FUNCTIONAL DESCRIPTION:

IS220PIOAH1A is an ARCNET Interface I/O Module manufactured and designed by General Electric as part of the Mark VIe Series used in distributed control systems. The ARCNET I/O pack (PIOA) provides an interface for the excitation control. The I/O pack mounts to the JPDV terminal board through a 37-pin connector. The LAN connections are made to the JPDV. System input to the I/O pack is through dual RJ-45 Ethernet connectors and a 3-pin power input. Visual diagnostics are provided through indicator LEDs. Excitation control ARCNET uses a single PIOA in the C core for simplex applications or a single PIOA in R and C cores for redundant applications.

INSTALLATION:

• Securely mount the JPDV terminal board to the front core board holder.

• Plug the PIOA I/O pack into the JA1 terminal board connector for an ARCNET excitation control interface.

• Mechanically secure the I/O pack using the threaded studs adjacent to the Ethernet ports. The studs slide into a mounting bracket specific to the terminal board type. The bracket location should be adjusted so that no right-angle force is applied to the DC-37 pin connector between the pack and the terminal board. The adjustment should only be required once in the life of the product.

• Plug in one or two Ethernet cables depending on the system configuration. The PIOA will operate over either port. If dual connections are used, the standard practice is to connect ENET1 to the network associated with the R controller.

• Apply power to the PIOA by plugging in the connector on the side of the I/O pack. It is not necessary to insert this connector with the power removed from the cable as the I/O pack has inherent soft-start capability that controls the current inrush on the power application.

OPERATION:

• INPUT/OUTPUT SIGNALS: The I/O interface acquisition board (BIOA) has a UART to interface the processor to the RS-485 (no longer used), an ARCNET controller chip to interface the processor to the excitation control DLAN LAN, and a programmed complex programmable logic device (CPLD) to provide the glue logic for the hardware interfaces. The serial communication LEDs (AR, AT, R, T) are on the BIOA board but driven by the processor.

• ID LINE: The processor board and acquisition board within the I/O pack contain electronic ID parts that are read during power initialization. A similar part located with each terminal board DC-37 pin connector allows the processor to confirm the correct matching of the I/O pack to the terminal board and report board revision status to the system level control.

• POWER MANAGEMENT: The I/O pack includes power management in the 28 V input circuit. The management function provides a soft start to control current inrush during power application. After applying power, the circuit provides a fast current limit function to prevent an I/O pack or terminal board failure from propagating back onto the 28 V power system. The green PWR indicator will light when power is present and working properly. If the current limit function operates, the indicator will be out until the problem is cleared.
