Product Introduction
The Serial Communication (IS420PSCAH1B) I/O pack provides the electrical interface between one or two I/O Ethernet networks and a serial communications terminal board.The I/O pack contains a BPPC processor board common to all Mark VIe distributed I/O packs and a serial communications board. The communications board contains six serial transceiver channels, each of which can be individually configured to comply with RS-232, RS-422, or RS-485 half-duplex standards.

Product Details
The IS420PSCAH1B I/O pack contains a functionally compatible BPPC that is supported in ControlST V04.07 and later.Input to the I/O pack is through dual RJ-45 Ethernet connectors and a 3-pin power input.Output is through a DC-62 pin connector that connects directly with the associated terminal board connector. One of the Ethernet ports can be used to support Ethernet Modbus communication on Simplex networks. Visual diagnostics are provided through indicator LEDs.
➢➢To install the PSCA I/O pack
1.Securely mount the desired terminal board.
2.Directly plug one PSCA I/O pack into the SSCA terminal board connector.
3.Mechanically secure the I/O packs using the threaded inserts adjacent to the Ethernet ports. The inserts connect with a
mounting bracket specific to the terminal board type. The bracket location should be adjusted such that there is no right
angle force applied to the DC-62 pin connector between the I/O pack and the terminal board. The adjustment should only
be required once in the service life of the product.
4.Plug in one or two Ethernet cables depending on the system configuration. The I/O pack operates over either port. If dual
connections are used, standard practice is to hook ENET1 to the network associated with the R controller; however, the
PSCA is not sensitive to Ethernet connections and will negotiate proper operation over either port.
5.Apply power to the I/O pack by plugging in the connector on the side of the pack. It is not necessary to remove power from the cable before plugging it in because the I/O pack has inherent soft-start capability that controls current inrush on power application.
6.From the ToolboxST* application, add the PSCA module, and add and configure the required devices. From the Component Editor, press F1 for help.
Serial Channels：
The PSCA board in the I/O pack contains six independently configurable serial channels. Each of the ports can support the following modes: RS-232, RS422, RS 485 half-duplex. Jumpers on the SSCAH2A terminal board are used to set up the terminal scheme for the selected communication mode. For details on proper wiring and jumper settings for the supported modes.
Serial Modbus Master Service：
The current Modbus design supports the Master mode on all six serial ports. It is configurable at the port level as follows:
• Physical connection: RS-232, RS-422, RS-485
• Baud Rate: 300, 600, 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200
• Parity: none, odd, even
• Data Bits: seven, eight
• Stop Bits: one, two
• Station addresses
• Multidrop is applicable only to RS-485 with up to eight devices per port; maximum of 18 devices per board
• For RS-232 or RS-422, only one station is supported for these protocols
• RTU
• Time-out (milliseconds) per device
• 32–bit data Word ordering (for example, Least Significant Word [LSW] or Most Significant Word [MSW] first)
• Device response delay time
The Modbus service is configurable at the signal level as follows:
• Signal type
• Register number
• Read/write
• Transfer rate, 0.5, 1, 2, or 4 Hz
• Scaling: Raw min/max, Eng min/max
The service supports function codes 1-7, 15, and 16; it also supports double 16-bit registers for floating point numbers and 32-bit counters. It periodically (10 sec) attempts to reestablish communications with a dead station.Type casting and scaling of all I/O signals to/from engineering units are supported on the PSCA and the ToolboxST*application, for both fixed I/O and Modbus I/O.
