Communication via Modbus:
Modbus RTU (Remote Terminal Unit) is a standard protocol for network communication and
uses the electrical RS485 connection for serial data transmission between Modbus devices
in the network.
Modbus RTU uses a master/slave network in which the entire communication is triggered by
only one master device while the slaves can only respond to the request of the master. The
master sends a request to a slave address and only this slave address responds to the
command (exception: broadcast frames to slave address 0 that are not acknowledged by the
slaves).
SIMOCODE pro V Modbus devices have been developed in accordance with the "MODBUS
over serial line specification and implementation guide" (available at www.modbus.org
)). You can find the relevant information on establishing Modbus
RTU communication in this specification. The key points for a Modbus RTU communication
network ("Multipoint System requirements") listed in the specification apply equally for a
communication network with SIMOCODE devices.

Communication via EtherNet/IP:
EtherNet/IP (EtherNet Industrial Protocol, often simply called EIP) is a real-time Ethernet that
is used mainly in automation engineering. EtherNet/IP was developed by Allen-Bradley and
was later handed over to the Open DeviceNet Vendor Association (ODVA) as an open
standard. See Open DeviceNet Vendor Association (
Besides PROFINET and Modbus/TCP, EtherNet/IP is an Ethernet-based fieldbus that is
currently widely spread.
SIMOCODE pro V EtherNet/IP devices were developed in compliance with the EtherNet/IP
standard and have the following properties:
●
Integrated switch with two ports
●
Media redundancy via Device Level Ring (DLR)
●
System redundancy (as of E03).
