Configuring the Embedded Ethernet Interface

Before you can use the embedded Ethernet Interface, you must configure it using the programming software. To configure the embedded Ethernet interface:

1) In the Project tab of the Navigator, expand your PACSystems Target, the hardware configuration, and the main rack (Rack 0).

2) Expand the CPU slot (Slot 1). The Ethernet Interface daughterboard is displayed as Ethernet.

3) Right click the daughterboard slot and choose Configure. The Parameter Editor window displays the Ethernet Interface parameters.

Ethernet interface configuration includes the

following additional procedures. For details on completing these steps, refer to the PACSystems RX3i and RSTi-EP TCP/IP Ethernet Communications User Manual, GFK-2224.

• Assigning an IP Address for initial network operation, such as connecting the programmer to download the hardware configuration, using the Set Temporary IP Address utility (refer to Setting a Temporary IP Address) or by downloading a hardware configuration through a serial connection.

• Configuring the characteristics of the Ethernet interface.

• Configuring Ethernet Global Data, if used.

• (Optional, not required for most systems). Setting up the RS-232 port for Local Station Manager Operation. This is part of the basic Ethernet Interface configuration.

• (Optional, not required for most systems). Configuring advanced user parameters. This requires creating a separate ASCII parameter file that is stored to the Controller with the hardware configuration. The Ethernet Interface has a set of default Advanced User Parameter values that should be changed only in exceptional circumstances by experienced users.

• (Optional) Setting up the Controller for Modbus/TCP Server operation.

• Note: Whenever a CPE310 is configured as a CPU310, Ethernet properties cannot be configured.

• The embedded Ethernet interface is not supported when CPE310 is configured as a CPU310 and the Ethernet port should not be connected to any network because it may have adverse effects on the network and/or operation of the CPU.

Note: Whenever a CPE330 is configured as a CPU320, Ethernet properties cannot be configured.

However, the embedded Ethernet ports may be used with their default IP Addresses.

3.4.1 Establishing Initial Ethernet Communications

To establish Ethernet communications between the PME programming and configuration software and the CPU, you first need to set an IP address. Use one of the following methods:

Default IP Addresses

Initial Ethernet communication with the CPU may be established using the default IP addresses programmed at the factory:

RX3i CPE302/CPE305/ IP Address: 192.168.0.100 10.10.0.100 0.0.0.0 Subnet

Mask: 255.255.255.0 255.255.255.0 0.0.0.0

Gateway: 0.0.0.0 0.0.0.0 0.0.0.0 interface is not known, communication may be established using one of these methods to set a permanent IP address:

• Connect to the CPE302/CPE305/CPE310 via its serial port and assign an IP Address to the embedded Ethernet interface by downloading a hardware configuration.

• Connect to the CPE302/CPE305/CPE310 with PME using an IC695ETM001 module with a known IP address and located in the same rack. Download a new hardware configuration with the desired IP address for the embedded Ethernet interface.

Connecting to CPE330 Embedded Ethernet when IP Addresses are not known

If the IP Addresses of the CPE330 embedded LAN1 and LAN2 Ethernet interfaces are not known, communication may be established using one of these methods to set new IP addresses:

• Setting a Temporary IP Address using the Set Temporary IP Address tool in PAC Machine Edition (PME). After setting the temporary address, connect to the selected CPE330 LAN using PME and download a new hardware configuration with the desired permanent IP addresses.

• Connect to the CPE330 with PME using an IC695ETM001 module with a known IP address and located in the same rack. Download a new hardware configuration with the desired permanent IP addresses for the CPE330 embedded Ethernet interfaces.

Connecting to CPE400/CPL410 Embedded Ethernet when IP Addresses are not known

Use the OLED display to read the IP Address of any LAN.

Note: Setting a Temporary IP Address tool is not available for CPE400 or CPL410.

68 CPE LAN3 IP Address is not configurable.

CPE100/CPE115 Embedded Ethernet when IP Addresses are not known

restored by powering up the module with the pushbutton pressed and waiting until the OK LED flashes twice.

Note: Setting a Temporary IP Address tool is not available for CPE100/CPE115.

CAUTION

This procedure also erases the stored hardware configuration, logic and contents of the backup RAM.

3.4.2 Setting a Temporary IP Address

If supported by the host CPU⁶⁹, use the Set Temporary IP Address utility to specify an IP address in place of one that has been lost or forgotten.

The following restrictions apply when using the Set Temporary IP Address utility:

• To use the Set Temporary IP Address utility, the PLC CPU must not be in RUN Mode. IP address assignment over the network will not be processed until the CPU is stopped and is not

scanning outputs.

The Set Temporary IP Address utility does not function if communications with the networked PACSystems target travel through a router. The Set Temporary IP Address utility can be used if communications with the networked PACSystems target travel across network switches and hubs.

• The current user logged on the computer running the Set Temporary IP Address utility must have full administrator privileges.

• The target PACSystems must be located on the same local sub-network as the computer running the Set Temporary IP Address utility. The sub-network is specified by the computer's subnet mask and the IP addresses of the computer and the PACSystems Ethernet Interface.

Interface to which PME will be connected.

1. Connect the PACSystems CPU LAN to the Ethernet network on which PME is communicating.

2. In the Project tab of the Navigator, right click the PACSystems target, choose Offline Commands, and then choose Set Temporary IP Address. The Set Temporary IP Address dialog box (Figure 39) appears.

3. In the Set Temporary IP Address dialog box, do the following:

▪ Key in the 12-digit hexadecimal MAC address (two digits per field).

▪ In the IP Address to Set box, specify the temporary IP address you want to set for the PACSystems LAN.

▪ If necessary, select the Enable Network Interface Selections check box and specify the IP address of the network interface on which the PACSystems is located.

4. When the fields are properly configured, click the Set IP button.

5. The IP Address of the specified PACSystems LAN will be set to the specified temporary address. This may take up to a minute.

After the programmer connects over Ethernet, the permanent IP address for the Ethernet interface, which is set in the

hardware configuration, will have been downloaded to the CPU.

The temporary IP address remains in effect until the Ethernet interface is restarted, power-cycled or until the hardware configuration is downloaded or cleared.

CAUTION

The temporary IP Address set by the Set Temporary IP Address utility is not retained through a power cycle. To set a permanent IP Address, you must set the IP Address property of the target and download (store) HWC to the PACSystems.

The Set Temporary IP Address utility can assign a temporary IP Address even if the target Ethernet Interface has previously been configured to a non-default IP Address. (This includes overriding an IP Address previously configured by the programmer.)

Use this IP Address assignment mechanism with care.
