Chapter 6 Communication and Networking
S5 has limited capacity for connecting large amounts of I/O to controllers as
shown in the following table.
S5 Network
Communication
S5 has a low-performance Local Area Network (LAN) called SINEC L1 that
operates at 9600 bps and uses the CP 530 communication module. There is
also a S5 high-performance LAN called SINEC H1 that operates at 10 Mbps
and uses the CP 143 network communication module.
CP 530 Network Communication Module
The CP 530 Network Communication Module is used to interconnect S5 PLC
networks to achieve a distributed and hierarchical automation LAN. It
executes all the central control functions of the LAN.
The SINEC L1 LAN operates in a master/slave configuration. The master S5
controller must contain a CP530 module and the slave S5 controller may
communicate via the controller programming port or via a CP530 module
depending on the model of the slave controller.
The Master coordinates and monitors the entire data traffic in the SINEC L1
network, as well as routing through and monitoring of programming functions
via the bus. The other programmable controllers participating in the network
are automatically designated the slave controllers. These are two ways of
sending data packets in the SINEC L1 network:
From any SINEC L1 node to another
From any SINEC L1 node simultaneously to all other nodes connected
(broadcasting)
The data contained in the data packet may be the status of inputs, outputs, and
flags or the contents of data words.
