IS220PDIOH1A is a Discrete Input/Output Module manufactured and designed by General Electric as part of the Mark VIe Series used in distributed control systems. The electrical link between one or two I/O Ethernet networks and a discrete input/output terminal board is provided by the discrete input/output (PDIO) pack. The pack includes an acquisition board particular to the discrete input/output function and a processor board that is shared by all Mark* VIe distributed I/O packs. The pack can accept up to 24 contact inputs, manage up to 12 relay outputs, and get feedback signals particular to the terminal board.

Functional Description

  • The voltage capability of PDIO is determined by the connected terminal board. Three-pin power input and two RJ45 Ethernet connectors serve as the system input to the battery pack. A DC-62 connector that is directly connected to the corresponding terminal board connector is used for discrete signal input and output. Indicator LEDs are used to display visual diagnostics.
  • In terms of functionality, PDIO is the same as combining a PDIA and PDOA I/O pack into a single unit. It is mounted on a TDBS terminal board for simplex applications, which is an amalgam of an SRLY relay terminal board and an STCI contact input terminal board.
  • It mounts on a TDBT terminal board for TMR applications, which, when combined with the WROB option, provides the functionality of a terminal board combined with a TBCI contact input terminal board. The connections made when three PDIO packs are installed on a TDBT terminal board are shown in the next image.

Compatibility

The discrete contact input/output terminal boards TDBT for TMR PDIO applications and TDBS for single PDIO applications are both compatible with the PDIOH1A. Option cards are accepted in the terminal board's relay output section, as detailed in this document's subsequent sections. The compatibility information is provided in the table below:

IS220PDIOH1A Installation

  • Mount the selected terminal board firmly.
  • Connect the terminal board connectors to the PDIO I/O pack directly.
  • Use the threaded studs next to the Ethernet ports to mechanically fasten the packs. The studs slip into a mounting bracket made for the particular style of the terminal board.
  • A right-angle force should not be applied to the DC-62 pin connector between the pack and the terminal board by moving the bracket's position. Only one adjustment should be necessary during the lifespan of the product.
  • Depending on the setup of the machine, connect either one or two Ethernet wires. Either port will allow the pack to function. When using dual connections, it is customary to link ENET1 to the network connected to the R controller.
  • Connect the connector on the pack's side to a power source to supply electricity to the pack. Because the I/O pack has an inherent soft-start feature that regulates current inrush on power application, it is not essential to turn off the power before plugging the cable in.
  • If necessary, set up the I/O pack using the ToolboxST* program.

IS220PDIOH1A Operation

Each Mark VIe Ethernet I/O pack or module shares a processing board. It has the following in it:

  • A fast CPU with flash memory and RAM.
  • Two 10/100 Ethernet ports that are connectorized and completely independent.
  • A hardware reset circuit and watchdog timer.
  • A temperature sensor inside.
  • LEDs that display status.
  • The capacity to read IDs on other boards through electronic means.
  • An input power connector with a current limiter and a soft start.
  • Local power supplies, with monitoring and sequencing.

The I/O pack or module function-specific acquisition board is connected to the processor board. The soft-start circuit ramps up the voltage available on the processor board when input power is applied. The processor reset is turned off and the local power supply is turned on in order. After finishing self-test routines, the processor loads application code from flash memory that is particular to the I/O pack or module type. To verify that the application code, acquisition board, and terminal board are correctly matched, the application code reads the board ID information.

When there is a good match, the processor makes an effort to start Ethernet connections by asking for a network address. The dynamic host configuration protocol (DHCP), which is the industry standard, and the terminal board's unique identifier are both used in the address request. Following Ethernet startup, the CPU runs the application, programs the onboard logic, and permits the acquisition board to start working.
