FUNCTIONAL DESCRIPTION:

IS220PSCAH1BC is a Serial Communication I/O Module manufactured and designed by General Electric as part of the Mark VIe Series used in distributed control systems. The Serial Communication I/O pack serves as the interface between one or two I/O Ethernet networks and a serial communications terminal board. It includes a BPPC processor board, which is standard across all Mark VIe distributed I/O packs and a serial communications board. The communications board features six serial transceiver channels that can be individually configured for RS-232, RS-422, or RS-485 half-duplex standards. The I/O pack has dual RJ-45 Ethernet connectors for input and 3-pin power input, while its output is via a DC-62 pin connector that links directly to the terminal board. One Ethernet port can also support Ethernet Modbus communication on Simplex networks. LED indicators provide visual diagnostics, and the pack's BPPC processor is compatible with ControlST version V04.07 and higher.

INSTALLATION:

• Directly connect the PSCA I/O pack to the SSCA terminal board connector and secure it using the threaded inserts near the Ethernet ports. These inserts attach to a mounting bracket designed for the specific terminal board type.
• Adjust the bracket position to avoid applying any right-angle force on the DC-62 pin connector between the I/O pack and the terminal board. This adjustment is generally needed only once during the product's lifetime.
• Connect one or two Ethernet cables depending on your system setup. The I/O pack functions with either port.
• If using dual Ethernet connections, it's common to connect ENET1 to the network with the R controller, although the PSCA can operate correctly on either port.
• Power the I/O pack by plugging in the connector on its side. There's no need to disconnect the power beforehand, as the I/O pack’s soft-start feature controls current inrush when power is applied.
• In the ToolboxST application, add the PSCA module and configure the required devices. For help, open the Component Editor and press F1.

DATAFLOW FROM PSCA TO CONTROLLER:

• Dataflow from the PSCA to the Mark VIe controller is of two types: fixed I/O and Modbus I/O. Fixed I/O is associated with the smart pressure transducers and the Kollmorgen electric drive data.
• This data is completely processed every frame, the same as conventional I/O. These signals are mapped into signal space, have individual health bits, and have offset/gain scaling.
• Several of these signals are configured to support system limit checking. Modbus: Modbus I/O is the I/O associated with the Modbus ports.
• Because of the quantity of these signals, they are not completely processed in every frame; instead, they are packaged and transferred to the Mark VIe controller, over the IONet through a special service.
• This can accommodate up to 2400 bytes, at 4 Hz, or 9600 bytes at 1 Hz, or combinations thereof. This I/O is known as second-class I/O, where coherency is at the signal level only, not at the device or board level.
• Health bits are assigned to individual points in the same fashion as the other protocols, and system limit checking is not performed. Three consecutive time-outs are required before a signal is declared unhealthy.
• Diagnostic messages are used to annunciate all communication problems. The input value is cleared for a given signal after four consecutive time-outs occur on that signal.

FREQUENTLY ASKED QUESTIONS:

What is a Serial Communication I/O module?

A Serial Communication I/O module is a device that facilitates serial communication between a computer or controller and external devices. It typically provides serial ports (such as RS-232, RS-485, or UART) for data transmission.

What are the common applications of Serial Communication I/O modules?

Serial Communication I/O modules are used in various applications, including industrial automation, data acquisition, embedded systems, robotics, and IoT (Internet of Things) devices. They enable connectivity with sensors, actuators, displays, and other peripherals.

What types of serial interfaces do these modules support?

Serial Communication I/O modules commonly support RS-232, RS-485, UART (Universal Asynchronous Receiver-Transmitter), SPI (Serial Peripheral Interface), and I2C (Inter-Integrated Circuit) interfaces. The specific interface types vary depending on the module.
