capability is required. The outputs are isolated from the logic and
they share a common negative terminal.
The module may be used as either a slave or master on the Modbus
network. When used with a PC or PLC the module will be configured
as a slave. When used with a MM8DI module in a point-to-point
configuration, the DIP switch 9 must be turned on to set the module
up as a master. In this mode the
MM8DO module will automatically read the information from the
MM8DI module and write the input status to the outputs.
When used as a slave module, 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.
