Overview Manuals Specifications Application Certifications Hardware Compatibility

Features:

  • Compliant with PCI revision 2.2, supporting 5V and 3.3V signaling, 32-bit and 64-bit slots, and PCI-X slots (but not PCI Express).
  • Provides drivers for Windows XP (SP1+), Windows 2000 (SP4+), Windows 98, and Windows Me with RSLinx 2.42.00+.
  • Operates from 0 to 55 °C, withstands 2g vibration, 30g operating shock, 6kV ESD contact discharge, and 10V/m radiated RF immunity.
The 1784-PCIC eliminates installation guesswork by working with both 5V and 3.3V PCI slots, as well as 32-bit and 64-bit slots, plus PCI-X slots. However, the 1784-PCIC explicitly warns against PCI Express slots, preventing costly installation errors and hardware damage.

The 1784-PCIC allows older factory PCs running Windows 98, Me, 2000, or XP to connect to modern ControlNet networks. By requiring only RSLinx 2.42.00+, the 1784-PCIC protects capital investment in legacy control systems without forcing expensive OS upgrades.

The 1784-PCIC survives harsh factory conditions with an operating temperature range of 0 to 55 °C and 5-95% noncondensing humidity. It tolerates 2g vibration and 30g shocks, plus 6kV ESD and 10V/m RF immunity, ensuring reliable ControlNet communication in electrically noisy environments.

The 1784-PCIC Allen-Bradley Communication Interface Card may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

  • Manufacturing Execution System (MES): Bridges ControlNet data at the production line level directly to enterprise-level management systems.
  • Electromagnetic Compatibility (EMC): Complies with CE marking requirements and supports EN 50081-2 (xIndustrial Emissions) and EN 50082-2 (Industrial Immunity) standards.
  • Safety Certifications: UL certified (USA) and CSA certified (Canada).
  • Environmental Standards: Complies with C-Tick (RCM) certification for the Australian and New Zealand markets.
  • Slot Support: Supports standard 5V PCI slots.
  • Redundancy Support: Features dual BNC interfaces, fully supporting ControlNet media redundancy.
  • Operating Systems: Primarily supports Windows 2000, XP, and Windows 7 (specific driver versions required). Note: In modern systems such as Windows 10/11, due to driver limitations, a USB version of the 1784-U2CN is typically required as an alternative.
  • Network Connectivity:Can communicate with any ControlNet device (such as 1756-CN2R, 1794-ACNR, 1734-ACNR) for point-to-point or multipoint communication.
Description
The 1784-PCIC communication interface card connects a SoftLogix controller directly to the ControlNet network. It complies with PCI revision 2.2 and fits universal PCI slots including 5V and 3.3V, 32-bit and 64-bit, as well as PCI-X slots. However, the 1784-PCIC is not compatible with PCI Express and must never be inserted into a PCI Express slot.

Installing the 1784-PCIC requires specific steps depending on your operating system. Driver installation procedures are provided for Windows XP, Windows 2000, Windows 98, and Windows Me. For Windows XP, you must install the 1784-PCIC driver for the first time or update an existing driver using the documented steps. The Virtual Backplane Driver is also required for certain configurations.

The 1784-PCIC operates within strict environmental limits. Its operational temperature ranges from 0 to 55 °C (32 to 131 °F), while storage temperature spans -40 to 85 °C (-40 to 185 °F). Relative humidity can be 5 to 95% noncondensing. The 1784-PCIC also withstands 2g vibration at 10-500Hz and 30g operating shock, ensuring reliability in industrial computer environments.

To use the 1784-PCIC, you must have Rockwell Software RSLinx version 2.42.00 or later. The card also features status indicator LEDs for diagnostics. Once configured, the 1784-PCIC allows you to configure ControlNet communications drivers within RSLinx, enabling seamless connection between a SoftLogix controller and devices on the ControlNet network.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Can I install the 1784-PCIC into a modern computer with PCI Express slots?
No. The 1784-PCIC is explicitly not compatible with PCI Express and should never be inserted into a PCI Express slot. It requires standard PCI, PCI-X, or 32/64-bit PCI slots compliant with revision 2.2.
Does the 1784-PCIC work on Windows 10 or Windows 11?
No. The 1784-PCIC only provides drivers for Windows XP (SP1+), Windows 2000 (SP4+), Windows 98, and Windows Me. You will need an older PC or a different ControlNet interface for modern operating systems.
My factory computer runs very hot. Will the 1784-PCIC survive?
The 1784-PCIC operates reliably from 0 to 55 °C (32 to 131 °F) inside the PCI slot. If your chassis exceeds 55 °C, add cooling. Storage range is -40 to 85 °C, and humidity can be 5-95% noncondensing.
What Rockwell software is required for the 1784-PCIC?
You must have Rockwell Software RSLinx version 2.42.00 or later. After installing the 1784-PCIC driver, use RSLinx to configure the ControlNet communications driver and connect your SoftLogix controller to the ControlNet network.
