Product Introduction
REST
REST (Representational State Transfer) is another Web-based
protocol that can be used to integrate the Web-IO into the
environment of Industry 4.0 and the Internet of Things.
Web-API - HTTP-Requests/AJAX
The status of Input, Counter and Output can be queried
using HTTP requests. In addition the outputs can be directly
controlled using HTTP requests.
OPC
Together with the W&T OPC Server the Web-IO can be accessed
from any OPC client applications.
SNMP
The status of Input, Counter and Output as well as the config
-
uration and error status can be obtained via SNMP. A private
MIB for direct download from the device is available for easy
incorporation into SNMP systems.
Modbus-TCP
With Modbus-TCP the Web-IO supports one of the most
common industry protocols. By reading and writing the corre-
sponding registers any Modbus-TCP master can access the IOs.
In-house applications
The Web-IO offers TCP and UDP socket accesses for access
from your own applications. In both cases the Web-IO supports
addressing using command strings, but also by exchanging
binary structures.
With the support of HTTP requests your own Web applications
(e.g. with PHP or JavaScript) can also access the Web-IO.
