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.

Communicate with Your ArmorBlock Module
This ArmorBlock module’s I/O is exchanged with the master through a
poll, bit strobe or change of state connection.
When set for Polled, Bit Strobe, or change of state, the module consumes
and produces as follows:

Type of I/O Connections Consumes Produces
Polled 1 Bytes 2 Bytes
Bit Strobe
Change of State
0 Bytes 2 Bytes
0 Bytes 2 Bytes
Polled device – a master initiates communication by sending its polled
I/O message to the ArmorBlock module. The 8 input/8 output module
consumes the message, updates outputs, and produces a response that
reflects the status of 1) its inputs, and 2) any input or output faults.
Change of state device – productions occur when an input or fault
condition changes. If neither has occurred within the “expected packet
rate,” a heartbeat production occurs. This heartbeat production tells the
scanner module that the ArmorBlock module is alive and ready to
communicate.
Bit Strobe device – a master initiates communication by sending its bit
strobe I/O message. All bit strobed devices then respond. The 8 input/8
output module consumes the message, and produces a response that
reflects the status of inputs and outputs.
Refer to the table below for the word/bit definitions.

Note: This
module contains a circuit to protect the DeviceNet power supply from short
circuits in an attached sensor or sensor cable. If you connect a sensor while the
module is powered, the surge current produced by the sensor can cause the
module to fault. This operation is normal.
