The addition Expansion Units to Analog I/O Units
(Numerical indicator type) provides these functions.
Local Control (for Analog Input
Units)
You can combine the digital output of the
Expansion Unit with the Comparator function of Analog Input Slave Unit, and have
the ON/OFF control.
Extended Allocation of Digital
Data to I/O Memory
The bits on the connected Expansion Unit can be
allocated together with analog data of the Slave Unit to the I/O memory of the
Master Unit.
Setting the Input Time Constant
(for Input/Output Expansion Units)
You can select a time period to check the on/off
status of inputs to the Expansion Unit. The input values are read several times
in the set time period. The inputs are regarded valid only when all read values
are consistent, i.e., either they are all on or all off.
Holding or Clearing the Outputs at Errors
(for Input/Output Expansion Units,
Output Expansion Units)
You can select holding or clearing the output
values when there is a communications error.
