This term:
Means:
Connection
A communication mechanism from the controller to another
module in the control system
ControlBus
The backplane used by the 1756 chassis
Data consumer
In the producer/consumer model, a device that consumes data.
For example, an output module consumer output data from the
owner-controller.
Direct connection
An individual I/O connection established between the
owner-controller and an I/O module
Electronic keying
A feature where modules can be requested to perform an
electronic check to make sure that the physical module is
consistent with what was configured by the software
Field side
Interface between user field wiring and I/O module
Listen-only connection
An I/O connection where another controller owns/provides the
configuration and any output data for the module. The listener
merely connects and receives the data broadcast by the
module. An owner-controller must exist to allow a listener.
Major revision
A module revision that is updated any time there is a
significant functional change to the module resulting in an
interface change with software
Messaging
The method used communicate configuration, input and output
data between the controller and a PLS module
Minor revision
A module revision that is updated any time there is a change to
the module that does not affect its function or software
user interface
Module-defined
data types
Data types used for configuration in RSLogix 5000 that the
module itself creates
Network Update Time
(NUT)
The smallest repetitive time interval in which data can be sent
on a ControlNet network. The NUT ranges from 2ms to 100ms
Removable terminal
block (RTB)
Field wiring connector for I/O modules
Removal and Insertion
Under Power (RIUP)
A ControlLogix feature that allows a user to install or remove a
module or RTB while power is applied.
Requested Packet
Interval (RPI)
The maximum amount of time between broadcasts of I/O data
for a specific connection
RSLogix 5000™
ControlLogix programming software
Service
A system feature that is performed on user demand
System side
Backplane side of the interface to the I/O module
User-defined data types
Data types used for configuration in RSLogix 5000 that the
user must creates

enter the Main Routine
Rung 0 is an unconditional “jump to subroutine”. It directs the program scan through
the “Pls Read/Write Request” program. This subroutine checks the “request read/write
word” and also sets the “permit” bits for the corresponding message to be sent.
Click here to access the
configuration message
instruction for this rung.
IMPORTANT: Message
instructions are
explained on page 5-18.
Rung 1 uses the PLS Axis Configuration Message to write
configuration for each of the PLS module’s 20 outputs. You
must set the “Request Read/Write”, and when the ladder
code determines it is time to send the message, it will set
the appropriate “Permit Read/Write” bit.
Rung 2 uses the PLS Limit Switch message to write
configuration for each of the PLS module’s 20 outputs.
You must set the “Request Read/Write”, and when the
ladder code determines it is time to send the message,
it sets the appropriate “Permit Read/Write” bit.
Rung 3 uses the Offset Data message to read the PLS
module offset values. You must set the “Request Read/
Write”, and when the ladder code determines it is time
to send the message, it sets the appropriate “Permit
Read/Write bit.
Rungs 4 and 5 are shown on the next page.

Rung 4 uses the PLS Input Registration message to
update PLS module registration information. You must
set the “Request Read/Write”, and when the ladder
code determines it is time to send the message, it sets
the appropriate “Permit Read/Write bit.
Rung 4 writes a bit that is set when any of the CIP
Generic messages have an error bit set.
IMPORTANT: You must use the error bits to perform an
orderly shutdown or any other necessary procedure. You
must modify the logic to support any error sequences
that are required. When a message contains an error,
the message is not reattempted. In this case, all
messaging to the PLS module will stop. You must
handle the error and then clear the error bit.
