Chapter 1 Communicate with I/O Modules
EXAMPLE
In the following scenario, Disable Keying allows I/O
communication:
The module configuration is for a 1756-IA16 digital input module. The
physical module is a 1756-IB16 digital input module. In this case,
communication is allowed because the two digital modules share
common data formats
.
IMPORTANT
Changing electronic keying selections online may cause the I/O
communication connection to the module to be disrupted and
may result in a loss of data.
