Install Your ArmorBlock-LP Module
Installation of the ArmorBlock-LP module consists of:
• setting the node address and communication rate in the ArmorBlock
module
• mounting the ArmorBlock module
• connecting the wiring
• communicating with your module
Set the Node Address
Each ArmorBlock-LP comes with its internal program set for node
address 63 and a communication rate of 125K bps. To set the node
address and communication rate, you need the following:
• host computer with DeviceNet Manager Software (or similar
configuration software tool)
• 1770-KFD RS-232 module (or similar interface)
• suitable cables to connect the 1770-KFD to your module and to
connect the 1770-KFD to your host computer
Set up a system (as shown below) to communicate with your
ArmorBlock module to set the node address and communication rate to
meet your system requirements.
