Combinations.
Application
A Magelis operator dialogue terminal can be connected directly to a Modicon STB
island via the Modbus programming port on the island's standard communication
module.
1 PLC.
2 Modicon STB distributed I/O island with STBN21 standard NIM
communication module.
3 Modbus serial cable and adaptor if required
(see compatibility table on page 101).
4 Magelis operator dialogue terminal.
Functions
In this architecture, the Magelis operator dialogue terminal is the Modbus serial link
master and the Modicon STB standard communication module is the slave.
The connection allows:
Data exchange between the Magelis terminal and the PLC, via the exchange
area dened by the user in the Modicon STB memory.
Two word tables have to be congured (sizes, labels) in the memory of the NIM
communication module, using the Modicon STBSPU1 conguration
software:
One written by the terminal and read by the PLC (HMI->PLC)
The other written by the PLC and read by the terminal (PLC->HMI)
The Modicon STB distributed I/O island is used as a neutral gateway between
the PLC and the terminal.
The terminal can display information coming from the PLC and, conversely,
control automatic functions in the normal way.
Display of the following Modicon STB island data on the screen of the Magelis
terminal:
Input and output values
Internal states
When the Modicon STB island is in "Online test" mode (communication with the
PLC operational), writing of the island's output values. This mode can be
accessed by entering a congurable password.
4
When the Modicon STB island is in "PLC ofine test" mode (communication with
the PLC stopped), writing of the island's output values. This mode can be
protected by a congurable password, if the user requires.
