 This
module has 16 open collector (NPN) digital outputs. The outputs may be used to
drive lamps or external relays when more drive capability is required. The
outputs are isolated from the logic and they share a common negative terminal.
The outputs
are written to by the Modbus master device such as a PC or PLC. Each output can
be individually switched on or off, or all outputs can be set up at the same
time by writing a single number to the output register which represents the
status of all outputs.
An output
watchdog timer can be configured to switch off all the outputs if there has been
no communications with the module for up to 255 seconds. A value of 0 seconds
will disable this timer and the outputs will remain in the last programmed
state.
Each MMTCP16DO
Module has a unique Ethernet IP address which must be programmed into the PC or
PLC. The IP address in the MMTCP16DO Module is configured via the Web Server.
Any standard Web browser such as Internet Explorer can be used to access the web
pages were configuration is carried out. The converters are factory programmed
with a default IP address of 169.254.111.111. This address must be changed
before the converter is added to an existing network.

The Web page
address "169.254.111.111/ip.htm" is entered into the address
line of the browser window to access the configuration page. This page allows
you to change the IP address of the MOD-MUX TCP Module and to enter a Module
Description Name and Output Names for identification/maintenance purposes.
| IP
Address: The new IP
address can be entered into the web page as shown above. After this has been
done, you must click the Submit button to send the values to the MOD-MUX TCP
Module. The screen will now be updated and if successful will continue to
display the new IP address. The new IP address will only be effective after
the MOD-MUX TCP Module power has been switched off and on again. This
feature allows you to check that the correct IP address has been entered
before being activated. If the IP address has been entered incorrectly and
the power has not been switched off, it is possible to re-enter the correct
IP address. If the power has been switched off and back on again, the
MOD-MUX TCP Module will not communicate until you enter the new IP address
into the address line of the browser window.

| Module
Name: This field
allows you to enter a module description name into the MOD-MUX TCP Module.
This is an identifier for diagnostic/maintenance purposes and is chosen to
best describe the MOD-MUX TCP Module in the system by name or number.

| Output
Names: These fields
allow you to enter an output description name into the MOD-MUX TCP Module.
This is an identifier for diagnostic/maintenance purposes and is chosen to
best describe the particular output by name or number.
