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 PM16DI 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 PM16DO module will automatically read the information
from the PM16DI 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.
