MX_AI_Max_Reset

UINT32 MX_AI_Max_Reset(UINT32 slot, UINT32 start, UINT32 count);

Sets max raw and engineering values to be current values for appointed AI channels.

Input Parameters

slot

Slot index of the AI module (zero based). For ioLogik W5348, the slot index is always “0”

start

The first queried AI channel (zero based)

count

The number of queried AI channels

Return Value

MX_AI_Range_Signed

UINT32 MX_AI_Range_Signed(UINT32 range);

Checks if the readings of an AI channel is a positive value or contains positive and negative values.

Input Parameters

range

Return Value

TRUE (positive and negative) or FALSE (positive only).

Notes

ioLogik W5348-C series only

MX_AI_BurnOut_Value_Set

UINT32 MX_AI_BurnOut_Value_Set(UINT32 slot, UINT32 start, UINT32 count, float *buf);

To set the current burn-out value of the AI channels (this function is only available in the module RM-3802-

and only within an AI range of 4-20mA)

Input Parameters

slot

Slot index of the AI module (zero based)

start

count

buf

Return Value

To get the complete IO_ERR code list, please refer to the header file libmoxa_pgm.h.

Notes

This function can only be used for the ioPAC RM-3802-T AI module.

The burn-out value is only applied while the AI channel range is set to 4-20mA.

The valid burn out value is 0.0-4.0 mA

If the AI channel range is set to 0-20mA, the burn-out value will not be applied.
