Rockwell Automation Publication 1794-IN067E-EN-P - March 2024
FLEX I/O Very High-speed Counter Module Installation Instructions
Environment and Enclosure
ATTENTION: This equipment is intended for use in a Pollution Degree 2 industrial environment, in overvoltage Category II applications (as defined in EN/
IEC 60664-1), at altitudes up to 2000 m (6562 ft) without derating.
This equipment is not intended for use in residential environments and may not provide adequate protection to radio communication services in such
environments.
This equipment is supplied as open-type equipment for indoor use. It must be mounted within an enclosure that is suitably designed for those specific
environmental conditions that will be present and appropriately designed to prevent personal injury resulting from accessibility to live parts. The
enclosure must have suitable flame-retardant properties to prevent or minimize the spread of flame, complying with a flame spread rating of 5VA or be
approved for the application if nonmetallic. The interior of the enclosure must be accessible only by the use of a tool. Subsequent sections of this
publication may contain more information regarding specific enclosure type ratings that are required to comply with certain product safety
certifications.
In addition to this publication, see:
• Industrial Automation Wiring and Grounding Guidelines, publication 1770-4.1, for more installation requirements.
• NEMA Standard 250 and EN/IEC 60529, as applicable, for explanations of the degrees of protection provided by enclosures.
Prevent Electrostatic Discharge
ATTENTION: This equipment is sensitive to electrostatic discharge, which can cause internal damage and affect normal operation. Follow these
guidelines when you handle this equipment:
• Touch a grounded object to discharge potential static.
• Wear an approved grounding wriststrap.
• Do not touch connectors or pins on component boards.
• Do not touch circuit components inside the equipment.
• Use a static-safe workstation, if available.
• Store the equipment in appropriate static-safe packaging when not in use.
ATTENTION: This product is grounded through the DIN rail to chassis ground. Use zinc-plated chromate-passivated steel DIN rail to assure proper
grounding. The use of other DIN rail materials (for example, aluminum or plastic) that can corrode, oxidize, or are poor conductors, can result in improper
or intermittent grounding. Secure DIN rail to mounting surface approximately every 200 mm (7.8 in.) and use end-anchors appropriately. Be sure to
ground the DIN rail properly. See Industrial Automation Wiring and Grounding Guidelines, Rockwell Automation publication 1770-4.1, for more information.
Overview
The FLEX™ I/O very high-speed counter module performs high speed counting for industrial applications. The module is an intelligent I/O module that interfaces signals with
any Allen-Bradley® programmable controller that has Ethernet capability.

FLEX I/O Very High-speed Counter Module Installation Instructions
Install the Module
Read this for information on how to install the FLEX I/O module, which mounts on a 1794-TB3G or 1794-TB3GS terminal base.
ATTENTION: During mounting of all devices, be sure that all debris (metal chips, wire strands, and so on) are kept from falling into the module. Debris
that falls into the module could cause damage on power-up.
Mount on Terminal Base
1.
2.
3.
4.
5.
Rotate the keyswitch (3) on the terminal base (4) clockwise to position 1 as required for this type of module.
Make sure the Flexbus connector (1) is pushed all the way to the left to connect with the neighboring terminal base or adapter. You cannot install the module
unless the connector is fully extended.
Make sure that the pins on the bottom of the module are straight so that they align properly with the connector in the terminal base.
Position the module (7) with its alignment bar (6) aligned with the groove (5) on the terminal base.
Press firmly and evenly to seat the module in the terminal base unit. The module is seated when the latching mechanism (2) is locked into the module.
Wire the Module
ATTENTION: To reduce susceptibility to noise, power analog modules and digital modules from separate power supplies. Do not exceed a length of
3 m (9.8 ft) for DC power cabling.
ATTENTION: Do not daisy chain power or ground from this terminal base unit to any AC or DC digital module terminal base units.
ATTENTION: Do not wire more than two conductors on any single terminal.
IMPORTANT
We recommend that you use a twisted-pair, individually shielded cable with a maximum length of 300 m (1000 ft).
To connect wiring for 1794-TB3G and 1794-TB3GS terminal bases, see Figure 1 and Table 1 to complete the following:

Configuration Image
When a configuration is sent to the module, it is checked for consistency before being applied. If an error is found, the PE bit is asserted and the module locally retains its
previous configuration. Your user application program should monitor the PE bit.

Interpret the Status Indicators
This module has one red/green power/status indicator (OK), and one yellow indicator for each input and output. The I/O status indicators are multiplexed in 2 groups (A0, B0,
Z0, O0, O1); and (A1, B1, Z1, O2, O3) at a frequency of 488 Hz. If inputs or outputs change at or near that frequency, the indicators vary in brightness.

When an active indicator (yellow) is lighted, a valid signal (active high or active low) is present at the input terminals. The module power/status indicator (OK) shows that
power is applied to the module, and the status of the module.

Description
• Hardware diagnostic error, TF set to 1 and module/channel status contains error code.
• Hardware runtime failure (that is, watchdog timeout), module communication ceases.
• The module is configuring hardware, NR is set to 1.
• The module is in test mode (bits 8…15 of counter control word are nonzero), TF set to 1.

• The module 24V power is below minimum rating.
• The module is active and behaving normally.
• The module is not configured.
• Programming error, PE is set to 1 and the error code is supplied in bits 0…11 of the module/channel
status word.
• Field power fault, FP set to 1.
• Adapter powered down, and module local power still active.
• The ControlNet® cable is disconnected.
• PLC in PROG mode.

Diagnostic Codes Returned by the Module
If an incomplete, incorrect, or conflicting set of configuration parameters is sent to the module, the PE bit is asserted, the green module status indicator flashes, and an
error code is displayed in bits 0…11 of the module/channel status word. The codes are identified in Table 2. Use a CIO instruction to access this information.

Description
A reserved configuration or mode was programmed.
ZF/BF/AF were selected and no filter was programmed, or multiple filters were selected.
A time base was entered that was not a multiple of 10, or the time base is out of range (>3000, that is 3 s).
A configuration that requires a time base was selected and no gate interval was set, or the gate interval is out of range (>3 s)
or the product of time base and gate interval is greater than 3 s.
A rollover of zero was programmed through PWM was not selected; a rollover was programmed and PWM was selected; or the
rollover is out of range (1 < rollover < 16,777,216).
The preset (1 < preset < 16,777,216) is out of range.
A configuration was selected that requires a scalar, and no scalar was programmed or multiple scalars were selected.
A tie has been connected to an unprogrammed window.
Counter 0 window ON and OFF values are equal and not zero or counter 0 window ON and OFF value greater than 16,777,215.
Counter 1 window ON and OFF values are equal and not zero or counter 1 window ON and OFF value greater than 16,777,215.
Reserved
During hardware self-tests, when either Flexbus power or terminal base power is first applied and a fatal error occurs, the TF bit is asserted and the red module/power
status indicator comes on. An error code is placed in the lower byte of the module/channel status word to indicate the failed resource. Use a CIO instruction to access this
information. When using the CIO instruction, this would be word 10.
