Product Description
The X-HART 32 01 module is a 32-channel communication module, intended for use in the
programmable electronic system (PES) HIMax.
The module is inserted into any of the base plate slots with the exception of the slots reserved
for system bus modules. For more information, refer to the System Manual (HI 801 001 E).
The connector boards can be used to allow the module to be combined with analog input or
output modules.
The HART protocol is operated on the module. HART is used for digital field communications
during which the HART signal is superimposed onto the (4…20 mA) analog current signal.
The HART signal is used to transfer the measuring and device data to sensors or actuators. The
X-HART modules transfer the HART data to the assigned X-COM module within the HIMax
system. The X-COM module transfers the HART data via the HART over IP protocol to the host
(asset management system or HART OPC server).
The X-COM module and the assigned X-HART modules form a I/O system as referred to in the
HART specification.
The module has been certified by the TÜV for safety-related applications up to SIL 3
(IEC 61508, IEC 61511 and IEC 62061) as well as Cat. 4 and PL e (EN ISO 13849-1).
Refer to the HIMax Safety Manual (HI 801 003 E) for more information on the standards used to
test and certify the module and the HIMax system.
3.1
Safety Function
The safety function of the X-HART module includes the following points:
HART Deactivation of one channel: If the module is shut down, the HART channels are
safely deactivated in accordance with SIL 3 (HART channels de-energized).
HART Filtering: HART write access to HART transmitters or sensors is locked in accordance
with SIL 3. If the HART filtering function is deactivated on the HART module, the
corresponding analog input or output channel is writeable.
3.1.1
Reaction in the Event of a Fault
If a fault occurs, the module adopts the safe state.
The X-HART module is interference-free to the analog input or output modules connected in the
same circuit.
The module activates the
Error
LED on the front plate.
3.2
Scope of Delivery
The module must be installed on a suitable connector board to be able to operate. If a Field
Termination Assembly (FTA) is used, a system cable is required to connect the connector board
to the FTA. Connector boards, system cables and FTAs are not included within the scope of
delivery.
The connector boards are described in Chapter 3.6, the system cables are described in Chapter
3.7. The FTAs are described in own manuals.
