Function
ETH_ SetServerlinkkeeptime is used to set the link duration as the controller serves as the MODBUS
TCP slave.
1. The ServerLinkKeeptime value is valid only when the controller works as the MODBUS TCP slave.
When the controller works as the MKODBUS TCP master, the execution of the ETH_
SetServerlinkkeeptime instruction will have no impact on the MODBUS TCP master function.
2. If there is no data exchange between the controller slave and the master within the time specified by
ServerLinkKeeptime, the controller slave will disconnect the link to the MODBUS TCP master
automatically.
3. The instruction can only set the link duration of the MODBUS TCP slave which the LAN2 port of the
motion controller works as.
