Page 14: Introduction To Hart
Getting Started Introduction To HART HART® Field Communications Protocol is widely recognized as the industry standard for digitally enhanced 4-20 mA smart instrument communication. Use of the technology is growing rapidly, and today virtually all major global instrumentation suppliers offer products with HART communication. The HART protocol provides a uniquely backward compatible solution for smart instrument communication as both 4- 20 mA analog and digital communication signals are transmitted simultaneously on the same wiring. - Page 15 Getting Started The HART FSK signaling enables two-way digital communication and makes it possible for additional information beyond just the normal process variable to be communicated to or from a smart field instrument. The HART protocol communicates at 1200 bits per second without interrupting the 4-20 mA signal and allows a host application (master) to get two or more digital updates per second from a field device.

Page 16: Introduction To Gwy-800-B
Getting Started Introduction To GWY-800-B GWY-800 is a protocol converter as well as the HART modem. This converts the HART digital signal to a serial communication protocol (e.g. MODBUS). This allows various HART field devices to interface directly with serial protocol (MODBUS) based monitoring and control systems. -
Page 17: Configuration Of Gwy-800-B (Ibm Download)
Getting Started Configuration of GWY-800-B (IBM Download) User MUST download Project, PLC1 driver and HART in Gateway before installing any system using Gateway. Gateway can accept drivers and configuration data on COM1 port. User needs a special IBM download cable for downloading configuration in Gateway. All configurations can be downloaded only form Serial port (Port 1). The other port is dedicated for HART. -

Page 20: Gateway Modes
GWY-800-B Features Gateway Modes Gateway has two modes of operation: Master-Master and Master-Slave. Before explaining these modes further Master and Slave concept should be explained. Master: Master is a Device / device driver which initiates communication. Slave: Slave is Device / Device driver which processes Master’s query, takes necessary action and responds to the query, if necessary. - Page 21 GWY-800-B Features Let us see the example of Master-Master mode as shown in the picture below: Configure Gateway ports as: PLC1 Protocol: Modbus (Gateway as Master) PLC2 Protocol: HART Doc No: UMAN\GWY-800-B\0706 REVISION 0...

Page 22: Master-Slave Configuration
GWY-800-B Features 4.1.2 Master-Slave Configuration In this mode, one of the Gateway ports is a master and other is the slave so the devices connected on these ports are slave and master respectively. Blocks do not control data transfer in this mode. Data transfer takes place only when Master Device, connected on slave port of Gateway, sends a request to read / write data. -
Page 23: Repeat Cycle
GWY-800-B Features Repeat Cycle User can control Block execution by using the Repeat Cycle field. This number decides whether the Block will be executed in each cycle. Larger the number lower the priority of the Block. Range for Repeat Cycle setting is 1-99. Repeat Cycle = 1 …………... -
Page 24: Error Indication Bit
GWY-800-B Features In the above example, number of control bits are 36. So 36 / 16 = 2 (Number of words in control field) 36%16 = 4 (i.e. Non-zero so add 1 in the number of words in the control field), so number of words in control field are 2+1 = 3. -

Page 31: A Flexible Applications
Appendix Flexible Applications HART is principally a master/slave protocol which means that a field (slave) device speaks only when spoken to by a master. Two masters (primary and secondary) can communicate with slave devices in a HART network. Secondary masters, such as handheld communicators, can be connected almost anywhere on the network and communicate with field devices without disturbing communication with the primary master. - Page 32 Appendix “Burst” is an optional communication mode (Figure 5), which allows a single slave device to continuously broadcast a standard HART, reply message. This mode frees the master from having to send repeated command requests to get updated process variable information. The same HART reply message (PV or other) is continuously broadcast by the slave until the master instructs the slave to do otherwise.
- Page 33 Appendix HART communication is command based, i.e., a master issues a command and the slave responds. Three types of HART commands provide read/write access to information available in HART-compatible field instruments. Universal and Common Practice Commands are defined in the HART protocol specifications. The third type, Device Specific Commands, provide freedom for product specific parameters or functions unique to a particular device.
