TELENET MONITORING/SUPERVISION SYSTEM
To connect the NECTOR to the TeleNET monitoring and supervision system perform the following
steps:
1. Assign a unique network address using the 3rd level variable Ad , and set Ser=0 .
2. The terminals of the TeleNET connection are indicated with RS-485(A) and RS-485(B) on the
NECTOR board.
3. Observe the identification (A) and (B) of the RS-485 line, remembering that on the 2TWRS485
interface the terminal 3= (A) and 4=(B).
4. Do not make star connections on the RS485 line.
IMPORTANT:
During configuration, under “Module” select "
PLUS Expert Series Tool ". Under
“Module” it is also possible to configure:
-
“TWMT tool” to display only the ambient temperature probe value;
-
“TWMUR tool” to display the value of the probe configured as a humidity probe (parameter
An5=1 or An5=2);
-
“TWMP tool” to display the value of the probe configured as pressure probe (parameter
An5=3).
The following is the typical connection of a NECTOR in a TeleNET network.
MODBUS-RTU PROTOCOL
To insert the panel into an RS485 network with Modbus-RTU protocol, set the Ser, Ad, Bdr and Prt
parameters correctly, and follow the diagram below. Refer to the MODBUS-RTU_PLUSR200
