Chapter 3 Install the Module
Set the Node Address of a
POINT Guard I/O Module
Use RSNetWorx for DeviceNet software to set the node address of POINT
Guard I/O modules. The module has an out-of-box preset node address of 63.
We suggest that you connect and set the modules one at a time. Otherwise, the
address conflicts (all of them at 63) will prevent communication with some of the
modules.
Follow these steps to set the node address with the node commissioning tool.
1. Choose Start>Programs>Rockwell Software>RSNetWorx>DeviceNet
Node Commissioning Tool.
2. Click Browse.
3. Check ‘I want to input the address for the device on the selected network’.
The unique identifier for a safety node is a combination of the
safety network number (SNN) and node address. When the
SNN is set, the current node address is used to generate and
store this identifier in flash memory. Once the identifier is set,
for safety reasons, the node address cannot be changed unless
specific action is taken to reset the POINT Guard I/O module’s
SNN. For this reason, you are required to set the node
address prior to applying a SNN.
