FP_MEWNET_CLEAR_ERRORS

Clear errors in the FP7 multi-wire link unit

This FP instruction clears errors in the FP7 multi-wire link unit. It resets the values of the following system variables:

System variable	Description
`sys_bIsMultiWireUnit1Error`	Error in FP7 multi-wire link unit 1
`sys_bIsMultiWireUnit2Error`	Error in FP7 multi-wire link unit 2
`sys_bIsMultiWireUnit3Error`	Error in FP7 multi-wire link unit 3
`sys_bIsMultiWireUnit4Error`	Error in FP7 multi-wire link unit 4
`sys_bIsMultiWireUnit5Error`	Error in FP7 multi-wire link unit 5
`sys_bIsMultiWireUnit6Error`	Error in FP7 multi-wire link unit 6
`sys_wMultiWireUnit1ErrorCode`	FP7 multi-wire link unit 1 error (higher byte: error code, lower byte: unit number)
`sys_wMultiWireUnit2ErrorCode`	FP7 multi-wire link unit 2 error (higher byte: error code, lower byte: unit number)
`sys_wMultiWireUnit3ErrorCode`	FP7 multi-wire link unit 3 error (higher byte: error code, lower byte: unit number)
`sys_wMultiWireUnit4ErrorCode`	FP7 multi-wire link unit 4 error (higher byte: error code, lower byte: unit number)
`sys_wMultiWireUnit5ErrorCode`	FP7 multi-wire link unit 5 error (higher byte: error code, lower byte: unit number)
`sys_wMultiWireUnit6ErrorCode`	FP7 multi-wire link unit 6 error (higher byte: error code, lower byte: unit number)

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;
	END_VAR

LD body

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