5700 - SIL 3 HART®Multiplexer ModemG.M. International ISM0366-2
The 5700 is an electrical apparatus located in Safe Area or Zone 2, Group IIC, Temperature T4 Hazardous Area (according to EN/IEC60079‐15) within the specified operating tempera-
ture limits Tamb ‐40 to +70 °C.
The 5700 must be installed, operated and maintained only by qualified personnel, in accordance to the relevant national/international installation standards (e.g. EN/IEC60079‐14 Electri-
cal apparatus for explosive gas atmospheres - Part 14: Electrical installations in hazardous areas (other than mines)), following the established installation rules.
De‐energize power source (turn off power supply voltage) before plug or unplug the terminal blocks when installed in Hazardous Area or unless area is known to be nonhazardous.
Warning: substitution of components may impair suitability for Zone 2.
Explosion Hazard: to prevent ignition of flammable or combustible atmospheres, disconnect power before servicing or unless area is known to be nonhazardous.
Failure to properly installation or use of the equipment may risk to damage the unit or severe personal injury.
The unit cannot be repaired by the end user and must be returned to the manufacturer or his authorized representative. Any unauthorized modification must be avoided.
Warning
Installation
The 5700 is a HART®multiplexer modem housed in a plastic enclosure suitable for installation on customized Termination Board.
The 5700 unit can be mounted with any orientation over the entire ambient temperature range.
Electrical connection by polarized plug-in removable screw terminal blocks of conductors up to 2.5 mm² (for Write Protection terminal block) can be plugged in/out into a powered unit
without suffering or causing any damage. The wiring cables have to be proportionate in base to the current and the length of the cable.
Electrical connection to termination board can be plugged in/out into a unit without suffering or causing any damage (for Zone 2 installations check the area to be nonhazardous before
servicing).
Installation and wiring must be in accordance to the relevant national/international installation standards (e.g. EN/IEC60079-14 Electrical apparatus for explosive gas atmospheres - Part
14: Electrical installations in hazardous areas (other than mines)), make sure that conductors are well isolated from each other and do not produce any unintentional connection.
The enclosure provides, according to EN60529, an IP20 minimum degree of mechanical protection (or similar to NEMA Standard 250 type 1) for indoor installation, outdoor installation
requires an additional enclosure with higher degree of protection (i.e. IP54 to IP65 or NEMA type 12-13) consistent with the effective operating environment of the specific installation.
Units must be protected against dirt, dust, extreme mechanical (e.g. vibration, impact and shock) and thermal stress, and casual contacts. If enclosure needs to be cleaned use only a
cloth lightly moistened by a mixture of detergent in water.
Electrostatic Hazard: to avoid electrostatic hazard, the enclosure of 5700 must be cleaned only with a damp or antistatic cloth.
Any penetration of cleaning liquid must be avoided to prevent damage to the unit. Any unauthorized card modification must be avoided.
System topology
The HART®Mux 5700 can be used in five possible connection schemes, depending on the installation requirements and specific applications:
1. Direct connection to the field devices.
2. Connection through isolators installed on a DIN rail.
3. Connection through isolators installed on termination boards.
4. Connection through intrinsically safe barriers installed on a DIN rail.
5. Connection through intrinsically safe barriers installed on termination boards.
Each HART®Mux 5700 can manage a maximum of 256 channels, while the TB-D5001-HRT-003 (flat cables) and the other ones (terminal blocks) connect 64 and 32 channels
respectively. This means that up to 4 TB-D5001-HRT-003 and 8 other type can be cascaded.
Power supply and RS-485 line shall be connected only to the termination board where HART® Mux 5700 is mounted (the first of the chain).
LED indication
The front panel of the HART®Mux 5700 has three LEDs, which indicate the presence of the supply (POWER), the communication to the field (COMM.) and the specific operation
(OPER.) carried out by the multiplexer. An exhaustive explanation is given in Table 1.
Table 1: Meaning of the LEDs.
Three LEDs are available on the termination board. Two green LEDs are dedicated to the independent power supplies, while the yellow one indicates the status of the communication to
the modem.
Operation LED (OPER.) Field LED (COMM.) Power LED (POWER) Condition
OFF OFF OFF No power supply
OFF OFF Green slow flashing USB configuration
OFF OFF Green fast flashing Initial start-up
Yellow slow flashing Yellow intermittent flashing Green Building
OFF OFF Green Power on, idle state
OFF Yellow intermittent flashing Green Field ongoing communication
Yellow fast flashing Yellow intermittent flashing Green Scanning
Red fast flashing Yellow intermittent flashing Green Scanning, one or more loops disap-
peared
Red Red Red Hardware fault
HART®Mux configuration
Before using the HART®Mux 5700, baudrate and polling address must be configured. To carry out the configuration, connect the mini-USB to the PPC5090 adapter without supplying the
unit (the green power led flashes). Start the SWC5090 software (Figure 1). Choose the baudrate for the RS485 bus from the corresponding drop down menu. The polling address should
be a value from 0 to 62, unique within the bus. When the configuration is done, save the information to the device by pressing the “Store to device” button, remove the mini-USB and
mount the HART®Mux 5700 on the termination board.

12 5700 - SIL 3 HART®Multiplexer Modem G.M. International ISM0366-2
Figure 1: SWC5090 configuration software.
Start-up Sequence (Building)
At start-up the HART®Mux 5700 runs a 10s self-test procedure, indicated by the fast flashing of the power (green) LED on the unit and the slow flashing of the Communication (yellow)
LED on the termination board. Once this is over, the two LEDs stop flashing, hence indicating that the board has correctly been addressed by the HART®Mux 5700.
Then the Mux proceeds with the building operation, indicated by the slow flashing of the yellow operation LED: all the available channels are sequentially searched for smart devices to
allow direct communication between the host and the field slaves. The duration of this phase depends on a few variables: the number of connected termination boards, the actual
presence of connected devices, the number of configured retries on error, the configured search mode. The slow flashing of the yellow operation LED lasts until building is over.
Scanning
The scan is a specific operation made available by the HART®Mux 5700 that allows the user to monitor all connected field devices continuously. A selectable HART®command (1, 2 or
3) can be used to scan the slaves. A fast flashing of the yellow operation LED indicates that the scan is active. If one or more devices disappear, the operation LED light turns red. The
updated results of the scan operation are available in the Diagnosis, Boards Diagnosis and Display Values Window (see following sections) of the frame program.
FDT Technology
FDT (Field Device Tool) is an open standard for industrial automation that aims at controlling and monitoring networks of devices over many possible communication protocols, e.g.
HART®.
FDT requires a frame program running on a Host PC that loads the DTM (Device Type Manager) libraries describing the behaviour and the parameters available for each field device.
PACTware™ (Process Automation Configuration Tool) is the recommended frame program, which can be downloaded from several webpages, such as
http://www.icsgmbh.de/en/download-en/pactware-4-1.html, together with the instruction manual. The frame program requires a HART®Communication DTM, which can be found at the
same link.
In order to communicate with the hardware, an RS232/RS485 converter should be connected to the serial port of the Host. The suggested converter is the D1061S by GM International
(http://www.gminternationalsrl.com/index.php?pid=D1061S). The necessary settings are contained in the corresponding instruction manual.
The DTM of the HART®Mux 5700 is available at the GM International website (http://www.gminternationalsrl.com). To install it, download executable file and double click it; then, follow
on screen instructions. The DTM of the field devices should be fetched from the single manufacturers web pages.
The minimum required software tools, to be able to operate the HART®network, are the following:
 PACTware™ (4.1 recommended);
 HART®Communication DTM;
 DTM of HART®Mux 5700;
 DTM of connected field devices.

5700 - SIL 3 HART®Multiplexer ModemG.M. International ISM0366-2
HART®Mux 5700 FDT Setup
In order to access the HART®Mux 5700 functionalities, it is necessary to setup the frame program, e.g. PACTware™ (Figure 2).
Figure 2: PACTware™.
At the first start up after DTM installation a device catalog update is recommended.
Add the HART®communication DTM to the Host in the Project window on the left (right click on HOST PC, select Add device and pick up the HART®Communication DTM). Choose
“HART®multpliexer” as “Communication interface”. An example of configuration is given in Figure 3. Note that the baudrate should match the HART®Mux 5700 configuration. Note also
that start and end address should include all the desired HART®Mux polling addresses.
Figure 3: HART®Communication DTM configuration.
At this point two options are possible: if the user works online and all the hardware set up is in place, it is sufficient to connect the Communication DTM (right click on the Communication
DTM and select Connect) and to run an automatic scan (right click on the Communication DTM and select Topology Scan). The connection tree is fully searched, HART®Muxes and field
devices should automatically be located and the corresponding DTMs instantiated in the Project window. When more DTMs are possible for a single device, the Topology Scan window
waits for the user to select the desired one.
Alternatively, the user can design his connection tree offline, by adding the devices in turn in the Project window. HART®Muxes should be directly appended to the Communication
DTM, whereas the devices should be added to the specific HART®Mux they belong to, connected to the corresponding channel. Whichever solution the user prefers the final result
should be similar to Figure 4.

14 5700 - SIL 3 HART®Multiplexer Modem G.M. International ISM0366-2
Figure 4: Project example.
Note that each HART®Mux directly connected to the RS485 bus must have an individual address that matches the one specified in the Communication DTM. To change the addresses,
right click on the Communication DTM, select Change DTM address and specify, in case, a new address by picking up the desired HART®Mux in the main window. Communication DTM
must be in “disconnected” state to allow this operation.
Device-Specific Window Access
The main purpose of the HART®Mux 5700 DTM is to give the user the possibility of accessing the DTM of the connected devices. By double clicking on a device in the Project Window,
the corresponding DTM opens and displays all the information and features that the manufacturer made available (Figure 5).
Figure 5: Device-Specific Window Access.
HART®Mux 5700 Specific Windows
The HART®Mux 5700 DTM makes available different specific service windows (highlighted in Figure 6):

Two sections are available in this window, Rebuild (Figure 11) and Utility (Figure 13).
Figure 11: HART®Mux 5700 Service Rebuild Window.
At start-up all loops are rebuilt, i.e. the HART®Mux 5700 browses all channels searching for connected devices and it stores the identity information for each field slave. However, at any
point the user can ask the mux to perform the build operation again, on all or on a single loop.
The HART®Mux 5700 makes available the following services:
 Rebuild loops: all loops are rebuilt.
 Rebuild single loop number: a single loop in the range 1 to 256 can be rebuilt.
The yellow light indicates that the HART®Mux 5700 is rebuilding.
After any rebuild operation it is recommended to restart the Topology Scan on the specific multiplexer. To do so, right click on the HART®Mux 5700 in the Project Window and select

Figure 14: HART®Mux 5700 Display Values Window.
In this window the loop current, the percent of range, the primary variable value and the primary variable unit of the connected devices are displayed. Note that this window requires that
the HART®Mux 5700 is in scan mode. Depending on the specific scan command, a different subset of variables is available:
1. Command 1: primary variable value and unit.
2. Command 2: primary variable loop current and percent of range.
3. Command 3: primary variable loop current, primary variable value and unit.
Note: cumulative screens (BoardsDiagnosis and Display Values) are highly resource consuming for the operating system. Opening one window of each kind at a time is suggested.
The Device-Specific Status contains status information of the HART®Mux 5700 that can be accessed through the HART®Command 48 (Read Additional Device Status). Table 2
indicates how the data are organized.
