Detailed explanation of HART communication function

（1） Core specifications

Communication mode: Serial half duplex, start stop synchronization (1-bit start/8-bit data/1-bit odd parity/1-bit stop)

Applicable standard: HART Protocol Revision 5.7 (compatible with HART 5/6/7 devices)

Transmission rate: 1200bps ± 1%

Modulation method: Binary phase continuous FSK (1:1200Hz ± 1%); 0：2200Hz±1%）

Frame length: 5-267 bytes (including address, command, data, and checksum bytes)

Response time: Maximum 28 characters (256.7ms)

No response timer: Main device 33 characters (305ms); From device 41 characters (380ms)

（2） Connection and Data Characteristics

Device connection: up to 16 devices/modules; Multiple station connections up to 5 units/channel (input devices only)

Data processing: The maximum number of HART variables per module is 32 points, connected through the% Z terminal, and only supports input

Data refresh cycle: 1 second per device (17 seconds per ESB bus connection for 16 devices)

System configuration: Supports dual redundancy, requiring two modules to be installed in adjacent slots (odd+even) of the same node unit

（3） Data flow

The module communicates with on-site HART devices to collect analog data and HART variables;

Data is stored in the I/O image area of the module;

FCS reads I/O image area data through access modules;

FCS calls data through functional block I/O terminals and processes it uniformly with ordinary analog/digital signals.

Installation and compatibility requirements

（1） Hardware compatibility

1. On site Control Unit (FCU)

Compatible models: AFV30D-S41  11, AFV30S-S31-11, AFV30S-341  11

Power requirements: PW481-11, PW482-11, or PW484-11 power modules are required

2. Node unit

ESB bus node units: ANB10D-4  1, ANB10S-3  1, ANB10S-4  1, ANB10D-4  3, ANB10S-3  3, ANB10S-4  3

Optical ESB bus node units: ANB11D-2  3, ANB11D-4  3, ANB11S-1  3, ANB11S-2  3, ANB11S-3  3, ANB11S-4  3

（2） Software and Engineering Requirements

Control function: VP6F1700 on-site control station control function (applicable to AFV30 )

Engineering Tool: VP6E5100 Standard Builder Function

EMC requirement: Shielded cables are required (one layer of shielding can be shared across all channels)

（3） Installation precautions

Redundant configuration: Dual redundant modules need to be installed in adjacent slots (odd+even), and the terminals should use dual redundant pressure clamp terminals

Wiring requirements: Separate the wiring of analog signals and digital signals to avoid interference; The resistance of thermocouple wiring needs to be consistent

Environmental restrictions: Operating temperature -20 to 70 ℃, avoid direct sunlight and corrosive gases

Explosion proof isolation: The distance between non intrinsic safety modules should be ≥ 50mm, and insulation partitions should be installed (refer to the relevant explosion-proof document)
