SymCom CIO-777-PR Operating instructions

BE SURE POWER IS DISCONNECTED PRIOR TO INSTALLATION!
FOLLOW NATIONAL, STATE AND LOCAL CODES.
READ THESE INSTRUCTIONS ENTIRELY BEFORE INSTALLATION.
The CIO-777-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 design of the CIO-777-PR provides the following benefits in both new and existing installations:
reduced field wiring
greater operator efficiency
ease in system startup and commissioning
The CIO-777-PR Profibus module can be DIN rail mounted, or mounted directly to a back panel. The
CIO-777-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-777-PR Module is compatible with SymCom’s Model 777-P Series overload relays. It simply
connects to the side of the 777-P Series and permits remote monitoring and control of the 777-P
Series unit over a Profibus network.
CONNECTIONS
1. Mount the CIO-777-PR in a convenient location in a properly rated enclosure. The CIO-777-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-777-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 that communication is established between the CIO-777-PR and the
Profibus master, and OLC LED indicates communication is established with the 777-P Series
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 LEDs 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 a 777-P
Series overload relay.
OPERATION
The CIO-777-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, under or around sharp edges.
Avoid sources of electrical interference that can induce noise into the cable. Use the maximum
practical separation from such sources.
Maintain a minimum separation of 3.3 ft. (1m) from the following equipment:
oair conditioners and large blowers
oelevators and escalators
oradios and televisions
ointercom and security systems
ofluorescent, incandescent, and neon lighting fixtures
Maintain a minimum separation of 10 ft. (3m) from the following equipment:
oLine and motor power wiring
oTransformers
oGenerators
oAlternators
Terminating Resistors
Profibus segments must be bus terminated as shown.
