Configuration
The configuration is carried out in the PLC configuration of the
easy Soft CoDeSys programming software. The network module is
entered as an expansion device in the configuration tree. This
contains predefined input and output channels (R1…R8, S1…S4)
for the cyclical transfer of data.
Setting the station address
The EASY205-ASI is assigned a station address with an external
programming device.
EASY221-CO, EASY204-DP, EASY222-DN
The procedure for data exchange between the EASY network
modules and a master is described in detail in separate manuals,
a table 21.
Cyclic data exchange
The EASY204-DP, EASY221-CO, EASY222-DN network modules
have the same cyclical data exchange procedure.
The master exchanges 3 bytes of data in each direction with the
network modules connected to the EC4-200.
From the point of view of the master, this data is written to the
EC4-200.
From the point of view of the master, this data is read from the
EC4-200.
