acquired with the dynamic IP method or when it is in a more complicated
network environment and the IP is difficult to acquire. Please refer to Chapter 8
for detailed operation contents.
Chapter 2 PLC and CBEH Communication Interfaces
The communication interface between the PLC module and the CBEH
communication module is via the CPU registers D3950~D3999. The functions for
each register in this area are described as follows:
Active call back and initialization setting command code
Execute active call back, value zero must be
entered when terminating connection.
Reset CBEH module. When the local machine’s
internet parameter is changed, it can reset
without powering off; will be changed to zero
after the command is executed.
Resets the CBEH module to factory settings.
Will be changed to zero after the command is
executed.
Internet Clock Synchronization
Set whether to use daylight saving time now
0 – Standard time
1 – Daylight saving time
Second, time value data range 0~59
Minute, time value data range 0~59
Hour, time value data range 0~23
Day, time value data range 1~31
Month, time value data range 1~12
Year, time value data range 0~99
Week, time value data range 0~6
Update flag. NTP Calendar updates once every
ten minutes; the flag value increases by 1 after
every update. Synchronization time can be
determined by detecting the changes of this flag.
Note
*1
: The values in this table is written by the CPU. For register ranges D3978~D3989 and
D3991~D3999, only D3990 is written by the CPU during 0x4951, all others are written by the CBEH.
