RTD Unit, Serial
Overview
The RTD unit serial function:
•
Communicates with an external RTD unit serial via the Slave Unit Protocol (SUP) and records the meas-
ured temperatures from the RTD unit
•
Provides the captured temperatures to the temperature supervision function
•
Monitors communication with the RTD unit
The RTD unit Serial function is set up structurally in the same manner as the RTD unit Ether. function. The
mode of operation is also identical (see
5.7.7.3 Communication with an RTD Unit
).
Application and Setting Notes
Parameter: Port
•
Default setting
(_:2311:103) Port
=
F
With the
Port
parameter, you set the slot for the communication module that will be used for the connection
with an external RTD unit.
If you want to connect the external RTD box to an Ethernet plug-in module, set the parameter
Port
=
Port
F
,
Port E
,
Port P
, or
plug-in module position
.
Parameter: Channel number
•
Default setting
(_:2311:105) Channel number
=
1
A serial communication module optionally uses 2 channels. With the
Channel number
settings, you set the
channel number (1 or 2) through which the RTD unit is connected to the device. The communication module
inputs are labeled with the channel numbers.
Parameter: Slave address
•
Default setting
(_:2311:106) Slave address
=
1
Use the
Slave address
parameter to define the device address of the RTD unit. If only one RTD unit is
connected to the serial bus, the default value
1
can be used. The same device address has to be set on the RTD
unit. The device address is important for distinguishing among several RTD units connected to a serial bus. Set
a unique device address (for example 1, 2 and 3 when connecting 3 RTD units) for each RTD unit and the same
device address for the parameter
Slave address
in the 3 RTD unit serial functions.
The following settings and information table shows only 1 of the 12 sensors, as the setting possibilities of the
12 sensors do not differ.
