Configure Your Adapter and Digital Modules on a ControlNet Network Chapter 6
Slot Status Bits
The Slot Status bits display the connection status for each of the FLEX I/O
modules that use a rack-optimized connection.
• Adapter:I:slot status bits :3 and :4 correspond to the rack-optimized
connection in the 1794-ACN15 slots 3 and 4.
• Each of the other bits corresponds to a FLEX I/O module that may be
installed in the I/O backplane.
In this example, the 1794-ACN15 adapter is using three direct connections; slot
0 is a 1794-IE12 module, slot 1 is a 1794-OE12 module, and slot 2 is a
1794-IB8XOB4 module. Slot 3 is a 1794-IB16D, and slot 4 is a 1794-OB16D
module, both connected using rack-optimized connections. All modules are
installed and operating correctly with (0 = no error). A 1 would indicate “no
connection error,” (typically, module removed or missing).
Change Configuration Data
One way to change the configuration data for a 1794 FLEX I/O module:
1. Enter the new configuration data (#:C) into the controller tags.
2. Select Module or Adapter in the I/O configuration tree.
3. Right-click Properties.
When your first add an I/O module to the I/O
configuration, the default parameters are assigned. To change
these default values, you must modify the controller reference
tags associated with the I/O module. To download the new
configuration, you must reinitiate the connection to the I/O
module. This download is best achieved by inhibiting and
uninhibiting the module.
