10.4 User - defined Communication Example
10.4.1 User-defined communication example system configuration
When communication with device of which protocol is not supported by Cnet I/F module client, how
to use user-defined communication is described in the system like [Figure 10.4.1] below
• System configuration
[Figure 10.4.1] User defined communication system configuration
At this example, Cnet I/F module and partner device to communicate through user defined communication
system configuration are as [Table 10.4.1].
Device name
Main unit XBC-DN32H
Han-Young temperature controller
PX7
*Note2)
Built-in RS-485
Operation mode Client Server
Protocol User frame definition PC Link
9,600 9,600
Data bit 8 8
Stop bit 1 1
Parity bit None None
Station no. 0 1
Delay time
Reads present value and setting value from temperature controller every
second and saves present value at MB200 and setting value at MB210.
[Table 10.4.1] User defined communication system configuration
Note1) Delay time is set to prevent from frame error when communication with device of which response
is slow in case of RS-422/485 communication. It varies according to partner device and it has
50~100ms value generally.
