Description

(6) Specify Word [signed], Double Word [signed], or Single-precision real number as the data type of input array data, the

subtraction value, and output array data in i_uDataType (data type selection).

(7) Specify the number of data points for an array where the subtraction is performed in i_udSize (number of data points).

When 1: Double Word [signed] or 2: Single-precision real number is specified by i_uDataType (data type selection), file

(8) It takes multiple scans until the subtraction is completed. When the input array data before the operation is changed

during the operation processing, the operation processing is executed with the changed data. The number of points with

the operation completed is output to o_udOutAryNum (number of output data points). When the subtraction is completed,

o_bOK (normal completion) turns on.

(9) If a value out of the range is set in i_udSize (number of data points), o_bErr (error completion) turns on and the

processing of the FB is interrupted. In addition, 105H is stored in o_uErrId (error code). For the error code, refer to the list

of error codes. ( Page 15 List of error codes)

(10)If a value out of the range is set in i_uDataType (data type selection), o_bErr (error completion) turns on and the

processing of the FB is interrupted. In addition, 103H is stored in o_uErrId (error code). For the error code, refer to the list

of error codes. ( Page 15 List of error codes)

(11)When a single-precision real number is set in i_uDataType (data type selection) and the value stored in the file register

(ZR) is not a single-precision real number, o_bErr (error completion) turns on and the processing of the FB is interrupted.

In addition, 200H is stored in o_uErrId (error code). For the error code, refer to the list of error codes. ( Page 15 List

of error codes)

(12)If i_bEN (execution command) is turned off before o_bOK (normal completion) or o_bErr (error completion) turns on,

o_bErr (error completion) turns on in one scan. In addition, 205H is stored in o_uErrId (error code) in one scan. For the

error code, refer to the list of error codes. ( Page 15 List of error codes)

The operation results of the subtraction that has been completed before i_bEN (execution command) is turned off remain

stored in the file register (ZR).

(13)When a single-precision real number is set in i_uDataType (data type selection) and the operation result exceeds the

scope of the single-precision real number, o_bErr (error completion) turns on and the processing of the FB is interrupted.

In addition, 203H is stored in o_uErrId (error code) in one scan. For the error code, refer to the list of error codes. (
