DeviceNet 1732 ArmorBlock I/O, Series A
Change-of-State
- productions occur when an input changes or a
fault condition occurs. If no input or fault condition change occurs
within the expected packet rate, a heartbeat production occurs. This
heartbeat production tells the scanner module that the I/O module is
alive and ready to communicate. Consumption occurs when data
changes and the master produces new output data to the I/O block.
1732D-8CFGM8 and 1732D-8CFGM12
Note that the 1732D-8CFGM8 and 1732D-8CFGM12 self-assigning
modules contain both input and output functionality. These modules
do not need to be configured.
If an I/O point is to be an output, dedicate that point as an output
with a wired load and energize it through a control program.
If an I/O point is to be an input, wire the input device as normal and
leave the associated output un-energized at all times.
