The Write to Network instruction is used to
write a block of data from the master
device to a slave device on the same
network. The function parameters are
loaded into the accumulator and the first
and second level of the stack. Listed below
are the program steps necessary to
execute the Write to Network function.
Step 1: — Load the slave address (0–90 BCD) into the low byte and “F2” into the
high byte of the accumulator (the next two instructions push this word down to the
second layer of the stack).
Step 2: — Load the number of bytes to be transferred into the accumulator (the
next instruction pushes this word onto the top of the stack).
Step 3: — Load the starting Master CPU address into the accumulator. This is the
memory location where the data will be written from. This parameter requires a
HEX value.
Step 4: — Insert the WX instruction which specifies the starting V memory location
(Aaaa) where the data will be written to in the slave.
Helpful Hint: — For parameters that require HEX values, the LDA instruction can
be used to convert an octal address to the HEX equivalent and load the value into
the accumulator.
