FP_MEWNET_W2_SET_STATION_NUMBER

Set MEWNET-W2 station number

This FP instruction sets the MEWNET-W2 station number for the MEWNET-W2 unit in the slot number specified by s1_Slot.

Input

s1_Slot (ANY16)

Slot number of expansion unit

s2_StationNumber (ANY16)

Station number (setting range: 1–64)

The station number can be changed only when the rotary switch on the front panel of the unit is set to 0.

Output

d_Result ((ANY16))

Starting address of the memory area in the master unit that stores the processing result (1 word)

Content of the processing result d_Result

(1) Bit 15: Process-in-progress flag
FALSE: Process is completed

TRUE: Process is in progress
(2) Bit 14: Execution result flag
FALSE: Normal completion

TRUE: Abnormal completion
(3) Lower byte: Execution result code
- 0: Normal completion
- 1: The specified communication port is invalid
- 2: Setting error
- 3: Mode change error
- 4: The specified communication port is occupied
- 5: Inconsistency of parameters to be changed (at the start/end of the setting process, parameters specified by operands are inconsistent)
- 7: Unit number setting on the front panel of the multi-wire link unit (when the rotary switch is not set to 0)

Remarks

Before you execute the instruction, make sure that the bit 15 (process in-progress flag) of the processing result storage area specified by dResult is FALSE.
The processing result is stored in the area specified by d_Result.If an error occurs, the execution result flag (bit 14) is turned to TRUE. The error code is stored in lower bytes of d_Result.

Example

POU header

All input and output variables used for programming this function have been declared in the POU header.The same POU header is used for all programming languages.

	VAR
		bEnable: BOOL:=FALSE;
		iSlot: INT:=0;
		wResult: WORD:=0;
		iStationNumber: INT:=0;
	END_VAR

LD body

When the variable bEnable is set to TRUE, the function is executed.
