F153_RMWT

Write data into the slave station

This instruction writes data into the specified intelligent unit of the MEWNET-F slave station.

Parameters

Input

s1_Control (DWORD): Stores control data for master/slave configuration
s2_Start (WORD, INT, UINT): Starting 16-bit area in CPU where words are read
n_Number (INT): Number of words to be read and then written to the slave unit (max. 32 words)
d_Start (WORD, INT, UINT): Starting memory address number in the intelligent unit where words are written

The variables s2_Start and d_Start have to be of the same data type.

Remarks

Please refer to F152_RMRD

s1_Control stores the control data for the configuration of the master and slave units in the network. n words, beginning at the address in the CPU specified by s2_Start, are written to the intelligent unit of the slave unit beginning at the shared memory address number specified by d_Start.

Specifications of s1_Control:

(1) s1 higher word
(2) Bit
(3) s1 higher word
(4) Bank No. (16#00–16#FF if there is a bank to specify, otherwise 16#00)
(5) Slot No. (16#00–16#1F, FP3: 16#00–16#17)
(6) s1 lower word
(7) s1 lower word
(8) Master station No.(16#01–16#04)
(9) Slave station No. (16#01–16#20)

Tip

Intelligent unit with bank: FP3 expansion data memory unit

Order number: AFP32091 AFP32092

Error flags

sys_bIsOperationErrorHold (turns to TRUE and remains TRUE)

if the control data s1_Control exceeds the limit of specified range
if no MEWNET-F master unit is found
if the data read exceeds the area of s2_Start

sys_bIsOperationErrorNonHold (turns to TRUE for one scan)

if the control data s1_Control exceeds the limit of specified range
if no MEWNET-F master unit is found
if the data read exceeds the area of s2_Start
