Preface

Who Should Use This Manual

Purpose of this Manual

Use this manual if you are responsible for programming, or troubleshooting control systems that use GuardPLC controllers.

Personnel responsible for installation, programming, operation, and troubleshooting of safety-related controllers must be familiar with relevant safety standards for Programmable Electronic Systems (PES).

The manual provides procedural information on programming your controller system, including information on establishing communication between your programming terminal and the GuardPLC controller, creating a GuardPLC project, adding GuardPLC distributed I/O to your project, and creating user-defined function blocks.

For information on installing, configuring, operating, and monitoring the status of your GuardPLC controller system, refer to the GuardPLC Controller Systems User Manual, publication number 1753-UM001.

This manual does not provide information on SIL 3 or Cat. 4 safety application requirements. For detailed information on the safety policy regarding GuardPLC controllers, including information on the controller’s central functions, input and output channels, operating system, application program safety and regulations for use, refer to the GuardPLC Controller Systems Safety Reference Manual, publication number 1753-RM002.

Connect to the Controller via RSLogix Guard PLUS! Software

You connect the controller to the programming terminal via an Ethernet port on the controller. The programming terminal must have an Ethernet port or Ethernet communication card.

To directly connect the programming terminal to the controller, use a cross-over Ethernet cable. The GuardPLC 1600 and 1800 controllers feature auto-sensing ports so that a cross-over or straight-thru cable may be used.

Understand Ethernet Addressing

Publication 1753-PM001A-EN-P - November 2005

As with any connection between devices on Ethernet, the IP address and subnet mask determine if the connection can take place. Every device on Ethernet has an IP address and subnet mask.

The IP address and subnet mask are made up of four (4) octets (001.002.003.004) The IP address is made up of the Network ID

Connect to the GuardPLC Controller 1-3

(octets 001 and 002) and the Host ID (octets 003 and 004). The Network ID portion of the IP address is derived from the subnet mask.

When any two devices attempt to talk on Ethernet, a check is made to see if the Network ID of both the originator and the destination address match. If they match, then the message is sent on the local network. If they do not match, then the message is sent to the Gateway to route the message to the destination. The subnet masks of all the devices on a local network should be the same.

The example below illustrates how to derive the Network ID based on the GuardPLC controller’s IP address and subnet mask defaults.

EXAMPLE

Determine the Network ID

Default Settings: IP Address 192.168.0.99 = 11000000 . 10101000 . 00000000 . 01100011 Subnet Mask 255.255.252.0 = 11111111 . 11111111 . 11111100 . 00000000 Network ID = 11000000 . 10101000 . 000000xx . xxxxxxxx

Set up the programming terminal’s IP address so that it has the same Network ID as the GuardPLC controller. Octets one and two have to be the same because the subnet mask octets are 255. The third subnet mask octet is 252, which means that only the last two bits can be different.

If the factory default settings above are used, the allowable IP addresses for the programming terminal running RSLogix Guard PLUS! software are:

• 192.168.0.xxx (xxx represents any value between 000-255)

• 192.168.1.xxx

• 192.168.2.xxx

• 192.168.3.xxx

Configure the IP Address of Your Programming Terminal

IMPORTANT

The first time you connect to a controller, you must use the factory-set IP address of 192.168.0.99 and the default SRS of 60000. After you establish communications with the controller (using the steps on the following pages), you can change the IP address and SRS to better accommodate your Ethernet network.

Publication 1753-PM001A-EN-P - November 2005

1-4 Connect to the GuardPLC Controller

Change the IP address of your programming terminal running RSLogix Guard PLUS! software so that the GuardPLC controller and programming terminal can communicate on a local network.

TIP

If you suspect the GuardPLC controller has the factory-set default IP address of 192.168.0.99 and the default subnet mask of 255.255.252.0, set your programming terminal’s IP address to 192.168.0.98 with a subnet of 255.255.252.0 to establish communications.

To change the IP address:

1. In Windows 2000, choose Start>Setting >Control Panel>Network and Dial-up Connections.

2. Open Local Area Connections and click Properties. Select TCPIP and click Properties.

3. Set the General TCP/IP Properties as shown below.

Publication 1753-PM001A-EN-P - November 2005

4. Confirm your settings by clicking OK in both dialog boxes.

Notes:

(1) Assume correct SRS was entered in Step 3.

(2) The controller reverts back to its prior settings if it is not re-configured before the next power cycle.

(3) If the controller was previously running and the SRS was changed in Step 5, or if the controller is new (out-of-box), the only way to clear the FAULT is to download a program with a matching SRS.

To reset the controller:

1. Hold down the Reset button, then power cycle the GuardPLC controller.

2. Continue to hold down the Reset button until the PROG led stops flashing.

At the next power cycle, the settings will revert back to the last configured settings. These could be the settings in place prior to the Reset operation, if you did not reconfigure them after resetting the controller.

Step 10: Ping the Controller

Use the Start menu to open the RSLogix Guard PLUS! Command Prompt.

1. Choose Start>Programs>RSLogix Guard PLUS>RSLogix Guard PLUS Command Prompt.

2. Run IPCONFIG at the DOS Command prompt to verify your computer’s IP address. It must be on the same local network as the GuardPLC controller.

3. Ping the GuardPLC controller using the command shown at the C:\> below. If the ping is successful, the IP address of the GuardPLC controller has been verified and the Ethernet link is operating. If the ping was not successful either the IP address, subnet mask, or Ethernet link is not correct. The picture below is the result of a successful ping.

4. Type EXIT at the command prompt to close the Command Prompt window.

Step 11: Configure the GuardPLC Controller’s IP Address

1. Expand the project tree in the Hardware Management window until the controller COM icon is visible.

2. Right-click COM and choose Properties.

To recover from this fault:

1. Choose Extra>Change System ID from the Control Panel.

2. Verify that 60000 appears in the first window with 0 in the

second, as shown below.

3. Click OK.

The Fault LED should turn off, and the Control Panel should show that the CPU State has changed to STOP/VALID CONFIGURATION, as shown below.

Publication 1753-PM001A-EN-P - November 2005

TIP

The Online indicator is white because the GuardPLC controller is in STOP/VALID mode.

Configure the Programming Terminal

Specify the Host SRS

From the Hardware Management window, you can specify the host SRS of the programming terminal.

1. Right-click Programming Terminal and choose Properties.

2. Enter the host SRS (1 to 65535) for the programming terminal.

Make sure the host SRS of the programming terminal is not identical to the system ID (SRS) of any other controllers or programming terminals.

In a network, as many as five programming terminals can connect to the same controller at the same time. However, only one programming terminal can have read/write access.

If another controller logs in with read access, that additional user can query controller states and parameters (RUN, STOP, controller switches, etc.) with the Control Panel. The additional user can also display data values if the programming terminal has the same configuration as the controller.

If there are multiple programming terminals in one network, each programming terminal must have a unique host SRS.

Login Dialog

The Login dialog defines the communication parameters between the controller and the programming terminal.

Field Description

IP address The IP address of the controller on the Ethernet network.

The factory-set IP address is 192.168.0.99.

SRS SRS stands for System, Rack, Slot. The rack and slot IDs are already preset by the controller, so you only

need to enter the system ID. You can enter any number from 1 to 65,535. However, the number must be unique from the programming terminal and from any other GuardPLC controllers on the same Peer-to-Peer Ethernet.

The default (factory-set) SRS is 60000.

Username

(default = Administrator)

Password

(default = <blank>)

Access Type Your access level.

Your username.

The Administrator assigns a username. The username is sensitive to upper and lower case characters. A username can only contain letters, numbers, and underscore characters. You can define as many as 10 usernames per GuardPLC controller.

Your password.

An Administrator assigns a password. The password is case sensitive. A password can only contain letters, numbers, and underscore characters.

Administrator highest privileges

manage usernames and passwords read data from controller write routines and data into controller force tags stop, start, freeze, and force a routine download an operating system change IP address and system ID reboot the controller can also login under read/write and read levels

Read/Write read data from controller

write routines and data into controller force tags start, stop, freeze, and force a routine can also login under read level

Read lowest privileges

only read data from controller

As many as five users can login to the same controller at the same time; however, only one of those users can login as Administrator or Read/Write. The others must login with Read access. If you login while someone else is logged in with Administrator or Read/Write access, you automatically get Read access, regardless of the access type you select.

For new controllers, and if the backup battery was removed from a GuardPLC 1200 or 2000 controller, access is available using the following system defaults:
