4.4 Setting the Data Rate

If the Data Rate switch on the module is set to “PGM,” the value of module parameter 5 (DF1 Rate Cfg) determines the RS485 DF1 data rate. Your application may require a different setting.

Step 1. Set the value of module parameter 5 (DF1 Rate Cfg) to the data rate at which your network is operating. Refer to figure 4.3.


4.5 Setting the Error-Checking Method

Two types of error-checking methods are used with the DF1 protocol: Cyclic Redundancy Check (CRC) and Block Check Character (BCC). (Refer to the Glossary for a description of each method.)

Step 1. Set the value of module parameter 24 (CRC/BCC) to the method used by the network as shown in figure 4.4.

4.6 Setting the I/O Configuration

The I/O configuration determines the type of data sent to the drive. This is a two-part process: enabling/disabling the data transmitted between the module and the drive, and identifying the data transmitted between the module and the master (i.e., scanner).

Step 1. Enable or disable the data transmitted between the module and the drive by setting the bits in module parameter 12 (DPI I/O Config).

A “1” enables the I/O. A “0” disables the I/O. Bit 0 is the right-most bit. In figure 4.5, it is highlighted and equals “1.”

Step 2. If Logic Command/Reference is enabled (default), configure the parameters in the drive to accept the Logic Command and Reference from the module. For example, set Speed Ref A Sel (SP600 drive parameter 90) to “Network” so that the drive uses the Reference from the module. Also, verify that SP600 drive parameter 89 (Logic Source Sel) is configured to receive the desired logic from the module.

Step 3. If you enabled one or more Datalinks (optional), configure parameters in the drive to determine the source and destination of data in the Datalink(s). Also, ensure that the RS485 DF1 module is the only module using the enabled Datalink(s).


The module is ready to receive I/O from the master (i.e., scanner). You must now configure the scanner to recognize and transmit I/O to the module.

5 - 15 Not Used


4.7 Setting a Fault Action

By default, when communications are disrupted (for example, a cable is disconnected) or the scanner is idle, the drive responds by faulting if it is using I/O from the network.

You can configure a different response to communication disruptions using module parameter 10 (Comm Flt Action).

Set the value of module parameter 10 (Comm Flt Action) to the desired response as shown in table 4.2. See figure 4.6 for a sample LCD OIM Fault Action screen.

Changes to this parameter take effect immediately. A reset is not required.

!ATTENTION: Module parameter 10 (Comm Flt Action) lets you determine the action of the module and connected drive if communications are disrupted. By default, this parameter faults the drive. You can set the parameter so that the drive continues to run. Precautions should be taken to ensure that the setting of this parameter does not create a risk of injury or equipment damage.

Table 4.2 – Selections for Drive Response to Communication Fault

Value Action Description

0 Fault (default) The drive is faulted and stopped (Default).

1 Stop The drive is stopped, but not faulted.

2 Zero Data The drive is sent 0 for output data after a communications disruption. This does not command a stop.

3 Hold Last The drive continues in its present state.

4 Send Flt Cfg The drive is sent the data that you set in the fault configuration parameters 14 through 23 (Flt Cfg Logic through Flt Cfg D2 In).

4.7.1 Setting the Fault Configuration Parameters

If you set module parameter 10 (Comm Flt Action) to “Send Flt Cfg,” the values in the parameters shown in table 4.3 are sent to the drive after a communications fault occurs. You must set these parameters to values required by your application.

Changes to these parameters take effect immediately. A reset is not required.

4.7.2 Resetting the Module

Changes to switch settings or some module parameters require that you reset the module before the new settings take effect. You can reset the module by cycling power to the drive or by using module parameter 9 (Reset Module).

Table 4.3 – Fault Configuration Parameters

Parameter Number Name Description

14 Flt Cfg Logic A 16-bit value sent to the drive for Logic Command.

15 Flt Cfg Ref A 32-bit value (0 to 4294967295) sent to the drive as a Reference or Datalink.

Important: If the drive uses a 16-bit Reference or 16-bit Datalinks, the most significant word of the value must be set to zero (0) or a fault will occur.

16 - 23 Flt Cfg x1 In Flt Cfg x2 In

!ATTENTION: If the module is transmitting control I/O to the drive, the drive may fault when you reset the module. Determine how your drive will respond before resetting a connected module. Failure to observe this precaution could result in bodily injury or damage to equipment.


Set module parameter 9 (Reset Module) to “Reset Module.” See figure 4.7.

When you enter 1 (“Reset Module”) the module is immediately reset. When you enter 2 (“Set Defaults”) the module sets all module parameters to their factory-default settings. The module should be reset after performing a “Set Defaults.”

The value of this parameter is restored to 0 (“Ready”) after the module is reset.

C-4 RS485 DF1 Communications Module

Glossary Glossary-1

GLOSSARY

BCC (Block Check Character) - A technique for error detection in data communications. A character is added to a transmission block, which is compared with a second BCC computer by the receiver to determine if the transmission is error free.

controller - Also called programmable logic controller. A solid-state control system that has a user-programmable memory for storage of instructions to implement specific functions such as I/O control, logic, timing, counting, report generation, communication, arithmetic, and data file manipulation. A controller consists of a central processor, input/output interface, and memory. See also scanner.

CRC (Cyclic Redundancy Check) - A commonly used technique for error detection in data communications. A polynomial algorithm is performed on the data, and the resultant checksum is appended at the end of the frame. The receiving device performs a similar algorithm.

data rate - The speed at which data is transferred on the RS485 DF1 network. Each device on an RS485 DF1 network must be set for the same data rate. You can set the RS485 DF1 module to 1200, 2400, 4800, 9600, 19.2 K or 38.4 kbps.

Datalink - A type of pointer used by some SP600 drives to transfer data to and from the controller. Datalinks allow specified parameter value(s) to be accessed or changed without using explicit messages. When enabled, each Datalink consumes either four bytes or eight bytes in both the input and output image table of the controller. The drive determines the size of Datalinks.

DF1 - A Rockwell Automation Datalink layer protocol that combines features of subcategories D1 (data transparency) and F1 (two-way simultaneous transmission with embedded responses) of ANSI x3.28 specification.

DPI (Drive Peripheral Interface) - A peripheral communication interface used by various Reliance Electric drives and power products.

DPI peripheral - A device that provides an interface between DPI and a network or user. Peripheral devices are also referred to as “modules” and “adapters.” The RS485 DF1 module and SP600 OIM are examples of DPI peripherals.

Glossary-2 RS485 DF1 Communications Module

DPI product - A device that uses the DPI communications interface to communicate with one or more peripheral devices. For example, a motor drive such as a SP600 drive is a DPI product. In this manual, a DPI product is also referred to as “product” or “host.”

fault action - Determines how the module and connected product 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.

fault configuration - When communications are disrupted (for example, a cable is disconnected), the module and SP600 drive can respond with a user-defined fault configuration. The user sets the data that is sent to the drive in the fault configuration parameters (parameters 15 (Flt Cfg Logic) through 24 (Flt Cfg D2 In)). When a fault action parameter is set to use the fault configuration and a fault occurs, the data from these parameters is sent as the Command Logic, Reference, and/or Datalink(s).

flash update - The process of updating firmware in the module. The module can be flash updated using the X-Modem protocol and a RECOMM-232 serial converter.

hold last - When communications are disrupted (for example, a cable is disconnected), the module and SP600 drive can respond by holding last. Hold last results in the drive receiving the last data received via the RS485 DF1 connection before the disruption. If the drive was running and using the reference from the module, it will continue to run at the same reference.

II/O data - I/O data, sometimes called “implicit messages” or “input/output,” transmit time-critical data such as a Logic Command and Reference. The terms “input” and “output” are defined from the scanner’s point of view. Output is transmitted by the scanner and consumed by the module. Input is transmitted by the module and consumed by the scanner.

Logic Command/Logic Status - The Logic Command is used to control the SP600 drive (for example, start, stop, direction). It consists of one 16-bit word of input to the module from the network. The definitions of the bits in this word depend on the drive.

The Logic Status is used to monitor the SP600 drive (for example, operating state, motor direction). It consists of one 16-bit word of output from the module to the network. The definitions of the bits in this word depend on the drive.

Glossary Glossary-3

module - Devices such as drives, controllers, and computers usually require a module to provide a communication interface between them and a network such as RS485 DF1. An module reads data on the network and transmits it to the connected device. It also reads data in the device and transmits it to the network.

The RS485 DF1 module connects SP600 drives to an RS485 DF1 network. Modules are sometimes also called “adapters,” “cards,” “embedded communication options,” “gateways,” and “peripherals.”

node address - An RS485 DF1 network can have as many as 255 devices connected to it. Each device on the network must have a unique node address from 0 to 254.

non-volatile storage (NVS) - NVS is the permanent memory of a device. Devices such as the 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.”

operator interface module (OIM) - A device that can be used to configure and control a SP600 drive.

PCCC (Programmable Controller Communications Command) - The protocol used by some controllers to communicate with devices on a network. Some software products (for example, VS Utilities) also use PCCC to communicate.

ping - A message that is sent by a DPI product to its peripheral devices. They use the ping to gather data about the product, including whether it can receive messages and whether they can log in for control.

Reference/Feedback - Reference is used to send a reference (for example, speed, frequency, torque) to the product. It consists of one word of input to the module from the network. The size of the word (either a 16-bit word or 32-bit word) is determined by the drive.

Feedback is used to monitor the speed of a product. It consists of one word of output from the module to the network. The size of the word (either a 16-bit word or 32-bit word) is determined by the drive.

scanner - A separate module (of a multi-module controller) or a built-in component (of a single-module controller) that provides communication with modules connected to a network. See also controller.

status indicators - LEDs that are used to report the status of the module, network, and drive. They are on the module and can be viewed on the front cover of the drive when the drive is powered.

Glossary-4 RS485 DF1 Communications Module

Type 0/Type 1/Type 2 Control - When transmitting I/O, the module can use different types of messages for control. The Type 0, Type 1, Type 2 control events help Reliance Electric personnel identify the type of message that a module is using.

transaction number (TNS) - A two-byte field in a DF1 message packet that is used in combination with the SRC (source node of the message) and CMD (command code) bytes to uniquely identify every message packet. The TNS typically increments each time a new DF1 message is sent. The reply message will contain the same TNS value.

VS Utilities software - A Windows-based software tool for monitoring and configuring Reliance Electric products and modules. VS Utilities can be used to configure the RS485 DF1 module and SP600 drives.

zero data - When communications are disrupted (for example, a cable is disconnected), the module and drive can respond with 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 module, it will stay running but at zero reference.
