CR#114: Modbus TCP Time-Out
Explanations:
Setting up the communication time-out (in ms) for Modbus TCP mode.
CR#115: Modbus TCP Trigger
Explanations:
When the CR value is set as “1”, Modbus TCP will be triggered. After the data transmission is
completed in Modbus TCP mode, the CR value will automatically be reset to “0”. Please trigger
by differential instructions.
CR#116: Modbus TCP Status
Explanations:
Displaying the current communication status of Modbus TCP mode. When the CR value is set
as”0” Æ the data have not yet been received; when the CR value is set as “1” Æ the data
exchange is in progress; when the CR value is set as “2” Æ the data exchange is successful;
when the CR value is set as “3” Æ the data exchange fails.
CR value Data exchange status
0 The data have not been received.
1 The data exchange is in progress.
2 The data exchange is successful.
3 The data exchange fails.
CR#117, 118: Modbus TCP Destination IP

Setting up the destination IP address in Modbus TCP mode. See explanations on CR#70 and
#71 for how to set.
CR#119: Modbus TCP Data Length
Explanations:
Setting up the length of communication data in Modbus TCP mode. Length for 8-bit mode: K1
~K100; length for 16-bit mode: K1 ~ K200.
CR#120 ~ 219: Modbus TCP Data Buffer
Explanations:
Buffer for transmitted/received data in Modbus TCP mode.
