Web-API - HTTP requests / AJAX
The status of inputs, counters and outputs can be queried using HTTP requests. In
addition the outputs can be directly controlled using HTTP requests.
OPC DA / OPC UA
Together with the W&T OPC Server the Web-IO can be accessed from any OPC client
applications.
SNMP
The status of inputs, counters and outputs as well as the configuration and error
status can be obtained via SNMP. For easy integration into SNMP systems, a private
MIB is available which can be downloaded directly from the device.
Modbus-TCP
With Modbus TCP, the Web IO supports one of the most common industrial proto-
cols. Any Modbus-TCP master can access the IOs by reading and writing the corres-
ponding registers.
Individual applications
The Web-IO offers TCP and UDP socket 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.
Actions
Depending on configurable events at the IOs, the Web-IO can initiate actions such
as sending an email message. Other actions include sending syslog messages or
SNMP traps, writing to a file via FTP, sending data via TCP or UDP, or switching its
own outputs.
