1.7.2 Modnet 1/SFB Communication
Modicon A500 can communicate with other devices via the BIK 151 / BIK 812 as a
master or slave on the Modnet 1/SFB (see Figure 8). 1N and DEA logs can be run via
this bus. The interface used for the communication is an RS 485 interface which is lo-
catedontheBIK.
A120 (Slave) A350 (Slave) Slave
A500 (Master)
To other bus nodes via 1N and/or
DEA procedures
Figure 8 Example of a communication between A500 (Master) and A350 and A120 (Slaves)
The Following is Possible as a Master:
BIK 151 or BIK 812 interface module in an A500
BIK 151 interface module in an A350
The Following is Possible as Slaves:
BIK 151 or BIK 812 interface module in an A500
BIK 151 interface module in an A350
ALU 202 in an A120
I/O bus link to DEA 106, DEA 116
I/O bus link to DEA-H1, DEA-K1
The following configuration limits are valid for the Modnet 1/SFB communication:
4 BIK modules per A350/A500, including max. 3 for 1N procedures
28 slaves per master (BIK ...), including max. 16 I/O bus links (DEA ....)
More detailled information can be found in the module descriptions of the interface
modules (ALU 202, BIK 151, BIK 812).
