Controller N1100
NOVUS AUTOMATION 8/8
SERIAL COMMUNICATION
The indicator can be supplied with an asynchronous RS-485 digital
communication interface for master-slave connection to a host
computer (master).
The indicator works as a slave only and all commands are started by
the computer which sends a request to the slave address. The
addressed unit sends back the requested reply.
Broadcast commands (addressed to all indicator units in a multidrop
network) are accepted but no reply is sent back in this case.
CHARACTERISTICS
RS-485 compatibility with two-wire connection from the host to up to
31 slaves in a multidrop network topology. Up to 247 units can be
addressed by the MODBUS RTU protocol. Maximum network
distance: 4,000 feet. Time of indicator disconnection: Maximum of 2
ms after the last byte.
Te communication signals are electrically isolated from the rest of the
instrument, and can be 1200, 2400, 4800, 9600, 19200, 38400, and
57600 bps.
•
Number of data bits: 8, without parity or pair parity
•
Number of stop bits: 1
•
Time to start response transmission: up to 100 ms after
acknowledging the command.
•
Protocol: MODBUS (RTU)
RS485 INTERFACE: ELECTRICAL CONNECTION
The RS-485 signals are:
D1 = D: Bidirectional data line
D0 = D: Inverted bidirectional data line
C = GND: Ground. Optional connection to improve communication
performance
