The only valid mappings for ControlLogix outputs are to PROFIBUS
inputs on active nodes.
Rules for entries:
• can be an input on an active slave
• can’t be an output on an active slave
• can’t be an input or an output on a monitored slave
The ControlLogix connection run/idle header can also be mapped to an
output register. The mapping has the keyword Run in the offset field.
The value is 1 if the ControlLogix is in run mode and 0 if it is in program
mode.
Status Input Data
The status input data section begins with a line that starts with the
keyword StatusInput.
This is followed by up to 64 mappings, of the form
offset (optional), PROFIBUS node number, PROFIBUS data area and
offset, item count, data type, ControlLogix tag name
For example,
, 2, O/7, 1, U8, Node2Output
is a mapping that takes 1 byte of the PROFIBUS output data for node 2,
starting from byte offset 7. The data type is U8. It is assigned tag name
Node2Output in the ControlLogix.
Rules for entries:
• can’t be an input on an active slave
• can be an output on an active slave
• can be an input or an output on a monitored slave
Sample File
The following sample file shows how data could be mapped for an AN-X
configured with PROFIBUS nodes 1 and 2 as active nodes and node 3 as
a monitored node on the same network.
