4.7.3 - RS 485 SERIAL INTERFACE BY “TLCNV”
The instrument can be connected by a special cable to the TLCNV
device (mod. C - TTL/RS485 interface), by means of which it is
possible to connect the regulator with a net to which other
instruments (regulators of PLC) are connected, all depending
typically on a personal computer used as plant supervisor.
Using a personal computer it is possible to acquire all the function
information and to program all the instrument’s configuration
parameters.
The software protocol adopted for the instrument is a MODBUS
RTU type, widely used in several PLC and supervision programs
available on the market (Y and Z series protocol manual is
available on request).
If the instrument is used with TLCNV program by the parameter
"t.Ad" the station Address.
Set a different number for each station, from 1 to 255.
Note: The baud-rate are fixed at 9600 baud.
TLCNV interface is directly supplied by the instrument.
