In the context of EPLAN, a "bus port" is a shorthand term for PLC (Programmable Logic Controller) connection points specifically configured for network or bus connections.
Here's a more detailed explanation:
-
PLC Connection Points: These are points on a PLC where connections to external devices (sensors, actuators, other PLCs, etc.) are made.
-
Function Definition: In EPLAN, each connection point is defined by a function definition. This definition determines the connection point's properties and behavior.
-
Category "Network / Bus Cable Connection": Bus ports in EPLAN are defined with function definitions that fall under this category. This indicates that they are designed for network or bus communication.
-
Net-Connecting and Signal-Transmitting: By default, bus ports are designed to connect to a network (making them net-connecting) and transmit signals across that network (making them signal-transmitting).
-
Purpose: The primary purpose of a bus port is to facilitate the planning and documentation of bus and network connections within an EPLAN project. They allow engineers to visually represent and manage complex network topologies.
In essence, a bus port in EPLAN represents a physical or logical point on a PLC specifically designated for network communication, allowing for the structured planning and documentation of those connections.
