Product Overview

Remote IO system consists of network adapter module and extended IO module.
The network adapter module controls fieldbus communication and it realizes
communication link with host station controller or host computer software.
The extended IO module controls the connection with the input and output
sensors in the field. At first the Input IO module collects the field signals and sends it
to the network adapter through the internal bus. Secondly the controller reads and
processing data from the adapter through the field bus, and it writes the output data
into the network adapter, then the network adapter could write the output data into the
output IO module via the internal bus, so the the field equipment control could be
realized.
According to the communication interface of the controller system, the network
adapter could select the corresponding bus module and mainstream industrial
communication protocols including Modbus, Profibus-DP, Profinet, EtherCAT,
EtherNet/IP, CANsopen, CC-Link, PowerLink, etc. And there are 6 categories of
extended IO modules such as: digital input module, digital output module, analog
input module, analog output module, special module, hybrid IO module, etc.
The network adapter and the extended IO module could be freely combined
according to the field requirements, and it could achieve lower cost with the Remote

CN-8031 Modbus TCP Network Adapter
1 Module Overview
CN-8031 Modbus TCP Network Adapter supports the standard Modbus TCP
Server Communication, and Ethernet supports the cascade function of dual-port
switches. This adapter supports access to 5 Modbus TCP clients simultaneously,
supports Modbus function code 01/02/03/04/05/06/15/16 /23, supports the Modbus
application of watchdog, supports the process data maximum sum of input and output
of 8192 bytes, and supports number of the extension IO module of 32. Module carries
with the diagnostic function and it can monitor the communication state of IO module
in real time.
