M1100S WirelessHART Module

WirelessHART standard is developed together by HCF member companies, main wireless device manufacturers and industrial users under the guidance of the HART Communication Foundation (HCF). WirelessHART is a wireless mesh network communications protocol, specially designed for process automation application.

WirelessHART adopts mesh topology network technology, safe and stable with 2.4 GHz ISM frequency band, and all the information is packaged in one packet, to realize data transmit through DSSS (Direct Sequence Spread Spectrum) and FHSS (Frequency Hopping Spread Spectrum) technology based on IEEE802.15.4. A WirelessHART network consists of three key elements: WirelessHART field devices, WirelessHART gateway and WirelessHART network manager, also supports WirelessHART adapter, to let existing HART devices access WirelessHART network, and supports WirelessHART handheld devices, to connect adjacent WirelessHART devices. Figure 1.1 shows the complete WirelessHART network structure.

M1100S WirelessHART module is a wireless communication module compliant with HART7.4 protocol, and is the core part of WirelessHART field device. M1100S periphery provides TTL serial port and control interface. Through the serial port, the M1100S communicates with special customized instrument board, to combine a complete WirelessHART field device. The control interface is used to control input and output of the serial port. M1100S supports all the mandatory commands of fieldbus device in HART7.5 protocol and Burst mode.

M1100S Module Composition and Overall Framework

Serial port communication mode is used between M1100S module and instrument board, with half-duplex communication mechanism, to complete information interaction between the instrument board and M1100S module. Instrument board provides maintenance port to realize parameter configuration of M1100S module, process monitoring, and other functions. Typical application scenarios of M1100S module are shown in picture below.

Communication

The user instrument board is connected with module through a standard TTL serial port (UART) and two control lines.

This picture is sequence chart for instrument card sending data to WirelessHART M1100S. 0xFF is used as preambles. There must follow at least two preambles after pulling down tpre of RTS.

This picture is sequence chart for WirelessHART module sending data to instrument board. The M1100S starts to transmit preambles immediately after it pulls down the CD signal. The default number of preambles sent is 6. Assumed the instrument board requires at least two correct preambles, it has twake time to be ready for reception after CD signal is pulled low.

A valid communication includes request and response. Both instrument board and M1100S can act as master and shall be able to act as slave. To every request there always must be a response. Transmission of the response must be within 32ms after receipt of a request. If no response is received by the requester within 32ms, the requester may send the request again. The M1100S does retry up to 3 times. At the same time, to avoid conflict, continuous request is not allowed be sent in a period of 4.5s after the reception of a response.
