3.3 Connection of service tool Ensite
3.3.1 Communication via the Enraf field bus line
By default, the 973 SmartRadar LT is set on transmission address 00. The 973 SmartRadar LT, and also
other types of Enraf gauges, can be connected in parallel to the Enraf field bus line. Each instrument must
have its unique transmission address.
The items can be programmed using the Portable Enraf Terminal, which is connected via the optional Infra-
red connector. If this option is not present, items can be programmed remotely.
SmartRadar LT connected to an 858 CIU
Temporary disconnect the RS-232C connection from the Entis+ (or other host) and connect it to a service
PC where the service tool “Ensite” is running (refer to figure 3.2a).
Mind the relation for the transmission addresses per transmission line of the 858 CIU:
TL1 (addresses: 00 - 29), TL2 (addresses: 30 - 59), TL3 (addresses: 60 - 99)
The SmartRadar LT can be connected to the desired transmission line, although its address is still at
default. Thus a SmartRadar LT with default transmission address 00 can be connected to transmission line
2 (suitable for transmission addresses 30 - 59). Due to the mechanism that the request from the host (Ensite
service tool) is transmitted over all three transmission lines, the SmartRadar LT receives the commands.
However, when the SmartRadar LT is connected to transmission line 2 or 3, there is no response.
This concept only works if
one
new SmartRadar LT is powered with the default transmission address 00.
Also, there may not be an operational gauge with transmission address 00. If such a gauge exists, do switch
it off temporarily.
Continue with section 3.3.4, programming communication parameters.
SmartRadar LT connected to an 880 CIU Prime
HostPort 2 from the CIU Prime must be available for the connection of a service PC where the service tool
“Ensite” is running (refer to figure 3.2b).
To communicate via HostPort 2, the CIU Prime must be configured to CIU 858 emulation mode on
HostPort 2. If HostPort 2 is in use, temporary disconnect it and temporary re-configure the CIU Prime for
CIU 858 emulation via HostPort 2.
This concept only works if
one
new SmartRadar LT is powered with the default transmission address 00.
Also, there may not be an operational gauge with transmission address 00. If such a gauge exists, do switch
it off temporarily.
Continue with section 3.3.4, programming communication parameters.
SmartRadar LT connected to another type of host
Temporary disconnect the Enraf field bus line from the host.
Use a 847 PET (Portable Enraf Terminal) with optional RS-232C PET Interface as protocol converter
between Enraf field bus signal and RS-232C to the service PC where the service tool “Ensite” is running
(refer to figure 3.2c).
This concept only works if
one
new SmartRadar LT is powered with the default transmission address 00.
Also, there may not be an operational gauge with transmission address 00 connected to the Enraf field bus
line. If such a gauge exists, do switch it off temporarily.
