Execute
The instruction is
executed when

TRUE.
BOOL
TRUE or FALSE

CycleTime
The cycle time the master
sends MODBUS TCP
data.

FALSE to TRUE.
LinkKeeptime

When Execute
changes from
FALSE to TRUE.
Note:
1. Every element of the values in CycleTime and LinkKeeptime corresponds to the number in a
ETH_Link_Config instruction. For example, the first element of CycleTime value corresponds to the
data-sending cycle time of the number 1.
2. The unit of CycleTime is milliseconds (ms) and LinkKeepTime is seconds (s).
3. LinkKeeptime is the link duration (unit:seconds). If there is no data exchange between the master and
slave within the time specified by LinkKeeptime, , the controller will disconnect the link to the slave
automatically.

Function
When the MODBUS TCP master function of the controller is used, ETH_Link_Config_Ext can be used
to set the cycle time and link duration for MODBUS TCP data exchange. The firmware of V1.01 and
above supports the function.
1. The ETH_Link_Config_Ext instruction can be used to set the cycle time and link duration for MODBUS
TCP data exchange. The instructon can also be used in the configuration of MODBUS TCP parameters.
And it can still be used in the MODBUS TCP master function of the controller. One piece of MODBUS
TCP data sending is finished and then another piece will be sent out immediately. The link duration is
