure changes made in the controller can be automatically be updated on the HMI. Refer to section 4.4.5 Strings for the method to extract the string data. For example, to read the Controller Name, a Read Holding Register request is generated with address 40001 and a register quantity of 16.

- 11. 8 4.5.3 Alarm Data Alarm states are bit-based (Binary), with up to 16 alarms encoded within each register. To access an individual alarm state, the register is read and the specific bit of the register is checked. Refer to section 4.4.2 16-Bit Word (short) for the method to properly extract the data. For example, to check the Modem Failure Alarm, a Read Holding Register is generated with address 41001 and a register quantity of 1. When the data is returned, and is extracted, it is bit-or’ed with 2 to determine the state.

- 16. 13 4.6 DATA DICTIONARY - WRITES The following tables detail the Modbus addresses required to modify each item of the public data. 4.6.1 Addressing (0- or 1-Based) The addressing within the Modbus/TCP protocol (that is, the data within the physical packet) is 0-based, meaning the first element/item to be accessed is referenced by address 0. The Modbus standard for handling and displaying the data is 1-based, meaning the first element/data item to be access is referenced by address 1. Most client applications handle this by having the user enter the 1-based number, and then subtract 1 to revert to the 0-based addressing required at the protocol level. Some client applications allow the user to enter the 0-based number, or a combination, depending on how it is configured. The addresses defined within the following table are 1-based, as the majority of the client applications work with this method. 4.6.2 Dynamic Data - Writes Dynamic data for Modbus writes are float inverse. To modify an individual Set Point, 2 registers are required to be written to. Set points with (int) shown will be rounded to an integer if not entered as one. Refer to section 4.5.4 Float Inverse for the methods to properly modify the data. All writable registers may also be read. For example, to modify the Low-low alarm set point on sensor input hardware channel 1, a Write Holding Register is generated with address 20641 and a size of 2. The second chart below indicates the range of allowable set points for each type of sensor.
