New HIM loop interface converts HART to
MODBUS RTU
The Moore Industries HIM Smart HART loop interface and monitor with a HART-to-MODBUS option converts the digital signal from a smart HART instrument to a standard MODBUS RTU protocol output
This allows HART temperature, pressure, level, flow and pH transmitters to interface directly with MODBUS control systems For added security, the HIM provides for a redundant MODBUS communications link identical to the primary link
Communications continue uninterrupted even if one of the MODBUS links is compromised.
The converter also provides a 4-20mA analogue output that may be mapped to any HART variable (primary, secondary, third, or fourth).
This allows an additional measurement to be continually tracked.
Dual alarm trip outputs can be individually configured to warn of high/low process conditions.
They can also be set to alert the user if the monitored device and/or HART monitor itself is in a fault condition.
This includes use of the HART protocol status bits to indicate a smart transmitter cold start, field device malfunction, or that the primary variable analogue output is fixed, saturated or out of limits.
The HART Interface and Monitor sets up quickly and easily using Moore Industries single window configuration software equipped with HelpMap, a comprehensive, searchable web-based help system that smoothly guides the user from hook-up to start-up.
