CIO-MLPII-PR

P1-P3P4-P6P7-P9P10-P12
BE SURE POWER IS DISCONNECTED PRIOR TO INSTALLATION!
FOLLOW NATIONAL, STATE AND LOCAL CODES.
READ THESE INSTRUCTIONS ENTIRELY BEFORE INSTALLATION.
The CIO-MLPII-PR Module is a convenient and cost-effective Profibus interface capable of providing
discrete control and monitoring of motor starters, drives, and other devices over a Profibus network.
The CIO-MLPII-PR is designed to provide the following benefits in both new and existing
installations:
§ reduced field wiring
§ greater operator efficiency
§ ease in system startup and commissioning
The CIO-MLPII-PR Profibus module can be DIN rail mounted, or mounted directly to a back panel.
The CIO-MLPII-PR’s compact size, ease of wiring and Profibus communications capability makes the
use of traditional discrete devices on Profibus cost-effective and simple.
The CIO-MLPII-PR Module is compatible with Square D’s Model MLPII overload relay. It simply
connects to the side of the MLPII and permits remote monitoring and control of the MLPII over a
Profibus network.
CONNECTIONS
1. Mount the CIO-MLPII-PR in a convenient location in a properly rated enclosure. The CIO-MLPII-
PR can be mounted to a back panel using screws or can be snapped onto DIN rail.
2. Connect the five Profibus wires to the 5-pin connector on the front of the CIO-MLPII-PR Module.
24VDC should be connected to V+ and V-. Connect the other three wires to A, B and Shield.
3. The PBus LED indicates communication is established between the CIO-MLPII-PR and the
Profibus master, and OLC indicates communication is established with the MLPII overload.
4. Connect the Profibus SUB-D connector to the Profibus network.

DIAGNOSTIC INDICATOR LIGHTS
The unit is energized when power is applied between V+ and V- on the connector. The PBus and
OLC lights will flash until communication is established. The PBus communication status indicator
light will come on steady when a Profibus master is communicating with the unit. The OLC
communications status indicator light will come on steady when it is communicating to an MLPII
overload relay.
OPERATION
The CIO-MLPII-PR Module is a DP-V0 device. Cyclical I/O is supported for the transfer of input and
output information.
PROFIBUS NETWORK CONFIGURATION
Cable Routing
Follow these general cable-routing guidelines:
• Avoid areas of high temperature, moisture, vibration, or other mechanical stress.
• Secure the cable where necessary to prevent damage.
• Use cable ducts, raceways, or other structures to protect the cable.
• Never route cables over or around sharp edges.
• Avoid sources of electrical interference that can induce noise into the cable. Use the maximum
practicable separation from such sources.
• Maintain a minimum separation of 3.3 ft. (1m) from the following equipment:
o air conditioners and large blowers
o elevators and escalators
o radios and televisions
o intercom and security systems
o fluorescent, incandescent, and neon lighting fixtures
• Maintain a minimum separation of 10 ft. (3m) from the following equipment:
o Line and motor power wiring
o Transformers
o Generators
o Alternators
Terminating Resistors
Profibus segments must be bus terminated as shown.
