140NOA61110C Schneider Relay Module
140NOA61110C is a module developed by Schneider Electric for
industrial automation systems. It is typically used as a fieldbus
or network communication module, supporting data exchange with
distributed I/O devices or other third-party products. It is
suitable for master/slave topologies and may have interfaces
compatible with INTERBUS or similar fieldbus protocols, enabling
data transmission of distributed sensors and actuator devices. It
can be used in conjunction with Quantum series master stations to
control slave devices and ensure network openness. Its design meets
the reliability and stability requirements of industrial
environments
Technical specifcations for 140NOA61110C
Product type and protocol: INTERBUS host module, supporting the
INTERBUS fieldbus protocol, used for communication with distributed
sensor and actuator devices in master/slave topologies.
The maximum number of input/output points that can be processed is
4096, which can be distributed across 512 slave devices on the
fieldbus.
The data transmission rate of INTERBUS is 500 kilobits per second,
and the data is transmitted to the Quantum CPU for logical
processing in each scanning cycle.
The bus module supports up to 3 INTERBUS bus modules in the local
Quantum motherboard.
The transmission distance uses remote bus technology, and the total
transmission distance of data between all 512 devices reaches 12.8
kilometers (8 miles).
The communication mode and voltage level communicate in full duplex
mode, and the voltage level on the Quantum remote bus is RS-485.
Multiple LED indicator lights are equipped to display the module's
readiness status, communication status with Quantum CPU, INTERBUS
function status, bus segment operation status, processor fault
status, remote bus fault status, peripheral bus fault status, node
fault status, etc.
Driver and instruction support require a loadable driver ULEX that
provides 256 input data registers and 256 output data registers for
each logical scan. A ULEX instruction can support up to 3
140NOA61110C modules. In addition, PCP communication is also
supported, using two 984 ladder logic loadable instructions, ICNT
and ICOM, to establish a connection to the slave device and
complete communication.
Compatibility and software support: The Quantum INTERBUS main
module can achieve comprehensive functionality with the help of
multiple software packages, compatible with products compatible
with INTERBUS provided by over 300 industrial suppliers, ensuring
network openness, low cost, and wide application.
