Introduction 2
1.3 The VersaMaxTM Family of Products
The VersaMax family of products provides universally distributed I/O that
spans PLC and PC-based architectures. Designed for industrial and
commercial automation, VersaMax I/O provides a common, flexible I/O
structure for local and remote-control applications. The VersaMax PLC
combines big-PLC power with a full range of I/O and option modules.
VersaMax I/O Stations with Network Interface Modules make it possible
to add the flexibility of VersaMax I/O to other types of networks.
VersaMax meets UL, CUL, CE, Class1 Zone 2, and Class I Division 2
requirements.
As a scalable automation solution, VersaMax I/O combines compactness
and modularity for greater ease of use. The 70-mm depth and small
footprint of VersaMax I/O enable easy, convenient mounting as well as
space-saving benefits. Modules can accommodate up to 32 points of I/O
each.
The compact, modular VersaMax products feature DIN-rail mounting
with up to eight I/O and option modules per “rack” and up to 8 racks per
VersaMax PLC or VersaMax I/O Station system. Expansion racks can be
located up to 750 meters from the main VersaMax PLC or VersaMax I/O
Station rack. Expansion racks can include any VersaMax I/O, option, or
communications module.
VersaMax provides automatic addressing that can eliminate traditional
configuration and the need for hand-held devices. Multiple field wiring
termination options provide support for two, three, and four-wire
devices.
For faster equipment repair and shorter Mean-Time-To-Repair, the hot
insertion feature enables the addition and replacement of I/O modules
while a machine or process is running and without affecting field wiring.

1.4 The VersaMax Genius I/O Station
A VersaMax Genius I/O Station consists of a group of VersaMax modules
with a VersaMax Genius NIU and attached power supply in the first
position.
Figure 1: Example of a VersaMax Genius I/O Station
An I/O Station provides up to 64 analog channels and up to 1024 discrete
points for 256 total bytes of I/O. The Genius NIU operates as a device on
a Genius bus, automatically exchanging I/O, diagnostic, and control data
with a PLC or host computer.

Introduction 4
1.4.1 VersaMax I/O in a Genius System
A VersaMax Genius I/O station can be used on the same bus as PLCs with
Genius Bus Controllers, Genius I/O blocks, Field Control I/O stations, and
Remote I/O drop.
Figure 2: Example of a VersaMAX I/O Station in a Genius System
VersaMax I/O stations can be used in redundant bus and redundant CPU
applications. The Genius NIU provides a built-in bus-switching capability.
See Section 6: Redundancy for more information about using the NIU in a
redundancy system.

Introduction 5
1.5 The Genius NIU
The VersaMax Genius Network Interface Unit (IC200GBI001) interfaces a
VersaMax I/O Station to a Genius I/O bus. The system host can be any
PLC or computer capable of controlling the Genius bus.
Figure 3: Genius NIU (Old Rotary on Left/New Rotary on Right)
The Network Interface Unit installs on a 35mm x 7.5mm conductive DIN
rail. A VersaMax power supply module mounts directly on the righthand
side of the NIU. LEDs on the lefthand side indicate the presence of power
and show the operating mode and status of the NIU. Three rotary dials
beneath a clear protective door are used to configure the NIU’s address
on the Genius bus and to set its communications baud rate. Removable
connectors are used to install single or redundant bus cables. These
connectors make it possible to disconnect a bus cable from the NIU
without breaking the continuity of the bus, so other devices on the same
bus can continue operating.

•Series 90™-70 PLC
•Series 90™-30 PLC
For some products, minimum versions are required for use with a Genius
NIU:
•On a Genius bus controlled by an IC697 PLC or PACSystems RX7i:
—IC697 CPU firmware, release 3.0 or later.
—Genius Bus Controller release 5.4 or later. Upgrading the 90-
70
—Genius Bus Controller firmware to version 6.0 (or higher) is
strongly recommended.
•For a Series 90™-30 PLC
—CPU firmware: any version.
—Bus Controller: any version.

1.7 Power Supplies
An AC or DC Power Supply module installs directly on the NIU. The Power
Supply provides +5 V and +3.3 V power to the modules in the station.
Additional power supplies can be installed on special booster carriers if
needed for systems where the number of modules creates the need for a
booster. No booster supply is needed to power conventional I/O
modules.

Introduction 11
1.9 Carriers
Carriers provide mounting, backplane communications, and field wiring
connections for all types of VersaMax modules. I/O modules can be
installed on carriers or removed without disturbing field wiring.
There are three basic I/O Carrier types:
•Terminal-style I/O carriers. Modules mount parallel to the DIN rail.
•Compact Terminal-style I/O Carriers. Modules mount perpendicular
to the DIN rail.
•Connector-style I/O Carriers. Modules mount perpendicular to the
DIN rail. These carriers are normally used with Interposing I/O
Terminals as illustrated below. Other terminal types are also
available.
See the VersaMax Modules, Power Supplies, and Carriers User’s Manual
(GFK-1504) for information about VersaMax I/O Carriers and Terminal
Strips.

1.10 Expansion Modules
Expansion modules can be used to extend the I/O Station and add more
modules.
To use an expansion rack with a Genius NIU that is controlled by a Series
90-30 PLC, the 90-30 CPU must be model CPU366, 367, or 374 (any
version) or 350, 352, 360, 363, 364, or 374, Release 10.0 or later. There are
two basic types of VersaMax I/O expansion systems, Multi-Rack, and Two-
Rack Local:
•Multi-Rack: A VersaMax PLC or NIU I/O Station with an Expansion
Transmitter Module (IC200ETM001) and one to seven expansion
“racks”, each with an Expansion Receiver Module (IC200ERM001 or
IC200ERM002). If all the Expansion Receivers are the Isolated type
(IC200ERM001), the maximum overall cable length is 750 meters. If
the expansion bus includes any non-isolated Expansion Receivers
(IC200ERM002), the maximum overall cable length is 15 meters.

•Two-Rack Local: A PLC or NIU I/O Station connected directly to one
expansion rack with a non-isolated Expansion Receiver Module
(IC200ERM002). Maximum cable length is 1 meter.
