Installation and Setup Guidance
Proper installation ensures optimal performance of the 1784-PCIDS. Follow these steps:
-
Power Down: Shut down the host computer and disconnect it from power before opening the chassis.
-
Ground Yourself: Use anti-static wrist straps and work on a grounded table to prevent electrostatic discharge.
-
Handle with Care: The card has an open enclosure with exposed circuitry. Touch only the corners or edges when handling.
-
Insert into PCI Slot: Align the card with an available PCI rev. 2.1 slot and press firmly until it seats correctly.
-
Connect DeviceNet: Attach the DeviceNet cable to the terminal on the card. Ensure proper termination and network power.
-
Power On and Verify: Boot the computer and check the status indicators. The I/O and Network LEDs should light appropriately.
Maintenance and Reliability
Routine maintenance of the 1784-PCIDS is minimal but important. Keep the card free of dust and moisture. The operating temperature range of 32 to 131°F and humidity tolerance of 5 to 95% allow for use in most industrial environments. Periodically inspect the card for signs of wear, such as loose connections or damaged components. Because the enclosure is open, avoid touching the circuitry during operation. Following these practices extends the life of the card and ensures consistent performance.
Compatibility and Integration
The 1784-PCIDS is designed for PLC-5 systems from Allen-Bradley. It works with software like RSLinx and RSNetworx for DeviceNet (Series B) or I/O Linx and RSNetworx (Series A). The card is PCI rev. 2.1 compliant, making it compatible with a wide range of industrial PCs. It requires 5 VDC at 625 mA from the host bus, and 2 MB of free disk space for software installation. Before purchasing, verify that your system meets these requirements.
Selection Guide and Purchasing Advice
When selecting the Allen-Bradley 1784-PCIDS, consider the series (A or B) that matches your software environment. Ensure your PC has an available PCI slot and meets the power and disk space requirements. For a reliable source, PLC Source PRO offers genuine parts and fast shipping.
