Chapter 3 Installing the Module
Before You Begin
Initial Checks
Before you install your module, you need to: z determine how the NOE 771 x0 module will be assigned its Ethernet address parameters (the default method is BOOTP) z verify that your Ethernet network is properly constructed
CAUTION
DUPLICATE ADDRESS HAZARD
Do not connect the module to your network until you have ensured that its IP address will be unique on the network. Having two devices with the same IP address can cause unpredictable operation of your network.
Failure to observe this precaution can result in network disruption leading to possible injury or equipment damage.
Determining the
Appropriate
Ethernet
Address
Parameters
Consult your system administrator to determine if you must configure a new IP address and appropriate gateway and subnet mask addresses, or whether the module will obtain its Ethernet address parameters from a BOOTP server. If the administrator assigns new address parameters, follow the directions in Chapter 4 to configure the module from your programming panel.
Note: If you will be changing the default configuration, you should stop the controller, then install the module, then change the configuration before starting the controller again.
The NOE 771 x0 module only reads its configuration data at power-up and when it is reset. Whenever the configuration data is changed, the module must be reset, either by hot swapping or through a reset command in the MSTR block (see Reset
Option Module MSTR Operation section in Chapter 6). Once the module is installed, stopping and restarting the controller will not reset it.
