To obtain a copy of the Enhanced and Ethernet PLC-5 Programmable Controllers User Manual, publication 1785-UM012, you can: • view or download an electronic version from the Internet at www.rockwellautomation.com/literature. • contact your local distributor or Rockwell Automation representative to place an order.
Ethernet PLC-5 Programmable Controllers About the Controllers The following illustrations indicate the controller’s front panel components.
Ethernet PLC-5 Programmable Controllers 7 New Features The controllers contain an RJ-45 connector for the Channel 2 communication port.
Ethernet PLC-5 Programmable Controllers Similarly, if you have a dynamic network configuration, DHCP or BOOTP assigns the controller’s hostname. With a static configuration, you assign the hostname. When you create a hostname, consider these naming conventions. • The hostname can be a text string up to 24 characters. • The hostname can contain alpha (A to Z) numeric (0 to 9) and may contain a period and minus sign. • The first character must be an alpha character.
Ethernet PLC-5 Programmable Controllers 9 The unchecked Auto Negotiate box and corresponding port settings are shown below. The checked Auto Negotiate box and corresponding port settings are shown below. Email Client Functionality The controller is an email client that sends an email triggered by a message instruction via a mail relay server. The controller uses standard SMTP protocol to forward the email to the relay server. The controller does not receive email.
Ethernet PLC-5 Programmable Controllers To create an email: 1. Create a message instruction similar to the one below. The destination (to), the reply (from), and the body (text) are stored as strings in elements of separate ASCII string files. If you want to send an email to a specific recipient when a controller application generates an alarm or reaches a certain condition, program the controller to send the message instruction to the destination of the email. 2. Verify the rung. 3.
Ethernet PLC-5 Programmable Controllers 11 4. To send email, enter the appropriate information into the Data fields and Username and Password, if Authentication is enabled. Examine the Error Code (denoted in Hex) and Error Description areas within the General tab to see if the message was successfully delivered. Error Code (hex) Description 0x000 Delivery successful to the mail relay server. 0x002 Resource unavailable.
Ethernet PLC-5 Programmable Controllers Enable/Disable HTTP Web Server You can disable the HTTP web server functionality from within the Channel 2 Configuration by unchecking the HTTP Server Enable check box shown below. SNMP Server Enabled HTTP Server Enabled The default (checked box) lets you connect to the controller using a web browser.
