F650 Signal Type; Communications Architecture - GE F650 User Manual

CHAPTER 1: GETTING STARTED

1.2.2.2 F650 signal type

Contact Inputs/Outputs: Digital signals.
CT and VT inputs: Signals coming from the inputs of current and voltage transformers, used for monitoring the power
system signals.
Remote CAN Bus Inputs/Outputs: Signals associated with physical input/output contacts from a Remote Digital Input/
Output Module (CIO) connected to the 650 unit via the CAN Bus existing in options X, Y, Z, C and M for rear serial
communication board 1.
PLC: Programmable Logic Controller. Control module that enables the unit configuration (assignment of inputs/outputs)
and the implementation of logic circuits.
Protection Elements: Relay protection elements, for example: Overcurrent, overvoltage, etc.
Remote inputs and outputs: Provide a means of sharing digital point state information between remote devices using IEC
61850 GSSE and GOOSE messages.
Analog Inputs: Signals associated with transducers.

1.2.3 Communications architecture

A dedicated serial port is used for communication between the main processor and the human-machine interface. The
serial connection provides immunity against electromagnetic disturbances, thus increasing system safety.
All 650 units incorporate one RS232 (USB or DB9)serial port on the front of the relay. They can also incorporate up to two
additional communication modules on the rear.
One of the modules provides asynchronous serial communications, using different physical media (RS485 + cable remote
CAN bus I/O, plastic or glass fiber optic) depending on the selected model. The module incorporates two identical ports,
COM1 and COM2. The COM2 port is multiplexed with the front port. Additionally, this module may incorporate a port for
CAN bus communications, used for the connection to the remote CAN Bus I/O module. This feature increases the I/O
capability by up to 100% if the maximum number of I/Os available inside the relay is not enough for a specific application.
Available options are:

F Without additional communication ports
A Two RS485 ports
P Two Plastic F.O. ports
G Two Glass F.O. ports
X Two RS485 ports and a CAN port for remote CAN bus Inputs/Outputs
Y Two Plastic F.O. ports and a CAN port for remote CAN bus Inputs/Outputs (fiber)
Z Two Glass F.O. ports and a CAN port for remote CAN bus Inputs/Outputs (fiber)
C CAN port for remote CAN Bus I/O (cable)
M RS485 + RS485 port and a CAN port for remote CAN Bus I/O (cable)
The other module provides Ethernet communications (ETH Port), using 10/100BaseTX (self-negotiable speed) or 100BaseFX
connectors, depending on the selected model. The most complete models include a double redundant 100BaseFX fiber
optic port. Redundancy is provided at the physical level, for options D and E; the unit incorporates internally duplicated
and independent controllers for extended system reliability and accessibility.
