changes to TRUE as Open changes from FALSE to TRUE. When Enable changes from TRUE
to FALSE, Valid and LinkOpened change to FALSE.
Case 3： As Open is TRUE and Enable changes from FALSE to TRUE, Valid and LinkOpened change
to TRUE. As Open changes to FALSE, LinkOpened changes to FALSE.
Function:
RS485_Link_Manage is used to enable or disable the RS485 communication. The firmware of V1.01
and above supports the function.
1. The input Enable is used to control the instruction to take effect or not. When Enable changes to
FALSE, the operation of other parameters of the instruction will be invalid. When Enable changes
to TRUE, the instruction will take effect and then the operation of other parameter of the instruction
will be valid.
2. In the case that Enable is TRUE, the RS485 communication is switched on as Open changes to
TRUE. The RS485 communication is switched off as Open is FALSE.
3. Before the RS485 communication function is switched on, the parameters of the
RS485_Link_Config instruction must have been configured.
Otherwise, the configured parameters will be not effective if the RS485 function is switched on
before the parameters of the RS485_Link_Config instruction are configured, unless the RS485
communication function is re-switched on.
4. After multiple LinkNum parameters are configured through RS485_Link_Config instructions, only
one RS485_Link_Manage instruction is enough to switch on the RS485 communication function.
And all configurations specified by RS485_Link_Config instructions are for the exchange data with
the slave.
