Accessing the common area of the BASIC and CPU modules

To access the common area of a BASIC CPU module (such as F3BP20), specify as follows:

 

Common area word access

Specify the device as "Dxxxx". "D0001" indicates the beginning of the common area, and one device is one word. For integer type tags, one device is assigned to one tag.

 

Common area bit access

Specify the device as "Ixxxx". "I0001" indicates the beginning of the common area, and 1 device is 1 bit. For integer type tags, 16 devices are assigned to one tag.

Waiting time
Response timeout from PLC.

 

Retry count
When a communication error occurs, the system will retry the specified number of times.

 

protocol
Select UDP or TCP.

 

Share the PC port number with other PLCs
In the case of this PLC, this has no particular meaning.

 

Other detailed settings

c_plc_0281

 

Minimum Communication Interval
Specifies the waiting time on the PC side after receiving a device value from PLC and before the next transmission.
