The NETWORK I/O MODULE is a small yet very powerful unit that
provides a remote I/O interface for a central control system.
It has totally configurable digital I/O that will allow its use in a wide
variety of applications. It is totally controlled from either its internal RS232 or
Ethernet port.
Numerous modules can be used in a system to provide
monitoring and control on a large number of different units. Since each module
set has its own IP address, the only practical limits on the system size is the
network to which they are attached. Also,
since each module operates independently, there is no reduction in data
collection performance as the system grows.
The system has both master and slave modules.
Slave modules may be connected to the master via the RS485 port. The user
has no additional communications interface requirements when using slaves.
The master module will handle all I/O with the slave(s) and present all
information via the single RS232 or Ethernet port.
Control of the outputs on the slaves is handled in the same manner.
The user just talks to the master and it handles the slave(s).
The I/O is brought out on
DB25 connectors. All
I/Os may be configured as either inputs or outputs.
Any or all of them may be set as optically isolated inputs.
Any or all may be configured as outputs. Half may be configured as
optically isolated transistor outputs. Half may be configured as relay outputs.
These configuration patterns allow the user to apply the unit in an almost
endless variety of applications.
There
may be up to 7 slave units tied to the master via the RS485 slave link to allow
a maximum of 512 I/0 points to be tied to one Ethernet port.
The DB25 connector wiring is fully compatible with SEMI
E84-0701. When configured for this
application the relays are disabled and the optical isolated inputs and outputs
provide an interface suitable for both the Hardwired Connection and Optical
Transmission Device connection (as called out in Figures 23 and 24 of the
standard).
The
unit also has the ability to run interactive local programs.
These operational sequences are held in the internal flash memory and may
be activated by a simple configuration command.

1.) Each I/O point may be
individually configured as either an input or output--8 are configurable as
Relay outputs and 8 as OCT outputs.
