Fieldgate SFG500/SFM500 Safety
Endress+Hauser 3
1Safety
1.1 Designated use
Fieldgate SFG500 is a system component that provides an independent access route to a
PROFIBUS network. It may be used in a variety of applications that are supported by specific
operating modes. The operating modes are determined by an optional memory card
(Fieldgate Module SFM500).
With Fieldgate Module "Asset Monitor", Fieldgate SFG500 listens to PROFIBUS traffic and
presents the results in its web server. The user is able to check the status of devices according
to Namur NE107. Events on the network can also be logged, and e-mails sent if particular
conditions are met. Apart from setting PROFIBUS device addresses, Asset Monitor cannot be
used to configure devices. In this case Fieldgate SFG500 must be used together with
FieldCare as described in Operating Instructions BA00071S/04/en.
1.2 Installation, commissioning and operation
Fieldgate SFG500 has been designed to operate safely in accordance with current technical
safety and EU directives. Field devices, links, junction boxes, cables and other hardware used
in conjunction with the Fieldgate SFG500 module must also be designed to operate safely in
accordance with current technical safety and EU directives.
If devices are installed incorrectly or used for applications for which they are not intended,
or if the Fieldgate SFG500 module is not configured correctly, it is possible that dangers may
arise. For this reason, the system must be installed, connected, configured, operated and
maintained according to the instructions in this and the associated manuals: personnel must
be authorised and suitably qualified.
1.3 Operational safety
When using Fieldgate SFG500 as an Asset Monitor, the instructions in Chapter 1.3 of
BA0070S/04/en, Fieldgate SFG500: Installation and Commissioning, shall be observed.
1.4 Supplementary documentation
Table 1-1 indicates the documents, planned and realized, containing safety relevant
information, installation, commissioning and operating instructions for Fieldgate SFG500
and its web server.
The manual PROFIBUS guidelines contains information on how to design and install a
PROFIBUS network, in particular on how to ground the network in order to avoid
electromagnetic interference on the bus.
All documentation available at the time of release is included on the Fieldgate SFG500 CD-
ROM and can be installed by default in Start=>Programs=>Endress+Hauser=Fieldgate
SFG500=>Manuals from it.

Fieldgate SFG500/SFM500 Function and System Design
Endress+Hauser 5
2 Function and System Design
2.1 Function
The Asset Monitor functionality of Fieldgate SFG500 is obtained when a Fieldgate Module
SFM500 with corresponding software is inserted in its memory card slot. In Asset Monitor
mode, Fieldgate uses its parallel path to a PROFIBUS DP network to monitor traffic, build up
a list of the bus participants and to monitor bus events. It offers the following functions:
• Live list of all device on the bus with status information to Namur NE107
• Audit trail of device events with type of event and time stamp
• E-mail notification of device events
When Fieldgate SFG500 is operating in Asset Monitoring mode, it can still be used together
with FieldCare. The additional functions are presented in the "Embedded Web Server" feature
of the SFG500 DTM, see Operation Instructions BA00071S/04/en, Fieldgate SFG500:
Operation as Access Point.
2.2 System design
Fig. 2.1 shows Fieldgate SFG500 operating as an Asset Monitor in a PROFIBUS network.
Fig. 2-1: System architecture for Fieldgate SFG500 operating as an asset monitor
The control network comprises one or more PLCs or DCSs and one or more PROFIBUS DP
segments. Connected to the PROFIBUS DP segment are PROFIBUS DP slaves, Remote I/Os
and segment couplers or links. Through its Ethernet port (LAN1), Fieldgate SFG500 allows
a Web browser access to the information it has collected. If there is more than one segment
in the PROFIBUS DP network, a separate Fieldgate SFG500 is required for each.

be used to change the bus parameters, however, it is important to note that all the PROFIBUS
DP devices, including couplers and links, connected to a particular network must have the
same communication settings

Auto Mode Fieldgate SFG500 detects the PROFIBUS parameters and sets its own address
– The detected PROFIBUS parameters are displayed
– Overwriting is disabled
Passive Mode Fieldgate SFG500 listens to the bus but does not enter traffic as Master Class 2
– FieldCare cannot be used with this mode
Manual Mode Writing is enabled and the user can set the PROFIBUS parameters
– Fieldgate must use the same parameters as all other PROFIBUS equipment
otherwise communication will fail
– A return to manual mode will cause all changes to be lost and Fieldgate will
detect the PROFIBUS parameter and set its own address
Baudrate

Timing Parameters
Slot Time Monitoring time – 'Wait for receipt' – of the senders (Requestor) of telegram for
the acknowledgement of the recipient (Responder). After expiration, a retry occurs
in accordance with the value of 'Max. telegram retries'.
Min. Station Delay Time Shortest time period that must elapse before a remote recipient (Responder) may
send an acknowledgement of a received query telegram.
The shortest time period between receipt of the last Bit of a telegram to the
sending of the first Bit of a following telegram.
Max. Station Delay Time Longest time period that must elapse before a Sender (Requestor) may send a
further query telegram.
Greatest time period between receipt of the last Bit of a telegram to the sending of
the first Bit of a following telegram.
The Sender (Requestor, Master) must wait at least for this time period after the
sending of an unacknowledged telegram (e.g. Broadcast only) before a new
telegram is sent.
Quiet Time Time delay that occurs for modulators (Modulator-trip time) and Repeaters
(Repeater-switch time) for the change over from sending to receiving.
Setup Time Minimum period "reaction time" between the receipt of an acknowledgement to the
sending of a new query telegram (Reaction) by the Sender (Requestor).
Token Rotation Time Pre-set nominal Token cycling time within which the Sender authorization (Token)
will cycle around the ring. How much time the Master still has available for sending
data telegrams to the Slaves is dependent on the difference between the nominal
and the actual token cycling time.
Gap Update Factor Factor for determining after how many Token cycles an added participant is
accepted into the Token ring. After expiry of the time period G*TTR, the Station
searches to see whether a further participant wishes to be accepted into the logical
ring.

Slave Settings allows the user to change the address of the selected PROFIBUS device,
e.g. during commissioning of the network.
1. Open the Network menu by clicking on the Network tab
2. Click on Slave Settings
– The PROFIBUS slave settings window opens:
3. Select the address of the device whose address must be changed from the Current
Address drop-down menu
4. Select the address the device should be given in the New Address drop-down menu
5. Press Apply to write the change of address to the device
– Pressing Cancel will discard all changes and leave the device with its old address
– A possible reason for a failure to change an address is that the device is locked
