A-B 1756-IA16I Module Rockwell ControlLogix Input Module

Common Industrial Protocol

(CIP) CIP™ is a messaging protocol for devices in industrial automation control systems. 

CIP is the application layer for the EtherNet/IP network. 

This protocol implements a relative path to send a message from the producing modules in a system to the consuming modules. 

CIP uses the Producer/Consumer networking model instead of a source/ destination (Primary/Secondary) model. 

The Producer/Consumer model reduces network traffic and increases speed of transmission. 

In traditional I/O systems, controllers poll input modules to obtain their input status. 

In the CIP system, digital input modules are not polled by a controller. 

Instead, they produce their data either upon a change of state (COS) or at a requested packet interval (RPI).

The frequency of update depends upon the options that are chosen during configuration and where on the network the input module resides. 

The input module, therefore, is a producer of input data and the controller is a consumer of the data. 

The controller can also produce data for other controllers to consume.

The produced and consumed data is accessible by multiple controllers over the Logix backplane and over the EtherNet/IP network. 

This data exchange conforms to the Producer/Consumer model.

Installing the Motor 

The S-Series and MTR-Series servo motors are designed for either vertical or horizontal

mounting and have a protection rating of IP65 (not including the connectors and shaft). 

The motors should be mounted in a location where the environmental conditions

are within the specifications stated in Chapter 2. Use the following guidelines when mounting the motors: 

• Observe the shaft radial and thrust load limits. Loads exceeding these limits will cause premature failure of the motor. 

Excessive belt tension could cause bearing or shaft failure. 

• Be sure to ground the motor using the ground wire in the motor power cable. 

• Ensure that the motor cables are free from excessive stress, stretching, pinching or bending. 

• To avoid damage, do not carry a motor by holding the cables or shaft. 

• Do not apply excessive axial force or impact loads when installing the motor coupling or shaft pulley, or the encoder may be damaged. 

• Install the motor in a location free from corrosive contaminants, dust, excessive water spray, or combustible gas. 

• The shaft of the S-series servo motor is treated with grease (Shell Oil Alvania No. 2) for corrosion protection during storage.

Consider the effect of the grease on any plastic parts that are mated with the shaft. 

• The optional servo motor brake should be used for holding stationary loads only. 

Do not use this brake to stop a moving load, or reduced life or damage to the brake may occur. 

Apply this brake only after the motor is stopped.
