Connection: The 22-SCM-232 connects to the front port on the MicroLogix 1000 by using a 1203-SNM Null Modem adapter and a 1761-CBL-AP00 programming cable. The RJ45 cable on the 22-SCM-232 conencts to the RJ45 port on the PowerFlex 4/40. The SCM provides both media (RS232 to RS485) and protocol (DF1 to Modbus RTU) conversions.

Additional PF4/40 drives can be added. Use one AK-U0-RJ45-SC1 Splitter Cable for connecting to the first drive, and one AK-U0-RJ45-TB2P for every drive. The "Local Node Address" in the MSG instruction indentifies the drive node to communicate with.

PF4 Parameters: 22-SCM-232 parameters: 36 [Start Source] = 5 (Comm Port) 1[Adapter Cfg] = RTU Master 38 [Speed Reference] = 5 (Comm Port) 2[DF1 Addr Cfg] = 1 (this MUST equal Parameter 104 of the PF 4/40 it is connected to) 103 [Comm Data Rate] = 4 (19.2K) 3 [DF1 Rate Cfg] = 19.2k bps 104 [Comm Node Addr] = 1 107 [Comm Format] = 0 (RTU 8-N-1)

For the PowerFlex 4/40 drives, 19.2K and 8-N-1 are a requirement and can not be changed. The data rate of the controller and SCM MUST be equal to each other, but can be set faster or slower than the drives baud rate if desired. It is recommended that 19.2K be used for ALL serial connections (controller, SCM, and drives) to be consistent and to avoid any errors.

This rung clears the read data area (N7:10-19) on the first program scan (N7:0 = a constant 0) and starts the messaging process by clearing the EN bit of the first MSG instruction.

This rung resets all MSG instructions when the last MSG instruction has completed. Since the Parameter 39 Write and Read MSG's are on demand and not continuous, the "last" MSG in the sequence can vary.

The Write (B3:0/0) and Read (B3:0/1) requests are also reset. This prevents these MSG's from operating continuously while providing feedback to the user program that they have completed.

For demonstration purposes, the value of analog POT0 on the LRP processor is used to generate the Reference. Since the pot has a range of 0-250 (equates to 0.0 to 25.0 Hz), the pot value is multiplied by 3 to provide a range of 0 to 750 (0.0 to 75.0 Hz). Note that P034 [Minimum Freq] and P035 [Maximum Freq] on the drive determine the actual output frequency range on the drive. The default is 0.0 to 60.0 Hz.

A Application Code

Code that runs in the serial converter module after the boot code calls it. It performs the normal operations of the system.

B BCC

Block Check Character. An error detection scheme where the 2’s complement of the 8-bit sum (modulo-256 arithmetic sum) of all data bytes in a transmission block. It provides a means of checking the accuracy of each message transmission.

Boot Code

Code that runs when the serial converter module first receives power. It checks basic operations and then calls the application code.

C CRC

Cyclic redundancy check. An error detection scheme where all of the characters in a message are treated as a string of bits representing a binary number. This number is divided by a predetermined binary number (a polynomial) and the remainder is appended to the message as a CRC character. A similar operation occurs at the receiving end to prove transmission integrity.

Glossary

D DF1 Protocol

A peer-to-peer link layer protocol that combines features of ANSI X3.28-1976 specification subcategories D1 (data transparency) and F1 (two-way simultaneous transmission with embedded responses).

DF1 Rate

A unit of signaling speed equal to the number of discrete conditions or signal events per second. It is also called “baud rate” or “serial port rate.”

DSI

Drive Serial Interface - a modification of the ModBus RS-485 serial communications protocol used by various Allen-Bradley drives and power products.

DSI Peripheral

A device that provides an interface between DSI and a network or user. Peripheral devices are also referred to as “adapters” and “modules.” The

Glossary-2

serial converter module and PowerFlex 4-Class HIMs (22-HIM*) are examples of DSI peripherals.

DSI Product

A device that uses the DSI communications interface to communicate with one or more peripheral devices. For example, a motor drive such as a PowerFlex 4-Class drive is a DSI product. In this manual, a DSI product is also referred to as “product” or “host.”

DriveExplorer Software

DriveExplorer software is a tool for monitoring and configuring Allen-Bradley products and adapters. It can be run on computers running Microsoft Windows 95, Windows 98, Windows NT (version 4.0 or higher), Windows ME, Windows 2000, Windows XP, and Windows CE (version 2.0 or higher) operating systems. DriveExplorer (version 3.01 or higher) can be used to configure this serial converter module and PowerFlex 4-Class drives. A free version of DriveExplorer Lite is included with the serial converter module. Information about DriveExplorer software can be accessed at http://www.ab.com/drives/ driveexplorer.

DriveTools Software

A software suite designed for Microsoft Windows 95, Windows 98, and Windows NT (4.0 or higher) operating systems. To fully utilize DSI products, use DriveTools 2000 version 1.01 or higher. This software suite provides a family of tools that you can use to program, monitor, control, troubleshoot, and maintain Allen-Bradley products. Information about DriveTools can be accessed at http://www.ab.com/drives.

F Fault Action

A fault action determines how the serial converter module and connected drive act when a communications fault (for example, a cable is disconnected) occurs or when the scanner is switched out of run mode. The former uses a communications fault action, and the latter uses an idle fault action.

Flash Update

The process of updating firmware in the serial converter module.

H Hold Last

When communications are disrupted (for example, a serial cable is disconnected), the converter module and PowerFlex drive can respond by holding last state. Hold last state results in the drive receiving the last data received via the DF1 connection before the disruption. If the drive

Glossary-3

was running and using the Reference from the converter module, it will continue to run at the same Reference.

N Non-Volatile Storage (NVS)

NVS is the permanent memory of a device. Devices such as the serial converter module and drive store parameters and other information in NVS so that they are not lost when the device loses power. NVS is sometimes called “EEPROM.”

P PCCC (Programmable Controller Communications Command)

PCCC is the protocol used by some controllers to communicate with devices on a network. Some software products (for example, DriveExplorer and DriveTools 2000) also use PCCC to communicate.

PowerFlex 4-Class Drives

The Allen-Bradley PowerFlex 4-Class family of drives include the PowerFlex 4 and PowerFlex 40. These drives can be used for applications ranging from 0.2 kW (0.25 HP) to 7.5 kW (10 HP). All PowerFlex 4-Class drives implement DSI, allowing them to use the 22-SCM-232 serial converter module.

S Serial Converter

The serial converter provides an electronic communications interface between any Allen-Bradley DSI product and a computer with an RS-232 port. This converter uses a full-duplex RS-232 DF1 protocol. The serial converter may also be referred to as “22-SCM-232 converter,” “converter,” “DSI peripheral.”

Status Indicators

Status indicators are LEDs that are used to report the status of the serial converter module. There are three status indicators on the converter.

X Xmodem

Developed by Ward Christensen in 1978, Xmodem is a protocol used to transfer data. You can use the Xmodem protocol to flash the firmware in the serial converter module or a device connected to it.

Z Zero Data

When communications are disrupted (for example, a serial cable is disconnected), the serial converter module and drive can respond with

Glossary-4

zero data. Zero data results in the drive receiving zero as values for command data. If the drive was running and using the Reference from the converter module, it will stay running but at zero Reference.
