Writing Data to Standard ROM (SP.DEVST)

SP.DEVST

*1:Devices assigned as local devices can not be used.

Function

(1) Writes device data for the number of points specified at n2 of the device

to the write

offset, which is specified for n1, of the device data storage file in the standard ROM.
n1 is the offset from the head of device data storage file and specified by word offset (in units
of 16-bit words).

(2) Since the device data write position completion device (

+0) in the standard ROM

automatically turns ON at execution of the END instruction, which detects the completion of
this instruction, and turns OFF with the END instruction of next scan, it is used as an
execution completion flag of this instruction.

(3) When this instruction is completed in error, the error completion device (

+1) turns ON/

OFF at the same timing with the completion device (

+0). This device is used as an error

completion flag of this instruction.

n1: Write offset of the device data storage file (specified in units of 16-bit words) (BIN 32-bit)

: Head device number written to the standard ROM (device name)

n2: The number of write points (BIN 16-bit)

+0 : FCompletion device (bit)

+1 : FError completion device (bit)
