4.4.2. Network plan
Before the network is installed and programmed, it is recommended to create a plan of the FSoE
network.
The following steps are necessary to create the plan of the FSoE network:
•
Determination of the FSoE Master and of its directly connected elements (e. g. IOs,
encoder)
•
Determination of the
EtherCAT Master (-> SCU)
•
Determination of the
EtherCAT Slaves
•
Determination of the structure of the FSoE network
(The structure of the FSoE network is equal to the structure of the EtherCAT
network.)
•
Determination of the network parameters
o
Module adress (freely selectable, unambiguous status number in the network)
o
Cycle time (corresponding to the slowest assembly in the network)
o
Adresses (Master = 0, Slave x
–
consecutively numbered)
o
Connection ID (freely selectable, unambiguous status number in the protocol-
determines the communication sequence)
After the network structure and its parameters have been determined, the network can be
programmed via SafePLC
2
.
To program the network, the programming manual SafePLC
2
must be used or considered.
Below, only those steps supplementary to the SafePLC
2
programming manual are described that
are necessary considering the SafePLC²programming manual to map the network in the program
SafePLC
2
, and to program the modules Master SCU and Slaves (SDU,
SSB,…) –
also those
produced by external companies.
For parameter determination, please also use the module data files,
the ratings’ data files and the
specifications of the manufacturer.
NOTICE:
Incorrectly assigned or incorrectly set parameters can cause network malfunctions (e. g. loss of
input data or delay of input data).
WARNING
Malfunctions of the FSoE network can cause loss or impairment of safety functions.
