6. If you choose to read and write the bit register of the slave, the %MW and %QW registers of the local

device can be regarded as the storage registers for reading and writing data. The ranges of the

storage register are %MW0~%MW32767 and %QW0~%QW63. If the ranges are exceeded or other

7. The set parameter values of this instruction are only valid during the operation of the PLC. When the

motion controller is repowered after power off, the parameters configured before the power off are all

invalidated. The ETH_Link_Config instruction must be re-executed if the configuration before the

power off is needed to use.

8. When the bit registers of the slave are read, the value of Read_FunCode must be set to 01 or 02.

You can select the function code according to the type of the bit register through referring to the

corresponding module manual.

9. Set the communication mode via the input parameter Noncyclic. The communication mode is the

cyclic communication mode if Noncyclic is set to FALSE. The communication mode is the non-cyclic

communication mode if Noncyclic is set to TRUE.

a. Cyclic Communication Mode: When the current Link is set as cyclic communication mode. The

configuration for the Link will be effective immediately and the data exchange between the

master and slave will be conducted cyclically after RS485 communication function is enabled

via RS485_Link_Manage instruction.

The configuration for the link will not be executed and the data exchange with the slave will stop

after RS485 communication function is disabled via RS485_Link_Manage instruction.

b. Non-Cyclic Communication Mode: When the current Link is set as non-cyclic communication

mode. The configuration for the Link will be effective immediately and the data exchange

between the master and slave will be conducted only once after RS485 communication function

is enabled via RS485_Link_Manage instruction.

If the data exchange between the master and the slave is to be made once again, re-enable

RS485 communication function after RS485 communication function is disabled via

RS485_Link_Manage instruction.
