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.
