DirectLOGIC MODBUS Port Configuration for DL05, D2-250(-1), or D4-450
The following configuration example is specific to the D2-250(-1) and DL05.
Refer to the appropriate CPU User Manual for the specifics on your DirectLogic
CPU.
• In DirectSOFT, choose the PLC menu, then Setup, then “Secondary Comm Port”.
• From the Port list box, choose “Port 2”.
• For the Protocol, select ONLY “MODBUS”. (Do not select multiple protocols.)
• In the Timeout list box, select “800 ms”.
• Response Delay Time should be “0ms”.
• The Station Number should be set to “1” to make the D2-250(-1) or DL05 CPU a
MODBUS Master.
• The Baud Rate should be set at “9600” (or higher, if using an FA-ISOCON network
adapter module).
• In the Stop Bits list box, choose “1”.
• In the Parity list box, choose “Odd”.
The DL250 network instructions used in Master mode will access only slaves 1 to 90.
