Problems Resolved for Release 3.20
The IC200GBI001-HL replaces IC200GBI001-GK and previous
versions of the hardware and firmware.
Hardware version IC200GBI001-Gx and later hardware versions
can be upgraded in the field to firmware revision 3.20 and used in
safety-certified applications.
Version 3.20 firmware may be downloaded to any hardware
revision of the Genius NIU. However, -Fx and earlier hardware
versions do not include the external windowed watchdog timer
circuit. Thus, versions Fx and earlier are not certified for use in the
safety-relevant portion of a GMR system.
IC200GBI001 modules with firmware version 3.10 or earlier
versions may report unexpected and highly intermittent Loss of I/O
Module faults for the VersaMax analog input modules
IC200ALG240, IC200ALG620 and IC200ALG630; the analog
output module, IC200ALG331; the Mixed Discrete / High-Speed
Counter Module, IC200MDD841; and the Serial Communications
module, IC200CMM020. These faults never occur for most users.
This issue has been corrected in IC200GBI001 firmware
version 3.20.
For users who want newer GNIU firmware, a firmware upgrade kit
is available for download at Firmware
upgrades require a PC to NIU serial cable, IC200CBL002.
VersaMax analog input modules IC200ALG240, IC200ALG620 and

Restrictions and Open Issues
▪ When a store of a new configuration is interrupted (for example, by
Firmware version 2.30
removal of the serial cable), the Genius NIU generally reverts
operation to match the previous configuration. However, if the
interruption occurs during a certain 2-second window, the Genius
NIU does not restore Enhanced Diagnostics operation. The EDM

If an intelligent I/O module (ALG240, ALG320, ALG620, ALG630,
MDL841) or a Network Communications Module is present in the
Genius NIU station, and the GNIU is commanded to clear its
configuration, the before-mentioned module is not included in the
subsequent auto-configuration, nor are any modules that are
located to the right of that module. This is not an issue when storing
hardware configuration; It is only an issue for the clear configuration
operation. If you have one of these modules present, and need to
generate an auto-configuration using this method, cycle power of
the GNIU after the clear configuration command completes.

Addition of Device fault. For the case of a GMR PLC, an operator
must issue a GMR I/O Reset command (%M12258) to recover the
use of those input channels.
Operating Notes/Restrictions: Enhanced
Diagnostics Mode
Hot Removal and Hot Insertion of the VersaMax GNIU is not
permitted. Attempting to hot insert or hot remove the GNIU may
interfere with backplane transfers between the GNIU and other
modules in the station, and can cause the GNIU’s diagnostic tests
to declare an error. That can cause other modules in the station to
be marked as faulted, and may also cause the entire input station to
go offline. For cases where a VersaMax GNIU needs to be
replaced, the system’s operating procedures must require the
operator to remove power from the GNIU before attempting the
Powering down the entire VersaMax station will cause the system
to temporarily lose all analog channels (up to 60) in that station, not
just the channels associated with the module that is being replaced.
If a redundant VersaMax Input Station is available, the procedures
may optionally allow the overall system to continue to operate with
a degraded level of input channel redundancy for a short time while
the faulted input station is being repaired.
When used in the safety-relevant portion of a GMR system, the GNIU’s
Enhanced Diagnostics Mode must be enabled. Select whether to
enable or disable Enhanced Diagnostics Mode via a hardware
configuration option for the GNIU. The default is disabled. When
Enhanced Diagnostics Mode is enabled, the following requirements
must be met. (Note: More information about Enhanced Diagnostics
Mode is available in the Genius NIU User’s Manual.)
System Requirements
The only modules allowed in the rack are the Power Supply, the
GNIU, and up to four total ALG265 / ALG266 modules (any
combination of ALG265 and ALG266 modules is allowed).
All of the analog modules must be located in the main rack.
Expansion racks are not allowed.
Empty IO carriers are not allowed.
Configuration Requirements
Operating Notes: General
The GNIU's Report Faults parameter must be set to Enabled. In
addition, the Report Faults parameter on every analog module
must be set to Enabled.
The GNIU’s CPU Redundancy parameter must be set to GMR.
The GNIU’s “BSM Present” and “BSM Controller” parameters must
be set to No.
When performing a firmware upgrade on an intelligent I/O module
in the Genius NIU station, the host controller must be put into Stop
mode, or the Genius network cable must be removed from the NIU.
Most Genius NIU faults will appear in the I/O fault table of the I/O
controller. However, some Genius NIU faults (such as Loss of rack
and System configuration mismatch) appear in the controller’s PLC
fault table. The Genius NIU re-reports unresolved faults when the
controller’s I/O fault table is cleared. It does not re-report
unresolved PLC faults when the PLC fault table is cleared.
4. For each module except the last, one analog input channel becomes
unusable. These unused channels still count towards the number
of %AI channels that the GNIU will send to the Genius Bus
When clearing faults, clear both the PLC and I/O fault tables in that
order. Then view both the I/O and PLC fault tables to ascertain the
Genius NIU station’s status.
Operating Requirements
1. Avoid situations where all of the following are true at the same time:
- the GNIU's Enhanced Diagnostics Mode is set to Enabled
The power supply mounted on a Genius NIU and any booster
power supplies that are used in the same rack should be powered
on and off together.
There is no response from the Genius NIU to a Write Configuration
Datagram COMMREQ. The application program must issue a
Read Configuration Datagram to determine the effectiveness of a
previous Write Configuration Datagram.
If the Genius NIU is configured using datagrams (for example, by
issuing a COMMREQ to a Genius Bus Controller), the value of the
Force BSM bit is accessible but must not be changed.
If the Genius NIU's CPU Redundancy parameter is set to "Duplex",
analog output and intelligent modules must not be used in the I/O
Intelligent I/O modules (IC200ALG240, ALG331, ALG620, ALG630,
and MDD841) should not be used in an extended distance
expansion system. If a rack with an intelligent I/O module in an
extended distance expansion system is power cycled, or if a single
slot Genius configuration datagram is sent to an intelligent module
in an extended distance expansion rack, the other expansion racks
and the other devices on the Genius network may default their
outputs briefly.
- the GNIU is online with a Genius Bus Controller.
- serial communications (programmer operations: download remote
I/O configuration, verify equality, clear configuration; or Winloader)
are taking place.
Disconnect the GNIU from the Genius bus before attempting any
serial communications if a hardware configuration with Enhanced
Diagnostics Mode set to Enabled either is currently installed or will
be installed in the GNIU.
After completing serial communications disconnect the serial cable
from the GNIU’s expansion port. The GNIU can then be reattached
to the Genius bus.
An alternative to disconnecting the GNIU from the Genius bus is to
power off or disconnect all of the Genius Bus Controllers on the bus.
2. Forcing an I/O point on the GNIU is not permitted.
3. In Enhanced Diagnostics mode, the GNIU continually runs extensive
diagnostic tests in the background during normal operation. These
diagnostics cause the GNIU to be more sensitive to disturbances
on the Genius bus. When a Genius bus disturbance or
spontaneous hardware failure causes a diagnostic test to declare
an error, the GNIU stops communicating on the Genius bus and
attempts to reset itself. The loss of communications causes the
host PLC(s) to log a Loss of Device fault and default the affected
inputs (according to the host’s configuration). GMR PLCs will
disregard the channels associated with that GNIU. If the GNIU is
able to revive itself, it tries to resume normal operation several
seconds later. If this is successful, the host PLC(s) will log an

When configuring a Genius NIU in the bus configuration for a
Genius Bus Controller, the data lengths specified for %I, %Q, %AI
and %AQ data must match the hardware configuration of the NIU.
If the I/O data lengths of the Bus Controller and NIU do not match,
the NIU will not join the bus and will not report the System
configuration mismatch fault caused by the mismatch.)
Quick Start Guide
Preinstallation Check
Carefully inspect all shipping containers for damage. If any equipment is
damaged, notify the delivery service immediately. Save the damaged
shipping container for inspection by the delivery service. After unpacking
the equipment, record all serial numbers. Save the shipping containers
and packing material in case it is necessary to transport or ship any part
of the system.
The correct I/O data lengths can be determined by examining the
hardware configuration for the Genius NIU. The procedure
described here is for Machine Edition Logic Developer – PLC
programming software.
If the Genius NIU hardware configuration is available:
Open the project that includes the Genius NIU target and
select the NIU target.
Under the NIU target, right-click on Hardware
Configuration and select “Hardware Reference View”.
For each I/O data tab (%I, etc.), use the largest address
in the “End” column as the data size for that I/O data
type. If there are no entries for a data type, the data
length for that type is zero.
The DIN rail must have a conductive
(unpainted) finish for proper
(Refer to the heading Module Installation for information about
space requirements or module orientation, or if you are installing
the NIU in an area of excessive vibration).
Connect the Windows PC running the programming
software to the Genius NIU using a VersaMax NIU serial
cable, IC200CBL002.
Create a new project for a GE Fanuc PLC. Within the
new project, create a new Genius NIU target.
Upload the hardware configuration from the Genius NIU to
the target.
Under the NIU target, right-click on Hardware
Configuration and select “Hardware Reference View”.
For each I/O data tab (%I, etc.), use the largest address in
the “End” column as the data size for that I/O data type. If
there are no entries for a data type, the data length for
that type is zero.
Install the NIU on the DIN Rail by simply clicking it into place.
Note: The NIU and connecting carriers
must be installed on the same section
of 35mm x 7.5mm DIN rail.
If the Genius NIU hardware configuration is NOT available:
Install the Power Supply on the NIU.
The latch on the power supply must be
in the unlocked position.
Align the connectors and the latch post
and press the power supply module
down until the two tabs on the bottom of
the power supply click into place.
Turn the latch to the locked position to
secure the power supply to the top of
the NIU.
If the GNIU attempts to come online with a configuration that has
I/O types and lengths that do not match those expected by the
controller, a System Configuration Mismatch fault for the GNIU will
appear in the controller's PLC fault table: This fault is generated by
the controller itself. Additional faults present in the GNIU do not
appear until the mismatch in I/O types and lengths is corrected.
Complete the power supply wiring as described in the installation
instructions provided with the Power Supply.
Adjust the rotary switches on the front of the NIU using a 2.44mm
(3/32in) flat screwdriver.
10. When the host controller is in STOP mode and the GNIU is
configured for dual bus operation, a power cycle to the GNIU
switches the bus from BUS A to BUS B immediately. The GNIU
does not switch back from BUS B to BUS A even if the host
controller goes to RUN mode.
Documentation Update
In the VersaMax I/O Modules and Carriers Manual, GFK-1504K:
The note on page 2-38 should have the addition “Carriers cannot be
plugged together or unplugged with power applied”.
The descriptions of the operation of jumpers should have the
addition “Jumper positions cannot be modified with power applied”.

Select the serial bus address with the two upper rotary
switches, SBA X10 (for the tens digit) and SBA X1 (for the
ones digit). Each device on a bus must have a unique serial
bus address in the range 0 - 31.
Select the baud rate to match that used by the other devices
on the bus by setting the bottom rotary switch: (3) 153.6
Kbaud extended, (2) 153.6 Kbaud standard, (1) 76.8 Kbaud,
or (0) 38.4 Kbaud.
Cycle power to the NIU after changing the switch settings.

General Module Installation Instructions
Connect the communications bus to the NIU. (Refer to the
heading Bus Installation Guidelines if the NIU is at the end of
the bus, or for detailed bus installation instructions.)
Main Bus
Modules may be mounted on a
horizontal or vertical DIN rail. When
mounted on a vertical DIN rail, the NIU
must be located at the bottom.
The NIU has two sets of bus
terminals. The upper terminals
are for the main bus cable. The
lower bus terminals are for an
optional redundant (dual) bus
Allow sufficient finger clearance for
opening NIU door.
2. Allow adequate clearance for
serial port cables.
3. Allow adequate space for power
The NIU with power supply attached fits
into a 70mm deep enclosure.
Remove the connector cover on the right-hand side of the
NIU. Do not discard this cover; you will need to install it on the
last carrier. It protects the connector pins from damage and ESD
during handling and use. Do not remove the connector cover on
the left-hand side.

Installation in Hazardous Locations
Connector Cover
Rated thermal specifications are based
on a clearance of 5.1cm (2in) above
and below the equipment and 2.54cm
(1in) to the left of the NIU module.
With power off, install additional modules by mounting
modules on their carriers and sliding them along the DIN rail to
fully engage the connectors in the sides of the carriers.
This equipment is suitable for use in CLASS I, DIVISION 2,
GROUPS A, B, C, D or non-hazardous locations only.
WARNING - EXPLOSION HAZARD - substitution of
components may impair suitability for CLASS I, DIVISION
WARNING - EXPLOSION HAZARD - when in hazardous
locations, turn off power before replacing or wiring modules;
WARNING - EXPLOSION HAZARD - Do not connect or
disconnect equipment unless power has been switched off
or the area is known to be non-hazardous.
For best stability, the DIN rail should be installed on a panel using
screws spaced approximately 5.24cm (6in) apart.
If excessive vibration is a factor the NIU should also be screwed down to
the mounting panel.
Note: Tolerances are +/- 0.13mm (0.005in) non-cumulative.
Note: 1.1-1.4Nm (10-12 in/lbs) of torque should be applied to M3.5 (#632) steel screw threaded into material containing internal threads and
having a minimum thickness of 2.4mm (0.093in).
Power up the NIU. The modules in the I/O station will
automatically be configured, starting at slot 1 in each rack including
expansion racks. If an empty slot or faulted module is encountered,
autoconfiguration for that rack stops. Autoconfiguration then skips
to the next rack and continues until all racks are configured.

Bus Installation Guidelines
The maximum exposed length of unshielded wires should be 5cm (2in).
For added protection, each shield drain wire should be insulated with
spaghetti tubing to prevent the Shield In and Shield Out wires from
touching each other, or the signal wires.
Connect Serial 1 to the Serial 1 terminals of the previous device
and the next device.
Connect Serial 2 to the Serial 2 terminals of the previous device
and the next device.
Connect Shield In to Shield Out of the preceding device. Connect
Shield Out to Shield In of the next device. If the NIU is the first
device on a bus, Shield In can be left unconnected. If it is the last
device on a bus, Shield Out can be left unconnected.
When inserting two wires into the same terminal block position, the
wire size must be 0.86mm2 (18AWG) or smaller. Both wires should
be of the same size and style. Do not mix stranded with solid wire
in the same position.

If either bus will terminate at the NIU, connect a 75, 100, 120, or 150ohm terminating resistor across the Serial 1 and Serial 2 terminals. The
use of a ferrule is recommended to crimp each resistor lead to the
corresponding serial line. If ferrules are not used, twist each resistor lead
with the corresponding serial line and solder them together before
inserting the wires into the terminal block.
System Bus Installation Guidelines
The serial bus can be treated as a Class 2 circuit when appropriate
wiring practices are followed. Maximum bus lengths may be affected
when installation requires the high-voltage rated CM rating. CM types
can replace CL2, but not vice versa.
Do not mix cables of different impedance, regardless of cable run length.
Do not mix cable types in long and/or noisy installations. Other, smallsize twisted pair shielded wire of unspecified impedance can be used for
short runs of 50 feet or less, using 75 ohm terminations. Selection of
wire type may be limited by local and national codes and industry
standards. Consult the cable manufacturer to determine the cable's
suitability for a particular type of installation.
Installing Suppression at the Communications Line
(bus cable
not shown)
For an individual NIU, suppression can
be supplied by connecting two small
MOVs from Serial 1 and Serial 2 to the
Shield Out terminal. Suitable MOVs
include Harris part number V220MA2A,
Panasonic ERZ-CO5FK221U, and
Siemens 505K140. Higher energyrated devices can also be used. Follow
the wiring instructions above for
installing MOVs. Be sure the MOV
leads do not cause shorts between the
serial data and shield connectors.
