Modbus Enabled
WebRelay-10 can support Modbus/TCP. Modbus is a messaging structure protocol used in
industrial manufacturing control and automation. It is an open protocol and offers interoperability
with software and devices from other manufacturers. This is enabled by selecting Yes in this field.
The default setting for this field is No. (See 3.4 Modbus Operation for more information on using
WebRelay-10 on a Modbus network.)
Note: Modbus communications are disabled whenever the Control Password is enabled.
Modbus Port
This specifies the port used for Modbus/TCP communications with WebRelay-10. By default this is
set to port 502 which is the standard Modbus port. It can be set within the range of 0 to 65535.
Remote Services Enabled
This option enables or disables Remote Services. If Yes is selected, Remote Services will be
enabled as soon as the submit button is pressed and WebRelay-10 will immediately attempt to
make a connection with the remote server (power cycle not required). Once a connection is
established, the connection will remain until it is disconnected by the remote server. Proper
connection with the remote server can be verified by viewing the system status log file (see
Appendix D: Log Files). The default setting for this field is No. Most users should leave this setting
at its default. (See Remote Services at the end of this section for more information.)
