Modes of Operation

Chapter 4 contains the following information:

• Powering up the drive with the RS1 Module installed.

• The modes of operation and LED indications.

Powering Up the Drive

LED Indicators

After you have installed the RS1 Module, apply power to the drive and to the connected device. The READY LED should illuminate. If it does not, refer to Chapter 9, Troubleshooting.

The RS1 Module has three LEDs (see ﬁgure below) which provide module status.

READY LED

FAULT LED

COMM LED

RS232 Serial Comm

READY

FAULT

COMM

The LEDs are deﬁned as follows:

• COMM – The COMM LED has four possible states:

Green (solid) The cable is connected (both ends) and module is ready to

communicate. Green (flashing) The module is on-line and communicating. Red (solid) Connection was lost or application timed out. Red (flashing) Device is transmitting & receiving data but application has timed out.

•FAULT – This LED tracks the fault status of the 160 Drive.

When no faults are present, the LED will be off. The LED will illuminate (red) if a drive fault occurs.

• READY – The Ready LED will illuminate (green) whenever the

module is connected to the drive and power is applied.

4–2 Modes of Operation

Modes of Operation

The RS1 Module has three modes of operation.

• Power-up mode

• Run mode

• Error mode

Power-up Mode

The following sequence of operation occurs:

1. During power-up, the READY LED illuminates.

2. The module reads and stores the DIP switch settings.

If the power-up sequence is successful, the module enters the run mode and the COMM LED ﬂashes green or turns solid green.

If the power-up sequence fails, the COMM LED will go to solid red and the module will enter the Error Mode. See the Error Mode description in this section.

Run Mode

After a successful power-up, the RS1 Module enters the run mode and operates as a slave device to a master device. In run mode, the module:

• Accepts and responds to messages from the master on the

network.

• Monitors cable integrity.

If an error is detected, the module enters error mode (see below).

Error Mode

If the module detects an error, the COMM LED ﬂashes red or turns solid red. Refer to Chapter 9 for details on how to recover from an error.

RS1 Data Table Interface

This chapter provides you with the following information:

• Supported PCCC commands of the RS1 Module.

• RS1 Module Data Table Structure.

Supported PCCC Command List

Data Table Structure

The RS1 Module communicates over RS-232 using the Allen-Bradley DF1 protocol. The DF1 protocol uses PCCC (Programmable Controller Communication Commands) to determine the data format. PCCC describes the action of the message (set or get) and the location of the data involved. For further PCCC information, refer to DF1 Protocol and Command Set Reference Manual, publication 1770-6.5.16.

The RS1 Module responds to the PCCC types shown in the following table.

Table 5.A PCCC Types

CMD Code FNC Code Command Name

0x06 0x03 Identify Host and some Status 0x0F 0x67 Typed Write (Logical ASCII Addressing only) 0x0F 0x68 Typed Read (Logical ASCII Addressing only) 0x0F 0xA2 Protected Type Logical Read with 3 Address Fields 0x0F 0xAA Protected Type Logical Write with 3 Address Fields 0x0F 0xA1 Protected Type Logical Read with 2 Address Fields 0x0F 0xA9 Protected Type Logical Write with 2 Address Fields

The RS1 Module maintains a data table that allows DF1 devices (such as an SLC 500 or MicroLogix 1000) to set or request data using standard PCCC. The data table in the RS1 Module contains:

• Drive parameter information

• RS1 parameter information

• Logic command & status data

• Speed command & status data

• Communication status information.

The data table is formatted as integer ﬁles and follows the form shown on the next page.

The “File Address” section of the data table is divided into eight areas, each having a different purpose.

1. Parameter Value Read or Write (N10). Reading data from ﬁles

in this area will cause the module to read parameter values from the device and send those values as the response to the read message. Writing data to ﬁles in this area will cause the module to write that data into device parameters.

2. RS1 Parameter Value Read or Write (N13). Reading data from

ﬁles in this area will cause the module to read parameter values from the RS1 and send those values as the response to the read message. Writing to N13 will cause changes to RS1 parameters.

3. Parameter Read Full (N30). This area is read-only. When read,

the data returned consists of 20 words of information about each parameter including scaling, parameter text, units text, minimum, maximum, and default values. When reading this area, set the number of elements to twenty times the number of parameters to be read.

Using the RS1 Module with a Programmable Controller

This chapter provides an overview of the steps needed to use the RS1 Module with a MicroLogix 1000 (or other Allen-Bradley programmable controllers). The programmable controller can send control messages to the RS1 Module and receive status messages back. The device also allows a ladder logic program to conﬁgure and read parameters from the 160 Drive.

This chapter contains the following information:

• How to setup the RS1 Module with a programmable controller.

• A sample ladder logic program to control the 160 Drive.

• A description of reading parameters using the Message (MSG)

Command.

• A sample ladder logic program to read parameters.

The MicroLogix 1000 Programmable Controller was used with RSLogix 500™ software for the examples shown in this chapter – the concepts demonstrated apply to other programmable controllers as well, including the SLC 500 and PLC-5.

Required Tools

Before continuing, the user should have read and understood:

• MicroLogic 1000 Programmable Controller User Manual,

Publication 1761-6.3 (or appropriate controller User Manual).

• SLC 500 and MicroLogix 1000 Instruction Set Reference Manual,

publication 1747-6.15.

8–2 Using the RS1 Module with a Programmable Controller

Setting the Drive to Enable Network Control

Setting the Baud Rate and Checksum Mode

The 160 drive must be conﬁgured to accept logic and speed commands from the network. This can be done by conﬁguring two of the 160 parameters:

1. Set P46 - [Input Mode] to a value of “2.” This will conﬁgure the

drive to accept the logic commands from the network.

2. Set P59 - [Frequency Select] to “1.” This will conﬁgure the drive

to accept speed commands from the network.

Changing the above parameters can be done with the 160 Keypad Module or conﬁguration software such as the DriveExplorer.

Important:

The baud rate and checksum mode on the RS1 Module should be conﬁgured to the desired setting for the network (and other devices). After conﬁguration, install the RS1 Module into the 160 Drive as explained in Chapter 3. Note that the MicroLogix uses CRC as the checksum mode.

For a new Input Mode to take affect, drive power must be cycled.

Connecting the Drive to the Programmable Controller

Controlling the Drive

The RS1 Module is connected to the programmable controller through the 9-pin D-shell connector. Since each programmable controller may have different wiring requirements, Figure 3.5 should be referenced as a guide.

Important:

Controlling the 160 Drive from a programmable controller is accomplished using Message Commands to communicate through the RS1 Module to the drive. To send a Start or Stop command to the drive, the Message Command (MSG) is set up to write to N41:0. To read the drive status, the Message Command is set up to read from N41:0. Refer to Chapter 6 for the logic command and status format. Drive speed can be controlled or read in the same manner by accessing N41:1.

The communication port of the programmable controller may also be used to program the controller, thus the user may haveto disconnect the cable going to the RS1 Module before programming the controller.

Using the RS1 Module with a Programmable Controller 8–3

Program the Ladder

The example ladder program in Figure 8.2 demonstrates writing a Logic Command to the drive and reading the Logic Status from the drive.

In the following example ladder program, B3:0/0 is set every 2 seconds. This enables a Logic Command write to be done followed by the Logic Status read. The data for the Logic Command is stored in N7:8 of the MicroLogix and is written to location N41:0 of the RS1 Module. For the Logic Status, data from the RS1 Module at location N41:0 is read by the MicroLogix and stored in N7:9. This ladder program could be modiﬁed to read and write speed commands for the 160 Drive by changing the read and write location in the RS1 Module from N41:0 to N41:1.

Reading and Writing Parameters

END

Reading or writing parameters can be accomplished using message commands to communicate through the RS1 Module to the drive. The drive parameters are accessed at location N10:XX, with the XX being the parameter number to read or write (i.e. N10:30 accesses parameter P30 - [Accel Time]).

Using the RS1 Module with a Programmable Controller 8–5

You can read or write RS1 Module parameters through location N10 or N13. For location N10, the RS1 parameters start at N10:101, thus accessing location N10:101 reads or writes RS1 parameter P1 - [Node Address]. For location N13, the RS1 parameters start at N13:1 (N13:1 also accesses RS1 parameter P1 - [Node Address]).

Program the Ladder for Parameter Reads and Writes

The example ladder program in Figure 8.4 accomplishes reading and writing drive parameters.

In the following ladder program, B3:1/4 is set when requesting a parameter write. When no other Message Commands are enabled, B3:0/4 will be set, starting the parameter write. For the parameter write, data from N7:51 is written by the MicroLogix to location N10:30 (P30 - [Accel Time]) of the RS1 Module. Bits B3:0/4 and B3:1/4 are cleared when the Message Command is completed.

B3:1/5 is set when requesting a read of a parameter. When no other Message Commands are enabled, B3:0/5 will be set, starting the parameter read. For the parameter read, location N10:30 (P30 - [Accel Time]) of the RS1 Module is read by the MicroLogix and the data is placed in N7:52. Bits B3:0/5 and B3:1/5 are cleared when the Message Command is completed.

Troubleshooting

The purpose of this chapter is to help you troubleshoot your RS1 Module.

ATTENTION: Servicing energized industrial control

equipment can be hazardous. Electrical shock, burns, or unintentional actuation of controlled industrial equipment may cause death or serious injury. Follow the safety-related practices of NPFA 70E, Electrical Safety for Employee Workplaces, when working on or near energizedequipment. Do not work alone on energized equipment.

ATTENTION: Do not attempt to defeat or override fault circuits. The cause of a fault indication must be determined and corrected before attempting operation. Failure to correct a drive or systemmalfunction may resultin personal injury and/or equipment damage due to uncontrolled machine system operation.

LED Indicators and Troubleshooting

The RS1 Status LEDs can help you troubleshoot the module in the event that problems occur. Refer to the paragraphs that follow for details.
